Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

First, it considers the performance of both mature and novel hydrogen production processes, multiple electricity generation pathways and several alternative drivetrains. Third, the analysis offers a novel comparison of drivetrain and energy carrier production pathways based on natural resource categories.

Argonne study finds BEVs can have lowest scheduled maintenance costs, but highest cost of driving

Green Car Congress

The study considers five different powertrains (internal combustion engine, hybrid-electric, plug-in hybrid-electric, fuel-cell-electric, and battery-electric) and 12 cost components (purchase cost, depreciation, financing, fuel, insurance, maintenance, repair, taxes, registration fees, tolls and parking, payload capacity and labor).

U. of Wisconsin RCCI combustion work progressing; modeled 53% gross indicated efficiency in a light-duty engine could result in 2x fuel savings compared to SI gasoline

Green Car Congress

The team has modeled a 53% gross indicated efficiency for the improved light-duty engine. In a single-cylinder heavy-duty research engine fueled with gasoline and diesel, RCCI delivered near zero NO x and soot and peak gross thermal efficiency of 56%; fueling with E85 and diesel resulted in an indicated efficiency of 59%.

Two case studies outline how Houston and Loveland are saving money with EVs in their fleets

Green Car Congress

Loveland is now aiming to convert all of its light-duty fleet vehicles that work within a close distance of the city to EVs. Its efforts to incorporate alternative fuel vehicles (AFVs) into its fleet began in 2002 with an initial purchase of hybrid electric vehicles (HEVs), mainly the Toyota Prius and Ford Escape hybrid.
