These are the first official renderings of the all-electric E-Wolf E2 supercar, slated to go on sale in 2011 – and battery-powered cars don’t get any more potent than this.

The two-seater E2 is the brainchild of German firm E-Wolf, and looks to be styled on a combination of Ferrari Enzo headlights and bonnet, with Lamborghini Reventon front air-intakes – thanks to its origami-style surfacing. Performance is not quite as closely matched to the two Italian exotics though – zero to 100 km/h in less than five seconds and a top speed of 228 km/h.

A lithium-ion battery pack powers four electric motors, one in each wheel, with a combined power output of 391 kW and over 1 000 N.m of torque. The target kerbweight is a featherlight 900kg, giving the E2 a similar power to weight ratio as some of the top performing supercars.

Useable range on a full charge is claimed to be in the region of 296 km, although that sounds a little optimistic at this stage. What’s more, with a high-voltage power outlet the cells can be fully topped-up in just half an hour.

So far the E2 only exists in computer-generated form, but its designers promise the car will be able to reach a top speed of 250 km/h. Hopefully the production version will stay true to the concept’s lines.

Lamborghini has inadvertently revealed the open air sibling to its highly exclusive and equally expensive Reventon model, after the official gallery found its way on to the web. Like the Coupe version which made its debut at the Frankfurt Motor Show two years ago, the Reventon Roadster features the same stealth-fighter inspired design.

The Reventon Roadster will be powered by the same 6.5-litre V12 engine found in the Coupe, developing peak power of 478kW and 660Nm. This is coupled with a six-speed E-gear transmission and all-wheel-drive as standard. Performance should match its aggressive appearance, accelerating from zero to 100km/h in just 3.4 seconds and on to a top speed of 340km/h.

With all 20 Reventon Coupes finding an owner, it is safe to assume the expected 1.2 million Euro price tag for the Roadster won’t be a problem. Full details and specifications will be released when the car is officially unveiled at the 2009 Frankfurt Motor Show.
