50/100Mixed fit
on a balanced view of all values
Fuel and electricity cost a year: Poor. The EPA estimates $3,850 to $5,050 a year in diesel across its 4 configurations, median $4,000, at 19 to 25 mpg combined. That assumes 15,000 miles a year with 55 per cent city driving at the fuel prices behind the EPA's figures in this file. Scored against the cheapest to run on this list ($600 a year scores 100; twice that scores 50). source↗ 2026-10
