Subaru Impreza WRX STi  Generations

With it's flared fenders and wider stance, the five-door, all-wheel drive STI has a more aggressive look than the other, more sedate, Impreza's. Featuring a turbocharged 2.5-liter horizontally opposed four-cylinder engine paired with a six-speed manual transmission, this little rocket produces a whopping 305-hp. To plant all that power, Subaru utilizes a Driver Controlled Center Differential (DCCD) system, which claims to be the world's only hybrid mechanical/electronic limited-slip differential. Standard front seat mount, and front and rear curtain airbags offer occupant protection. Standard anti-lock brakes with traction-control and stability-control help reign the chassis in while driving at the limit of this cars potential.
