All that translates to 220 horsepower at 5600 rpm and 225 lb-ft of torque at 2800 rpm. The Vortec 3500 sustains that torque level over 90 percent of its rev range, good when hauling of heavy loads or towing trailers. Recommended fuel is 87 octane regular, making the Colorado cheaper to keep.
Max towing for the Colorado with the five-cylinder engine and automatic transmission is 4000 pounds, 2000 less than the old S10. Chevrolet was willing to trade capability that few used in a midsized truck for a more comfortable ride, important for those who frequently use their trucks for general passenger hauling.
Driving a rear-drive Colorado with the Vortec 3500 proves that Chevy made the right decisions. With foot to the floor, an unladen Colorado zips up to traffic speed, the Hydra-Matic 4L60-E four-speed automatic clipping off shifts smoothly enough to be unremarkable. On loose gravel, whether on a dirt road or just off the pavement, if given too much power, the traction control system reduces power completely and the Colorado falls on its face. That's not important except when trying to merge into fast-moving traffic from a pebbly roadside. The traction control override button, located high on the dash, can be used in such a situation. In snow, however, the traction control should help in taming a pickup's lightly loaded rear end.
By sacrificing some towing capacity, GM engineers were able to reduce the rear spring weight and otherwise tune the suspension for a smooth ride, and that's really evident in the Colorado. On a washboard dirt road the rear end isn't bouncing around like a Polynesian hula dancer's grass skirt. It's the front end that feels firmer. It still rides like a truck, but it isn't nasty about it.
The front disc/rear drum brakes are big and meaty and certainly should be enough for any load the Colorado is allowed to carry. Suspension was firm enough to handle hard stops on pavement without drama. The ABS does its job neatly, keeping the truck in line even when slamming on the brakes on a gravelly road. Next Page
