When we drove the Chevrolet Colorado at the media preview last year, what we heard from everybody we talked to was “Where’s the diesel? Will it have a diesel? Would be better with a diesel. I’d buy one if it had a diesel.” Well, now is the time to put your money where your mouth is and buy one. Chevrolet released the Colorado with a Duramax diesel yesterday.
Chevy notes that the Colorado’s Duramax diesel will offer 369 lb-ft of torque out of 2.8 liters, good enough to boost towing capacity to 7,700 pounds on 2WD models.
“Simply put, there’s no other midsize truck that can do what Colorado can with its all-new Duramax diesel,” said Sandor Piszar, director of Chevrolet Truck Marketing. “Along with greater capability and efficiency, it expands the Colorado lineup to give customers more choices and the capability of exploring more possibilities on and off the road.”
The Colorado with the Duramax diesel goes on sale this fall, and will be offered on the LT and Z71 Crew Cab models, with 2WD or 4WD. It carries a $3,730 price tag, compared to a comparably equipped 3.6L V-6 model.
Colorado diesel models also receive the following exclusive features:
- 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, which reduces powertrain noise and vibration
- The 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 is standard
- A 3.42 rear axle ratio is standard
- A new, electronically controlled two-speed transfer case is included on 4WD models
- Maximum trailering rating of 7,700 pounds (3,492 kg) for 2WD models and 7,600 pounds (3,447 kg) for 4WD
- GVWRs of 6,000 pounds (2,721 kg) for 2WD and 6,200 pounds (2,812 kg) for 4WD.
“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,” said Scott Yackley, assistant chief engineer. “That means there are no compromises with the Colorado diesel. It offers exceptional capability delivered with a confident feeling of control.”
The 2.8L Duramax is a stout engine featuring:
- Iron cylinder block and aluminum DOHC cylinder head
- Forged steel crankshaft and connecting rods
- Oiling circuit that includes a dedicated feed for the turbocharger to provide increased pressure at the turbo and faster oil delivery
- Piston-cooling oil jets
- 16.5:1 compression ratio
- Common rail direct injection fuel system
- Ceramic glow plugs for shorter heat-up times and higher glow temperatures
- Balance shaft that contributes to smoothness and drives the oil pump
- Laminated steel oil pan with upper aluminum section that contributes to engine rigidity and quietness
- B20 bio-diesel capability.
Its cooled exhaust gas recirculation system contributes to lower emissions by diverting some of the exhaust gas and mixing it back into the fresh intake air stream and back into the cylinder head.
The engine also features an integrated, driver-selectable exhaust brake system, similar to that on the 2015 Silverado HD. It uses the compression power of the 2.8L Duramax engine to improve vehicle control and reduce brake pad wear. With cruise control engaged, the system helps to maintain speed when descending a hill, keeping the driver’s foot off the brakes to maintain speed.
When cruise control isn’t engaged, the transmission and the exhaust brake deliver the correct amount of braking to assist in vehicle control, regardless of vehicle load. It is a smart system that varies the amount of brakes needed for the vehicle, load and grade.
Chevrolet sold 41,575 Colorado trucks in the first six months of 2015.
