Gearbox maker ZF has built an electric drive system that would instantly improve almost any EV on the market.
Besides supplying an 8-speed gearbox to the entire BMW lineup, including the M models, ZF is also known to provide transmissions to other companies like Lamborghini and Porsche, making it the world's leading gearbox supplier.
But the German company has introduced a different product as a follow-up to its aim of becoming a one-stop shop for EV motor architecture.
ZF has showcased an electric vehicle concept called EVbeat. The concept vehicle is based on the Porsche Taycan and comes equipped with the German firm's compact and lightweight 800-volt motor called EVSys800 and its thermal management system. The result is an EV that performs better than OEMs – think of it as a performance tune in the age of electrification.

At the heart of the EVbeat lies the EVSys800 – a modular 800-volt drive that produces a peak output of 369 horsepower, with a continuous output rated at 276 hp or 75 percent of its maximum power. It also sends a mind-blowing 3,835 lb-ft of torque to the rear axle – more torque than the Mercedes-Benz Vision One-Eleven concept, which makes up to 2,360 lb-ft.
“Our goal was to make this drive as compact and lightweight as possible while maintaining high driving dynamics and increasing efficiency in real-world operation. In terms of torque density, we are at the top of the podium when we compare ourselves with e-drives for passenger cars currently available on the market,” said Dr. Otmar Scharrer, Head of Development for Electric Driveline Systems at ZF.

ZF boasts that the EVSys800 is compact and lightweight, making it compatible with many cars without compromising overall weight and performance. Its cooling system involves circulating oil around the parts that get hot during operation, while the patented 'Braided Winding' saves space and reduces the amount of copper needed.
ZF still believes in transmissions for EVs, so it introduces a new coaxial reduction gearbox that transmits the drive forces of the electric motor via two planetary gear sets. Besides providing a desired final drive ratio, it reduces weight and installation space requirements without compromising efficiency and cabin NVH limits.
“With this system, we can perfectly meet the main requirements of our customers – namely efficiency, performance, and costs,” said Dr. Scharrer.

ZF has also introduced a thermal management system called TherMaS to extend the EV's range. According to the company, TherMaS uses a propane-based 800-volt heat pump and a central refrigerant circuit to reduce weight, energy consumption, and space requirements, resulting in improved cooling performance and extended range even in demanding winter conditions.
ZF also developed powertrain software that “learns” optimal thermal operating points based on driving profiles, enhancing efficiency and adapting to individual driving behaviors.
Will we see the EVSys800 in production EVs in the future? Most likely, plus ZF said that its latest EV drive tech will hit the market in 2026. Coincidentally, Porsche is developing hotter Taycan versions, so there's that.
