As commercial vehicles become increasingly electrified, manufacturers face a growing challenge: delivering higher performance while preserving valuable space for batteries, payload, and vehicle integration. Discover how Sonceboz addresses this challenge with UltraDrive, our next-generation central traction drive designed to maximize power density while minimizing size and weight.

Combining deep cooling technology with an innovative all-in-one architecture, UltraDrive enables vehicle manufacturers to rethink drivetrain integration without compromising performance.


Delivering 300 kW, 3,000 Nm, and an industry-leading 30 Nm/kg, UltraDrive achieves up to 50% lower weight and volume compared with conventional solutions. Its high-power density eliminates the need for a gearbox while advanced deep cooling technology maintains outstanding efficiency throughout the drive cycle. Designed without heavy rare earth materials, UltraDrive also supports a more sustainable and resilient supply chain.

Beyond a new traction drive, UltraDrive reflects Sonceboz’s strategic evolution toward Fluidtronics. By combining decades of expertise in mechatronics with advanced thermal management technologies, including ePumps, eCompressors, eFans, and eValves, we are developing integrated systems that address the growing cooling demands of next-generation high-power electric vehicles.

The result is more than a compact drive system. It is a smarter approach to electrification, helping you create more efficient commercial vehicles while unlocking valuable space for what matters most.
