ZF Unveils 30,000 RPM Electric Drive for Cars
The compact three-in-one High Revolution Drive delivers 200 kW and 3,500 Nm in a unit nearly 25% smaller than a comparable SELECT drive.
Updated on Nov. 6, 2026 in Electric Vehicles
ZF has developed the High Revolution Drive, a compact three-in-one electric drive system that combines an electric motor, power electronics and transmission and reaches speeds of up to 30,000 rpm. The presented version delivers a peak output of 200 kW and peak wheel torque of 3,500 Nm.
Why it matters
Higher motor speed reduces the torque the electric motor must produce at a given power output, which allows a smaller and lighter design with less magnet material. The drive is aimed at high-volume passenger cars needing roughly 150 to 200 kW.
The unit uses a two-stage spur gear transmission with a ratio of approximately 18:1 and reaches nearly 93% drive system efficiency. It supports 400-volt and 800-volt vehicle platforms.
The players
ZF
ZF is a German automotive supplier known for transmissions, driveline and chassis technologies, and the developer of the modular SELECT electric drive platform.
The details
The High Revolution Drive integrates the motor, power electronics and transmission into one unit and treats the motor, gearing, bearings and gear-tooth geometry as a single system to manage noise, vibration and durability. It is being developed as a variant of ZF's modular SELECT platform to reduce development effort.
Roadmap
The High Revolution Drive extends ZF's modular SELECT platform by raising motor speed to 30,000 rpm, a route to smaller and lighter electric drives. It reflects the broader industry push to cut magnet content and packaging size as electric cars move toward high-volume passenger models.
Smaller, lighter drive units could eventually free up cabin and underbody space and lower vehicle weight in future electric cars. The article does not indicate when such vehicles will reach showrooms or what they will cost.
The takeaway
Higher-speed motors are becoming a practical way to shrink electric drives without sacrificing output. Watch for which automakers adopt the High Revolution Drive as its SELECT-based variant moves toward production.
