On the Cupra E-Racer Electric Race Car from SEAT, seen the light of day at the Geneva Motor Show. Already in March of last year, further details of Seat Cupra E-race car were known. The world’s first fully electric tour racing car will compete for the first time in the new race series ETCR for the first time.
Battery turns third of the total weight of the SEAT CUPRA E-RACER
At the heart of the vehicle is certainly the 450 kilograms of heavy battery. This makes Ca. One third of the total weight and was the development of the touring car the biggest challenge, according to the development leader of the Seat Cupra E-Racer, Xavier Serra.
In order to impact as positive as possible on the driving dynamics, the battery in the vehicle is as low as possible. The battery consists of 23 modules with a total of 6.072 individual battery cells, which provide approximately the same performance as 9.000 combined mobile phones.
The electric racing vehicle is powered by four engines, which together offer a 300 kW permanent and 500 kW peak performance. As a result, the Cupra E-Racer accelerates from 0 to 100 km / h in just 3.2 seconds. The tip he reaches at 270 km / h.
The Cupra E-Racer builds on the body of the Seat Leon. The structure of the vehicle was supplemented by appropriate security elements. A roll bar in the interior should probably be the clearly recognizable security element here to make the cart competitive.
As usual in electric cars from road traffic, the Cupra E-Racer also sets on recuperation. Inside, the driver receives a variety of data for vehicle performance in real time via a display field that can monitor driver and engineers, so that efficient energy management is possible while driving.
Mature cooling system contributes to longevity
The Seat Cupra E-Racer relies on a tailor-made cooling system, which can cool the vehicle within 20 minutes with three independent cooling circuits.
“There are three independent cooling circuits, each element has its own temperature limit: The boundary area of the battery is 60 ° C, which the inverter at 90 ° C and that of the motor at 120 ° C.”- Xavier Serra, development leader of the SEAT CUPRA E-RACER
Now it is still true for the Cupra team to find out how to efficiently use the amount of energy in the vehicle to achieve good lap times. From Serra’s point of view, components and strategy go hand in hand and form a combination whose completion is provided for 2020 when the CUPRA E-Racer will compete for the new race series ETCR for the first time.
