Say goodbye to the Duramax.
General Motors currently offers two mid-size trucks, the 2021 Chevrolet Colorado and the mechanically identical GMC Canyon (though the Colorado is available with ZR2 and ZR2 Bison off-road performance models). Both trucks have been on the market since 2015 and have received a minor update for 2021, and GM has already invested $1.5 billion to build its next-generation mid-size trucks. Which brings us to the latest developments.
According to a report from Muscle Cars & Trucks, the next-generation of Colorado and Canyon are expected to arrive in 2023, and the engine lineup will be radically different. If this report is accurate, the Colorado and Canyon will go from three engines down to one.
Currently, the GM twins are available with three engines, starting with a 2.5-liter four-cylinder, an optional 3.6-liter V6, and a 2.8-liter Duramax turbo-diesel putting out 200, 308, and 188 horsepower respectively. The diesel compensates its low hp rating with a healthy 369 pound-feet of torque and superior fuel economy numbers. Even though it wasn't quick, the Duramax did provide excellent EPA estimated figures of 19-mpg in the city and 28-mpg on the highway.
And it could be time to say goodbye to the only compression ignition engine in America's midsize truck segment.
The little Duramax, along with the two atmospheric gasoline engines, will give way to a 2.7-liter turbocharged four-cylinder mated to a 10-speed automatic transmission. It's reported that this will be the only engine available on the next-generation Colorado and Canyon.
In other words, if you want a Colorado or Canyon with the Duramax diesel engine, your time is running out to buy one. Corroborating with the original report is that GM sold the manufacturing plant in Thailand where the engine is built to China's Great Wall Motors in February. The engine is otherwise currently available in GM's ancient Chevrolet Express and GMC Savana full-sized vans.
The 2.7-liter turbocharged four cylinder engine is currently used in the full-size Chevrolet Silverado 1500 and GMC Sierra 1500 where it produces 310 hp and 348 lb-ft of torque. It's also in the Cadillac CT4-V, where it produces 325 hp and 381 lb-ft of torque. Compared to the Ford Ranger, which currently offers just one engine with a 2.3L EcoBoost that's shared with the Ford Mustang, the next-generation Chevrolet Colorado and GMC Canyon could have the Ford beat by some 40 horsepower and 38 lb-ft of torque, based on the full-size truck numbers.
Indeed, the next battle in the midsize truck war appears to be on the horizon.
