2021 Mercedes-Benz G-Class: petrol or diesel?

Petrol, diesel and hybrid versions go wrong in different ways, so each has its own figures from the MOTs these cars had during 2023–2025. Pick the one you’re looking at: the fuel is on the logbook and in the car’s MOT history.

Petrol 92% pass first time (all 2021 cars: 87%) Nothing stands out above the usual rate 671 MOTsSee the petrol guide › Diesel 92% pass first time (all 2021 cars: 87%) Nothing stands out above the usual rate 370 MOTsSee the diesel guide ›

Hybrid versions had too few MOTs for figures of their own, or weren’t sold.
