EVs and Plug-in Hybrids cost less to maintain than ICE vehicles. [1] Over 200k miles, ICE vehicles are about double the maintenance cost of EVs or Plug-in hybrids, and EVs are slightly more than Plug-in hybrids.

-At 50k miles; EVs $600, Plug-in $1,050, ICE $1,400.

-100k miles; EVs $2,000, Plug-ins $2,600, ICE $4,400.

-200k miles; EVs $6,300, Plug-ins $5,900, ICE $12,300.

EVs use about 30kWh to go 100 miles [2][3] and at the US national average for electricity [4], that would be about $6,250 to drive 200k miles. ICE vehicles vary but 35 mpg combined is pretty average [5] for compact cars. At the US national average for gasoline [6], that is $18,070 to drive 200k miles. Plug-in hybrids use about 29kWh to go 100 miles and about 48 mpg [7]. Just assuming 50/50 driving on gas or electric, that’s about $9,610 to drive 200k miles.

So maintenance and fuel cost over 200k miles would be roughly:

-EVs $12,552

-Plug-in Hybrids $15,510

-ICE $30,370

Nice calculations. 200k miles is 320,000 kilometers. Most vehicles are never driven that much before scrapping (or maybe they're exported to Africa?)

In the US, people keep new cars for an average of 8.4 years [1], and the average working age adult (age 20-54) drives about 15,200 miles per year [2]. That is over 127,000 miles, and that is average. Obviously if you are someone that trades in their car every 2 years, long term costs aren’t important to you. But lots of people keep their cars over 100k miles, and plenty keep their cars out to 200k. I included 50k and 100k on the maintenance prices, and fuel costs just have to be divided in half for 100k. At basically any distance, EVs and plug-ins are significantly cheaper to maintain and fuel than ICE vehicles.

So maintenance and fuel cost over 100k miles would be roughly:

-EVs $5,125

-Plug-in Hybrids $7,405

-ICE $13,435
