SYMMETRICAL ALLWHEEL DRIVE
Continuous All-Wheel Drive
Models equipped with 6-speed manual transmissions utilize a viscous-type locking center differential with torque distribution normally configured at a
50/50-split front-to-rear. If wheel speed differs between front and rear axles, the system helps distribute power to the wheels with the most traction. 3.6R
models equipped with a viscous-type limited-slip rear differential.
Active All-Wheel Drive
Models equipped with Lineartronic™ CVT utilize an electronically controlled variable transfer clutch to distribute power to where traction is needed.
Sensors monitor parameters such as wheel slippage, throttle position and braking, to help determine torque distribution and direct it to the wheels
with optimum traction.
Variable Torque Distribution (VTD)
All-Wheel Drive
Models equipped with 5-speed automatic transmission utilize an electronically controlled variable transfer clutch in conjunction with a planetary-type
center differential and a viscous-type limited-slip rear differential. Torque distribution is normally configured at a performance-oriented rear-wheel-bi-
ased 45/55-split front-to-rear. Sensors monitor parameters such as wheel slippage, throttle position and braking to help determine torque distribution
and direct it to the wheels with optimum traction.
STABILITY AND TRACTION
Vehicle Dynamics Control (VDC)
VDC electronic stability control utilizes sensors which constantly monitor wheel speeds, steering angle, brake pressure, vehicle yaw rate and
lateral g-forces. If VDC detects a difference between the drivers intended path and the one the vehicle is actually taking, VDC applies braking
power and/or reduces engine torque to help correct vehicle path. Standard on all models
Traction Control System (TCS)
VDC also incorporates an all-wheel, all-speed traction control system which senses a loss of traction and applies braking force to the slipping
wheel or wheels as necessary to maintain vehicle motion.
CHASSIS
Steering
Rack-and-pinion with engine-speed controlled variable power assist
Suspension
