Are you familiar with the French e-sports car – that we’ve heard may optionally be range extended – and that looks a bit more potent than a Tesla Model S and more exotic than the Roadster? Then again, it ought to be excellent, costing five times more.
This week at the Salute to Style event, at the Hurlingham Club, in London, Exagon Motors will have on display its Furtive eGT all-electric luxury sports car.
The company’s Web site is limited for details, but high on superlatives for a car that at current exchange rates may cost $528,000 (388,000 euros).
Among specifications divulged from a press release from last year, is the car will have “the first monocoque light carbon fiber body” weighing just 273 pounds. Total curb weight is estimated at around 3,600 pounds, or about 1,200 pounds lighter than a Tesla Model S.
Propulsion is via two Siemens motors, said to be extremely light and compact, for an output of 402 horsepower and 380 pounds-feet of torque.
Said rear-wheel-drive power is directed through a Exagon’s own ZTI three-speed semi-automatic gearbox “with seamless torque delivery.”
On each gear change, one of the two motors continues to transmit power to the wheels. This process avoids any break in torque in order to maintain power at all times. Furthermore, the motors function continuously within their optimum range of power and efficiency, enabling the vehicle to take full advantage of their power and to increase energy efficiency.
This should enable the vehicle to sprint to 60 mph in 3.5 seconds, and top out at a limited 155 mph. Range (aka “autonomy”) has been previously estimated as follows:
• Autonomy at a constant speed of 50 km/h (31 mph) : 402 km (249 miles)
• Autonomy at a constant speed of 90 km/h (56 mph): 288 km (178 miles)
• Autonomy at a constant speed of 110 km/h (68 mph): 241 km (149 miles)
Autonomy at a constant speed of 130 km/h (80 mph) : 197 km (122 miles)
The liquid cooled, battery pack weighing 450 kg is by Saft, is rated at 53 kilowatt-hours.
In 2012 a report prior to its showing in Geneva, talk was of a range-extender being made available.
Unclear is whether the RE is still in the plans, but the last report about it said 6.6 gallons (25 liters) of fuel will extend range (on a generous euro test cycle) to 501 miles (807 km) in urban cycle or 457 miles (735 km) in the combined cycle.
Less ambiguous is the vehicle is being positioned for people willing to pay five times the price of a Model S, and following is the company’s marketing verbiage:
Define an object or a means of locomotion, describe an emotion or develop a vision, demonstrate power or evoke intensity. The Furtive-eGT calls on us to alter our approach to the prestige sports car – an approach that fantasized about excessive and tortured aerodynamic styling; that delighted in the roaring and whining of past times; that put performance in conflict with the environment. Today, the criteria have changed. Electrical power propels you prophetically into a new automotive era – an era of unprecedented audacity that arouses troubling, hard-to-describe sensations. With the Furtive-eGT, Exagon Motors brings back the notion of driving as sport by combining pioneer spirit, advanced technologies and French know-how in luxury automotive design.
The title of the above passage is “Unique” and true enough, the car is exclusive, and being presented as beautiful automotive art doing the most with present technology.
Compared to the $980,000 1,100-horsepower Rimac which is being produced in a series of eight units, it’s only half the price, and still unique.
Pending the London showing July 17-19, look for more news or photos of the latest on this extreme EV, or check out the company’s Web site. Following is a promo video from Oct. 2012 of the vehicle at the Nurburgring.
Thanks to its extraordinary technical achievements, the conquest of space has made its mark on our technology-oriented planet by offering mankind the long-dreamed-of and unhoped-for opportunity to delight in an otherworldly spectacle. Among all these innovations, the lithium-ion battery will prove very useful, now and in the future. This artificial satellite perched 36,000 km overhead is chasing the stars at 11,000 km/h.
