The Pontiac G5 derives from the Chevrolet Cobalt, from which it differs only in several aesthetic aspects. And like the Cobalt, it is available as a sedan and a coupe. There are few changes for 2009 since GM is set on replacing this model soon. Nonetheless, the engine was reworked so as to produce more power, but be more fuel-efficient. Introduced in 2005 under the name Pursuit, this is its fifth year of existence.
