With its electric drivetrain and innovative solutions, the Furtive-eGT rewrites the ground rules for contemporary GT sports cars. Not in terms of performance alone, but in terms of the new driving sensations delivered by a grand tourer designed as an electric vehicle from A to Z.
An exceptional electric GT sports car
Exagon Motors set out to develop an exceptional electric sports car that would combine the best of their experience in electric motorsports (Electric Andros Trophy) with today�s cutting-edge technologies. The specifications drafted by Luc Marchetti, CEO of Exagon Motors, established clear objectives: the Furtive-eGT had to combine exceptional performance with real day-to-day driveability. To achieve this versatility, Exagon worked with a number of leading European partners who brought their expertise to the project from the outset: Siemens, Saft, Michelin and Nokia. The result: the most exciting GT sports car around.
Original technologies and leading partnersThe Furtive-eGT combines an impressive sum of human expertise with technologies never before seen in cars. It is an innovator in all areas, from its latest-generation Siemens motors and Saft batteries to its carbon body, running gear developed with Michelin, three-speed gearbox with seamless torque delivery, acoustics by Focal and man/machine multimedia interface. The Furtive-eGT embodies a unique blend of expertise. No comparisons can be made with the existing market offering.
A GT made for the era of sustainable developmentThe Furtive-eGT is very much a car of its times, the era of digital cars and sustainable development, but it also reflects a long tradition in exceptional GTs. This long-haul traveller is a true 2+2, designed to comfortably seat four passengers with their luggage. The Furtive-eGT is designed as a versatile car, combining the ride and performance of a quality sports model with the comfort of a grand tourer.
A new sensory experience The electric drivetrain delivers original driving sensations with the torque coming in immediately. With constant torque of 516 N.m between 0 and 5,000 rpm, the Furtive-eGT is capable of phenomenal acceleration, sprinting from 0 to 100 km in just 3.5 s, with a top speed limited to 250 kph. As well as savouring the silence of this impressive performance, owners can take pleasure in owning a car with zero carbon emissions. Looking beyond figures, this is an experience that everybody should enjoy at least once in their lives.
French spirit and styleDesigned by Exagon MotorsTM, the Furtive-eGT is a car of classic, timeless beauty. It embodies a truly French approach to modern, prestige vehicles, far removed from passing trends and fashions. The Furtive-eGT is 4.46 m long with very short front and rear overhangs. The design is elegant and dynamic, while placing the emphasis squarely on aerodynamics. A car of pure, clean lines, the Furtive-eGT stands out from the crowd with distinctive features, such as the double-bubble roof, headlight signature and rear wings to optimise downforce.
2. Siemens electric motorsThe Furtive-eGT is driven by two latest-generation electric motors from Siemens Inside e-Car. Installed centrally on an aluminium cradle at the rear, and linked by the three-speed gearbox with seamless torque delivery, they drive the rear wheels of the Furtive-eGT (rear-wheel drive). From the driver�s standpoint, the two motors act as one even though the electronic controls allow them to operate separately. The two motors are liquid-cooled to maintain performance levels in all conditions of use.
These electric motors are among the most compact on the market. They each develop 148 kW � or 296 kW overall � a level of power equivalent to 402 bhp, for an outstanding level of efficiency. Maximum power of between 5,000 and 10,000 rpm is available in one-tenth of a second, with constant torque of 516 N.m (258 N.m x 2) between 0 and 5,000 rpm.

These motors, developed specially by Siemens for the needs of the Furtive-eGT, each weigh 51 kg. Viewed against their individual rated power of 148 kW, this gives them energy density of 2.901 kW/kg, an excellent figure, with efficiency close to 98%. Two inverters, also developed specially for the Furtive-eGT, distribute electric power by converting the direct current from the Saft battery into alternating current. The inverters drive the motors in two modes, based on torque or engine speed, modifying amplitude and frequency as necessary. The �supervisor� control electronics were developed internally by Exagon.
