Tough competition makes everybody better. GM is pushing forward with significant powertrain updates for the 2017 Chevy Colorado. The midsize truck gets a new 3.6L V6 gasoline engine that is mated to a GM-developed Hydra-Matic 8L45 8-speed automatic transmission.
Chevrolet targeted performance and refinement with the engine/transmission combination. The new V6 represents a slight bump in power output. It’s rated at 308 hp @ 6,800 rpm and 275 lb-ft of torque @ 4,000 rpm. The engine also features cylinder deactivation (Active Fuel Management) system which allows the truck to run in V4 mode under light load conditions. The outgoing V6 made 305 hp and 269 lb-ft of torque.
The 8-speed automatic provides a wider gear ratio spread than the 6-speed, and this should allow for a quicker off-the-line getaway and more efficient steady speed cruising on the highway. The 8-speed is about the same size and weight as the 6-speed, according to GM.
Chevrolet did not yet specify any changes to the EPA fuel economy ratings or maximum payload/towing capability. While the real-world performance may improve, the overall ratings may not change.We cannot wait to test the new power package on our 100-mile MPG loop with the test trailer and on the extreme Ike Gauntlet towing challenge.
