Chassis and suspension
The Cadillac SRX has a four-wheel independent suspension system and a standard rack-and-pinion hydraulic steering system - and offers a variable-effort, speed-sensitive steering system - with tuning biased for sport sedan-style driving and strong on-center feel. StabiliTrak electronic stability control is standard and works with the standard four-wheel-disc/four-channel-ABS braking system.
The core elements of the chassis and suspension systems include:
An independent MacPherson strut suspension system is standard on all models,
featuring a direct-acting stabilizer bar and hydraulic ride bushings.
An independent "H-arm" rear suspension incorporates a lightweight hollow
aluminum lower control arm and a hollow stabilizer bar.
Power-assisted rack-and-pinion steering is standard on Base and the Luxury
Collections.
Power-assisted variable-effort and speed-sensitive rack-and-pinion steering
system is standard on the Performance and Premium Collections.
A rear axle ratio of 3.39 is standard on all models.
A trailering package is available on the Luxury, Performance and Premium
Collections and increases the towing capacity to 3,500 pounds (1,587 kg).
For 2012, the Base suspension offers greater ride quality that maintains excellent handling characteristics, thanks to new upper front strut mounts, improved shock valve tuning, new bonded bushings for the front stabilizer bar and new twin-tube rear shocks that provide greater road isolation.
The Sport active suspension - standard on Performance and Premium Collections - is also improved for 2012, with new front upper strut mounts, new shock valving, bonded stabilizer bar bushings and revised calibrations for this continuously variable real-time damping suspension system. Electronically controlled dampers at each corner "read" the road constantly to make real-time adjustments within milliseconds. They deliver the just-right damper rate for all road conditions, for greater comfort and a greater feeling of control. This system also increases damping during aggressive handling maneuvers to reduce the roll velocity and pitch velocity of the vehicle for a more confident feel.
Cadillac SRX is also offered with an all-wheel-drive system that incorporates an electronic limited-slip (eLSD) rear differential. It not only improves traction in slippery road conditions, but it provides side-to-side torque transfer along the rear axle to enhance control during hard cornering. It was developed in partnership with Haldex, a leader in all-wheel-drive technology and the eLSD enables the AWD system to distribute torque from the front to rear axle, and also side-to-side, across the rear axle, sending power to the wheel with the greatest traction.
