General Motors Active Rear Steering Technology
Active Rear Steering is a General Motors chassis technology that turns the rear wheels of a vehicle, delivering greater low-speed agility and high-speed stability.
How It Works
- At low speeds, Active Rear Steering provides a tight turning radius and excellent maneuverability by turning the rear wheels in the opposite direction from the front wheels. This results in fast cornering response and easy turns into tight parking spaces.
- At higher speeds, Active Rear Steering turns the rear wheels in the same direction as the front wheels, delivering smooth lane change and overall stability.
The biggest benefit of Active Rear Steering can be seen in parking situations, as it enables the Cadillac CT6 sedan to have a turning circle of only 11.4 meters, which is comparable to that of the Cadillac CTS. That is quite impressive given that the CT6 has a 3,109 mm (122.4 inches) wheelbase, while the CTS has a much shorter wheelbase of 2,910.84 mm (114.6 inches).
From 2002 to 2005, Active Rear Steering was available on some GM pickup trucks and SUVs as Quadrasteer. An all-new iteration of the feature is available on the Cadillac CT6 as part of the Active Chassis Package.
