ZF has developed a pre-series electric drive that can run at up to 30,000 rpm, with a two-stage gearbox and an integrated motor, inverter and transmission. The company reports about 25% less installation space and weight than a 200-kW SELECT comparison drive, and aims to halve magnet use. Series production is targeted by 2030, but no customers, vehicle programs or specific efficiency figures have been disclosed.
ZF has developed a High Revolution Drive electric powertrain that runs at up to 30,000 rpm and is designed for 400- and 800-volt vehicle systems. The German supplier says the pre-series design delivers up to 200 kW while using about 25% less installation space and weighing about 25% less than a 200-kW SELECT drive used for comparison; ZF is targeting series production by 2030.
The system combines an electric machine, inverter and transmission in a 3-in-1 arrangement. ZF pairs the high-speed motor with a two-stage spur gear transmission with an approximately 18:1 ratio. The gearing is intended to convert the motor’s speed into the torque required at the wheels. ZF lists peak output at 200 kW and peak wheel torque at 3,500 Nm.
ZF’s comparison is with a SELECT drive rated at the same 200 kW and a maximum motor speed of 18,000 rpm. Against that reference, the supplier reports roughly 25% lower installation space and 25% lower weight for the High Revolution Drive. ZF also says it aims to reduce the drive’s magnet requirement by 50%; the source report does not provide a measured production-unit result for that target.
The company says efficiency remains at the level of the comparison drive, despite the higher speed and reduction gearing, but has not published specific efficiency figures. ZF identifies noise and vibration as engineering challenges at high rotational speeds and says the motor, gears, bearings and tooth geometry were developed together. It describes 30,000 rpm as a technical and economic “sweet spot” for this configuration.
Smaller Drives, Less Magnet Material
If the reported dimensions and weight reductions carry through to production, automakers could gain more flexibility when packaging electric powertrains. Lower drive mass and installation volume can be useful when designing vehicles around limited space, although ZF has not identified a model or quantified any vehicle-level range, cost or performance benefit.
The proposed 50% reduction in magnet requirement could also matter to manufacturers seeking to reduce material costs or exposure to particular raw materials and supply chains. That remains a target reported by ZF, not a verified result across a production program. The company’s statements on packaging and mass are likewise comparisons against one specified SELECT drive, not a claim that every competing drive would be larger or heavier.
The announcement also shows ZF’s attempt to distinguish its future e-drives through system design rather than power output alone. The concept uses a higher-speed motor and reduction gearing while retaining a stated 200-kW peak rating. Whether automakers see enough benefit to select it will depend on factors including efficiency, durability, cost, noise and vehicle integration, for which public details remain limited.

Built on ZF’s SELECT Platform
The High Revolution Drive is based on ZF’s modular SELECT platform, allowing the supplier to reuse existing components and technologies rather than create an entirely new modular system, according to the company. The architecture is aimed initially at the 150- to 200-kW segment, while ZF says it can be scaled to other power levels and supports both 400- and 800-volt systems.
The announcement comes as ZF reorganises its e-mobility business. The source report says the supplier decided in spring 2026, after a make-or-buy review, to continue developing and producing electric motors and inverters in-house. It also reports that the e-drive division faces cost pressure amid lower utilisation than originally expected. Those business conditions form part of the backdrop, but ZF has not said that the new drive will resolve the division’s financial challenges.
As of the November 6 report, the drive remained in the pre-series phase. ZF said it was in discussions with several automakers, but did not identify prospective customers, signed supply agreements or specific vehicle projects. Its stated production target is by 2030, rather than a confirmed start date.

Performance and Customers Undisclosed
ZF has not published specific efficiency values, test conditions or a detailed methodology for its comparison with the SELECT drive. The report also does not specify the drive’s continuous power, full operating range, durability results, production cost or the vehicle-level effects of the claimed packaging and weight reductions.
The magnet figure is described as a goal, and the supplier has not named the materials involved or explained how the reduction is measured. It is also unclear how the system’s noise and vibration performance compares with conventional drives under real-world operating conditions. ZF says the components were co-developed to address those issues, but detailed test results are not provided.
ZF has not named any of the automakers it says it is discussing the concept with, nor has it announced a customer contract or vehicle application. The 2030 production target may depend on development, validation and customer decisions; no firm production schedule or launch market has been disclosed.
From Pre-Series to Production
The next milestones are likely to include further development and validation, followed by decisions by potential automaker customers on whether to use the system in particular vehicles. ZF has not announced dates for those steps, technical test results or a named production partner.
Readers can look for updates on efficiency data, durability, noise and vibration, as well as evidence that the magnet and packaging targets can be met in a production-ready unit. ZF’s stated goal remains series production by 2030, but the company has not confirmed a specific launch date or vehicle program.
Key Questions
What is ZF’s High Revolution Drive?
It is a pre-series electric drive integrating an electric machine, inverter and transmission. ZF says the motor can reach up to 30,000 rpm and the system is designed for 400- and 800-volt architectures.
What power and torque does the drive provide?
ZF lists peak power of 200 kW and peak torque of 3,500 Nm at the wheel. The drive uses an approximately 18:1, two-stage spur gear transmission to reduce motor speed and deliver wheel torque.
How much smaller and lighter is it?
ZF reports about 25% less installation space and about 25% lower weight than its 200-kW SELECT drive, which has a maximum motor speed of 18,000 rpm. The figures are comparisons with that specific reference unit.
When could it enter production?
ZF says it aims to begin series production by 2030. The drive remains in pre-series development, and the company has not announced a confirmed start date, customer or vehicle application.
Has ZF confirmed the claimed efficiency and magnet savings?
No detailed efficiency figures have been published. ZF says efficiency remains at the level of its comparison drive and aims to halve magnet requirements, but the report does not provide test data or production validation for either statement.
