eGen Flex™

eGen Flex™ electric hybrid provides revolutionary capabilities and fully electric propulsion for up to 10 miles depending upon duty-cycle, without the added infrastructure requirements of full EV. Our advanced technology provides a fully electric mode with geofencing capabilities when entering zero-emission zones or depots, eliminating emissions and reducing noise levels, specifically in highly populated areas.


  • Drive Unit

  • Inverter

  • Rechargeable Energy Storage System


Drive Unit

  • Multispeed gearbox
  • Fully integrated electric motors built into the gearbox
  • Same proven industry-leading reliability
  • Disconnect clutch added to enable disengaging input shaft from the engine
  • Provides propulsion while the engine is at zero speed, enabling full engine-off propulsion capability


  • Improved efficiency
  • Improved packaging – one-third the size and 50 lbs. lighter than inverter used in earlier generation electric hybrid systems
  • WEG cooling – no oil-coolant lines from the drive unit, reducing installation complexity and maintenance costs

Rechargeable Energy Storage System

  • Lithium Titanate (LTO) chemistry ideal for electric hybrid operation with constant recharging
  • Increased energy capacity – industry-leading 10-mile electric range capability
  • Battery design life of eight years
  • Faster charging than other chemistries
