Digital Displacement® hydraulics - an enabling technology for hybrid vehicles

Digital Displacement® technology connects the high reliability and power density of hydraulics with the efficiency required for an effective hybrid system:

  • High efficiency
  • Fast control response
  • High power density
  • Simple materials used for construction - basically steel
  • Robust, long-life components

Hybrid Transmission

Series Hybrid

Artemis demonstrated its first full Digital Displacement® Hybrid Transmission in a BMW 530i, in May 2008.   Independent tests confirmed the car gave double the fuel economy in city driving compared to the same car with a six speed manual transmission.  Overall, including highway driving, the vehicle had 30% lower carbon dioxide emissions using the hydraulic series transmission.
