Stock Average On-Road Fuel Economy

See also: Results View, New Vehicle Rated Fuel Economy
Result Type: Transport

This results category displays the stock average on-road fuel economy (in miles per gallon) for all vehicles that exist in each year.  Results can be shown organized by branch, scenario, year and region (in multi-regional areas).  

This category is only available for those branches where you are conducting a transport analysis. To set up a transport analysis, go to the Methodology tab on the Properties screen for each applicable technology branch.

The data you enter for new vehicle rated fuel economy is combined with the fuel economy degradation profile data and processed in LEAP's stock turnover calculations to yield the stock average rated fuel economy. Finally, this value is multiplied by the fuel economy correction factor to yield the stock average on-road fuel economy result.

The Fuel Economy Correction Factor variable is primarily useful when modeling U.S. vehicles in which the data on fuel economy provided by the Federal Government reflects a level of fuel economy that can be achieved in laboratory tests. Typically this value is higher than real-world levels of fuel economy that can be achieved on the road. A correction factor of about 0.8 is generally used to convert from "rated" to "on-road" fuel economies. Keep the default correction factor of 1.0 if your original fuel economy data reflects on-road conditions.
