Lexus LFA
The new Lexus LFA marks an important moment in the history of both the Lexus and the development of the supercar. A true "clean sheet" design, the Lexus LFA has been created by a small team, passionate and dedicated engineers whose achievement has been to expand the boundaries of materials and engineering technologies at all stages in the production of a car like no other to bring the Lexus badge.
Constructed with advanced carbon fiber technology, rear-wheel drive Lexus LFA is powered by a measure, high-revving 552bhp 4.8-liter naturally aspirated V10 engine mated to a rear-mounted six-speed sequential automatic, giving 200 mph, plus a performance.
In the words of Chief Engineer Haruhiko Tanahashi: "The Lexus LFA is a thoroughbred supercar, a machine designed to achieve one goal - to provide supreme driving experience over the last decade we have pushed all boundaries in pursuit of this goal and me . We believe we have made the car more driver-oriented as possible. "
LEXUS LFA CARBON FIBER CONSTRUCTION
Keep vehicle weight to an absolute minimum was one of the defining elements in the development of the Lexus LFA and this led to the decision to change the use of aluminum for the construction of the machine advanced carbon fiber reinforced plastic (CFRP) for the frame and the body.
In addition, Lexus decided the CFRP structure should be built at home rather than from a third party vendor. In doing so, he invoked the legacy of Toyota Motor Corporation in textile technology to push the limits of their technical skills, development of new carbon fiber chassis and a laser system to monitor the integrity of the material.
At four times the strength of aluminum, carbon fiber gives the Lexus LFA incredibly rigid and strong, and also offers great advantages in weight, saving about 100 pounds in a body of aluminum equivalent. CFRP accounts for 65 percent of the body-on-white, with aluminum alloy used for the remaining 35 percent.
Unlike the few vehicles on the construction market that the use of CFRP, the Lexus LFA uses the same technology favored by the resin-edge aerospace programs for unrivaled weight and resistance.
Lexus LFA MOTOR
The heart of the Lexus LFA is a custom engine, naturally aspirated V10 engine that sets new standards for compact size, lightness and spirited performance.From the outset it was determined that the engine must have a capacity of 4805 cc, developing 552bhp at 9,000 rpm and turn a line of red tears. An angle of 72 degrees between the cylinder heads is ideal for achieving a balance in the engine exceptionally smooth, while providing individual, electronically controlled butterfly valves for each cylinder gives excellent response of the throttle valve.
The use of a dry sump lubrication allows the block to be placed deep in the engine compartment, reducing the car's center of gravity and moment of inertia, and allowing the engine to operate continuously at high speed on curves.
The V10 produces 480 Nm of torque at 6800 rpm, 90 percent of which is available from 3,700 rpm to 9,000 rpm red line, thanks to Dual VVT-i technology, exhaust manifolds of higher volumes long and 12-hole injectors. This gives the acceleration browning hear any engine speed in any gear: zero to 62 mph in just 3.7 seconds and top speed is 202 mph.
Weight of 1,480 kg, the Lexus LFA has a power to weight ratio of 373bhp per ton, while the specific production of 115 hp per liter is the highest of any supercar in progress, with the help of a high percentage, compression 12: 1, low internal friction and the optimized consumption and the exhaust stream.
Despite its power, the V10 is a lesson in a compact and lightweight, with about the same size as the normal V8 engine and weighs almost as much as conventional V6. It 'also reliable and refined as any other Lexus power plan and exceeds Euro 5 emission standards.
The engine was developed in collaboration with Yamaha in collaboration with collaboration between Toyota Motor Corporation and the engineering company specializing in Japanese.
Lexus LFA TRANSMISSION
The impressive performance of the V10 is managed through an equally advanced transmission, a design goal of the six-speed sequential automatic gearbox (ASG), which drives the rear wheels through a limited slip differential. To obtain optimum front to rear weight distribution of 48:52, which is contained in a transaxle mounted on the rear axle.
The ASG is operated gearshift mounted on the steering column and is designed to move exceptionally fast: an upshift can be done in about 0.2 seconds.
The system features four driving modes: Auto, Sport, Normal and Wet, activated by a switch on the dashboard. Each mode has a specific program of change of gear, and the motor and the control logic of the brake for the tailor the performance of the machine controller to adapt to the driving conditions.
Lexus LFA SOUND
The acoustics of the Lexus LFA, the induction system and exhaust notes have been specially tuned to deliver an impressive "soundtrack" that expresses extreme performance of the car, both outside and inside the cabin. Known for hearing aids as "Octave Harmony", is inspired by the sound of a Formula 1 engine at full throttle and does not resemble that of any other road car, with different harmonic qualities created as the motor moves toward its maximum 9000 rpm.
Lexus LFA BRAKE
The Lexus LFA is one of the most advanced and powerful brakes fitted to any production car, adequate to meet the demands of their performance capability over 200 mph.
The brake discs are carbon-ceramic (CCM), as well as being lighter than steel, offering fade-free performance in all conditions. The front discs are 390 mm thick and 34 mm diameter aluminum calipers trapped by six-piston, the extension of the rear discs with a diameter of 306 mm, thickness 28 mm and are equipped with four-piston calipers. Any use of a micron of high friction pads, made exclusively for use with CCM brakes.
SUSPENSION, WHEELS AND TYRES
The track at the point of suspension is the result of intensive development work carried out by Lexus on the Nurburgring Nordschleife circuit to give the best possible balance between comfort and control.
The front fork as / multilink rear design makes extensive use of aluminum alloys with high strength and low weight, and aluminum monotube dampers are the same Lexus used for circuit racing cars LFA Nurburgring 24 hour race.
