French race team Exagon Engineering will branch out into road cars when it launches this hybrid 2+2, the Furtive-eGT, at this week's Paris Motor Show.

The new car has been developed with input from several top-line engineering companies, including Siemens Corporate Technology (engines), Saft (batteries) and Michelin (tires).

The 14.5ft Furtive-eGT has two electric motors, each producing the equivalent of 168hp. Exagon claims the car can crack 0-62mph in 3.5sec and reach a limited 155mph. Its range is around 250 miles on electric power alone, but a small generator can extend this to just over 500 miles, using 5.5 gallons of gasoline.

Exagon does have prior experience with electric vehicles: it developed a one-off electric prototype Andros Trophy ice-racer during 2009. It aims to put the Furtive-eGT on sale before the end of 2012.
