Is the Audi A6 Expensive to Run?

The A6’s ownership bills sit squarely in the premium bracket, yet remain justifiably competitive among comparable executive saloons. Fuel economy varies significantly depending on the engine choice. The efficient 2.0-litre TFSI delivers around 40-45 mpg in real-world driving, while the plug-in hybrid e-tron can achieve over 100 mpg when regularly charged. The powerful V6 models return around 35-40 mpg, which is respectable given their performance capabilities.

The initial purchase price reflects the A6’s premium positioning, starting from around £45,000 for entry-level models. Insurance costs will be higher than mainstream cars due to the sophisticated technology and higher repair costs. However, Audi’s reputation for build quality means reliability is generally good, especially with proper maintenance. Car finance options can help spread the cost, making this premium saloon more accessible. While it won’t be the cheapest executive car to run, the A6’s combination of luxury, technology, and residual values helps justify the investment.

Audi A6 Practicality & Boot Space

The Audi A6 strikes an excellent balance between luxury and everyday usability. The 530-litre boot is generous for the class, easily accommodating a week’s shopping or several large suitcases. The rear seats fold in a 40:20:40 split configuration, allowing you to carry longer items while still seating passengers. Inside the cabin, there are plenty of storage compartments for phones, drinks, and personal items, including a wireless charging pad for compatible smartphones.

Space for passengers is impressive throughout. The rear seats offer genuine comfort for adults on longer journeys, with ample legroom and headroom. For families or business users, the A6 provides the perfect combination of executive presence and practical versatility. Compared to other used Audi cars, the A6 offers more space than the A4 while being easier to manage than the flagship A8. Its refined ride quality and spacious interior make it an ideal choice for those who regularly carry passengers or need to cover long distances in comfort.

Absolutely love my A6. The interior quality is outstanding and it’s so comfortable on long motorway journeys. The technology takes a bit of getting used to, but once you do it’s brilliant. Only wish the boot opening was a bit wider.

Frequently Asked Questions

Yes, the modern A6 has proven to be reliable for daily use with proper maintenance. Audi has significantly improved build quality and reliability in recent years. Most mechanical components are robust and long-lasting. The main areas to watch are the complex electronic systems, which can occasionally develop minor faults. Regular servicing at approved centres helps prevent most issues and maintains warranty coverage.

When viewing a used A6, check all electronic systems thoroughly, including the MMI infotainment, air conditioning, and driver assistance features. Verify that the service history is complete, especially for diesel models which need regular DPF regeneration. Look for any signs of wear on the interior materials, as replacement parts can be expensive. Check that all recalls have been completed and that any software updates are current.

The A6 generally offers superior ride comfort thanks to its adaptive suspension system and excellent noise insulation. The interior materials and build quality typically feel more luxurious than the BMW. However, the 5 Series offers more engaging handling and a sportier driving experience. For pure comfort and refinement, especially on longer journeys, most drivers find the A6 has a slight edge over its Bavarian rival.

The A6 e-tron hybrid makes financial sense if you can charge regularly and do mostly shorter journeys. With a 40-mile electric range, many daily commutes can be completed on electric power alone. The fuel savings can be substantial, and company car tax benefits are significant. However, if you mainly do long-distance driving without regular charging opportunities, the conventional petrol engines may be more practical and cost-effective.

For most buyers, the 2.0-litre TFSI petrol offers the best balance of performance and economy. It provides adequate power for most situations while returning respectable fuel consumption. The plug-in hybrid is ideal for those with regular charging access and shorter commutes. The V6 engines are superb if you prioritise performance, but running costs will be higher. Diesel versions are best for high-mileage users, though they require more careful maintenance.
