Cummins progressing with lightweight downsized T2B2 diesel for pickup; 40% improvement in fuel economy over gasoline V8

Green Car Congress

At the US Department of Energy’s (DOE’s) Annual Merit Review meeting in Washington, DC last week, Michael Ruth from Cummins noted that the DOE program target for the project is a fuel economy (CAFE) target of 26 mpg (9.05 Cost of the new engine relative to gasoline baseline. Earlier post.). l/100 km) for a vehicle of that size.

ALTe Developing Series Plug-in Hybrid Powertrains for Conversion and OEM Applications

Green Car Congress

A Bloomfield, Michigan startup is developing light- and medium-duty series plug-in hybrid electric vehicle powertrain systems—initially as conversions, but ultimately extending to an OEM basis. In the Crown Victoria, the proof of concept powertrain conversion systems improve fuel economy from 80%-200% from the base 4.6L

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%

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. The study investigated the the WTW energy and emissions from the use of natural gas in CNGVs with a range of CNGV fuel economy and natural gas compressor efficiency.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

Manufacturers continue to optimize diesel emission controls, such as DOC, DPF and SCR, in order to promote uniform catalyst coating, improve NO x conversion efficiency, reduce back pressure on the engine, and reduce thermal mass. Better catalysts and urea dosing systems can achieve high NOx conversion during lower temperature operation.

Deloitte Survey finds only 4% of global consumers likely to be satisfied with current EVs despite increasing consideration and willingness to buy; higher ICE fuel economy reduces interest in EVs

Green Car Congress

Conversely, the survey reveals that improvements in fuel efficiency for gasoline and diesel vehicles reduce the appetite for electric vehicles. There is a clear disconnect between consumers’ expectations for electric vehicles and the actual capabilities and costs of technologies available in the market today.
