About the 2021 Audi R8

The 2021 Audi R8 is a premium performance car. Our records list a 5204cc petrol engine, though engines vary between versions. 297 MOT tests were recorded on this model in 2024, making it a less common model in the UK market. Among all models from 2021, the average MOT pass rate is 92%, and this model beats that benchmark.

With an average of 10,061 miles recorded at its 2024 MOT tests, Audi R8 owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

2021 Audi R8 Fuel Costs

The 5204cc petrol engine is on the larger side, so fuel won't be this car's strong point. Expect around 30 mpg in mixed driving, which works out to roughly £1,958 per year with petrol at 174.57p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year).

What does it cost to own a 2021 Audi R8?

Total estimated annual running cost is £2,413 (£201/month), broken down as £1,958 fuel, £200 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 94% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

Audi R8 Reliability Trend

Newer Audi R8s pass their MOT more often than older ones, by 3 percentage points on average, which is mostly down to age and wear.

Buying a Used 2021 Audi R8

At 5 years old, the Audi R8 offers good value with plenty of life remaining. Most manufacturer warranties will have expired, so a pre-purchase inspection is worth the cost. If you're flexible on year, the 2013 model has the highest pass rate at 98%.

Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

Oil Consumption

Low risk

Larger petrol engines can develop higher oil consumption as they age. Check the oil level and look for blue smoke from the exhaust.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
