MERCEDES E-CELL: THE ELECTRIC SLS
Electric supercar prototype revealed
The E-cell is powered by four electric motors, with a pair in each axle and driving all four wheels. Each motor revs to 12,000rpm and all four make a combined 519bhp and 649lb ft of torque.
The battery packs are Lithium polymer and are sited behind the cabin and on the transmission tunnel.
The front electric motors mean the petrol SLS's double wishbone suspension has been abandoned in favour of push-rod dampers and a more compact multi-link set-up.
Other tweaks to the SLS include an extendable front splitter and a larger rear diffuser, so the electric car can generate more downforce than its petrol sister, while inside there's a 10-inch touch-screen display.
