ZF shifts EV transmission efficiency up a gear

ZF Project Engineer Volker Vogel checked that the Lausitzring test track ahead was clear and announced: “Now from stationary on full throttle.” From the rear of the prototype van came the almost instant and familiar whine of a very busy electric motor as the speed built. Then, the unexpected: A slight change in volume at 70 kph (44 mph) as the transmission shifted to a second gear. “It is only at prototype stage.”

Implicit in Vogel's words was the need to make allowances. But that was not necessary; as shifters go, this is a real smoothie.
