THE 2023 MILEAGE REPORT: Miles per gallon gasoline equivalent
The top chart shows miles per gallon from mid-2001 through the end of 2023 for all seven cars in the dataset. The other chart focuses only on our current vehicles. We sold the Jetta in September 2012 and the Rio was totaled in an accident in February 2016. Our first 2013 Leaf was totaled in an accident in August 2019, and the nearly identical 2013 Leaf that replaced it was totaled in an accident a mere 34 days later in October 2019. We replaced it with yet another nearly identical 2013 Leaf, so here and throughout the rest of this year’s report all three 2013 Leafs are treated as a single vehicle for the sake of simplicity. We sold the C-Max in February 2022, and picked up the Model Y in March 2022.
Figures for the Jetta and Rio, both old-fashioned gasoline-burning internal-combustion engine cars, were recorded on a per-tank basis. Due to the more frequent, often daily nature of plug-in vehicle charging compared to gas station fill-ups, figures for the Leaf, C-Max, and Model Y are recorded on a weekly basis. Fuel economy for the Leaf, C-Max, and Model Y are shown as miles per gallon gasoline equivalent, or MPGe, an EPA metric that allows the energy consumption of plugin and non-plugin vehicles to be compared. The C-Max’s efficiency figures take into account both electricity and gasoline consumption.
The Model Y’s overall MPGe in 2023 was 123, up 1 percent from 2022. The weekly low and high MPGe were 111.2 and 156.7, respectively.
The Leaf’s overall MPGe in 2022 was 141, down 2.6 percent from 2022. The weekly low and high MPGe were 107.8 and 158.4, respectively.
