Recent data from the Driver and Vehicle Standards Agency (DVSA) reveals notable differences in MOT success rates between high-mileage petrol and electric vehicles (EVs). Vehicles that have covered between 90,000 and 120,000 miles show that EVs are approximately 25 per cent less likely to fail their MOTs than petrol models.
For cars exceeding 120,000 miles, the failure rate stood at 16 per cent for electric vehicles, compared to 23.5 per cent for their petrol equivalents. The analysis was conducted by the consultancy New AutoMotive on behalf of the British Vehicle Rental and Leasing Association (BVRLA).
Toby Poston, chief executive of the BVRLA, emphasised that this data invites a shift in perspective towards second-hand electric cars. He noted that while MOT tests assess essential aspects of roadworthiness such as brakes, tyres, suspension, steering, and lights, they do not evaluate battery health, degradation, or charging functionality.

He stated: “Mileage has traditionally been a key factor for buyers assessing used cars, often leading to concerns once vehicles surpass 60,000 or 70,000 miles. However, our research suggests it’s time to reconsider these assumptions for electric vehicles.”
Poston added that many EVs entering the used car market have previously served in company and leasing fleets, accumulating significant mileage. “This data indicates that mileage alone should not deter consumers. A well-maintained, high-mileage electric car can be a highly durable and reliable option.”
He highlighted the importance of consumer confidence in the used electric car market, noting: “The second-hand market is pivotal in making the transition to electric vehicles accessible to millions. Ensuring buyers trust these cars is vital for fostering a robust and affordable EV market.”
Ben Nelmes, chief executive of New AutoMotive, described the findings as “compelling evidence for prospective used EV buyers”. He explained, “High mileage does not necessarily equate to poor condition as traditionally believed. The simplicity of electric drivetrains confers increasing advantages as vehicles accrue miles.”
