Final testing confirms ADEPT 48V diesel hybrid reduces fuel consumption 10-12% at low incremental cost

September 13, 2016

The three-year ADEPT (advanced diesel-electric powertrain) project (earlier post) in the UK set the target of developing and validating a range of advanced mild hybrid technologies with 48V “intelligent electrification” utilizing an advanced lead carbon battery. These have been applied to a Ford Focus project demonstrator which, for the first time, will be made available for public ride and drive evaluation by delegates at the Low Carbon Vehicle event (LCV2016), at Millbrook, UK.

Final testing has confirmed ADEPT’s key achievement of 10-12% reduction in fuel consumption (NEDC)—equivalent to sub-80g/km of CO2 emissions. According to the latest updated analysis of the potential cost of production implementation of ADEPT—conducted independently by Ricardo—the system would represent an incremental cost of in the region of €60 per gram/km of CO2 reduction. This is a result that makes the ADEPT powertrain architecture very competitive with other fuel economy solutions such as full hybridization, where costs of implementation can be significantly higher.

Audi developing electromechanical rotary dampers; potential for energy recuperation from suspension; 48V

August 10, 2016

Audi is developing a prototype electromechanical rotary dampening system called “eROT,” in which electromechanical rotary dampers replace the hydraulic dampers used today for an even more comfortable ride. The eROT system also offers the potential for energy recuperation from the suspension.

Every pothole, bump, and curve in the road induces kinetic energy during compression and rebound of the car’s suspension, observes Dr.-Ing. Stefan Knirsch, Board Member for Technical Development at AUDI AG. “Today’s dampers absorb this energy, which is lost in the form of heat. With the new electromechanical damper system in the 48-volt electrical system, we put this energy to use. It also presents us and our customers with entirely new possibilities for adjusting the suspension.
