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.

CAR tech: how to eliminate turbo lag

CAR has tested a new breed of experimental super-diesel that literally leaves current technology standing and may banish turbo lag forever. We drove an Audi A6 3.0-litre V6 prototype fitted with an electric bi-turbo system which delivers a massive dose of torque from idle. The effect is radical, firing the saloon off the line like an R8 when the driver floors the throttle.

Aston Martin has finally taken the roof off the V12 Vantage, creating the new 2012 V12 Vantage Roadster, pragmatic nomenclature fans. Mechanically identical to the hard-top, it's on sale now, priced at a nice, round £150,000. Just a soft-top V12 Vantage, then?
