KleanDrive – Re-Power
KleanDrive and Alexander Dennis are developing modular electric powertrains to repower existing diesel buses into zero-emission vehicles under DRIVE35.
KleanDrive and Alexander Dennis are collaborating to develop a modular electric powertrain system that converts their existing diesel buses into fully electric, zero-emission vehicles. Rather than scrapping older vehicles, the project reuses their chassis and structure, fitting a new self-contained electric drive unit that includes batteries, motor, cooling, and control systems on a single frame.
The work will take place entirely in the UK, with the first demonstration vehicle and pilot manufacturing cell completed in 2026. This will show how the system can be built at scale using UK suppliers and a repeatable, high-quality process equalling that used in new-vehicle production.
Project highlights:
- The aim is to make fleet electrification faster, cheaper, and more sustainable, helping operators reduce emissions and operating costs while creating new skilled manufacturing jobs in the UK.
- This collaboration is about turning the buses we already have into the zero-emission vehicles we need, delivering environmental, economic, and social benefits much sooner than building entirely new fleets.
