Chevrolet Cobalt SS Turbocharged
The Chevrolet Cobalt SS Turbocharged is one of General Motors' most remarkable performance bargains and one of the greatest front-wheel-drive performance cars ever produced in America. When it was introduced for the 2008 model year as a replacement for the earlier supercharged Cobalt SS, it represented a quantum leap in capability that few expected from a car wearing a Chevrolet badge on an economy-car platform.
The heart of the Cobalt SS Turbo was GM's LNF 2.0-liter direct-injection turbocharged engine, producing 260 horsepower and 260 lb-ft of torque — figures that were extraordinary for a front-wheel-drive compact in 2008. The engine was paired exclusively with a five-speed manual transmission from Aisin, and the car featured a limited-slip differential to help manage the prodigious torque through the front wheels.
But the Cobalt SS was far more than just an engine swap. GM Performance Division fitted Brembo four-piston front calipers, a fully independent rear suspension with a Watts link (unique among Cobalts), FE5 sport-tuned dampers, and a comprehensive suite of chassis reinforcements. The result was a car that could generate over 0.90g on a skidpad and lap the Nurburgring Nordschleife in 8 minutes 22 seconds — at the time, the fastest lap by a front-wheel-drive production car.
The acceleration was equally impressive. Car and Driver recorded a 0-60 time of 5.5 seconds, a quarter mile of 13.9 seconds at 102 mph, and a top speed of 155 mph. These were performance figures that rivaled or exceeded cars like the BMW 335i and Audi S4, at a fraction of the price.
The SS Turbo also proved its mettle in motorsport. It won multiple World Challenge Touring Car championships and became a popular platform in grassroots racing series. The combination of affordable entry price, genuinely competitive performance, and robust mechanicals made it an ideal club racer.
Production of the Cobalt SS ended in 2010 when the Cobalt was replaced by the Cruze. No direct performance successor was offered, and the SS Turbo remains the high-water mark for GM's compact performance car efforts. Clean, unmodified examples are increasingly sought after by enthusiasts who recognize the car's significance.
Inspect thoroughly for modifications — most Cobalt SS Turbos have been tuned at some point. Check the turbo for shaft play and listen for wastegate rattle. The LNF engine is robust but the timing chain tensioner can be a problem at higher mileages. Verify the limited-slip differential works properly. Brembo calipers should be inspected for pad wear and rotor condition. Interior quality is basic Cobalt economy car — expect wear and rattles. Check for evidence of track use (brake dust buildup, worn tires unevenly). Unmodified, well-maintained examples command the highest prices.
The Cobalt SS was offered in two performance variants: supercharged (2005-2007, 205 hp) and turbocharged (2008-2010, 260 hp). The turbo version was a dramatic improvement, with a different engine, better brakes, and an upgraded rear suspension. Only the coupe body was offered as SS Turbo. Production numbers for the SS Turbo are estimated at approximately 7,000-10,000 units total.
