Because of this, the 50-70% efficiency of hydrogen production has to be combined with the vehicle efficiency to yield net efficiency.

There is currently no agreed method of comparing electric vehicle efficiency to heat engine (fossil fuel) vehicle efficiency, but typical emissions and thermal energy consumption can be compared.

In addition to the CAFE program, the U.S. government has tried to encourage better vehicle efficiency through tax policy.

The engine electronic management and 3 valves per cylinder, with the optional Top Brake system to improve vehicle efficiency and durability of the brake system.

In other words, it could one day make lightweight material to improve vehicle efficiency while still offering many of steel's traditional benefits.

Nick Rothman has been involved in the growing alternative transportation since 1995 specializing in vehicle efficiency and advanced battery technology.

This revenue decline is partly due to improved vehicle efficiency and the growth of plug-in electric vehicles.

Software, depending on its capabilities, allows functions such as driver and vehicle profiling, trip profiling, dispatch, vehicle efficiency, etc.

Weight-specific efficiency (efficiency per unit weight) may be stated for freight, and passenger-specific efficiency (vehicle efficiency per passenger).
