The Subaru WRX STi combines racing car-like acceleration and handling with the practicality of a four-door, five-passenger sedan. For the price, the STi is also a performance-car value. Its 300-hp, turbocharged four-cylinder engine accelerates like a high-performance V8, while delivering reasonable fuel economy (20 mpg), albeit on premium fuel. The STi's handling is nimble. The trade-off is a stiff ride that is jittery but tolerable. There is also constant noise from the engine, drivetrain and particularly, the tires. For less money, you can buy the 230-hp Impreza WRX sedan or wagon. It isn't as quick as the STi version, but it's quieter and has a more comfortable ride.
