2015 Chevrolet Colorado and GMC Canyon are going on sale this fall. As soon as they go on sale they will be the most powerful vehicles in the midsized truck segment. The Colorado and Canyon’s available engines are the 2.5L I-4, which has been rated at 200 horsepower (147 kW) and 259 Nm (191 lb-ft) of torque, and the 3.6L V-6, rated at 305 horsepower (224 kW) and 365 Nm (269 lb-ft) of torque. Both vehicles will also provide great trailering capabilities, with the capacity to tow up to 7,000 pounds. Each engine includes direct injection and variable valve timing. Both powerplants are optimized for the demands of truck use with the latest technology for improving performance and efficiency. Precisely, this includes torque at lower RPMs for better towing and a more confident feeling while pulling a trailer. Furthermore, both units are coupled with a six-speed automatic transmission as a standard. It is tuned specifically for the truck engines, offering features such as auto grade braking and tow/haul mode. As an option, there is available the six-speed manual on select extended cab 2WD models. The great amount of horsepower also comes with efficiency, due to the added dual-overhead camshafts with variable valve timing, direct injection, and jet-spray piston cooling. At the same time the aluminum blocks and forged-steel crankshafts ensure a long-life cycle.    Source: Chevrolet
