GM unveiled the 2023 Chevy Colorado late in July, revealing an all-new third generation for the pickup. Among the many updates and changes is a fresh platform – the question is, what exactly is fresh about it?
For those readers who may be unaware, the 2023 Chevy Colorado rides on an architecture known internally at GM as 31XX-2, which is essentially a modified version of the 31XX platform that underpinned the previous generation. We spoke with Chevy directly for more information on what makes the 31XX-2 platform different from the preceding 31XX platform, and according to Colorado Chief Engineer Nick Katcherian, there are both similarities and differences worth pointing out.
In an interview with GM Authority, Katcherian was asked if portions of the 31XX-2 platform were taken from the 31XX platform, to which Katcherian responded that while the frame design was similar, the “whole entire front end is new,” while “chunks of the back end are new” as well. However, Katcherian also said that parts of the middle section of the frame are shared between 31XX-2 and 31XX in terms of overall design.
“All new, with a similar design,” Katcherian told GM Authority.
Notably, the 2023 Chevy Colorado also runs an updated version of the GM eight-speed automatic transmission equipped by the second-gen model. As GM Authority has covered in the past, the pre-update eight-speed was the subject of multiple lawsuits and reliability issues. Now, however, the updated eight-speed incorporates “learnings” taken from the previous generation and adds improvements and more componentry.
As for the engine spec, the 2023 Chevy Colorado is powered exclusively by the turbocharged 2.7L I4 L3B gasoline engine, which is offered in three levels of tune, depending on the trim level selected. The base tune is known as the 2.7 I4 Turbo, which is rated at 237 horsepower and 259 pound-feet of torque and includes its own RPO code (L2R). The other two tunes are the mid-range 2.7L Turbo Plus, which is rated at 310 horsepower and 390 pound-feet of torque, and the 2.7L Turbo High-Output, which is rated at 310 horsepower and 430 pound-feet of torque.
Production of the 2023 Chevy Colorado will launch in January of 2023 at the GM Wentzville plant in Missouri.
