The Chevy Cobalt is available as a coupe or sedan, with a sporty SS Supercharged coupe filling the top spot with a 205-horsepower supercharged engine. Other Cobalts come with a solid-performing 145-hp, 2.2-liter four-cylinder, while a midgrade SS coupe and sedan feature a peppy 171-hp version. The vehicle's stiff structure does wonders for noise and vibration control, and makes for a solid-feeling ride regardless of terrain. Even the doors close with a solid "thunk." And crash protection is very good in front- and side impacts.
A 2.2-liter four-cylinder powers LS, LT and LTZ models. With 145 horsepower and 155 pound-feet of torque, the engine makes the Chevrolet Cobalt one of the faster econoboxes out there. The SS features an even more potent 2.4-liter version with 171 hp and 163 lb-ft of torque. The SS Supercharged coupe features a supercharged 2.0-liter four-cylinder good for 205 hp, 200 lb-ft of torque and a 7-second 0-60 time. The standard transmission is a five-speed manual with a four-speed automatic available as an option. The automatic is standard on the LTZ, and not available on the SS Supercharged. -Source Edmunds
