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 Citroen C1 revealed ahead of Geneva debut

The new Citroen C1 (pictured) revealed ahead of Geneva debut We’ve had the proper reveal of the new Peugeot 108 and a bit of a teaser photo for the new Toyota Aygo, and this morning we get the trio completed with the reveal of the new Citroen C1 ahead of its Geneva debut. We’d call the new C1 a 2014 model, but for some reason Citroen gave the current C1 an overhaul only a few months ago and made that a 2014 model, so we probably have to refer to this new one as the 2015 Citroen C1. Whatever model year to attach to it though, the new C1 is just a new Aygo or new Peugeot 108 in Citroen clothes and therefore offers much the same as those two cars.
