Fuel Economy Label: Updates
Fuel Economy Labels:
A Reliable Consumer Tool
The fuel economy label provides consumers with reliable and repeatable estimates of real-world fuel economy for national-average drivers and conditions allowing consumers to compare fuel economy across different car models.

EPA requires auto manufacturers to revise MPG (miles per gallon) values on fuel economy labels (window stickers) if relevant information becomes available that show that values are too high. EPA oversees the MPG values on fuel economy labels in a variety of ways including:
- Conducting independent testing on about 15% of vehicle models each year. This testing is done on pre-production vehicles provided by manufacturers.
- Testing in-use cars and trucks to confirm the fuel economy labels are accurate for post-production vehicles.
- Assessing information provided by consumer groups, the auto industry, and fueleconomy.gov to identify models for further testing.
If testing reveals that fuel economy labels are inaccurate, EPA will require manufacturers to update the MPG values to provide consumers with the most accurate information available. This page provides the information on EPA's fuel economy label updates. Updated values are also reflected on fueleconomy.gov.
BMW Updates Fuel Economy Values for 2014 Mini Cooper 3-door
During EPA fuel economy audit testing, the 2014 BMW Mini Cooper 3-Door was found to have values that differed from those submitted to EPA at the time of certification. Specifically, EPA conducted road-load audits of Mini vehicles produced by BMW in the 2014 model year. The Mini Cooper 3-door was found to have road-loads (i.e. aerodynamic drag, tire rolling resistance, and driveline friction) which exceeded EPA audit criteria when compared to the values originally reported by BMW at the time of certification. Both BMW and EPA performed emissions and fuel economy testing of the affected models using the road-loads determined in the production vehicle audit. While these vehicles were found to be in compliance with the emissions standards, the fuel economy label values were affected. The specific changes to fuel economy window stickers are listed in the table below.
Old Label Values | New Label Values | |||||||

Model | Eng | Transmission | Combined (mpg) | City (mpg) | Highway (mpg) | Combined (mpg) | City (mpg) | Highway (mpg) |

Mercedes Updates Fuel Economy Values for Two C300 4-Matic Vehicles
During EPA fuel economy audit testing, the Mercedes C300 4-matic was found to have values that differed from those submitted to EPA at the time of certification. With EPA oversight, Mercedes conducted new emissions and fuel economy testing, and EPA conducted its own testing at its National Vehicle and Fuel Emissions Laboratory in Ann Arbor, Michigan. As a result of the testing, EPA is requiring Mercedes to relabel the 2013 and 2014 C300 4-matic models with lower fuel economy values. The specific changes to fuel economy stickers are listed in the table below.

Ford Updates Fuel Economy Values for Six Vehicle Models
Ford recently alerted EPA that it had identified an error affecting fuel economy values for a number of their vehicles. Specifically, Ford discovered that it underestimated some of the real world factors, including aerodynamics and tire friction that are important inputs into fuel economy testing. EPA worked with Ford on an extensive re-testing program to correct the error, overseeing Ford's fuel economy tests, and also conducted independent testing at EPA's National Vehicle Fuel and Emissions Laboratory in Ann Arbor, Michigan to confirm the results. As a result of this testing, Ford is now relabeling six vehicle models. The specific changes to fuel economy stickers are listed in the table below.
