High-Mileage EVs Pass UK MOT Tests More Often Than Petrol Cars, Study Finds

An analysis of 47.4 million UK MOT records found that among 3- to 8-year-old cars with 90,000–120,000 miles, 16.5% of EVs failed versus 22.1% of petrol cars. EV failure rates plateau near 60,000 miles, while petrol failure rates keep rising.

• 90,000–120,000 miles: 16.5% EV failures vs 22.1% petrol
• Above 120,000 miles: 16.0% EV failures vs 23.5% petrol
• At 20,000–40,000 miles the gap is negligible: 12.0% vs 11.7%
• MOT does not check battery capacity or range
