Chevy simplified the Colorado engine lineup. It is getting one engine, the “”2.7-liter Turbo,”” which Chevy won’t say is a four-cylinder. It comes in a base version (237 horsepower, 259 lb-ft), a Turbo Plus version (310 hp, 390 lb-ft) and a High Output version for the ZR2 (310 hp and 430 lb-ft). That engine pairs with what Chevy calls the “”second-generation”” eight-speed automatic transmission, which has been retuned for better performance and downshifting. With GM aiming to go zero-emission by 2035, this may be Chevy’s last combustion-powered Colorado. Off-roading is a key appeal for mid-size trucks. The Colorado is a 2023 model year vehicle, and Chevy says production will begin in the first half of 2023. No word yet on pricing.
