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.
