Inspired by Subaru's factory-backed FIA World Championship Rally series race cars and tuned for maximum performance, the Subaru WRX STI will not disappoint. In fact, the STI's turbocharged flat-four cylinder engine and firm suspension can excite all driving enthusiasts. However, its tenacious all-wheel-drive system and manual-only transmission are notable hallmarks of the sporty Subaru sedan. And if the STI is too spicy for you, there's always the less edgy-albeit-still-raw WRX. While the STI lacks the cargo space of rival hi-po hatchbacks such as the Honda Civic Type R, it's better equipped to conquer terrain in all four seasons thanks to its asymmetrical all-wheel drive system.
