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.
