New video: Next generation Porsche Turbo

Highlights: Just when Ferrari and Lamborghini thought they had the 911 Turbo covered with cars like the 360 Stradale and Gallardo, Porsche unleashes a new, more powerful version of the blown 911.

Filmed here for the first time, Stuttgart's latest Turbo will go on sale towards the end of 2005 as part of a thoroughly revised 911 line-up. At its heart is a reworked version of the current car's twin-turbo 3.6-litre flat six with over 450 HP in standard trim - up by 30 HP. Exact technical details remain scarce, though Porsche is thought to have side-stepped direct injection - a technology it has already developed - in raising the turbo's output. Instead, the increase is said to come from a series of subtle enhancements to the ECU, coupled with further improvements to the VarioCam variable valve timing system and a moderate increase in boost pressure.
