EDGE7
// Better battery, better car
In 2015 we will start with the EDGE7, a further development and improvement of our previous electric car. A lot of attention has been paid to the battery pack this season in order to again guarantee high and reliable performance, which can now boast both an energy content of 6.2kWh and a nominal voltage of 310.8V. In the area of power electronics, a weight saving of 50% was achieved compared to last year. The monocoque has also been lightened by a further kilo thanks to new packaging.
