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.

Fancy driving Hyundai’s Hydrogen ix35 Fuel Cell?

As part of the European Hydrogen Road Tour, Hyundai are offering members of the public the chance to drive the ix35 FCEV. As we revealed back in August, the Hyundai ix35 FCEV – Hyundai’s hydrogen-powered electric ix35 – is going in to production before the end of 2012, the first proper production fuel cell vehicle…in the world. The initial production run is small – just 1,000 cars – but Hyundai are planning to put the ix35 FCEV in to full production by 2015, by which time they’re hoping there will be a viable hydrogen refuelling infrastructure in place.

The 500-hp club: The room is getting crowded

The number of fire-breathing wedge-shaped supercars and hot sedans and coupes that can pump out 500 hp or better has nearly doubled in the past five years to more than 70. A decade ago there were just two members of the 500 hp club in the United States: the Ferrari 575M and Lamborghini Murcielago.
