41 C.F.R. § 102-34.60 How do we calculate the average fuel economy for our fleet?
Title 41 - Public Contracts and Property Management
(a) Due to the variety of motor vehicle configurations, you must take an average of all motor vehicles, by category (passenger automobiles or light truck) purchased and leased by your agency during the fiscal year. This calculation is the sum of passenger automobiles or light trucks that your executive agency purchases or leases from commercial sources divided by the sum of the fractions representing the number of motor vehicles of each category by model divided by the unadjusted city/highway mile-per-gallon ratings for that model, developed by the Environmental Protection Agency (EPA) for each fiscal year. The EPA mile-per-gallon rating for each motor vehicle make, model, and model year may be obtained from the: General Services Administration, Attn: FFA, Washington, DC 20406. (b) An example follows:
Light trucks: i. 600 light trucks acquired in a specific year. These are broken down into: A. 200 Six cylinder automatic transmission pick-up trucks, EPA rating: 24.3 mpg, plus B. 150 Six cylinder automatic transmission mini-vans, EPA rating 24.8 mpg, plus C. 150 Eight cylinder automatic transmission pick-up trucks, EPA rating: 20.4 mpg, plus D. 100 Eight cylinder automatic transmission cargo vans, EPA rating: 22.2 mpg. ii. Fleet average fuel economy for light trucks in this case is 23.0 mpg.
