The Paris Motor Show is about to get underway and the next 72 hours will no doubt see an unprecedented number of new electric and hybrid vehicles, so it’s not surprising that a few companies have jumped the gun in showing new cars to avoid getting lost in the publicity avalanche. One doing just that is a new automotive brand (as least as a manufacturer of whole cars) emanating from French company Exagon Engineering. The figures for the Furtive eGT are astoundingly brisk - 100 km/h in 3.5 seconds and a top speed of 155 mph (250 km/h).

The 2+2 Exagon Furtive eGT runs two Siemens 168 hp (125 kW / 170 PS) motors for a total of 336 horsepower and an electric-only range of 400 kilometers (250 miles) before the petrol engine generator kicks in to double that distance before you need to stop.

The press conference didn't yield much more information, other than the fact that the car is electronically limited to its 155 mph (250 km/h) top speed because it is actually, unbridled, capable of 186 mph.

The key thing we couldn't find out was exactly the configuration of the range extender engine - no details and no-one is saying.

The press conference on the second day at Paris was postponed because the French President was so taken with what he'd read about the Exagon, he wanted to see it. Hence the 9.30am press conference was rescheduled while the Furtive eGT was ferried off the stand to be seen by the President, and returned by 2.30pm. Nice for some, heh.

In actual fact, Exagon's technology, derived from the cold hard world of sports car and GT racing, looks like a sound base for producing performance road cars, and the French pride which the car has generated, seems well founded.
