Exagon Furtive eGT Shows Incredible Electric Supercar
Another electric car whizzes by on the Uber famous Nurburgring race track. But this time, it’s not Audi, Mercedes or BMW, it’s a French company that intrigued many with an interesting take on how and what an electric sport car should be. The electric Furtive eGT sports car from Exagon Motors topped nearly 149 mph, on the Nordschleife circle at the Nürburgring. The Furtive eGT was revealed earlier this year and finally unveiled at the Paris Motor Show.
Technically Speaking. The 115 lbs electric motor from Siemens powers the eGT and makes it one of the lightest and most compact units available. The overall 125 kW of power, 167 hp will be increased to 148 kW, close to 200 hp for the final production version. The eGT uses two of those Siemens electric motors pushing a combined output of 296 kW, or 402 hp. According to Mike Millikin at GreenCarCongress, the electric motors are liquid cooled and intelligently positioned centrally mounted and linked to a WCT, Without Cut Torque three-speed gearbox.
The two Siemens electric motors deliver a constant 380 lb-ft of torque up to 5,000 rpm giving the Furtive-eGT a 0 to 62 mph in 3.5 seconds. Its top speed on the racetrack will be 178 mph but in commercial use, it will be limited to 155 mph.
An EV With Gears. The eGT uses a three-gear system to make full use of the dual Siemens electric motor. With each gear change, one of the motors continues to power to the wheels. What this does is avoid break in the torque curve and maintains a uniform power distribution at all time. This also means the motors are always at their optimum range of power, torque and efficiency. All of this is achieved without a clutch in either mode, manual or automatic. All of this makes the Furtive eGT a truly potential electric vehicle that takes full advantage of its electric motor power while increasing energy efficiency.
As far as the batteries, the 360V Saft battery pack is rated at 53 kWh and is expected to retain more than 80% capacity after 3,000 charging cycles, which translate to roughly over 621,000 miles. That should reassure many a would be potential electric car buyer.
An EV With Range. Tesla is not the only electric car with range with range. If the Furtive achieves its expected range estimates, it should reach 224 miles over an urban cycle, according to the ECE15 standard, 193 miles combined cycle, on the NEDC standard, and finally 178 miles highway cycle with the EUDC standard.
Range Anxiety Anyone? A few months ago I wrote about this intriguing project that is not only an electric vehicle, EV but can also be configured as a plug-in hybrid, PHEV. An optional “range extender combustion engine” can boost the range to the almost mythical 500 miles barrier, using 6.6 gallons of fuel. Using four driving modes to please everyone, the Standard, Eco, City and Sport should make at least every happy.
The Sport mode will boost performance with quick acceleration, acceleration control and motor speed for gear changing. In the Standard mode, the motors function normally with full power that is optimized for gear changing, thus improving efficiency and driveability. The Eco mode limits the power to the motors in order to boost range. Finally, the smart touch is the City mode, which optimizes the Furtive eGT for low speeds and efficiency.
Other Technicalities. The Furtive eGT packs intelligent features, such as recycling the interior air to reduce most pollutants caused by other vehicles. As far as driving dynamics, the Furtive eGT uses a carbon-fiber body with an aluminum rear to support the two motors, gearbox and power electronics. The batteries are logically low in the floor, which lowers the center of gravity as much as 4’ 3” lower than a conventional GT. This almost eliminate roll on cornering, which should give it an exceptional ride and handling.
Hat Tip Mike!
The Exagon Furtive eGT sounded amazing then but felt more an technological exercise than anything a few months ago. What we have here is Exagon ready to build a small amount of units that is hitting a lot of high notes, with its Furtive eGT.
