Performance wise, this maker has few peers, though they haven't always produced the most aesthetically pleasing of rides. Untill now. The Subaru WRX Concept is an angular, angry, menacing looking beast of a ride. A muscular sedan, its roof is comprized of carbon fiber to reduce weight and lower its center of gravity and it boasts a turbocharged engine, intercooler and quad tailpipes. Let's hope it doesn't remain simply a concept.
