Audi A5 running costs: what UK ownership really costs
Audi A5 UK running costs: fuel or electric, insurance group, road tax, servicing and depreciation.

The Audi A5 offers a balance of performance and luxury, but running costs can vary significantly based on the model and engine choice. Fuel efficiency, insurance group, tax band, servicing intervals, and depreciation all contribute to the total ownership costs, making it essential for potential buyers to consider these factors.
Fuel Costs
The fuel costs of an Audi A5 depend largely on the engine type and driving habits. Petrol engines typically offer lower fuel efficiency compared to diesel variants, with the latter providing better miles per gallon (MPG) figures. For example, the 2.0 TDI diesel can achieve around 55-60 MPG, while the 2.0 TFSI petrol averages about 40-45 MPG.
With petrol prices fluctuating, owners should expect to spend a significant amount on fuel, especially if they opt for the more powerful engines. Choosing a diesel model could provide savings on fuel in the long run, particularly for those who cover high mileage. Additionally, Audi’s plug-in hybrid versions offer an electric-only range, which can further reduce fuel costs for urban driving.
Insurance Group
Insurance costs for the Audi A5 can vary widely depending on the specific model and trim level. Generally, the A5 falls into insurance groups ranging from 30 to 50. Higher-performance models, such as the S5 and RS5, are likely to be in the upper insurance brackets due to their increased power and performance capabilities.
When selecting an Audi A5, it is crucial to consider the insurance group as it directly impacts annual premiums. Drivers with a clean driving record may find more competitive rates, while younger or less experienced drivers may face higher costs. Shopping around for insurance quotes can help mitigate these expenses.
Tax Band
The Audi A5’s road tax band is determined by its CO2 emissions, which vary between models. For example, the 2.0 TDI diesel models typically fall into lower tax bands, while the more powerful petrol engines can incur higher tax costs due to increased emissions.
As of the latest tax regulations, many A5 models are subject to annual road tax fees that can range from £0 for low-emission variants to over £500 for higher-emission models. It’s essential for buyers to check the specific emissions figures of the model they are considering to accurately estimate their annual tax liabilities.
Servicing Intervals
Audi recommends servicing the A5 every 9,000 to 19,000 miles, depending on the engine type and driving conditions. Regular maintenance is crucial for keeping the vehicle in optimal condition and can prevent costly repairs down the line.
Service packages are available, which can help manage costs over time. Audi’s fixed-price servicing plans can offer peace of mind, allowing owners to budget for maintenance.
Typical Depreciation
Depreciation is a significant factor to consider when purchasing an Audi A5. Luxury vehicles like the A5 tend to depreciate faster than mainstream brands, with estimates suggesting that they can lose around 50-60% of their value within the first three to five years.
Factors influencing depreciation include mileage, condition, and market demand. Models with desirable specifications and lower mileage tend to retain value better. Buyers should consider the potential resale value when selecting options and trim levels, as this can impact overall ownership costs.
Conclusion
Overall, the Audi A5 presents a compelling option for those seeking a blend of style, performance, and comfort. However, potential owners should be aware of the associated running costs, including fuel, insurance, tax, servicing, and depreciation. By understanding these factors, buyers can make informed decisions that align with their budget and driving needs.