The 20-inch BBS forged aluminum wheels are shod with Bridgestone tires asymmetric: 265/35ZR20 front and 305/20ZR20 at the rear.
AERODYNAMICS
The Lexus LFA is first class aerodynamics, obtaining an excellent cooling transmission and processing at high speed and stability. Numerous wind tunnel tests helped to produce a wind-cheating profile with a coefficient of drag of 0.31, a remarkable achievement, given the level of the car creates downforce at high speeds.
The airflow is carefully checked over, under and around the car. A carbon fiber rear diffuser and underbody downforce generating flat-significant, with an active rear wing with Gurney flap on the front line, raising the level even more.
ADDRESS
Career guidance contained offers an excellent response and feedback to create a dynamic link between the perfect car and driver. The rack and pinion constant speed system uses an innovative assistance system of the electric power steering column that does not compromise the performance of the engine.
The axis of the column of large diameter is mounted directly on the structure of the central frame, giving the stiffness of the layout exceptional address. The carbon fiber steering wheel has a flat bottom section houses the key to start the engine and information tool selector switch. It can be adjusted for reach and rake.
Lexus LFA EXTERIOR DESIGN
Dictated by its front engine design step in the medium and short overhangs, sophisticated aerodynamics and low cabin, Lexus LFA flow lines from the roof to the threshold of a perfect convex to concave line. In addition to its light weight and high strength carbon fiber reinforced plastic (CFRP) also gave designers greater freedom to create shapes, curves and edges that were not possible with metal.
The style remains true, however, the principles of L-finesse, the logic was behind all current Lexus models. Form follows function, as shown n air intakes and many aerodynamic details, and also the design of the exterior mirrors, shaped to channel the air over the shoulders of the rear car jacks.
Lexus LFA INTERIOR DESIGN
The low cab height is divided into three areas: the mechanics of the area, including the skeleton of the construction of the machine, the human zone, with two seats right in the center of the machine and the pilot area with high-technology that brings driver and car together.
The cabin is built by hand, with particular attention to the ergonomics of the driver.The seats, upholstered in fine leather and Alcantara, provide the highest level of back support and side need a machine capable of 200 mph-plus performance.The setting echoes the advanced materials used to build the Lexus LFA, with exposed parts of matte and luster of carbon fiber. Trim details are finished in shiny metal folding top and the brake and accelerator pedals are aluminum forgings. As for the exterior finish, owners can choose different colors for the interiors and details to suit your personal taste.
LEXUS LFA INSTRUMENTATION
The compact instrument panel with LCD display combines a hood with a color film transistor (TFT) and a cell phone ring motor. It has a single circular dial with a central speedometer with a needle LCD. When the engine speed exceeds 9,000 rpm, the area becomes red to trigger a change of the engine above. It can also be programmed to turn yellow or green as the revs reach a user-selected range. The line also features a digital speedometer and gear indicator, transmission mode, data from the vehicle control and travel information screens.
An information selector on the left side of the steering wheel allows the driver to go through a series of functions, including customizing data visualization, adjusting the lighting in the cabin and operate a satellite-ready clock.
When the machine is started, a sequence of display device is activated, creates a sense of occasion, culminating in the four digital dials showing oil and water temperature, fuel level and oil pressure radiating center of the counter to take their positions on both sides of the central sphere.
Lexus LFA SAFETY
Active and passive safety measures are in line with the outstanding performance of the Lexus LFA. The structure of carbon fiber reinforced plastic core is very strong and offers excellent impact protection. Crash boxes are mounted front and rear that are designed to deform in a controlled manner in the case of an impact.This front part is made of carbon fiber, which in the rear of extruded aluminum.Side impact protection includes strong and rigid carbon fiber spars and door structures comprising an inner panel made of aluminum and glass fiber reinforced sheet molding compound (SMC-G) outer skin.
The Lexus LFA Lexus vehicles equipped with Dynamics Integrated Management (VDIM), which coordinates the operation of ABS, vehicle stability and traction control systems when the vehicle is near its performance limits based on critical data on the operation of the brake rates , orientation and roll speed of each wheel and the longitudinal acceleration, lateral and vertical
Passive safety systems include front airbags and seat belts double adaptive airbags for driver and front passenger knee airbags for the driver.
Lexus LFA production and sales
Lexus LFA program was launched in 2000 as a simple project of R & D, but gained momentum with the appointment of Haruhiko Tanahashi to lead a team of dedicated engineers, engaged in a development program, including Lexus. The first Lexus LFA prototypewas completed in 2003 and a design studio made its public debut at the Detroit Motor Show 2005. In 2008 and 2009, the Lexus LFA has been introduced in the Nurburgring 24 hours race, with the intention of pushing the car under test conditions before its official launch as a production-ready model 2009 Tokyo Auto Show.
The Lexus LFA is hand-assembled at the Motomachi plant in Toyota City. Only 500 units will be constructed at a maximum speed of 20 per month to ensure the construction of better quality and attention to detail. Each V10 engine will be fitted by a single technician, and bear his signature as witness to the situation as every Lexus LFA.
The launch price in the UK for the Lexus LFA is € 368,000 (£ 336,000 approx).Owners can choose from a wide range of options to customize your car, including 30 different paints. Some items of standard equipment can also be removed, as the audio system, to reduce the weight of the car.

