Fueling and maintaining electric vehicles is about 40% cheaper than maintaining gasoline vehicles, according to a recent study by the U.S. Office of Energy Efficiency and Renewable Energy. The latest government study offers official proof that electric vehicles are cheaper to maintain than other vehicles, including hybrids.

The U.S. government operates the largest fleet of electric vehicles in the world, giving it plenty of data on maintenance and fueling. In the study, the government found that it spends less on maintenance on EVs, owing to the fewer parts in electric engines as compared to gasoline ones.

The study looked at four types of vehicles, comparing their maintenance and operational costs. It was found that the estimated scheduled maintenance cost for a light-duty battery electric vehicle (BEV) is $0.061 per mile while a traditional internal combustion engine vehicle (ICEV) costs about $0.101 per mile. The other options considered are plug-in hybrid electric vehicles and hybrid electric vehicles, which were also found to be cheaper than traditional gasoline vehicles at $0.090 to $0.094 per mile, respectively.

“The estimated scheduled maintenance cost for a light-duty battery-electric vehicle (BEV) totals 6.1 cents per mile, while a conventional internal combustion engine vehicle (ICEV) totals 10.1 cents per mile. A BEV lacks an ICEV’s engine oil, timing belt, oxygen sensor, spark plugs and more, and the maintenance costs associated with them,” the study explained. Although the per mile savings look small, they add up to millions of dollars saved per year.

For a long time, it has been known that electric vehicles are cheaper to maintain and run, the main reason being the number of moveable engine parts and the pricing models for gasoline as compared to electricity. An internal combustible engine vehicle has approximately 10,000 parts, while a battery-electric vehicle may have less than 10 parts. This means that fewer parts of the vehicle need servicing and as a result, less money is required.

This study provides the much-needed information to help those who have been hesitant to transition from traditional vehicles to electric ones.
