Why the fuel type changes the number
No exhaust, no emissions test and far fewer moving parts, which is why EVs post the highest pass rates of any fuel type. Tyres and suspension take the load instead, since they are heavier.
On the Mercedes-Benz B-Class specifically, electric is the strongest at 84.5%, and this electric version sits 9.3 points above the 75.2% model average.
What it means if you are buying one
The electric Mercedes-Benz B-Class is the stronger side of this model on MOT data. Still judge the individual car, but the fuel type is a mild point in its favour. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average electric Mercedes-Benz B-Class had covered 45,186 miles at test, against 78,400 for the diesel and 71,194 for the petrol. That is below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck.
Fuel type and mileage are tangled together: diesels are usually bought by higher-mileage drivers, so some of any gap between fuels is the miles rather than the engine. The per-year figures on the Mercedes-Benz B-Class page separate age from fuel if you want to isolate one.
