Troy, Michigan - The Quadrasteer four-wheel steering system, which debuted on the top-of-the-line GMC Sierra Denali full size pickup, will now be available on the 2002 GMC Sierra and Chevy Silverado 1/2 ton, extended cab short box trucks.

In addition, 2003 models with optional Quadrasteer will include the Chevrolet Silverado and GMC Sierra 1500HD short box crew cabs and Chevrolet Suburban and GMC Yukon XL 3/4 ton full-size sport utility vehicles.

Quadrasteer was developed by GM supplier, Delphi Automotive Systems. "We are very pleased to see Quadrasteer available across more vehicle platforms at General Motors," stated Paul J. Tosch, president of Delphi Saginaw Steering Systems and vice president of Delphi Automotive Systems. "Full size SUVs are the next logical step for vehicles which will benefit from this revolutionary system. Quadrasteer willl enhance their consumer value through the added maneuverability and stability as seen now on the Sierra Denali."

GMC is also featuring Quadrasteer by Delphi on their new concept truck, Terra4, which debuted at the Chicago Auto Show last week. The Terra4 is a four-door, four-wheel drive, four-wheel steer utility truck with four doors and four ways to access the cargo bay. It is intended to meet the needs of a truck market that has shifted away from traditional utility, work use to personal use.

Quadrasteer combines conventional front-wheel steering with an electrically powered rear-wheel steering system. At lower speeds, the rear wheels turn in the opposite direction of the front wheels. At moderate speeds, the rear wheels remain straight or neutral. At higher speeds, the rear wheels turn in the same direction as the front wheels.

QUADRASTEER improves high-speed stability, particularly when pulling a trailer, and makes low-speed maneuvering easier.
