CUPRA e-Racer

This is how an electric race car is built

Martorell,  05 March 2018

  • The CUPRA e-Racer, the world’s first 100% electric touring competition car, can reach 270 km/h
  • A battery pack with 6,072 cells and four engines for a vehicle that accelerates to 100 km/h in slightly more than three seconds
  • A design and mechanical challenge that took over 20,000 hours of work to complete

2) A battery that weighs half a tonne: At 450 kilos, it represents a third of the car’s entire weight. For this reason, “its positioning was one of the biggest challenges we had to face”, says Xavier Serra, the technical director of this project. It is so big and heavy that we had to distribute its volume throughout the lower part of the car to maintain its balance and functionality.

3) Four engines on this car: “One of this vehicle’s most surprising aspects has to be its power”, affirms Xavier Serra. This model is equipped with four engines, located at the rear, enabling “the CUPRA e-Racer to reach 12,000 revolutions, compared to the 6,500 of a petrol powered race car, and all with a single gear”, Serra confirms.

4) A winning design: “The main goal was to improve aerodynamics”. For this reason, the door mirrors were replaced with mini cameras, “to make the car more dynamic”, adds Serra. The driver can see everything that is happening around him on a large screen built into the dashboard.

5) A mosquito on the asphalt: Serra affirms that the feeling at the wheel is different to that of a petrol powered car and the first thing that strikes you is “its acceleration”. The sound this vehicle makes is also something new: “Unlike a conventional car, this electric model makes a humming noise similar to a mosquito”.

6) From a traditional Leon to a race car: The new CUPRA e-Racer model was built on the chassis of the SEAT Leon. The structure was enhanced with safety elements such as an interior roll bar to make it suitable for competing.
