Audi RS5 engine confirmed, plus RS5 cabrio

By Tim Pollard (artist's impression by Radovan Varicak) Motor Industry 13 May 2009 13:44 Audi will fit a refettled naturally aspirated 4.2-litre V8 to its secret new RS5, CAR can confirm. We had previously reported the RS5 would use a twin-turbo iteration of this engine, but a senior source has told us it will not feature forced induction. We’re told it’s the same high-revving engine that powered the outgoing RS4, albeit spruced up with the latest Ingolstadt know-how.

New Porsche 911 GT3 (991) technical highlights (video)

Ahead of its arrival with customers, Porsche has delivered a new video of the GT3 designed to make it clear just how some of its technical highlights work to make the GT3 swifter and more nimble than ever before. Power is of course the key to the GT3 – 468bhp and 324lb/ft of torque – but the power is no good unless the GT3 can put that power down as efficiently as possible in all circumstances. Porsche assert that the GT3′s chassis is engineered for Motorsport, and key elements of the new GT3 make it even more able.

Pagani Zonda Revolucion is the last ever Zonda. Apparently.

The Pagani Zonda Revolucion – the ultimate Zonda We’ve lost count of the number of ‘Special Edition’ Zondas Pagani has churned out over the years, but it’s probably close to the point where a non-special Zonda is rarer than the special editions. Now we get treated to one last special edition Zonda with the Pagani Zonda Evolucion, an evolution of the track-only Zonda R promising even more extremes of performance and price. The Evolucion’s 6.0 litre V12 engine produces a massive 789bhp which, thanks to a weight of only 1070kg, promises to be unbelievably quick with a power to weight ration of 749bhp per ton – better than the Veyron.
