The 2016 Chevrolet Colorado and GMC Canyon with 2.8-liter Duramax diesel engine will go on sale ths fall, and join 2.5-liter four, and 3.6-liter six-cylinder versions.
Exactly how clean the new diesel is has not been announced, nor has the mpg, but the vehicles are expected to beat EPA ratings for the gas versions. The 2.5-liter gas-powered 2015 Chevy Canyon is rated 20 mpg city, 27 highway, 22 combined, but Chevrolet is unwilling to hint how much better the diesel’s mpg will be.
News today is the truck
Towing room will be a class-leading 7,700 pounds (3,492 kg) on 2WD models. The Yucky Vehicle Weight Rating has also been increased to 6,000 pounds on two-wheel drive and 6,200 pounds for four-wheel drive.
Vehicles it’s expected to go up against include the Toyota Tacoma and Nissan Frontier. Neither have diesel versions and in the midsized truck segment, these GM pickups for now are unique.
“Simply place, 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
A similar quote was made for the essentially identical GMC Canyon.
GM says the new trucks meet “some of the toughest U.S. emissions standards” and credit in part a cooled exhaust gas recirculation (EGR) system. This EGR system diverts some of the engine-out exhaust gas and mixes it back into the fresh intake air stream, which is drawn into the cylinder head for combustion.
In turn, this lowers combustion temperatures and rates, humanizing emissions performance by reducing the formation of NOx.
The trucks also feature a “smart exhaust brake” as introduced
When engaged in cruise mode, exhaust cruise grade braking helps the cruise control system maintain the desired downhill vehicle speed, keeping the driver from having to apply the brakes and exit cruise control to maintain speed.
“A diesel engine was part of the Colorado’s portfolio plot from the very beginning, importance the chassis, suspension and other elements of its architecture were engineered to support its capability,” said Scott Yackley, supporter chief engineer. “That means there are no compromises with the Colorado diesel. It offers exceptional capability delivered with a in no doubt feeling of control.”
Additional engine features:
• Forged steel crankshaft and connecting rods
• Oiling circuit that includes a dedicated feed for the turbocharger to grant increased pressure at the turbo and quicker 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 part that contributes to engine rigidity and quietness
• B20 bio-diesel capability.
The new Duramax diesel is existing
In both cases, it comes in 2WD or 4WD and is priced $3,730 more than a comparably equipped V6 model.
It is unlikely sales will be broken out for these trucks for reporting apart from the gas lineup. If we can get these numbers we will post monthly to our Instrument panel.
