LOUISVILLE, KY – General Motors announced the availability of the 6.6L Duramax turbo-diesel engine for the 12,300-lb. Class-C chassis. In addition to the 14,050-lb. chassis, General Motors has also announced that it will co-brand its 12,300-lb. and 9,600-lb. GVWR chassis with Workhouse Custom Chassis. All three chassis come standard with the Vortec 6.0 V-8 engine. “We believe our chassis for the Chevy Express van delivers exactly what motor home customers want from their RV – exceptional capability, durability and power, with the comfort and convenience they’ve come to appreciate from GM vehicles,” said Ross Hendrix, General Motors market-ing director of vans and trucks. With the Chevrolet/Workhorse Class-C Chassis, an independent short/long-arm (SLA) front suspension provides both ride quality and long-term durability. The chassis’ sharp turning radius allows the driver to maneuver in and out of tight spots with ease, adding to driver comfort. Inside, the chassis delivers more legroom and interior space for the driver and passenger, including larger step pads and wider footwells. There’s also more functional storage, including deep and wide door storage pockets. The Chevrolet/Workhorse Class-C 12,300 chassis can now be powered by a Duramax turbo-diesel engine that delivers a class-leading 250-hp and 460-lbs-ft. torque run through a 4L85-E heavy-duty four-speed transmission. All three chassis – the 14,050, the 12,300-lb. and the 9,600-lb. – are matched to the four-speed elec-tronically controlled automatic transmissions with a 300-hp Vortec 6.0L V-8 engine. Braking performance is provided by the standard four-wheel disc anti-lock brake system with Dy-namic Rear Proportioning (DRP). DRP adjusts brake pressure toward the front or rear of the vehicle; therefore, optimizing front and rear-brake performance under varying loads and road surfaces. General Motors builds all of the Class-C chassis at its Wentzville Assembly Center in Missouri. Production is expected to begin in January 2006.
