Performance

Optimised Performance

  • Pioneering new designs & incorporating new technologies in road & race engines
  • Experience in whole powertrain integration and design
  • A track record of developing high and low volume production engines from concept to production
  • Understanding the impact and requirements of the engine on the vehicle
  • Expertise in extending the life and increase volume of existing engines whilst adapting to changing market and legislative requirements

Range Extender Programs

  • Design & development of small, lightweight, efficient Range Extender engines, that are optimised to a variety of series hybrid applications
  • Integrated engine and “gen-set” control system
  • Designed to use either an integrated generator or any alternative externally supplied generator