 Ferrari FF review 

Il 81 Geneva International Motor Show ha ospitato l'inaugurazione di due innovazioni importanti novità Cavallino Rampante: la rivoluzionaria Ferrari FF, una trazione integrale quattro posti con un V12 anteriore-centrale che è il più potente e versatile Ferrari abbia mai costruito , e la 458 Italia HELE sportive del (grandi emozioni basse emissioni) del sistema che taglia CO2 a soli 275 g / km.

La Ferrari FF fa il suo debutto atteso con impazienza, a Ginevra, dopo l'enorme accumulo di attesa e di interesse suscitato dalla prima cliente a Maranello trasmissione in linea da www.ferrari.com.

La rivoluzionaria Ferrari FF propone una completamente nuova assumere il tema sportiva Gran Turismo. Non è solo la prima Ferrari a quattro ruote motrici, ma, più significativamente, un modello che saluta una grande rottura con il passato, mescolando senza sforzo estremo vettura sportiva prestazioni con la versatilità e la fruibilità di una GT vera e vantando un design estremamente innovativo .

Ogni singola area della Ferrari FF è ricca di innovazione, non ultimo il suo motore, il primo V12 GDI da accoppiare con la F1 a sette marce a doppia frizione. Il V12 scatena una massiccia 660 CV a 8.000 giri e una coppia massima di 683 Nm a 6.000 giri con 500 Nm già disponibili a soli 1.000 giri. In questo modo i dati relativi alle prestazioni di una sportiva estrema, con il 0-100 km / h sprint coperto in 3,7 secondi e una velocità massima di 335 km / h.L'efficienza è stato notevolmente potenziato anche con il consumo di carburante ora in piedi a soli 15,4 litri per 100 km, ed emissioni di CO2 a 360 g / km, un 25 per cento di riduzione rispetto ai precedenti V12, grazie in parte alla HELE (emozioni-High basse emissioni) che integra tecnologia Stop & Start.

Unicamente, la Ferrari FF garantisce prestazioni eccezionali anche questo su terreni con coefficienti di aderenza molto bassi, grazie alla Ferrari proprio 4RM brevettata a quattro ruote motrici. La coppia viene ancora consegnato dalle ruote posteriori, ma il PTU (Transfer Unit Power) assicura che quanto è richiesto viene trasferita anche alle ruote anteriori quando necessario su superfici a bassa aderenza. Il FF Ferrari distribuisce in modo intelligente coppia a ciascuno dei quattro ruote singolarmente, grazie al fatto che tutti i comandi del veicolo dinamici (E-Diff, F1-Trac e PTU) sono stati integrati in una singola CPU.

Eccezionale guida sportiva è garantita dalla architettura transaxle del FF Ferrari (metà anteriore del motore con riduttore sull'assale posteriore) e il posizionamento del 53% del peso alla parte posteriore della macchina.Meticolosa attenzione è stata presa per alleggerire il motore (getti nuovi), carrozzeria (nuove leghe di alluminio e processi di produzione) e una serie di altri componenti. L'interno è stato inoltre ottimizzato attraverso l'utilizzo di materiali high-tech come il magnesio per i sedili. Terza generazione di Brembo in carbo-ceramica freni sono ora più leggero e più duraturo, con l'usura praticamente trascurabile durante il normale utilizzo su strada. Tutte queste innovazioni si sono combinati per produrre una assolutamente eccezionale rapporto peso-potenza di 2,7 kg / CV, un nuovo punto di riferimento per questo tipo di vettura.

Disegnato da Pininfarina, la Ferrari FF senza sforzo le linee riflettono il suo equilibrio senza compromessi firma di sportività e versatilità. Può ospitare comodamente quattro nelle sue sedi bodyhugging e cabina spaziosa. Il suo avvio 450 litri può essere esteso anche a 800 litri, i sedili posteriori si ripiegano in modo indipendente. Ciò significa che la Ferrari FF offre più spazio bagaglio non solo di qualsiasi altra vettura della sua categoria, ma anche molte berline a quattro porte, anche.

Tutto a bordo della Ferrari FF concepito specificamente per le esigenze ei gusti di chi la guida con una scelta di sei colori esclusivi e raffinati le pelli anilina Frau appositamente trattati per migliorare la loro naturale morbidezza. L'eccezionale specifica FF Ferrari migliora il tuo divertimento per tutti e quattro gli occupanti. Le caratteristiche includono un nuovo sedile posteriore sistema di infotainment con due schermi per guardare la TV e DVD e di un 1280 Watt, sistema a 16 canali stereo con audio Dolby Surround.

I tre FF presso lo stand di Ginevra sono uniti da un 458 Italia, la 599 GTB Fiorano HGTE con il pacchetto sportivo, e una Ferrari California in un elegante Blu Tour De France finitura. La Ferrari California si sta godendo incredibile successo di vendite ed è anche il soggetto del modello alla più ampia gamma di richieste di personalizzazione in Ferrari line-up. Il motore V8 convertibile è, in realtà, molto popolare nella speciale bicolore a tre strati e finiture opzione vernice, con ulteriori combinazioni originali interni di materiali, colori e soluzioni di assetto. Lo straordinario successo della Ferrari California testimonia il richiamo perenne e sofisticato.

porsche boxster 2013

 Porsche Boxster

Porsche boxter 2013 more prefomance- with a new body and chassis design entirely new light, the latest generation Porsche Boxster is the creation of new performance scores for Smart Porsche.

Significantly less weight, a longer wheelbase, wider track and larger wheels significantly improve the driving dynamics of the mid-engine sports car even more, because by far the best in its class, with the support of the new steeringelectro-mechanical system. As a further impetus to driving dynamics, Porsche offered as an optional Sport Chrono package for the Boxster, with the dynamic drive assemblies for the first time. Another novelty is the Boxster Porsche Torque Vectoring (PTV) with a mechanical rear axle differential locking.

The new Boxster offers superior performance and up to 15 percent more fuel efficient. They boast of ultra-modern direct injection, six-cylinder engine variants all get by with less than nine liters of fuel per 100 kilometers, the Porsche Boxster with PDK even less than eight liters of management. The most important data at a glance:

Porsche Boxster 2.7-liter boxer engine with 265 hp (195 kW), rear-wheel drive six-speed manual, optional seven-speed Porsche-Doppelkupplung (PDK), acceleration from 0 to 100 km / h in 5.8 seconds with PDK in 5 , 7 seconds (5.5 seconds with optional Sport Chrono), top speed 264 kmh, 262 kmh with PDK, fuel consumption (NEDC) 8.2 l/100 km, CO2 emissions 192 g / km, with PDK 7.7 l/100 km CO2 of 180 g / km.

