Racing driver Sabine Schmitz has tested the Furtive eGT, an electric car out- fitted with Siemens’ motors, on the Nordschleife (north loop) of the Nürburgring – the world-famous racing track.
This circuit, nicknamed the ‘green hell’ is considered the ultimate performance test for a sports car.
The Furtive eGT, from the French auto- motive manufacturer Exagon Motors, achieved a top speed of nearly 240 km/h on the 20-km-long Nordschleife.
In collaboration with Siemens, Exagon Motors intends to build a small production series of the Furtive eGT starting in 2013. Siemens and Exagon Motors have been cooperative partners for a number of years at the well-known Andros Ice Race for electric vehicles.
Electric cars are quiet and produce few emissions but, until now, they have not had a very sporty image. Of late, however, a number of electric vehicles have been developed that seek to combine comfort, performance and environmental protection.
With the Furtive eGT sports car, Siemens has the opportunity to demonstrate the efficiency and performance of its motor technology. The Siemens global research unit, Corporate Technology, developed the power train and built a prototype. The electric motor experts from Siemens Drive Technologies will be able to combine this know-how with their own product experience to meet the agreed-on 2013 production launch.
At only 52 kg, the motor is one of the lightest and most compact units on the market. But that does not mean it is not powerful. During the test on the Nordschleife, it produced 125 kW of power – which is to be increased to 148 kW. This high power density is combined with a very high energy conversion efficiency of up to 97%.
With two of these motors, the car will produce two times 148 kW – in other words, 402 horsepower. It will accelerate from zero to 100 km/h in 3.6 seconds and have a top speed of 287 km/h on the racetrack. On public roads, the speed will be limited to 250 km/h.
The eGT’s range as a purely electric car is up to 400 km, depending on the driving style employed. The installation of an optional ‘range extender’ and a 25 ℓ tank will allow the electric sports car to cover more than 800 km.
A special feature of the Furtive eGT is its three-speed transmission, which harmonises well with Siemens’ control strategy for rapid shifting.
Formula E Electric Car Racing on the Horizon
Motorsport governing body the Federation Internationale de l’Automobile has plans for a new motor racing series designed strictly for electric cars. The new championship, known as Formula E, should begin in 2014.
A consortium of investors led by the Spanish billionaire Enrique Banuelos has a vision for the future of the motor industry over the coming decades. Chris Aylett, CEO of the Motorsport Industry Association, is convinced that Formula E “will be a very trendy, very modern, futuristic form of racing”.
Organisers admit that “a lot of research and development still needs to take place but, as we all know, motorsport has always been not only an important driver of research and development for racing as such, but was also a strong contributor to motor industry in general”.
There are many groups of students at many universities around the world who for years have tried to create a racing e-vehicle. Based on this and with the help of new smart materials, as well as progress in the field of batteries, they can be the right contributors in the new field of motorsport activities.
