When comparing diesel SUVs to petrol SUVs in terms of reliability, several factors come into play:
Reliability Studies
- Fault Rates: Petrol cars generally have a lower fault rate compared to diesel cars. A reliability survey noted that 20% of petrol cars reported issues, while diesel cars had a fault rate of 31%. Most studies indicate that petrol engines are more reliable than diesel ones, though diesel engines are often perceived as longer-lasting due to their usage in high-mileage scenarios.
- Maintenance and Repairs: Diesel engines can be more expensive to repair if they break down. Not only did more diesel owners report paying over £1500 for repairs, but manufacturers also covered fewer repair costs for diesel vehicles compared to hybrids or petrol models.
Engine Longevity
- Diesel Engines: They are often more rugged due to higher compression ratios, which can contribute to better longevity. This makes them suitable for high-mileage use and tasks like towing.
- Petrol Engines: While not as robust as diesel engines in terms of withstanding high compression, they are generally more reliable in terms of fewer reported faults.
Usage and Suitability
- Diesel SUVs are ideal for drivers who cover long distances or need a vehicle for towing, as they provide better torque and fuel efficiency in these conditions.
- Petrol SUVs are more suitable for city driving or lower mileage users, offering a balance between performance and lower running costs in those scenarios.
In summary, while diesel SUVs may be perceived as longer-lasting due to their ability to handle high mileage and rugged conditions, petrol SUVs are generally more reliable in terms of fault rates. The choice between diesel and petrol SUVs should depend on the intended use of the vehicle.
