As extensively covered by GM Authority, 2023 Chevy Colorado and 2023 GMC Canyon units didn’t start shipping to dealers until February 28th, 2023 because General Motors was waiting on the U.S. Environmental Protection Agency (EPA) to release fuel economy ratings for the all-new midsizers. Then, we finally got fuel efficiency figures, but only for the base turbocharged 2.7L I4 L2R gasoline engine. Now, GM Authority has exclusively learned the fuel economy ratings for 2023 Colorado units equipped with 4WD and the turbocharged 2.7L I4 L3B gasoline engine.
The EPA’s city/highway/combined fuel economy ratings for the 2023 Chevy Colorado equipped with 4WD and the L3B engine are 17/21/19 mpg.

It’s worth noting that the table above doesn’t include 2WD units equipped with the L3B, as those ratings have yet to be released. Additionally, now that these fuel economy ratings have been released, all 2023 Colorado 4WD units can now be shipped.
As a reminder, the 2023 Chevy Colorado is available with three output levels across two engine choices. The base turbocharged 2.7L I4 L2R is rated at 237 horsepower and 260 pound-feet of torque. Meanwhile, the 2.7L I4 L3B is available in Turbo Plus and Turbo High-Output configurations, where the engine makes 310 horsepower and 391 pound-feet of torque or 310 horsepower and 430 pound-feet of torque, respectively.
In regard to transmission options, all units are equipped with the revised GM eight-speed automatic transmission.
Under the body panels, the 2023 Chevy Colorado, as well as the 2023 GMC Canyon, rides on the updated 31XX-2 platform, while production is currently under way at the GM Wentzville plant in Missouri.
