Think City EV Cup Edition (2010) first official pictures

Manufacturers have been trying to make their racers more economical for some time now; Audi and Peugeot have produced diesel Le Mans winners and CAR reviewed the Porsche GT3 R Hybrid in the June 2010 issue, but this the most recent fully electric offering from Norwegian company Think.   Think has followed the traditional road-racer conversion for this one-off prototype, by stripping out most of the interior and space for the passenger, using Perspex instead of glass in the windows, installing a solitary lightweight bucket seat and lowering the centre of gravity. The company claims the diet reduces the Think's weight by nearly 70kg; that's the same saving as a Lamborghini Gallardo Superlegerra, remember.

Red Bull race in L.A. draws 111,000

These events have been held regularly since the inaugural race in Belgium in 2000.

We all know what a petrolhead Black Adder and Mr Bean actor Rowan Atkinson is, and most of the car world knows he owns a McLaren F1, and that he had a nasty accident in it in 2011. Rowan lost control of his F1 in damp and unpleasant conditions on the A605 near Peterborough and ended up going backwards in to a tree.
