2019 Ram drops weight, gains 48V eTorque mild hybrid system

Green Car Congress

FCA pulled the wraps off the new 2019 Ram 1500 at the Detroit Auto Show. The eTorque mild hybrid system is one of several changes made to the powertrains for the 2019 Ram 1500. A cooled exhaust gas recirculation (EGR) system enables improved fuel economy and emissions performance at higher loads. liter HEMI V-8 configurations.

NREL: zero-emissions medium- and heavy-duty vehicles will reach cost-parity with diesel vehicles by 2035

Green Car Congress

Further, assuming economics drive adoption, the study finds that ZEV sales could reach 42% of all MD/HD trucks by 2030, reflecting lower combined vehicle purchase and operating costs (using real-world payback periods). BEVs tend to become cost-competitive for smaller trucks before 2030 and for short-haul (.

UCSD, South 8 team report improved liquefied-gas electrolytes for Li-metal batteries

Green Car Congress

Improvements to a class of battery electrolyte first introduced in 2017—liquefied gas electrolytes—could pave the way to replacing the graphite anode with a lithium-metal anode. Meng and colleagues’ approach was to switch to a more compatible electrolyte, called liquefied gas electrolytes. —Yang et al.

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

Green Car Congress

CO 2 and NO x certification test data for heavy-duty diesel engines certified from 2002 through 2019. Source of data: US EPA (2019). While the cost of new heavy-duty trucks has increased at approximately 1% per year, the cost of emission controls has come down, representing a lower percentage of the cost of a new truck.

IEA: Decisive action by governments is critical to unlock growth for low-carbon hydrogen

Green Car Congress

Currently, global production of low-carbon hydrogen is minimal, its cost is not yet competitive, and its use in promising sectors such as industry and transport remains limited—but there are encouraging signs that it is on the cusp of significant cost declines and widespread global growth, according the IEA’s Global Hydrogen Review 2021.
