Fuel savings
The study shows that a typical EV owner who does most of their fueling at home can expect to save an average of $800 to $1,000 a year on fueling costs over an equivalent gasoline-powered car.
Maintenance and repair
The study also found that maintenance and repair costs for EVs are significantly lower over the life of the vehicle—about half—than for gasoline-powered vehicles, which require regular fluid changes and are more mechanically complex. The average dollar savings over the lifetime of the vehicle is about $4,600.
Depreciation
CR’s analysts also found that newer long-range EVs are holding their value as well as or better than their traditional gasoline-powered counterparts as most new models now can be relied on to travel more than 200 miles on a single full charge. As with traditional gasoline-powered vehicles, not all EVs will lose value at the same rate as they age. Class, features, and the reputation of the vehicle’s manufacturer all have an impact on depreciation.
