4E Powertrain Test Cell

Millbrook's 4E Powertrain Test Cell is ideally suited to advanced development of hybrid powertrains, transmissions and stability control strategies. It can be used to test laid-out powertrains and full vehicles.


  • IC or hybrid emissions development, including simulation of real world and Regulated cycles
  • Test of powertrain with a virtual battery using the battery simulator
  • Powertrain control strategy development
  • Development of ABS and traction control systems using fully integrated tyre slip models
  • Mule use of components to simulate future vehicles
  • Condensed testing on a rig as opposed to track- or road-based testing
  • Highly repeatable measurement of fuel economy, emissions and energy consumption
