The first official images of the Mercedes SLS AMG Gullwing have leaked out ahead of Frankfurt We’ve been teased and tormented by the long, drawn-out tease for the Mercedes SLS AMG - the in-house replacement for the mighty Mercedes McLaren SLR. We’ve had what I thing is a first – an SLS Official Spy Video – and endless bits and pieces on the Gullwing.

Ford warms up new era of car-guy leaders

A minor temblor shook Dearborn, Mich., today with the announcement that Mark Fields, president of the Americas, climbed the golden corporate ladder to grab the chief operating officer ring, setting him up to succeed Alan Mulally in a couple of years. The move did not come as a shock-it only confirmed the whispers of auto industry Royal Watchers.

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.
