Electric Vehicle Sets Nurburgring Lap Record
Driven by German race driver, Ralf Kelleners, the average speed for the lap was 88.23mph and the top speed at Döttinger Höhe 147.89mph. Later on during testing, Kelleners reached even more impressive 151.61mph.
For the complete record lap, the Electric Raceabout (E-RA) consumed 25.6kWh, measured as energy taken from grid to recharge the battery. This results to energy consumption of 123kWh/100km for the lap.
E-RA has four motors – one per each wheel – designed jointly with Lappeenranta University of Technology and produced by AXCO Motors. The motor controllers come from Finnish electric drive manufacturer, Vacon. E-RA has full carbon fibre composite body to save weight for the powerful and efficient 33kWh lithium-titanate battery pack.
The test has clearly proven that using electric powertrain, it is possible to construct both efficient and high performance car which can also be used in regular traffic. On normal roads the average energy consumption for E-RA is only 145 W/km and on racetrack it can achieve 151.61mph top speed with modest consumption and minimal losses.