Porsche Boxster S: 3.4-liter boxer engine 315 hp (232 kW), rear-wheel drive, six-speed manual, optional seven-speed Porsche-Doppelkupplung (PDK), acceleration from 0 to 100 kmh in 5.1 seconds with the PDK in 5.0 seconds ( 4.8 seconds with optional Sport Chrono), top speed 279 kmh, 277 kmh with PDK, fuel consumption (NEDC) 8.8 l/100 km, CO2 emissions 206 g / km, with PDK 8.0 l / 100 km of CO2 188 g / km.

Never before in the history of the Porsche Boxster has been a change in the generation of so large and so obvious at first sight clear: The change in proportions is durable. For example, the pitch is increased by 60 millimeters and the width of the track in front to 40 mm and in the rear by a maximum of 18 millimeters, as a result of which the wheels aligned flush with the body. The windshield is flatter and set approximately 100 mm below, all the Boxster is up to 13 mm lower. Together with its convertible line extended far to the rear, the new Boxster cuts an elegant silhouette. Another factor that contributes to more than the sporting aspect is that the body is only 32 mm longer than before, while at the same time the projection on the front was reduced by 27 mm: the Porsche Boxster roadster remains compact.

duo porsche boxster

Better design is typical of the shoulder line, which extends from the band strongly curved upward in front and rear side section fits even the exterior mirrors, now in the vicinity of the upper edge of the door. In particular, expression and character is the return of a new dynamic in the door, which guides the air intake to the power evident in the back: you can see when the heart beats the roadster.

The new Porsche Boxster front end is dominated by the radiator side air intakes and larger headlights. Both halogen headlights, standard on the Boxster and the new Bi-Xenon headlights, the standard for Porsche Boxster S, were completely rebuilt. I also redesigned headlights with daytime running lights and LED position are integrated on the air intakes on strike.

The rear part of the new Porsche has been completely redesigned: there is no longer soft top compartment cover, rear spoiler and the lights are joined by a prominent ridge which covers the entire width of the vehicle units and the central lamp, below it combines the light fog and reversing lights in a flat strip. The new tail lights, all in LED technology are fully integrated into the rear bumper with its curve around the corner from the car. The redesigned exhaust pipes complete the look deep and focused. This is accentuated by the issuer, which covers the width of the vehicle. A feature of the Boxster is an oval tailpipe, the Boxster S has a dual-flow dual exhaust.

Porsche Boxster Engine and transmission

The Porsche Boxster mid-engine concept was the key reason for its exceptional agility of the roadster of all time. In addition, flat-six engines with economic performance, located on the rear axle, making the two-seater performance and efficiency to the Porsche.

The new Boxster models have opened a new chapter here. Models both engines are more powerful than before, on the one hand, while being more than 15 percent of fuel more efficient, regardless of the model, on the other side.

Porsche Intelligent Performance: more effective reduction of cabotage

The engine of the Porsche Boxster has been derived from the car the Boxster S in accordance with the principle of downsizing and has a displacement of 2.7 liters - 0.2 liters less than its predecessor. To increase the efficiency, boxer engines have restoration of the electrical system and controlled by the map management of the cooling water temperature. In addition, Porsche introduced the Auto Start / Stop function for the KDP and the manual gearbox in the Boxster as well.

The Porsche Boxster with PDK is the only loan on the basis of engine power when it is actually the new 911 Carrera: the so-called cabotage. What is Cabotage is rolled along, without power, with the engine idling and low fuel consumption at high altitude. In practice, this means a fuel saving of up to one liter per 100 kilometers with a visionary style of leadership in driving all day.

A six-speed manual or Doppelkupplung (PDK)

A six-speed manual transmission is standard on the new Boxster models, the gear ratios that are optimally matched to the characteristics of the engine. The redesigned Porsche PDK widely available as an option, offers seven courses, gear changes with no interruption in the flow of energy in making a quick shot and fuel economy. In combination with the characteristics associated with the chassis and engines, the new Boxster with PDK offers completely new driving experience.

