Lightning Repower:

Zero Emission City Transit Bus Electric Repower

The Lightning City Bus Repower solution is a great way to extend the life of older buses by replacing their diesel or CNG engines with clean, quiet battery-electric powertrains. Much less expensive than purchasing a new electric bus, and with a much shorter lead time from order to deployment, the Lightning Repower solution is an ideal way to convert your aging diesel or CNG fleet to electric. With some jurisdictions (such as the State of California) requiring city buses to be zero-emissions vehicles in the relatively near future, we can provide the lowest-cost path to meeting this requirement.


We use the highest-quality components available, including thermally-managed batteries which deliver the best range, efficiency and lifetime of any batteries in the market.

  • Battery-electric vehicle
  • Fast, smooth, and quiet
  • Zero on-road emissions

Analytics• Preventive maintenance • Range analysis • Driver behavior • Charger management

* All-electric range can vary depending on route or drivecycle, environmental conditions, vehicle or equipment configurations, and driver behavior.

** Payload and Passenger capacity can vary and greatly depend on vehicle wheelbase, seating configuration, and other characteristics or features as delivered by the OEM or chassis manufacturer. Equipment added to the base chassis by aftermarket upfitters or equipment installers could also affect Payload and Passenger Capacity.
