Porsche Carrera GT Wallpaper

Porsche Carrera GT Wallpapers in standard and widescreen resolutions Porsche originally planned on  building 1500 Porsche Carrera GTs, but in fact only 1270 were actually built, with almost half of these going to the US. Just five standard colours were available on the Carrera GT (although Porsche would produce special paint finishes on request) and all featured a six speed manual ‘box and a base list price of $444,000 + tax. The limited production of the Porsche Carrera GT has helped it retain much of its value – a 2004 Carrera GT would still command in the region of $350,000.

First Sight: Peugeot HX1 concept

Porsche 911 GT3 R Hybrid (2011) first official pictures

Porsche has released details of its updated 911 GT3 R Hybrid – the 2010 original nearly won last year's Nurburgring 24hr race before (ironically) it retired with petrol engine failure.  The 2011 Porsche 911 GT3 R Hybrid – the lowdown Before this report disappears in a chorus of ‘it looks the same as last year’s one’, let's outline where Porsche’s engineers have been busy. At the unfashionable end of the car remains a 4.0-litre flat-six engine producing approximately 470bhp. Up front are twin electric motors, now producing 75kW of power each (up from 60kW) and combined these give the GT3 R Hybrid a 197bhp electric boost, which can be programmed to activate automatically via the throttle pedal, or manually selected during overtaking. F1-derived hybrid tech for the 911 GT3 R Hybrid Power for the two electric motors doesn't come from batteries, but flywheel accumulator technology from Williams Hybrid Power, an offshoot of the Williams Formula 1 team. The flywheel, encased in a carbonfibre safety cell in the space where the passenger seat would be, spins at up to 40,000rpm and acts as a mechanical energy store for the electric motors. Regenerative braking feeds energy back into the flywheel system – no surprises there, as the technology is derived from Williams' exeprience with Kinetic Energy Recovery Systems (KERS) in F1.
