About 140 horsepower.
The 2.2 L engine in the Chevrolet Cobalt is part of GM’s Ecotec family and powered most base Cobalt models from 2005 through 2010. While 140 hp is the common factory rating, the exact figure can vary slightly by year and emission-spec calibration. It’s worth noting that the Cobalt SS used a different, more powerful engine and is not representative of the standard 2.2 L option.
Engine basics and what the rating means
The 2.2 L Ecotec in the Cobalt is a naturally aspirated inline-4 that was paired with either a five-speed manual or a four-speed automatic transmission. The engine prioritizes efficiency and reliability, delivering modest power suitable for daily driving. The most frequently cited figure for this engine in the Cobalt lineup is around 140 horsepower, with torque typically around 150 lb-ft.
Key performance figures you’re likely to see for the 2.2 L Cobalt at a glance:
- Horsepower: 140 hp
- Torque: 150 lb-ft
These numbers are representative of the standard 2.2 L Ecotec used in most US-market Cobalts from 2005–2010. Exact values can vary slightly by year, trim, and regional specifications, so the best way to confirm is to check the vehicle’s door jamb sticker or manufacturer documentation for the specific car.
How it compares with other Cobalt engines
Within the Cobalt lineup, the 2.2 L sits below the higher-output options. The 2.4 L family offered more power in some models, while the Cobalt SS used a different 2.0 L turbocharged engine that produced significantly more horsepower. If you’re shopping for performance, the 2.2 L is geared toward everyday usability and fuel efficiency rather than sport performance.
For buyers and enthusiasts alike, it’s important to distinguish between the standard 2.2 L and the performance-oriented variants to avoid expectations that don’t align with the car’s design goals.
Shopping notes for a used 2.2 L Cobalt
When evaluating a used Cobalt with the 2.2 L engine, verify the original specifications on the window sticker, review maintenance records, and confirm the engine code if possible. While the horsepower remains in the same general range, maintenance history can impact how the engine feels in daily driving.
Summary
The standard 2.2 L engine in the Chevrolet Cobalt typically delivers about 140 horsepower, with roughly 150 lb-ft of torque. It provides dependable daily performance and good fuel efficiency, but it is not the high-performance option in the lineup—the Cobalt SS uses a different engine with far more horsepower. Always verify the exact rating for a specific vehicle from official documentation or the manufacturer label.
