2005 Chevrolet Cobalt

The 2005 Chevrolet Cobalt was a compact car offered in coupe and sedan body styles, aiming for fuel efficiency and affordability. The base engine was a 2.2L Ecotec inline-4 producing around 145 horsepower and 155 lb-ft of torque, paired with either a 5-speed manual or a 4-speed automatic transmission.
