The GM 3500 HD is a new class 4 truck being introduced this fall. Complementing GM's successful introduction of the 11,000 lb and 12,000 lb cab/chassis in 1990, this truck will have a GVW rating of up to 15,000 lbs.
The design and development of this truck began in late 1987 and utilized selected common parts from GM's light duty pickup truck and commercial forward control chassis.
Several features unique to the class 4 market were incorporated for increased customer satisfaction. Among these are low loading heights, three cab/axle offerings, large brakes, increased cooling, and large frame sections with straight flat rails behind the cab.
A description of the vehicle features and how the design evolved and developed will be detailed. In addition, significant performance criteria that were met or exceeded will be summarized to establish the high level of vehicle performance achieved.
