The ‘Spirit of Innovation’ officially became the world’s fastest all-electric vehicle in January 2022, when speeds of 387.4mph reached during test flights in November 2021 were officially verified by the Federation Aeronautique Internationale – breaking three separate world speed records. It was the result of a long-term partnership between Rolls-Royce, YASA and Electroflight – a British aviation energy storage specialist and Amorim’s customer on this project.
Electroflight designed the entire powertrain and integrated battery system for the Spirit of Innovation, using three YASA 750 R axial-flux electric motors and more than 6,000 Murata VTC6 18650 NCA cylindrical cells. They needed to find a material for the battery case that would not only be structurally robust, but would also be light and extremely fire resistant.
