The Rotax E10 Mini is a fully electric powertrain specifically designed for youth competitive kart in the Mini category (age 10-12). Drugs 10,5 kW peak power, corresponding to the performance characteristics of the traditional Rotax 125 Mini MAX. The system has a dual battery configuration with 12kg lithium-ion twin batteries, providing about 20 minutes of continuous driving time with a fast 34-minute charging cycle (10%-80%).
The E10 Mini emphasizes simplicity, low maintenance and standardized performance, no fuel mixing, no carburetor maintenance and predictable operating costs. A unique feature "Pulsante Boost" adds strategic race elements providing 30% additional torque for 5 seconds intervals.
