Almost a year after Triumph Motorcycles first pulled the covers off its Project TE-1 electric powertrain prototype, the company has unveiled the Project TE-1 prototype demonstrator. Those drawings and sketches have turned into a working electric motorcycle!

The unique collaboration between Triumph Motorcycles, Williams Advanced Engineering, Integral Powertrain Ltd, and WMG at the University of Warwick funded by the Office for Zero-Emission Vehicles through Innovate UK, was set up to create ground-breaking developments in specialist electric motorcycle engineering and innovative integrated technology design.

Phase 3

Phase 3 of the TE-1 project has now reached its completion, with the final build of the prototype demonstrator. Integrating for the first time all of the latest and final innovations from the project partner workstreams, the prototype demonstrator features:

–       Triumph: final chassis, including frame, rear sub-frame, cockpit, panels and wheels, final drive system including transmission and Gates Carbon belt drive, electronics, Öhlins USD cartridge forks, unique prototype Öhlins RSU, Brembo M50 monobloc calipers, and Triumph motorcycle control software

–       Williams Advanced Engineering: final iteration of prototype WAE battery pack incorporating dedicated cell packaging for optimum centre of gravity, vehicle control unit, DCDC converter, integrated cooling, charge port, and styled carbon covers

–       Integral Powertrain: final prototype powertrain with scalable integrated inverter and combined motor with silicon carbide switching technology and integrated cooling

–       WMG, University of Warwick: final pre-live trial simulation completed, with all results indicating that the project is on course to deliver the intended performance and durability outcomes

Phase 4

With the completion of the prototype demonstrator, the full live testing phase of the TE-1 project can now begin (phase 4). Over the next 6 months the prototype demonstrator will undertake an extensive live testing programme within Triumph’s state-of-the-art facilities, which will encompass:

Rolling road testing – core functional assessment to include:

  • Throttle calibration
  • Powertrain performance mapping
  • Power and torque output
  • Range and battery consumption assessment
  • Rider mode development
  • Software functionality validation
  • Thermal optimisation

Track testing – encompassing dynamic rider assessment to include:

  • Handling
  • Acceleration
  • Braking and braking regeneration strategy
  • Traction control
  • Front wheel lift control

At the completion of the live testing phase, estimated to be Summer 2022, the prototype demonstrator will be updated with its final body panels and paint scheme, in preparation for active track demonstration, and media engagement. At this time, the full results of the project including the final specifications and testing outcomes will be published.
