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.
