Integrating a motor, gearing and power electronics into a compact, modular package that sits between a vehicle’s driven wheels creates a system that has come to be known as an e-axle. It is an increasingly attractive option for manufacturers of passenger cars, small commercial vehicles and trucks who want to develop hybrid and all-wheel-drive versions of existing products, while for developers of pure EVs they are a means of making the best use of the internal volume for extra battery capacity, passenger space or other selling points.
