In a test this month on Nürburgring Nordschleife, Electric RaceAbout built by Helsinki Metropolia University of Applied Sciences has made a new lap for road legal electric vehicle. Ralf Kelleners, a German race driver, needed only 8 minutes and 42,72 seconds on Electric RaceAbout (E-RA) to make a full lap of 20,832 km.
The popular, hilly and curvy track with long fast sections is also known as "Grüne Hölle" or Green Hell. It is a track widely utilized to benchmark the automotive top performance. The average speed for the lap was 142 km/h and the top speed at Döttinger Höhe 238 km/h.
During the testing, Kelleners reached 244 km/h. For the complete record lap, E-RA utilized 25,6 kWh, measured as energy taken from grid for the battery to recharge, resulting to energy consumption of 1230 Wh/km or 123 kWh/100km for the lap. Even if the E-RA powertrain gives out a peak power of around 300 kW throughout the lap, there were no overheating issues observed in batteries or motors typical to EVs.
The weather was close to perfect with dry and sunny, but it is also not too warm at about 15 degrees C ambient temperature. The E-RA was befitted with Nokian Z G2 high performance road tires, which are 245/40 ZR 18 in rear and 225/40 ZR 18 in front.
Two faculty members and around 25 engineering students have designed and built the vehicle from scratch. Interior and exterior styling was produced by the students from Institute of Design at Lahti University of Applied Sciences.
