The new Colorado is "about 6 inches narrower, 18 inches shorter, 3 inches lower and 1,000 pounds lighter" than the Silverado full size pickup, according to Pickuptrucks.com. The hydroformed frame is fully boxed. Pickuptrucks.com expects the payload rating to be about 1400 lb, pretty low considering the world truck has payload of about 2200 lb. It's worth noting that almost no parts are shared between the world Colorado and the built-in-Missouri version.
The Colorado for USA will be available in two cab configurations (extended cab and crew cab) and two bed lengths (5 ft or 6 ft). For the 2015 model year, powerplant options will be limited to a 2.5L four cylinder gasoline engine (193 hp, 184 ft lb of torque) and a 3.6L gas V6 (302 hp, 270 ft lb). Both engines will be backed by a 6 speed automatic.
Coming in the 2016 model year is a 2.8L four cylinder turbodiesel, designed by VM Motori. Pickuptrucks.com expects about 350 ft lb of torque. The diesel will be available in all trim levels, including the utilitarian Work Truck (W/T). (Does this mean that GM expects VW to bring their diesel engine pickup, the Amarok, to USA in 2016?)
No fuel economy estimates for any of the above engines has been made available.
Suspension is independent with coil springs in front, solid axle with leaf springs in the rear. Disc brakes all around. An Eaton G80 automatic locking rear differential is optional.
