The Chevy Cobalt - From 2005 to the 2010
Originally manufactured in 2005 on a GM Delta platform, the Cobalt is the replacement to the Cavalier in the Chevy compact car vehicle class. A conventional front-wheel-drive car, it was available in several different models including the base coupe and sedan, and improved on its predecessor with each passing year.
The Cobalt base model was introduced with front rotor brakes, 15" wheels, and a 2.2 liter 145 horsepower engine with 155 pounds of torque. The coupe had a standard 5-speed manual transmission or an available 4-speed automatic, while the sedan offered a 4-speed automatic.
Cobalt's exterior proved longer (180.3 inches) and wider (68.4 inches) than most other cars in its class, and the clean and crisp lines of the modified design were pleasing to the eye.
The coupe 97 cubic feet of interior space, on par with a standard compact model, and the sedan had slightly more with 101 cubic feet. Both had 13.9 cubic feet of truck storage space.
This next year added the SS to the Cobalt line-up, which was equipped with a 2.4 L Ecotec engine. The LS became the base model and LT was bumped to a middle range level. Additionally the GM "Mark of Excellence" symbol was added to both the front and rear fenders of all the Cobalt line-up.
The power was turned up when the engines were reworked, giving it some added get-up as well as fuel economy. New steering wheel, console, a radio unit with an audio input jack, and the introduction of the new 32 bit computer instead of the 16-bit one that the 2006 model had.
A change-up happened resulting in the SS coupe and sedan being renamed "Sport Coupe" and "Sport Sedan" as the new Cobalt SS came out. The new SS featured a 260 horsepower turbocharged engine that replaced the previous one. During the year fuel economy was increased again to the LS and 1LT, as well as adding manual transmission, EM radio, and side-impact airbags to them.
Both the "Sport Coupe" and "Sport Sedan" were deleted during this year, along with their engines. They were replaced with the 2.2 L LAP engines, which provided better fuel economy and power. An SS sedan was added to the lineup, along with three new exterior colors, Bluetooth capabilities, and reconfigurable performance display (RPD) on the SS Coupe.
Coupes and sedans remain largely unchanged from earlier versions in 2010, which is reportedly their last model year. The high performance models were removed. Anti-lock brakes (ABS) are added as available safety features, along with traction control, antiskid control, and curtain-side airbags, and Wireless cell-phone link, and USB port (for digital music players) are added as available options.
