Metropolia’s Electric RaceAbout electric car (E-RA) reached a new street legal electric vehicle top speed record in Lappeenranta, south-eastern Finland.
Janne Laitinen, the chief test driver at Nokian Tyres, took E-RA to a new ultimate racing speed of 281 km/h in the Unlimited Racing Festival at the Lappeenranta Airport on June 28.
Janne and E-RA achieved 277,40 km/h when racing down the 2500 meters long runway with moderate headwind. After just turning the four motor equipped E-RA around at the end of the runway Janne rushed back setting an even more impressive top speed of 285,31 km/h. This results an average top speed of 281,36 km/h (174,86 mph) for two directions.
Look at the video of the speed record drive.
The acceleration numbers from the record runs clearly demonstrate the strength of the E-RA direct drive concept. Picking up the first 100 km/h is not very fast for a sports car but adding the next 100 km/h takes only a little longer. The results are:
Electric RaceAbout is made by Metropolia’s students and experts in co-operation with more than 60 partners. Lappeenranta as a venue has a special meaning in the E-RA’s story. The traction motors for the car were designed by Lappeenranta University of Technology in 2009 and built at the local motor manufacturer AXCO Motors. Also the four inverters controlling the impressive 150 kW peak power motors come from another Lappeenranta based company called VISEDO.
”We at the E-RA team are very pleased to be able to demonstrate that the story of E-RA continues strong as ever, four years after the car was first shown to public and finished second in the Automotive X PRIZE competition”, Metrpolia’s Project Manager Sami Ruotsalainen says.
