The Audi e-tron foil premieres in 2021 with a rare motor design for electric foils. Aerofoils, under the wing of Audi, set out to make the best premium divertug to complement the Audi e-tron series of electric vehicles. The surf has adopted important qualities of innovative technology, such as safety, eco-friendliness, automtion.
The efoil features many sensors to enable smart functions. Select your level and riding style and the system will help you control your speed and power consumption. The surf collects data on your rides and overall system performance, you can track your progress and technical information will be stored for service and early warning of potential malfunctions.
The hull, foil, and mast are designed thoroughly and from high-tech materials. Carbon fiber is strong, light, and stiff. You can feel the responsiveness to the slightest effort. Designers from Audi together with engineers from the aircraft industry took part in designing the hydrofoil.
The Audi e-tron foil is a fast, quiet, "green" electric foil. The battery features sensors to help the system work optimally, cost-effectively, and when it needs to give off maximum power. When designing the power system, the team paid special attention to safety. High-performance cells provide plenty of range with low weight. An optional radio module is built into the surf so you'll never lose contact with your Audi e-tron.
The Aerofoils team has taken a special approach to foil and motor design. Most electric foils are powered by propeller thrust, while the Audi e-tron features a jet motor, like in electric surfs. The closed design of the motor ensures safety so that the rider will not be able to hurt himself if he comes into contact with the open propeller. The compact motor hull and clever aerodynamics minimize water resistance, which increases range and helps the foil to confidently cut through the water. engineers managed to abandon the gearbox, which increased the reliability of the system and simplified maintenance. As the motor is on the same level as the wing, the Audi Surf can climb to a maximum mast height of 80 cm.
