The new BMW X5 costs from £42,590 for the sDrive25d We had the reveal of the new BMW X5 this week (which is either a new X5 or a facelift for the current X5, depending on how you look at it, and also the 2013 or 2014 X5) and now we have full UK prices for the new range. The starting point will be the X5 sDrive25d – BMW’s first rear wheel drive X5 and the first with a 4-cylinder engine – which will cost from £42,590 and comes with BMW’s 2.0 litre diesel which will give economy of 50.4mpg and emissions of 155g/km. BMW expect the same figures to apply to the next up the range – the X5 xDrive25d – which gets the same four-pot diesel as the sDrive version but has 4WD.

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.
