The Class 4-5 C4500/C5500 Series includes regular, crew and chassis cabs. They also offer six niche-vocation packages for ambulance, fire and rescue, school and shuttle bus, snowplow and wrecker applications. GVWRs range from 16,000-19,500 pounds, and horsepower ranges from 210-300 (Duramax 6600 diesel) and 225-325 (Vortec 8100 gas). Transmission choices are a Synchronized ZF 6-speed manual and an electronically controlled Allison 1000 5-speed automatic.

The Class 6-8 C6500, C7500 and C8500 series trucks will be initially available in two-wheel-drive regular cab, crew and chassis cab configurations. GVWRs range from 19,501 to 61,000 pounds, with horsepower ratings from 200-275 (Duramax 7800 diesel), 190-300 (Caterpillar 3126E diesel) and 225-295 (Vortec 8100 gas).
