The objective of this analysis is to statistically investigate the association of primary fuel tailpipe carbon dioxide emissions in grams per mile to annual primary-fuel petroleum consumption in barrels after controlling for combined miles-per-gallon for the primary fuel type, vehicle manufacturer, make, engine displacement, engine cylinders, combined luggage and passenger volume in cubic feet, vehicle type, transmission type, and primary fuel type.
- Annual fuel costs shown in 1997-2014 Fuel Economy Guides are based on fuel prices when the guide was originally printed.
- 1 barrel = 42 gallons. Petroleum consumption is estimated using the Department of Energy's GREET model and includes petroleum consumed from production and refining to distribution and final use. Vehicle manufacture is excluded.
- The MPG estimates for all 1985-2007 model year vehicles and some 2011-2016 model year vehicles have been updated. Learn More
- Unrounded MPG values are not available for some vehicles.
- This field is only used for blended PHEV vehicles.
- For model year 2013 and beyond, tailpipe CO2 is based on EPA tests. For previous model years, CO2 is estimated using an EPA emission factor. -1 = Not Available.
- For PHEVs this is the charge depleting range.
- Annual fuel cost is based on 15,000 miles, 55% city driving, and the price of fuel used by the vehicle.
- Interior volume dimensions are not required for two-seater passenger cars or any vehicle classified as truck which includes vans, pickups, special purpose vehicles, minivan and sport utility vehicles.
- Fuel prices for gasoline and diesel fuel are from the Energy Information Administration and are usually updated weekly.
- Fuel prices for E85, LPG, and CNG are from the Office of Energy Efficiency and Renewable Energy's Alternative Fuel Price Report and are updated quarterly.
- For electric and CNG vehicles this number is MPGe (gasoline equivalent miles per gallon).