New: Chrono Package, for the first time the dynamic transmission mounts

porsche boxster test drive

The optional Sport Chrono package, which now includes dynamic media drive for the first time, makes a large difference between a sports facility - for example, for the track - and comfort in everyday driving. Change their stiffness and damping characteristics according to the driving situation. The system thus ensures that the unit of power is optimally attuned to the body in every driving situation, thus contributing to improved handling characteristics accompanied by a high degree of ride comfort and vibration. In addition, the Sport Chrono package in conjunction with PDK Launch Control function provides for acceleration of departure to the better. The vehicle takes less then 0.2 seconds for zero to 100 km / h in normal mode.
Porsche Boxster chassis and brakes
As a mid-engined sports car, the Porsche Boxster has been blessed with extraordinary agility, from the cradle. The two places of this new frame reaches a level that puts even the agility previous Boxster in the shade.
The basic geometry alone creates the best conditions for this: the 60 mm longer wheelbase for greater stability at high speeds, a wider track on both axes for extra driving stability and agility in the corners, larger tires for new membership to the edge of the envelope. Proof: When equipped for optimum driving dynamics, the new Boxster S around the Nürburgring-Nordschleife in 7:58 minutes. This is the twelve seconds faster than the previous model, relatively equipped. Options like the best Porsche Active Suspension Management (PASM) and Porsche Dynamic Suspension Engine Torque Vectoring (PTV) and the optional 20-inch wheels for maximum load capacity.
Speedy and efficient electro-mechanical steering
The new Porsche to further improve the agility and response speed has been reduced to the electromechanical power steering, that Porsche first used for the generation of new 911 Carrera. The fundamental advantage over hydraulic power steering is the reduction of fuel consumption at least 0.1 liters per 100 km. Other features further enhance comfort and safety. Specific feedback is passed to the driver via the steering wheel and unnecessary negative influences or filtered.
More traction, dynamic cornering Porsche Torque Vectoring (PTV)
Previously, mechanical locking differential rear wheel drive Boxster optimized application. The new carrier Torque Porsche (PTV), available in combination with PASM, it should be a better, improving the dynamics of the curves from the time when the vehicle enters the curve. Basically, PTV improves steering behavior and precision steering of the vehicle selectively braking the inner rear wheel. As for the dynamics and driving stability, PTV is the ideal complement for the Porsche Stability Management (PSM). Whereas the PSM uses brake intervention to stabilize the vehicle, if necessary, use PTV braking interventions to improve the driving dynamics and agility. The mechanical locking rear differential is included in the PTV, as in the previous model, asymmetric blocking action of 22 percent and 27 percent in traction for propulsion.
PASM renovated with better sensors
The restructuring and the ongoing development of the system PASM active suspension option that best suits the dynamics of the Boxster. Unlike previous models, four additional sensors in the vertical front and rear wheels provide better, more responsive control. As before, the driver can choose between two programs, "Normal" and "Sport" and select the PASM button on the center console.
News: better brakes and electric parking brake
Improved performance was also accompanied by a more powerful braking system - a fact with the Porsche. Together with clamps new and more serious on the front axle, brake pads optimized brake and a larger surface, the cooling of the brake disc is also improved. In addition, the new Porsche Boxster S also has large brake discs front axle, taken from the 911 Carrera. For safety reasons, the increase in traffic and to provide a warning better for the following traffic, the light pulses Boxster brake system as soon as the ABS control is activated. As another Porsche model line, the new models Boxster time of a parking brake to the electric drive, which can be conveniently activated by a button on the left of the dashboard. Like its predecessor, the powerful, proven race Porsche Ceramic Composite Brake (PCCB) is available as an option.
The larger wheels and tires with low rolling resistance
The new Porsche Boxster models running on the new development, 18 and 19 inch tires as standard. The generation of the new tire has been optimized for rolling resistance and performance typical of Porsche with respect to the handling and braking distance and weight. The reduction in rolling resistance of seven percent over previous models helps reduce fuel consumption. Handling characteristics, and the fun of driving, thereby greatly improved by increasing the rolling circle in the front and rear of a 4 percent over previous models.
Body and cap
One of the key development objectives for the next generation Boxster with a strong impact on the consumption of performance, agile handling, and fuel and CO2 emissions are a significant weight reduction. Initially, however, on the basis of previous models, the most stringent safety requirements and the torsional stiffness has meant an increase in weight up to 20 kg depending on model.
Thanks to its clever design, lightweight, however, it was possible to reduce the existing vehicles with a gross weight new Boxster models for a maximum of 35 kg compared to previous models: the new Boxster is the lightest in its class sports car.
Improved aerodynamics and a new rear wing concept
The new Porsche Boxster is not only surprising, but it offers aerodynamic advantages, and even if the more powerful engine and the brakes require a cooling system changed, the drag coefficient is a good record = 0.30. It was possible to reduce the increase in both the major axes than the previous model, which results in even greater driving stability at high speeds. At the rear, the new rear wing and wraparound edge separation has a decisive role in this. Creates an increase of separation downforce edge in the first expansion, and offers a lower resistance to air flow.
The new convertible top compartment cover of the roof without
The new Boxster design have a decisive influence on the interaction between the windshield plate, below, and the new, extended convertible top, which now extends all the way near the rear wheels. Even when open, the difference with its predecessor is unmistakable: Since no convertible top compartment cover, making the car look lighter.
Top of the Boxster convertible has been completely redesigned. The long, elegant and sporty sedan is distinguished by its long 120 mm. The concept of basic technique has been adopted by the previous Boxster Porsche has become an all-electric convertible roof. The hood can be opened or closed by a switch on the center console with speeds up to 50 km / h in no more than nine seconds. Also in this case, the speed of Boxster is insurmountable.
Porsche Boxster Interior and equipment
The Porsche Boxster interior architecture has been completely redesigned, but it is familiar to any driver for Porsche in its basic functions. The result is a sophisticated new interior design, with clean lines influenced by the super sports car Carrera GT.
The center console tilted upwards, with his style of running high and Enclosures offers the driver the feeling of being increasingly integrated. The short distances between the steering wheel and gear lever or selector make for a sense of emphasis on sports. The functions and settings important to the operation of the vehicle are grouped into logical groups on the center console. This button configuration allows a fast, intuitive operation of each function.
The new top center position of the RDF standard audio system with seven-inch touch screen is not only highly visible but also provides easy access to many functions. The three instruments Boxster model line round the central counter and the power switch on the left of the steering wheel provides the link to the family cabin environment. Also new is the 4.6 "VGA screen on the right multifunction. News more important for the functions of the onboard computer, the display offers a screen capture of the map with the optional Navigation PCM, for example.
The new sports seats with a seat five millimeters lower, more leg room offers the driver and front passenger, plus long-distance comfort and support the positive side of being conducted with a dynamic driving style. Compared to previous models, the legroom is increased by 25 mm for the comfort and cabin space. As before, the steering wheel is mechanically adjustable in height and depth, with the field of longitudinal adjustment increased by ten millimeters. This allows the driver's seat to further adjust individually and accurately.
Porsche Boxster program: proven and new optional accessories
The wide range of interior options offer many ways to identify new Boxster models to your personal taste. For example, the different families until the plus adaptive sports seats are available. There is also a choice of leather upholstery in different versions.
Porsche offers two sound systems as an alternative to the CDR as a standard.The optional Sound Package Plus is composed of seven speakers, divided into five channels, and an external amplifier with a total power of 185 watts. The top of the range is optional Bose ® Surround Sound System with a total of 10 speakers, amplifier powered by eight channels.BOSE Digital ® surround sound system with a total of 10 speakers, powered by eight channels of digital amplification.

