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.

New 2015 Mercedes S 65 AMG Coupe revealed – price from £183,065

The new 2015 Mercedes S65 AMG Coupe arrives The range-topping Mercedes S65 AMG Coupe has been revealed, and offers up its credentials as the perfect alternative to the Bentley Continental GT W12 with its 621bhp V12 delivering performance of 0-62mph in a 4.1 second whoosh. Even with its AMG badge, the S65 AMG Coupe is probably best thought of as the luxury take on the more aggressive and sporty S63 AMG Coupe – just as the V8 Continental GT is the sporty side of the Bentley Continental range – with its more effortless take on performance and power. There’s no doubt you get plenty of power and torque from the big V12, with 621 bhp and 737lb/ft of torque – driven to the back wheels through Mercedes’ seven-speed Speedshift automatic ‘box – on tap, enough to get to 62mph in 4.1 seconds and on to a 155mph limited top speed – but in a more creamy and effortless way than the S63.
