Rotax E10 Engine Package

ROTAX E10 is not just an electric kart engine – it's a complete concept defining the future of karting. Developed by ROTAX, a world-leading manufacturer of racing engines with over 100 years of experience, the E10 is built to meet a new generation of drivers and track owners who demand sustainability, performance and ease of use all in one package.

With a peak output of 10.5 kW, a boost function that temporarily increases power by 40–60%, and a completely silent operating mode, the E10 combines the thrill of racing with the future's demands on environment and noise level. This is the machine that makes it possible to run longer, without disruptive engine noise, oil spills or petrol fumes – perfect for indoor tracks, urban environments or noise-sensitive areas.

The E10 is also modular and flexible: in its base configuration with one battery, it's suited to the Bambini class (5 kW). By simply adding a second battery, the engine is upgraded to the Mini class (10.5 kW) – a smart, cost-effective solution that lets the system grow with the driver. No more engine swaps when changing class – just plug-and-play.

Technical highlights:

• Power: 5 kW (Bambini) / 10.5 kW (Mini)
• Boost button: 40–60% extra power for 5 seconds, available every 45 seconds
• Run time: approx. 20 minutes per charge
• Charging time (10–80%): 28 minutes (single battery), 34 minutes (dual)
• System voltage: 48 V
• Top speed: up to 110 km/h (with the right gearing)
• Protection class: IP67 – water- and dust-resistant
• HMI interface: Simple control with start button, charge status and drive mode
• Drive: Chain drive (type 219)
• Weight (without chassis): 27.7 kg (Bambini) / 40.5 kg (Mini)

For track owners and operators, the E10 offers several concrete benefits: longer opening hours thanks to silent operation, simpler maintenance with no oil changes or carburettor issues, and closer racing thanks to ROTAX Next Level Parity – where all competitors run with the same performance. Less time troubleshooting, more time for customer relations and business development.

For parents and young drivers, the E10 is an accessible, clean and safe way to step into the world of motorsport. No prior engine experience required – just start, drive and have fun.

ROTAX E10 is the kart engine of the future – silent, powerful, connected and ready to transform racing at its core.