BMW Z4

The combination of classic proportions with modern sportiness, the new BMW Z4 has reached the top of its market share overnight. And now this charismatic roadster is entering a new dimension of driving dynamics, the new BMW Z4 sDrive35is offers an even higher level of performance is guaranteed by the change in power six-cylinder BMW Twin Turbo technology and High Precision Injection, on the one hand, BMW and seven-speed sports automatic with double clutch operation and the M sports package includes adaptive M suspension also standard on the other. The optimization of the box in engine technology increases the maximum output of 3.0 liters 250 kW/340 hp. Maximum torque is 450 lb-ft Newton-metres/332, increasing slightly with overboost to 500 lb-ft Newton-metres/369. The outstanding power performance and Z4 sDrive35is is expressed, in particular the significant increase in traction and muscle clearly be experienced in all situations. In collaboration with the performance of seven-speed automatic transmission with double 

clutch sport, new flagship

Roadster accelerates to 100 km / h (62 mph) in just 4.8 seconds.

The 9.0 l/100 km (equivalent to 26.1 mpg U.S.) and 210 grams in the EU test cycle, fuel consumption and CO2 emissions are the same as the BMW Z4 sDrive35i with Sport Automatic.

The BMW Z4 sDrive35is is making its world premiere at the 2010 American International Auto Show (NAIAS) in Detroit. And parallel with the implementation of this high-performance roadster in spring 2010, the M Sports package was introduced for all other versions of the BMW Z4.

More air, more boost, more torque, more driving pleasure.

The twin-turbo in-line six-cylinder power is already giving the BMW Z4 sDrive35i truly impressive and dynamic performance throughout the year is especially notable for its direct and spontaneous response to accelerator pedal revolutions and fascinating free to use the performance of the economy exceptionally fuel for a car of this class.

Now, the extraordinary potential of this engine was first used even the new version of the BMW Roadster, features such as air supply and optimized turbo pressure increase to ensure a better flow of energy with the same high level of efficiency.

The precise combination of injection and BMW Turbo Twin provides a high level of performance of a propeller suction only be able to provide a greater number of cylinders in multiples and displacement, ie, much greater weight and fuel consumption significantly higher.

In contrast, the BMW Twin Turbo unit uses two small dimensions power turbocharger, thanks to their low inertia, cut from the start of the engine at relatively low speeds, each providing three cylinders with compressed air.Consequently, the power and performance are built with an unusual degree of spontaneity in a turbo engine. The turbocharger system developed by the motor in Z4 sDrive35is maintains a high supply pressure in the range of full load. Maximum torque increased to 450 Newton meters or 332 pounds-ft comes from a low 1400 rpm and remains constant up to 4,500 rpm. The maximum output of 250 hp kW/340, in turn, comes to 5800 rpm.

The impulse function for particularly dynamic acceleration.

Modifying the engine management Z4 sDrive35is also allows the use of a function of overboost briefly increase the torque of the engine at full load for 50 Nm and 37 lb-ft. The peak 500 pound-feet offered Newton-metres/369 gives the car accelerates very fast, dynamic and powerful, the BMW Z4 sDrive35is complete the sprint from rest to 100 km / h (62 mph) in just 4, 8 seconds.

Through its special features, the engine delivers a strong performance especially this supreme. Additional production of six-cylinder engine optimization remains constant at all load ranges, especially in highly dynamic driving conditions.

When the acceleration of the BMW Z4 sDrive35is, the controller considers the additional torque and muscle particularly in engine speed, medium and high. After the policy of the BMW Group, finally, the BMW Z4 sDrive35is speed is electronically limited to 250 kmh 155 mph.

High Precision Injection: the effectiveness of performance.

The BMW Z4 sDrive35is offers its power and performance you can at any time.But that does not mean an increase in fuel consumption and emissions. On the contrary - the average consumption of 9.0 l/100 km (equivalent to 26.1 mpg U.S.) and CO2 emissions of 210 grams per kilometer in the EU test cycle, the new flagship also offers the same superior accordingly, as the BMW Z4 sDrive35i with Sport Automatic.

This unusually good balance performance and fuel economy results from the basic design and layout of the fastest six-cylinder BMW Twin Turbo and High Precision Injection. Then, once more, the quality of the gasoline direct injection engine out, even this very clearly piezo-injectors positioned in the cylinder head between the valves and, then, near the spark plug ensure a count special needsfuel and a combustion process clean.

The opening to the outside nozzles operate at a pressure of 200 bar, distribution of fuel in a spray cone of the combustion chamber. A further advantage of this direct injection is the cooling effect that allows for greater compression and making the process even more efficient combustion.

Through its concept alone, turbochargers also help reduce fuel consumption.Since the turbine are of special steel is particularly resistant to high temperatures and therefore able to withstand temperatures of over 1000 ° C or 1830 ° F, there is no need to supply fuel with higher cooling effect. In particular, full load advantagein this provides a significant saving of fuel. best car insurance for you click here

Other technologies that are standard to the BMW EfficientDynamics Brake Energy Regeneration, EPS Electric Power Steering and demand-control and management of ancillary units also help reduce fuel consumption and emissions.

Dynamic typical engine sound accompanying the wave energy.

The modification of six cylinders are equipped with special characteristics of the engine block itself, in the interests of greater strength and stiffness. The exhaust system of the BMW Z4 sDrive35is, in turn, was developed specifically for this model, appropriate sound engineering giving the car a model sounds very strange and very impressive.

