Rotax E20

The Project E20 is the next step in the e-kart strategy of Rotax.

It was developed entirely by Rotax using the experience gained over the past years in E-racing. Rotax' new E-unit delivers next-level high performance lithium-ion battery capacity, drive time and boost function. 

The impressive power output and overall performance comes with reduced weight and more efficiency. The powertrain is equipped with a water-cooled motor and inverter, plus an internal vehicle control unit.
