ICCT working paper highlights benefits of current and emerging light-duty diesel technology; “promising pathway for compliance”

Green Car Congress

The ICCT team—John German and Aaron Isenstadt—concluded that diesels have and will retain two significant advantages over gasoline engines: significantly better fuel economy and cargo hauling and towing ability. Meeting the 2025 standard will require an average improvement in fuel economy of about 4.1%

Ricardo to display functional integration prototype of ADEPT 48V “intelligent electrification” diesel

Green Car Congress

The supporting systems for electrical and vehicle integration include a 12V-48V DC-DC converter and a Ricardo hybrid supervisory controller. An effective limitation on downsizing, however, is the delivery of acceptable driveability characteristics and launch performance. 48V Diesel Fuel Efficiency'
