In The News From around the web


Subaru Impreza WR1
WR1's extra power and torque are achieved thanks to a revised engine control unit (ECU), high-flow catalyst and sports silencer.
For example, the Impreza WR1 will feature a driver's control centre-differential (DCCD) via a switch mounted next to the handbrake.
