Hybrid against the other Mercedes-Benz C versions

Why the fuel type changes the number

Hybrids sidestep most emissions failures and tend to do lighter urban miles, though the extra weight tells on tyres and brakes.

On the Mercedes-Benz C specifically, hybrid is the strongest at 87.6%, and this hybrid version sits 9.6 points above the 78% model average.

What it means if you are buying one

The hybrid Mercedes-Benz C 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. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.

Mileage is part of the answer

The average hybrid Mercedes-Benz C had covered 66,318 miles at test, against 95,767 for the diesel and 76,080 for the petrol. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.

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 C page separate age from fuel if you want to isolate one.
