  • CUPRA puts the e-Racer to the #test in extreme conditions on the ski slopes of Andorra
  • 20mm higher suspensions and tyres with 420 studs each to drive on snow and ice
  • Cold weather is the best ally of the electric system as it cools the batteries

The countdown for the debut of the #cupra e-Racer, the first 100% electric #racing touring car in the World, in the new ETCR championship has begun. The Spanish brand's race team is working non-stop on the development of this electric race, putting it through a constant series of tests under the most gruelling conditions. This winter, driver Jordi Gené and the team of engineers led by Xavi Serra took the e-Racer to the limit on the snow and ice of Andorra's ski slopes.


What was the challenge like to adapt the car to low temperatures?

J.G.: It was actually quite easy. The key to electric cars is temperature management. We demand a lot of power from the engine, but the batteries run hot, not the motor. As we were working in very cold conditions, the low temperature had more than enough of a cooling effect on the batteries.

X.S.: One of the biggest challenges is how to manage recharging times, as the e-Racer is equipped with a 450 kilo battery that is equivalent to 9,000 mobile phones all connected at the same time. Its energy source consists in a total of 23 panels, each with 264 cells. When the batteries discharge you have to wait until they cool down before recharging them efficiently. Thanks to the cold, the process is much quicker.
