Steve Belvins, Head of Engineering, Ricardo Performance Products
Virtual Simulation Event 2022

Steve Blevins, presents a brief history of Formula E cars. He explains how different Series Regulations influenced the final transmission concept and design, and how different transmission layouts were used in recent years (Seasons 5 and 6).

Steve shows how SABR and SABR-Gear were used to design the gearbox and to optimise it in terms of component mass, durability and vibration. SABR was used to predict the efficiency of the gearbox at all operating speeds and torques, to ensure the transmission was as efficient as possible. The predicted efficiencies were correlated with measured test-rig data.

All of these aspects have even higher focus for Formula E performance due the limited energy provided by batteries compared with using fossil fuels.