This distinction is especially designed for the BMW Z4 sDrive35is is ensured by special sound flaps and modifications to the silencers. The driver and passengers, for problems of acoustic feedback powerful desire for performance without the annoying sound of the engine, not to mention boring, at any time. Thus, the sound experience is characterized by a particularly deep diamond with particular attention to the narrow frequency range.

 Sport seven-speed automatic with a map and special monitoring optimized dual wheel.

The seven-speed sports automatic with double clutch operation in the BMW Z4 sDrive35is also offers the best driving dynamics and efficiency. A particular feature in this case is the twin mass flywheel, in particular, has an even higher level of energy and performance, providing greater strength and stability, of course, handling high torque motor to 500 Newton-meters feet or 369 pounds, without the slightest problem.

The seven-speed sports automatic with double clutch operation changes gear without the slightest interruption of power and torque, which gives the driver the choice of a selection of manual or automatic gears. Acceleration gear change very rapidly and ensures smooth exceptionally smooth and also serves to reduce fuel consumption and emissions.

The control map on the seven-speed sports automatic with double clutch, of course, specially designed for power and engine performance, thus enhancing the sporty BMW Z4 sDrive35is top of an even higher level. Especially when you change gears manually, and in collaboration with the Sport and Sport + modes of Dynamic Driving Control, the transmission provides a more dynamic experience through the shift points changed, the optimized selection of gears and a further increase in the pair before to change.

The sport also has an automatic release for maximum performance when accelerating from rest.

Sport automatic transmission is designed and controlled by a selector of electronic equipment in the center console and is equipped with paddles on the steering wheel.

Featured as standard on the BMW Z4 sDrive35is: M Sports Package and adaptive suspension M.

The BMW Z4 sDrive35is is also a package includes the standard M Sport aerodynamic package, M and M adaptive suspension with electronically controlled dampers for greater flexibility without compromising in comfort. The M sports package underlines the dynamic character of the car through its aerodynamically optimized exterior design features and custom interior. Special 18-inch alloy wheels with five spokes in combination with different size tires in front and rounded back of the sporty BMW Z4 sDrive35is, alloy wheels, 19 inches of available options.

Adaptive M Suspension lowers the entire car by 10 millimeters or almost 0.4 ", ensuring a rapid response to sudden steering maneuvers and superior accuracy should come into the fold of four gas shocks double adjustment sleeve courses of interaction, adjustable rebound . 

unit control central processing data provided by three accelerometers and adjusting the four buffers independently of one another enables the suspension to respond quickly to the smallest change of driving conditions and road. damping hardness, in turn, is adjusted from the external valves that control the flow of damping fluid, providing one or more buffers or smooth configuration in accordance with the conditions and driving conditions. reaction time of the system is extremely short with the rear shock absorbers are cleared away, so that the front wheels hit a hole or bump in the road.

The electric power steering in the BMW Z4 sDrive35is has a map of control over all sporty and dynamic, focusing on the intense and clear feedback to the driver through the measurement of energy the focus of the electric motor. Again, this allows the driver to enter bends with extreme precision at all speeds in the interest of better performance.

M sports package offers a more direct experience of the dynamic potential of the car - available as an option and also other models.

The external and internal features of the M sports package as standard on the BMW Z4 sDrive35is increases the range of dynamic potential of the car to an even higher level, and clearly displays the peculiarities of this model through its looks alone.

After the introduction of the new top model, the M Sport package is also becoming available as an option on other versions of the BMW Roadster only.The only difference is that instead of wheels exclusively for the BMW Z4 sDrive35is, other models have 18-inch M alloy wheels M Sport Package

The exterior has more information about the BMW Z4 sDrive35is includes a front bumper impressive, with a horizontal structure in the side air intakes finished in brushed aluminum, like the BMW kidney grille bars. The edges of some "of these molds fans continue to draw the radius of alloy wheels as another sign of distinction.

The rear bumper has spoken, especially the exhaust pipes and a speaker of two parts designed specifically for the new BMW Z4 sDrive35is, finished on top in body color and has a black surface grain at the bottom. The M aerodynamic package, including M Sports package is also optional on other versions of the BMW Z4 Roadster also comes with a rear bumper fiberglass metallic anthracite.

Inside the BMW Z4 sDrive35is, the driving experience is enhanced to an even higher level of functionality, such as the M leather steering wheel with shift paddles, M footrest and sports seats. The instrument panel has a gray face and mark the words "sDrive35is" model on the dashboard.

Additional features within the sDrive35is BMW Z4 is BMW Individual anthracite headlining, M door moldings, mats with colored piping and the model name "sDrive35is" as well as M interior trim in aluminum, carbon.

The M Sport package, in other versions of the BMW Z4 Roadster includes an M shifter knob for manual transmission models. At the same time, the range of leather is enhanced by a variety of color to mark the release of Z4 sDrive35is: Both the top model and all other versions are available Z4 Roadster Kansas Walnut leather to a further option.

The BMW Z4 sDrive35is comes with a choice of six body colors. Also in Alpine White and metallic colors Titanium Silver, Black Sapphire, Space Grey and Deep Blue Sea, the BMW Z4 Roadster is now available for the first time in Melbourne Red metallic.

