As electric vehicles (EVs) become more common across the UK, many drivers are comparing them with traditional petrol cars not just in terms of fuel efficiency, but also MOT performance and long-term maintenance costs. Understanding the differences between electric vs petrol vehicles can help drivers make more informed decisions about ownership, budgeting, and reliability.

MOT Failure Trends in Petrol Vehicles

Petrol cars have been subject to MOT tests for decades, and their failure patterns are well established. Common issues include exhaust emissions, brake wear, suspension faults, and tyre tread problems. As these cars rely on combustion engines, there are more moving parts subject to wear and tear, increasing the likelihood of faults over time.

MOT Failure Trends in Electric Vehicles

Electric cars, while still relatively new, are beginning to show trends in MOT results. Since EVs have no exhaust system or emissions, they avoid one of the major failure categories for petrol cars. However, MOT failures in EVs often relate to tyres, brakes, and lights. Tyres, in particular, wear faster due to the heavier weight and instant torque of electric vehicles.

Comparing Maintenance Costs

When it comes to maintenance, EVs generally require fewer routine services. Without oil changes, timing belts, or exhaust systems, electric vehicles tend to cost less to maintain annually. However, battery checks and software updates add unique expenses. In contrast, petrol cars require more frequent servicing, but repairs can sometimes be cheaper due to the wider availability of parts and mechanics.

Long-Term Considerations

While EV owners often save on running and maintenance costs, replacement batteries can be very expensive if needed outside of warranty. Petrol cars, although more costly to maintain annually, may not face such large one-off costs. Drivers must weigh short-term savings against potential long-term risks.

Planning Your MOTs

Whether you drive petrol or electric, MOTs remain a legal requirement for vehicles over three years old. Using tools such as Check MOT can help you stay on top of due dates and ensure your car is roadworthy. Regular maintenance and early checks can also prevent small issues from turning into MOT failures.

Conclusion

The debate of electric vs petrol vehicles extends far beyond fuel choice. EVs show fewer failures in some areas but introduce new challenges, while petrol cars remain more predictable but often costlier to maintain. As the UK transitions towards greener transport, drivers should carefully consider both MOT failure trends and maintenance costs before deciding which type of vehicle best suits their needs.

FAQs

1. Do electric vehicles need an MOT?

Yes. Like petrol cars, EVs require an annual MOT after three years.

2. Are electric cars cheaper to maintain than petrol cars?

Generally yes, due to fewer moving parts, though battery issues can be costly.

3. What causes MOT failures in electric cars?

Common issues include tyre wear, brake faults, and lighting problems.

4. Are petrol cars more likely to fail emissions tests?

Yes. Exhaust emissions are a common failure point for petrol vehicles, something EVs do not face.
