Vehicle Drive Technology


As part of an electric tracked vehicle propulsion system, E-X-Drive® offers a lighter, more compact and efficient solution compared with conventional mechanical transmission systems.

E-X-Drive® combines electrical and mechanical components in a novel configuration that is efficiently packaged, incorporates mechanical regenerative transfer of steering power, range-shift mechanisms, and permanent magnet motor technology. E-X-Drive® is a demonstrated and low risk solution, with low stress levels in the motors, gears, shafts and bearing components.

Using E-X-Drive® as part of an electric propulsion system offers the opportunity for innovative tracked vehicle configurations founded on a fundamental shift in platform design trade space options. Not only is an E-X-Drive®-based transmission package smaller and lighter than comparable conventional transmissions it also lends itself to novel vehicle layouts to improve survivability, agility, and mission success.

Key performance advantages

  • Increased automotive performance and mobility
  • Full torque from standstill
  • High burst acceleration with Improved fuel efficiency
  • Engine downsizing and speed optimisation
  • Energy storage to allow load-levelling, regenerative braking, and silent watch capability
  • Flexibility in powertrain layout – whether a decentralised system or a consolidated power pack
