Using a parametric modeling approach, we evaluate economic and environmental life cycle
trade-offs of medium-duty electric trucks in comparison with nine non-electric technologies …

Inspired by the rapid development of charging-while-driving (CWD) technology, plans are
ongoing in government agencies worldwide for the development of electrified road freight …

This study presents a methodology for classifying road traffic energy efficiency. The
indicators defined discriminate the impact of the road vertical and horizontal alignments …

To determine the fuel economy and emissions of a vehicle using a chassis dynamometer,
the load to which the vehicle is subjected when it actually runs on a road, or the road load …

This research project compares laboratory-measured fuel economy of a medium-duty diesel
powered hydraulic hybrid vehicle drivetrain to both a conventional diesel drivetrain and a …

In order to improve the fuel economy of the heavy duty trucks at a highway driving condition,
the heavy duty hybrid trucks with new type of hybrid electric assist engine system were …

Emissions, fuel economy, and performance are determined over a light and a heavy driving
cycle designed to represent the vehicles in-use driving patterns. The vehicles are 2010 class …

In this paper, researchers at the National Renewable Energy Laboratory present the results
of simulation studies to evaluate potential fuel savings as a result of improvements to vehicle …

With ongoing concerns about the elevated levels of ambient air pollution in urban areas and
the contribution from heavy-duty diesel vehicles, hybrid electric vehicles are considered as a …

City cars are expected to be green and fuel saving. However, due to crowded urban traffic
they must move slower and thus less efficient. Vehicle efficiency has to be quantitatively …
