Car and Driver reports that General Motors President Mark Reuss still won't confirm a GMC spinoff, but he does add that if a "Professional Grade" version of the Colorado is built, it will be very different than its Bowtie-wearing counterpart. As the current Canyon is essentially a badge-swap away from being a Chevy, the idea of increased differentiation strikes us as a welcome development. We aren't exactly sure how much different the would-be pickup might be, but we're guessing that Reuss is referring to more unique parts than than the front fascia and minor trim enhancements that differentiate the GMC Sierra from the Silverado.
Reuss also tells C/D that the new Colorado is surprisingly large – about 90-95 percent of the size of the Silverado, and he notes the truck will feature different powertrains. We assumed that the Colorado will feature different powertrains, and we hope that a fuel-efficient six-cylinder and a diesel offering will be available under the hood.
