THE Forester GT is the only car in its class to be powered by a turbocharged engine - it uses a detuned version of the 2.0-litre engine from the Impreza WRX. Subaru promoted the GT as the world's first off-road sports car when it was released in 1998 and rightly so, as it produces 20 per cent more power and torque than its nearest four-cylinder competitor - as well as even outdoing some of its larger V6-powered rivals.
