Shock therapy: Merc’s electric SLS
TopGear does the morning rounds in the world’s fastest milk-float: the all-electric Mercedes SLS E-cell
Posted: 05 May 2011
Visually, it's almost identical to the existing car, but the E-cell has some big aero changes to make it 10 per cent more slippery. The front apron has been re-profiled and brought forward to optimise airflow along the car's underbody. An extendable front splitter tilts downwards above 75mph and helps accelerate air under the car. Because the E-cell doesn't need an exhaust system, the rear diffuser is bigger and more aggressively angled to generate extra downforce. The lightweight wheels are new, and look like the moon discs you see on Bonneville salt flat record breakers.
There’s an E-cell badge on each front wing and the special ‘lumi-electric magno’ mustard-yellow paintjob is memorably lysergic, but other than that it looks like a stock SLS.
