The Cobalt compact sedan and coupe came out in 2005 as replacements for the dated Cavalier. Changes and updates for 2007 include a bump in output for the Cobalt’s standard 2.2-liter engine, which now produces 148 horsepower (vs. 145 previously) as well as the optional 2.4-liter engine offered as the base engine in the sporty SS. It climbs to 173 horsepower (vs. 171 previously). The top SS engine, a 2.0 liter supercharged four-cylinder, continues to produce 205 horsepower. A new remote start system can be ordered on automatic transmission-equipped models, LT trims get a newly optional 16-inch wheel package and 18-inch polished rims are available on supercharged SS coupes. Sport Red Tintcoat has been added to the exterior color roster. Models ordered with anti-lock brakes also get traction control. Side-impact and curtain airbags are available optionally.
