Our premier class. Combustion powered by 100% renewable fuel.
Originally known as Petrol, this category was rebranded as EFuel starting from the VIII edition (2024/2025), reflecting the competition's commitment to sustainability through the use of synthetic and renewable fuels. Prototypes are developed around a 250cc 4-stroke internal combustion engine, inspired by the regulations of the Moto3 world championship.
In the latest edition (VIII MotoStudent, October 2025), the Basic Kit supplied by the organization included the KTM 250 SX-F engine, rims, and braking system. The rules are strict: it is completely forbidden to structurally alter the crankcase or the mounting points of this engine.
The real engineering challenge: The entire design relies on the manufacture of the chassis, swingarm, subframe, complete aerodynamics, telemetry, and intake/exhaust systems. Historically, this is where MotoMaqLab squeezes thermodynamics to the maximum, managing to extract every horsepower through injection map optimization and mechanical design of the highest precision.
