GM will drop the 2.8L I-4 LWN Duramax turbodiesel engine from the Chevy Colorado lineup at the conclusion of the 2022 model year, with the next-generation version of the mid-size pickup set to offer only one engine choice: the turbocharged 2.7L I-4 L3B gasoline engine.
GM Authority has now learned when GM will build the last diesel-powered 2022 Chevy Colorado at its Wentzville Assembly plant in Missouri. According to our sources, the last scheduled week of production for the diesel version of the pickup will begin on July 4th. Once the week is over, GM will cease production of the LWN-powered Chevy Colorado models, however gasoline versions of the truck will remain in production for a brief period before the automaker shifts to 2023 Colorado production, as GM Authority reported previously.
The next-generation 2023 Chevy Colorado will have only one engine option: the turbocharged 2.7L I4 L3B. In the Chevy Silverado 1500, this engine is rated at 310 horsepower and an uprated 430 pound-feet of torque and pairs to a GM 10-speed automatic transmission. This is a sizable upgrade over the LWN diesel engine, which is rated at 181 horsepower and 369 pound-feet of torque and connects to a somewhat outdated six-speed automatic transmission. These same powertrain changes will also apply to the next-generation 2023 GMC Canyon, which will continue to be produced alongside the Colorado in Wentzville.
The next-generation Chevy Colorado will ride on a heavily revised version of the current model’s 31XX platform and will also adopt the GM Global B electrical architecture, enabling over-the-air updates and other current tech features. The 2023 Colorado, along with the new 2023 GMC Canyon, is expected to make its debut sometime in the first six months of this year – meaning these two trucks’ official debut is imminent.
We’ll have all the official details on the 2023 Chevy Colorado once they become available. For now, be sure to subscribe to GM Authority for more Chevy Colorado news, Chevy news, General Motors production news and around-the-clock GM news coverage.
