General Motors is preparing for the imminent encroachment of the new-and-improved GMC Canyon and Chevrolet Colorado midsize trucks on American soil after a couple model years’ absence. Therefore, let the bench racing begin: GM says the Canyon and Colorado will be the most-powerful pickup trucks in the midsize class.

A press release from GM said the standard 2.5-liter four-cylinder gasoline engine will be rated at 200 horsepower and 191 ft-lbs of torque, while the 3.6-liter V6 engine will be rated at 306 horsepower and 269 ft-lbs of torque. Either should be plenty to power a midsize truck. The release said both engines feature direct injection and variable valve timing to make the most of power and efficiency thanks to dual-overhead camshafts with variable valve timing, direct injection, and jet-spray piston cooling. Aluminum engine blocks and forged-steel crankshafts ensure a long lifecycle, the release added.

We’ve experienced the 3.6-liter V6 in a number of applications, including the Chevrolet Equinox, GMC Acadia, and Buick Enclave. Those are all front-wheel drive-based vehicles that mount the engine sideways. The GM press release said the Colorado and Canyon will make use of the same engine, but it will be optimized for rear-wheel drive, midsize truck duty.

Both engines are based on proven engine designs found throughout the General Motors’ family, but are optimized for the demands of truck use with the latest technology for improving performance and efficiency. This includes torque at lower RPMs for better towing power and a more confident feeling while pulling a trailer.

Both engines are matched to a six-speed automatic transmission; a six-speed manual is available on select extended cab 2WD models. The six-speed automatic is tuned specifically for the truck engines, offering features like auto grade braking and tow/haul mode.

GM Midsize Trucks Chief Vehicle Engineer Anita Burke said, “Every decision we made considered the wants and needs of midsize truck customers. The 2015 Chevrolet Colorado and GMC Canyon are engineered to deliver class leading horsepower. Not everyone needs the size or the capability of a full-sized pickup. Now customers have a viable option in a smaller package.”

Add me to that list of people who don’t need the capabilities of a full-sized pickup.
