PART 538--MANUFACTURING INCENTIVES FOR ALTERNATIVE FUEL VEHICLES--Table of Contents
 
Sec. 538.6  Measurement of driving range.

    The driving range of a passenger automobile model type not using 
electricity as an alternative fuel is determined by multiplying the 
combined EPA urban/highway fuel economy rating when operating on the 
alternative fuel, by the nominal usable fuel tank capacity (in gallons), 
of the fuel tank containing the alternative fuel. The combined EPA 
urban/highway fuel economy rating is the value determined by the 
procedures established by the Administrator of the EPA under 49 U.S.C. 
32904 and set forth in 40 CFR part 600. The driving range of a passenger 
automobile model type using electricity as an alternative fuel is 
determined by operating the vehicle in the electric-only mode of 
operation through the EPA urban cycle on its nominal storage capacity of 
electricity and the EPA highway cycle on its nominal storage capacity of 
electricity. Passenger automobile types using electricity as an 
alternative fuel that have completed the EPA urban cycle after 
recharging and the EPA highway cycle after recharging shall be deemed to 
have met the minimum range requirement.
