Considered by many to be the most fun available for about $30,000, the all-wheel-drive, turbocharged Subaru Impreza WRX STI does a four-wheel drift into 2006 with an aggressive new look. The new face of Subaru, first introduced on the B9 Tribeca SUV, focuses on the brand’s aviation history by mimicking a fuselage with wings. The public’s response to the grille design has been mixed, but buyers of the 2006 Impreza WRX STI may not even notice – they’ll be focused on all-wheel-drive grip combined with 300 horsepower and 300 lb.-ft. of torque.
