Paul, just clocked your post, Formula E is not new, its being running for years its only in the last couple its beeen brought to the forefront.
In fact one of my mates is in charge of this project who is ex F1,Renault,Honda.
Lord Paul Drayson is the the man behind this project and when i got a tour of their Oxford base i asked him if he was the Bernie of FE, he did snigger a bit.
The car is based on a Le Mans style racecar with the engine removed and the battery pack installed(dimensions are approc 300mm x 75mm x 450mm.
Paul Drayson also has 2 x number Aston Martin DBRS race cars in the unit as well.
They are currently working on remote charging because at present the car can race for 25 minute stints before having to return to the pits for a re charge,when you think about it the car is a project, its the technology behind it that is absolutely gobsmacking when they tell you all about bluetooth remote charging.
I have loads of pictures of my wee visit but was asked not to post any of them up, i think i did post up one of the Astons on my FB page..
If you follow Lord drayson on twitter or www.draysonracingtechnologies they give more info on progress.
