As you’d expect from a large, high performance premium German car, Audi RS6 Avant running costs aren’t going to be cheap. Audi claims it’s capable of returning 28.8mpg on the combined cycle, but in the real world we’d be surprised if it managed more than 20mpg.
Still, using the claimed figures, there’s a 42% improvement in fuel economy and a 31% reduction in CO2 emissions over the previous RS6 model.
Servicing isn’t going to be cheap either, although specifying the variable servicing package and driving your car carefully will cut down on your out-goings somewhat.
With just one engine available, Audi RS6 Avant emissions are pegged at 229g/km. That figure is down from 333g/km in the previous RS6 and means it now qualifies for road tax band L one band lower than before. The decrease in emissions comes thanks to clever tech such as cylinder-on-demand – which deactivates four of the eight cylinders in the engine under certain circumstances to save fuel.
You shouldn’t worry too much about Audi RS6 Avant reliability. The firm has a fantastic reputation for well-built and resilient cars which go on for many hundreds of thousands of miles. Many of the parts in the RS6 Avant are shared with other models in the range, which means they’re tried-and-tested.

* The estimated fuel cost figure is based on an annual mileage of 10,000 miles and is a guide to how much this model will cost in fuel each year. It's calculated using the model's average MPG (calculated from both town centre and motorway driving) and the average fuel price from around the country. Actual fuel costs will vary based on driving style and road conditions.

How much is it to insure?
Vehicle excise duty (VED) varies according to the CO2 emissions and the fuel type of the vehicle. For cars registered before 01 March 2001 it is based on engine size. For cars registered on or after 01 March 2001 the VED or road tax is based on the car's CO2 emissions.
