Chevrolet Cobalt SS
Although discontinued, the Chevrolet Cobalt SS is famous as one of the best affordable performance cars. Available as a supercharged, turbocharged or naturally-aspirated model, the best SS was the turbocharged 2.0-liter four-cylinder Chevrolet presented in 2008.
The engine delivered 260 HP, which was astonishing at the time and more than any of its competitors. Also, the Cobalt SS had big tuning potential, so it was easy to get even more power from the engine. Although they based it on the regular Cobalt, the SS version was nothing like the boring economy car it originated from.
