“EVs Are Less Likely to Fail the MOT. Even With 100,000+ Miles” study finds.
BVRLA and New Automotive analysed 47.4 million MOT tests and found that at lower mileages, EVs and petrol cars perform remarkably similarly.
At around 20–40,000 miles, both are failing at roughly 12%.
But once the mileage gets above about 60,000 miles, the curves start to separate.
At 90–120,000 miles:
🔋 EVs: 16.5% failed
⛽ Petrol: 22.1% failed
That makes the high-mileage EV around 25% less likely to fail its MOT.
And above 120,000 miles, the gap gets bigger still:
🔋 EV: 16%
⛽ Petrol: 23.5%
So that idea that a 100,000-mile EV is automatically a gamble? Well, the MOT data really doesn’t support it. (Neither does battery health stats)
Obviously, an MOT doesn’t tell you battery health, but when it comes to the stuff an MOT actually measures, the high-mileage EVs are doing rather well.
