The low-carbon motor event that is EcoVelocity has returned to London once again, following the success of the 2011 event. The show features the latest in cutting edge technology from the world's leading car manufacturers and provides an opportunity for car enthusiasts to test drive the newest low-carbon and electric vehicles.

The 2012 EcoVelocity is the first UK car show to be carbon neutral and through its partnership with Carbon Neutral Investments, EcoVelocity will offset the carbon emissions of the show by supporting a hydro-electric project in India. The Telegraph reported that the EcoVelocity paddock would feature exciting and aspirational eco-friendly models.

Some of the models will be the established Fisker Karma and Tesla Roadster, from the US, while cutting-edge British cars like the Delta E4 Coupé and the Lightning GT supercar will also be on display. In addition, a number of mainstream models like the Vauxhall Ampera, Honda Jazz hybrid and CRZ, Nissan Leaf, Citroën C-Zero, Chevrolet Volt and Peugeot 508 RXH Hybrid will be seen.

"Having seen the success of EcoVelocity in 2011 first hand, CNI are delighted to form a new partnership for this year's event; to be held at London's ExCel centre," James Brown, CNI Co-Chairman said in a statement, adding, "EcoVelovity has taken the position as the UKs major motoring show, with all the exhibitors boasting impressive low emissions in their automotive products, it's important that the organisers can demonstrate the same values."

Some of the supercars on display at the 2012 event are:

Tesla Roadster -
The hand-built, carbon-fiber Tesla Roadster sets the mark for premium electric cars. This supercar, minus the supercar emissions, smoothly accelerates from 0-60mph in 3.7s.

Fisker Karma -
The Karma is the world's first true luxury electric vehicle with extended range. It combines the efficiency of electric drive with the range and freedom of petrol-powered cars, while offering the comfort and performance expected of a high-end sedan.

Delta E-4 Coupe -
The E-4 Coupe is a two door, four seat coupe which will initially be manufactured purely as a battery electric car. The car has also been package-protected for hybrid conversion either using a Hydrogen fuel cell or onboard generator.

Lightning GT -
The car offers no compromise between looks and driving pleasure. The Lightning GT can reportedly reach 0-60mph in less than four seconds.
