The Chevrolet Cobalt is a compact car introduced by Chevrolet in 2004 for the 2005 model year. The Cobalt replaced the Cavalier as Chevrolet's compact car. The Cobalt is intended to compete with compact cars like the Honda Civic, Toyota Corolla, Mazda 3, and VW Jetta.
It is available as both a coupe and sedan and is based upon the GM Delta platform, along with the Chevrolet HHR, Pontiac G5, Saturn ION. All Cobalts are currently manufactured at GM's Lordstown Assembly plant in Lordstown, Ohio, Although the EPA lists the Cobalt as a subcompact, the Cobalt is still a compact car.1 Specifications3 Performance5 Engines7 Racing

The LS became the base model while the LT was marketed as a mid-range package.
2007: Both engines were retuned for more power while retaining the same fuel economy. The 2.2 L Ecotec is now rated at 110 kW (148 hp) with the 2.4 L Ecotec rated at 130 kW (173 hp). Other changes include a new console, new steering wheel and new radio head unit that features an audio input jack. In addition, all models except the LS and LT1 now use a 5x110 wheel bolt pattern. The LS and LT1 retained the standard 4x100. In addition, the 2007 model year marked the introduction of a new 32-bit computer that replaced the 16-bit unit from 2006.
Performance
The Cobalt is available with the SS performance package. There are two engine choices: the naturally-aspirated 2.4 L Ecotec rated at 171 bhp (129 kW) and the 2.0 L supercharged Ecotec engine rated at 205 bhp (155 kW). GM currently offers dealer-installed performance upgrade packages called stage kits that are covered by factory warranty. The Stage 1 kit consists of new fuel injectors and a reprogram of the ECU, and yields up to a 30 bhp (22 kW) improvement. The Stage 2 kit consists of new fuel injectors and the same reprogram with a smaller serpentine belt and pulley for the supercharger, producing a 40 bhp (30 kW ) improvement and 30 ft-lbs(40 Nm ) of torque. Both stage kits increase the engine redline to 7000 rpm. Chevrolet Cobalt LTZ sedan

The Cobalt, much like the Cavalier before it, is one of GM's best-selling vehicles. While sales did dip in late 2006, many cite lower gasoline prices as a result, thus allowing consumers to buy SUV's instead of compact cars. Nevertheless, the vehicle remains popular, especially in the Youngstown, Ohio area[citation needed] where the Lordstown plant is located as well as in the Pittsburgh area nearby where the Cobalt (much like the Cavalier before it) is the best-selling vehicle overall in the region.[citation needed] Model Year Sales 20052006 Racing
