The moment many of us have been waiting for has finally arrived; the Duramax diesel powered Chevy Colorado will be available for 2016. The recently redesigned Chevrolet Colorado now adds a 2.8L Duramax turbo-diesel to its powertrain options, giving buyers the choice of the new diesel, the 2.5L four-cylinder, and a 3.6L V-6.
The 2016 Duramax diesel powered Chevy Colorado will have 369 lb-ft of torque at 2,000 RPM and 181 horsepower at 3,400 RPM, giving this midsize truck a maximum towing capacity of 7,700 pounds for 2WD models. While official MPG ratings haven’t been announced, GM is projecting it to top the mid-size truck segment with best in class economy. The diesel will be available on the LT and Z71 Crew Cab models, in either 2WD or 4WD, with a $3,730 option price tag over the comparable 3.6L V-6 model.
We knew a diesel Colorado was coming when we tested one on our Truck Of The Year test, and Assistant Chief Engineer Scott Yackley confirmed that when he said “A diesel engine was part of the Colorado’s portfolio plan from the very beginning, meaning the chassis, suspension and other elements of its architecture were engineered to support its capability.” What we didn’t know were the features that General Motors’ cleanest diesel truck and engine would have including:
-Smart diesel exhaust brake system that enhances vehicle control and reduces brake wear on steep grades
-Standard Hydra-Matic 6L50 six-speed automatic transmission matched with a Centrifugal Pendulum Vibration Absorber (CPVA) in the torque converter
-A Z82 trailering package is standard and includes a hitch receiver and seven-pin connector
-An all-new integrated trailer brake controller is standard and exclusive on diesel models
-The G80 automatic locking rear differential and 3.42 rear axle ratio will be standard
-A new, electronically controlled two-speed transfer case is included on 4WD models
The four-cylinder 2.8L Duramax engine features technology that you would see on the V-8 diesel that many late-model diesel owners would be familiar with, including a variable-geometry turbocharger, common rail direct fuel injection, and B20 bio-diesel capability. With ever increasing emission restrictions on diesel engines, GM is using a cooled EGR system, which diverts some of the engine-out exhaust back into the intake that lowers combustion temperatures and reduces NOx.
Wanting to offer consumers a quiet and comfortable ride, engineers integrated a Centrifugal Pendulum Vibration Absorber (CVPA) in the torque converter of the Hydra-Matic 6L50 six-speed transmission. The CPVA is an absorbing damper that uses a second set of springs to cancel out the engine’s torsional vibrations, leaving the passenger compartment vibration free.
Making it a comfortable and easy to drive truck is helped by having a driver-selectable exhaust brake system that uses engine compression to improve vehicle control and reduce brake-pad wear. When the exhaust brake is engaged in cruise mode, the vehicle speed is maintained when traveling downhill without having to apply the brakes and exit cruise control. When in non-cruise mode, the exhaust brake will assist in braking regardless of load and grade.
After driving the V-6 2015 Chevy Colorado we can’t wait to get our hands on the new Duramax powered truck and test it towing, on the trails, and daily driving. The 2016 Duramax Colorado is expected to go on sale in the fall of 2015.