Inside the LFX
The new Cadillac SRX LFX 3.6-liter direct-injection V-6 offers a certificate SAE 308 hp (230 kW) and 265 Nm of torque (359 Nm), with features to improve efficiency, including direct injection and continuously variable . The maximum torque is reached only at 2400 rpm and is maintained through 5,300 rpm. The LFX also E85 ethanol-capable.
"The development team faced the challenge of achieving 300 horsepower in the SRX and exceeded the target," said Liz Pilibosian, chief engineer. "The low-end torque and horsepower of the 3.6-liter engine delivers the power required is increased at the launch, on steep slopes, and in passing. The power range of the LFX engine also contributes to a better sense of change."
The engine is a technologically advanced LFX 60 degree V-6 with dual overhead camshafts and variable valve timing roof and direct injection. Support for the elements that contribute to its performance, refinement and durability are:
The cylinder block and cylinder heads are cast in aluminum for lightness.
An intake manifold composite save about 5.5 pounds (2.5 kg) the weight of a product comparable in aluminum. Also has a relatively small surface area irradiated to help maintain the excellent noise characteristics of vibration.
An integrated head / exhaust manifold design saves about 13 pounds (6 kg) from the motor in comparison with a comparable motor with separate head / exhaust manifold.
The cylinder heads have four valves per cylinder with dual overhead camshaft incorporating infinitely variable cam removal.
A drive shaft made of forged steel provides optimum resistance to the lower end, while the connecting rods are composed of metal powder that has a higher proportion of copper, which makes them stronger and allows them to be lighter.
The pistons are cast from lightweight aluminum and feature a polymer coating to reduce friction on the skirts, and full floating pins, which also help to reduce friction. Less weight in the piston reciprocating means less mass in the engine, which in turn means less inertia and greater operating efficiency.
The oil pressure operated squirters immerse the bottom of each piston and the wall which surrounds the cylinder with an additional level of cooling, which reduces friction oil.
An oil sump is more rigid than the molten aluminum to improve the stiffness of the propulsion system and reduce the vibrations of the vehicle. It is fixed to the bell transmission and the engine block, eliminating the points of vibration. Cast aluminum dampens internal engine noise better than a traditional dish of pressed steel and has a more rigid structure.
Optimized injectors flow and exhaust pipes integrated or butts promote the reduction of emissions.

To help achieve its performance targets, engineers redesigned Cadillac SRX exhaust system with two runners from the engine to a collection point further back in the vehicle. The diameter and length of the pipes are specifically adapted to improve the torque at low speeds from 1,200 to 3,000 rpm.
Discharge high pressure pulses of each of the cylinders of the engine are programmed to get to this point of collection so that the phase together in a precise manner. This effect tuning, said scanning literally strip exhaust gas from the engine synchronizing pulses of high and low pressure of each cylinder. The maximum torque is now produced in a very low 2,400 rpm and stays high all the way through 5,300 rpm. The improvements in torque and power is achieved while maintaining quiet operation.
"No stone was left unturned when it comes to optimizing the flow of air from the LFX, from the moment it enters the engine until it is exhausted through the muffler," said Pilibosian. "The exceptional qualities of the air flow that has enabled us to exceed the target of 300 horsepower, while the accurate calibration of the double continuous variable valve timing and exhaust system contribute to the high torque of the engine at low speeds."
LFX The motor is coupled with the Hydra-Matic 6T70 electronically controlled six-speed automatic transmission with tap up / down control of the driver. A wide overall ratio spread of 6.04:1 allows running "strong" first and overdrive "high" speed to cross the road at low speed. The acceleration is maximized, as is the fuel economy. The engine noise is lower during the navigation. Thanks to the diffusion of variations (6.04:1) first gear is very high, which provides a rapid acceleration from standstill. Sixth, however, is an overdrive ratio, maintaining the engine speed as low as possible to turn the motorway, which reduces the friction losses of the engine and improve fuel economy.
The operator can set the Eco function alters the shift points of the 6T70 to improve the fuel economy of up to mpg. A clutch has been added to the air conditioning compressor with variable capacity to improve the fuel economy. The compressor runs only when needed and does not offer any resistance when turned off.
Cadillac srx Chassis and Suspension
The Cadillac SRX has a four-wheel independent suspension and a standard rack and pinion steering system - and offers a variable-effort speed-sensitive steering system - with partial adjustment of the sport sedan-like driving and strong on-center feel. StabiliTrak electronic stability control is standard and works with four-wheel-disc/four-channel-ABS standard brake system.
The basic elements of the systems of frames and suspensions are the following:
An independent MacPherson strut suspension system is standard on all models, with a direct-acting stabilizer bar and hydraulic ride bushings.
An independent suspension "H-arm" rear incorporates a slight hollow aluminum lower control arm and a hollow stabilizer bar.
Power assisted rack and pinion is standard on basic collections and luxury.
It assisted speed-sensitive variable effort steering system rack and pinion is standard in performance and cost of premiums.
cadillac srx A rear axle ratio of 3.39 is standard on all models.
A towing package is available in the collections of luxury, performance and premium and increases the towing capacity of 3,500 pounds (1.587 kg).
For 2012, the base suspension provides better ride quality that has excellent handling characteristics, thanks to new media front strut best, better adjustment of the valve, the new binder front stabilizer bar bushings and two new tube rear shock absorbers to provide isolation of the road.
The active sport suspension - standard on share price and quality - has also been improved for 2012 with new front strut top mounts, valves, new shocks, bushings attached to the stabilizer bar and revised calibrations for this variable continuous-time real system of suspension damping. Electronically controlled shock absorbers at each corner "read" the road constantly to make changes in real time in milliseconds. Rate shocks delivered just right for all road conditions for comfort and a greater sense of control. This system also increases the damping during driving maneuvers aggressive to reduce the speed of inclination and the speed of the vehicle for a more secure feeling.
Cadillac SRX also offers an all-wheel-drive system incorporates an electronic limited slip differential (eLSD) back. Not only improves traction in slippery conditions, but provides side-to-side torque transfer along the rear axle to improve turning control difficult. It 'was developed in collaboration with Haldex, the leader in four-wheel drive and eLSD technology enables the AWD system to distribute torque front to the rear axle, and also from side to side on the rear axle, sending power to the wheel with more traction.
