Electric RaceAbout ran annual tests on the legendary Nürburgring Nordschleife track recently. The electric sports car, piloted by Jesse Krohn, completed the 20,8 kilometre track in 8:01.41 seconds, setting its best time to date.
“Project E-RA” is a research vehicle of Helsinki Metropolia University of Applied Sciences. This car has been designed from a clean sheet of paper to adopt the latest technology of electric powertrains and battery systems. The Electric RaceAbout has been developed over the years, setting various speed runs and records. Earlier this year the electric road legal sports car reached an average top speed of 281,36 km/h.
The team continued improving the performance and reduced the weaknesses of the car last year. Among the improvements are active rear wing control, suspension and an ABS brake system. The Torque Vectoring control system of the motors has also been improved since last year.
During the recent run at Nordschleife, Jesse Krohn, a young Finnish VLN- series driver had the honour to lap the ‘green hell’. “The driveability of the vehicle was good regarding its weight and the acceleration from 100 to 200 km/h was very convincing,” says Krohn, who drove the vehicle for the first time.
The testing period led to the second fastest lap around the Nordschleife track in the street legal electric vehicle group. The unpredictable Eifel climate didn’t worked in their favour as the car was on the track only three times in four days. “The low amount of laps did not help me get accustomed to the vehicle,” he continued. “Also, we had to start every lap with cold tyres and brakes.”
During the fastest lap, the battery of the vehicle heated up more than the team anticipated and the battery output power had to be limited halfway. Additional laps would have helped to optimize the vehicle setup, so it seems there is still potential for a faster lap time.
The best time for an electric road legal vehicle on Nordschleife still remains with Mercedes-Benz AMG SLS Electric Drive in 7:56.2 seconds.
