About Proton Cars
Proton ranks 68th out of 70 car makes in our data (those with at least 1,000 MOT tests) by average MOT pass rate, at 70%. That's 15 points below the 85% average across all models in our data, so Proton owners should budget a bit more for maintenance.
With 9 models across 15 years of data (1998 to 2012), there's a narrow spread of just 1 percentage points between models, meaning Proton reliability is fairly consistent across the range.
Most and Least Reliable Proton Models
The Gen-2 leads the range with a 66% average pass rate from 1,027 tests. At the other end, the Savvy has the lowest at 65%. A notable proportion of Proton models have pass rates below 70%, so researching specific models before buying is particularly important.
Proton Fuel Types
Proton models in our data come in 9 petrol variants (each model counted once, under the fuel type recorded for most of its tests). The range is predominantly petrol-powered.
Estimated Running Costs
