GMC has introduced GMC C7500 Pro-Rollback concept vehicle aimed to help stranded vehicles and passengers.It features the C7500 Pro-Rollback’s Duramax 7800 diesel engine. The OHC, 6-cylinder power-plant produces 275 horsepower at 2400 rpm and 800 lb-ft of torque at 1450 rpm. And with a 25,950-pound gross vehicle weight rating (GVWR), Pro-Rollback can transport nearly anything. Power is transferred to the trapezoidal design, 22.5-inch Alcoa aluminum wheels via an Allison 3000 Series 6-speed automatic transmission. A 100-gallon fuel tank provides a projected 900-mile driving range. The Gearworks etrace mobile work management application helps assists the driver in getting to the most remote places quickly, efficiently and safely. Dispatched from a PC with Internet access and running on the vehicle’s wireless, Palm-powered 1733 PDA from Symbol Technologies, towers and their dispatchers have GPS-based, real-time tracking and messaging – as well as electronic work orders, driving directions to the site, electronic signature capture, credit card and receipt printing, and bar code reading of Vehicle Identification Numbers. Pro-Rollback also features Night Vision, which helps the driver to locate stranded vehicles during low-light situations. For emergency roadside assistance, Pro-Rollback is equipped with a fire extinguisher, a vehicle emergency kit and a first-aid kit, which are under development by General Motors Service Parts Operations (SPO). The C7500 Pro-Rollback also features a 21-foot aluminum Rollback platform with integrated storage areas. The cab and body are finished in a Dynamite Orange triple-coat paint with brushed aluminum accents. The C7500 Pro-Rollback’s four-door crew cab – derived from GMC’s all-new 2003 model-year series of medium-duty trucks – accommodates four passengers and has leather seats. The driver and front-passenger seats are equipped with an air suspension system, while the rear seats feature a fold-down center portion that acts as an armrest and features integrated cupholders. A full-width rear console is equipped with a built-in audio, game-play capability, and DVD system. The drop-down screen folds into the headliner when not in use. The rear console also holds magazines and other reading materials.
