What engine comes in the Chevy Colorado?
The current Chevy Colorado is powered by a 2.7-liter turbocharged inline-4 engine, delivering about 310 horsepower and 430 lb-ft of torque, paired with an eight-speed automatic transmission.
The modern Colorado lineup revolves around a single gasoline powertrain designed to blend work capability with everyday practicality. The 2.7L turbocharged engine is part of GM’s Ecotec family and uses direct injection, variable valve timing, and a twin-scroll turbo to deliver strong mid-range torque and high-end power without sacrificing efficiency.
Key details about the current engine option are listed below.
- Engine: 2.7-liter turbocharged inline-4 (Ecotec)
- Displacement: 2.7 L
- Horsepower: about 310 hp
- Torque: about 430 lb-ft
- Turbocharger: Twin-scroll turbocharger
- Induction: Direct injection
- Configuration: Inline-4
- Transmission: 8-speed automatic
- Drivetrain options: 4x4 available; 2WD also offered on certain trims
Note: Power figures can vary slightly by model year and trim level, but 310 hp and 430 lb-ft are standard for the current generation’s 2.7L turbo engine in most configurations.
Chevrolet pairs the 2.7L turbo with an eight-speed automatic transmission designed for smooth shifts and responsive performance. The drivetrain options, including four-wheel drive with a transfer case, are tuned to balance on-road manners with off-road and towing capability.
To place the current engine in context, earlier Colorado generations offered a broader engine lineup, including naturally aspirated gasoline engines and a diesel. Here are engines that have appeared in past Colorado models:
- 2.5-liter inline-4 gasoline engine
- 3.6-liter V6 gasoline engine
- 2.8-liter Duramax turbo-diesel engine
These options varied by model year and market. The current generation focuses on the 2.7L turbo as its primary gasoline powerplant, with no diesel or V6 option offered in the latest lineup.
The Chevy Colorado’s modern engine is a single, turbocharged 2.7-liter inline-4 that delivers strong torque and horsepower with an eight-speed automatic transmission, plus available four-wheel drive for rugged use. While older Colorado models offered a wider range of engines and even diesel options, the current model sticks with the turbocharged four-cylinder setup.
