$0.03/mile for BEV/PHEV vs. $0.06/mile for ICEs.
. . . Consumer Reports (CR) analyzed its 2019 and 2020 reliability survey data for many thousands of electric and gas-powered vehicles, and found that drivers of electric vehicles are saving an average of 50% on maintenance and repair over the life of a vehicle compared to owners of gas-powered vehicles. . . .
These findings on maintenance and repair costs are part of an upcoming white paper by Consumer Reports that compares costs of ownership for electric and gas-powered vehicles. The full white paper will be published in the coming weeks. For this report, ‘vehicle lifetime’ was defined as 200,000 miles. . . .
From GCR, same story:
. . . Perhaps even more surprising among CR’s findings is that plug-in hybrids cost less to maintain and repair than conventional gasoline vehicles—actually undercutting EVs in those costs after passing 100,000 miles. . . .
Consumer Reports doesn’t offer a reason for PHEVs’ advantage. Perhaps there is a sweet spot to be discussed in how the electrified components avoid wear to the traditional powertrain items—and, perhaps, extend the life of items like braking systems through regenerative braking. Or perhaps the repairs and maintenance simply cost more for EVs when needed. . . .
CR notes that its sample size of PHEVs and EVs with more than 100,000 miles was small—with the EVs mostly including early versions of the Nissan Leaf and Tesla Model S. With a total of 200 PHEV vehicles that have more than 100,000 miles, it also likely didn’t have a sample set that represented all the different layouts for these widely varied vehicles. . . .
