Mercedes SLS AMG E-Cell (2010): the electric SLS

Following the unveiling of Tesla's updated Roadster 2.5, Mercedes is showing off its iteration of an all-electric sports car: the SLS AMG E-Cell. While the regular SLS pumps out 563bhp and 479lb ft from its 6.2-litre V8, the SLS E-Cell has four synchronous electric motors, powering all four wheels for a combined output of 392kW (equivalent to 526bhp) and a mammoth 649lb ft of torque. Crucially, all of that power is accessible from zero revs, allowing the E-Cell to sprint to 62mph in four seconds dead.

BMW 7-series facelift (2012) first pictures

BMW has given the 7-series the mildest of mid-life facelifts for 2012 – with a series of cosmetic tidy-ups, fettled engines, extra kit and the UK's first hybrid 7-series. The ActiveHybrid7 isn't the most expensive 7-series (that's the 760Li at £101,805), but at £66,040 the petrol-electric saloon is some £8k pricier than the biggest-selling 730d. As the diesel is also cleaner and more economical, we suspect the hybrid Seven will remain a niche seller over here.
