The Chevrolet Cobalt SS is a sport compact high performance version of the Chevrolet Cobalt, featuring three inline-4 Ecotec engines, built on the General Motors Delta platform. (more...)The car debuted with a 205 hp (153 kW) supercharged 2.0 L engine in late 2004, the only transmission option being the F35 manual of GM Europe. The engine had been first introduced one model year prior on the Saturn Ion Red Line. For 2006, a naturally-aspirated Cobalt SS with both automatic and manual transmission options was one of three Delta cars to carry GM's new 2.4 L,171 hp (128 kW) engine. A second 2.0 L engine exclusively mated to the F35, with power upped to 260 hp (194 kW) by way of a turbocharger, revived the Cobalt SS in the second quarter of 2008 after a brief hiatus. (less)
