2017 GM midsize trucks get new V-6 engine, transmission

General Motors Co. is adding a new 3.6-liter V-6 engine and eight-speed automatic transmission to its 2017 Chevrolet Colorado and GMC Canyon midsize pickups, replacing an older V-6 engine that came with a six-speed transmission.

The new powertrain slightly increases horsepower and torque, while GM says the replacement engine and eight-speed transmission will aid acceleration and shifting. The engine also for the first time includes cylinder deactivation, disabling two cylinders when they are not needed to save fuel.

GM re-introduced the Colorado and Canyon in fall 2014 as new 2015 models. The Colorado is on track to sell 160,000 units in its first two years on the market. Through July this year, Colorado sales have totaled 60,422, up nearly 24 percent year-over-year. Canyon sales have totaled 20,894, up more than 18 percent from the same seven months in 2015.

A top Canyon Denali model is new for the 2017 model year and includes a special chrome grille, 20-inch aluminum wheels with painted accents, tubular chrome assist steps and other Denali specific interior and exterior features. GMC also is adding a new off-road All Terrain X, which adds to its All Terrain model with Goodyear DuraTrac all-terrain tires, all-weather floor liners and other features.

The 2017 model Colorado and Canyon will be available in the fourth quarter. Pricing for 2017 models has not been announced.
