The Advanced Diesel Electric Powertrain (ADEPT) project was launched in 2013 to demonstrate the potential for 48V-based intelligent electrification in delivering full hybrid-scale fuel efficiency from a highly cost-effective package. The team was led by Ricardo and includes Ford Motor Company, Controlled Power Technologies (CPT), the European Advanced Lead Acid Battery Consortium (EALABC), Faurecia, and the University of Nottingham.

Customer Benefit

The ADEPT collaborative research programme targeted 15% reduction in CO2 through intelligent electrification at 48V, at a lower on-cost per g/CO2 than full hybrid. The current demonstrator vehicle has demonstrated CO2 reduction of 11% relative to baseline on the NEDC (New European Driving Cycle) and 6.5% on WLTP (Worldwide harmonized Light Vehicles Test Procedures), with further 2-4% benefit predicted from advanced thermal and lubrication improvements enabled though electrification. The current on-cost of the technology is 60€/gCO2/km, better than a full hybrid.


The project is based around a 1.5 litre diesel engine achieving Euro 6.1 emissions regulations in a Ford Focus.

ADEPT applies 48V mild-hybridisation to a diesel:

  • 1.5L diesel engine
  • 48V 12.5kW Belt Starter Generator
  • Low-cost advanced lead-carbon 48V battery pack
  • 48V Electric Ancillaries
