This further distributes torque - this time to whichever rear wheel offers the most grip. The P1 also shares the Impreza Turbo's limited-slip rear differential. But in wet, muddy or icy conditions, the viscous coupling senses which axle has the most grip and distributes torque accordingly. In normal and dry road conditions torque is distributed 60/40 between the front and rear wheels. This features a centre differential with viscous coupling. Power leaps from the standard Turbo's 218bhp at 5,600 rpm to 280bhp, while torque has increased to 363 Nm compared to the ‘normal' model's 290 Nm at 4,000 rpm.įundamental to the Impreza Turbo's ‘cult car' reputation for dynamic handling and grip in all weather conditions is its all-wheel-drive (AWD) system. At its introduction it was the most extreme Impreza on the UK market and the only two door version of the Impreza. The P1 (short for Prodrive One) was especially developed for the UK market by a joint effort of Subura, Subaru Tecnica International (STi, Subaru's racing department) and Prodrive (runs the WRC campaign for Subaru).
The 1999 London Motorshow saw the introduction of this, the Subaru Impreza P1.
