Infiniti releases another JX crossover teaser ahead of Pebble Beach

We get it, Infiniti. You're being coy. You release one small picture of the new three-row Infiniti JX crossover every week until Pebble Beach, when we'll finally see the full 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.

BMW Concept 6 Series Coupe

The BMW Concept 6 Series Coupe appears to be a thinly-veiled version of the upcoming production version, due next year. Like the current model, it retains a 2+2 coupe layout and while its exterior styling may not be as shocking as its predecessor's on its unveiling in 2003, it marks an evolution of the current BMW language. Its face has a subtly evolved kidney grille and more drawn-back headlamps.
