Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 29 - 29 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

As you might expect with a high-performance four-door coupe, Audi S7 running costs are pretty high. With a claimed average fuel economy of 27.4mpg, which is likely to drop well below this once you start putting your foot down, visits to the fuel garage are likely to be frequent. Then there’s the matter of insurance, which is likely to be high. Labour rates at Audi garages are usually quite pricey so expect high service and maintenance bills.

As with the running costs of the car, Audi S7 emissions are fairly high. At 225g/km, CO2 emissions are acceptable for this type of car but you still fall in to the top band for road tax. You have to face the fact that you will see a fairly sizeable amount of money disappear from your bank for the first year, while subsequent years are still rather high.

If you’re considering buying an Audi S7, however, road tax costs are unlikely to be at the top of your agenda.

The German manufacturer has consistently performed well when it comes to build quality and this is unlikely to change with Audi S7 reliability. Many of the parts on the car will have already been put to the test in the standard Audi A7 car. The only unproven aspect is the new engine, but based on the firm’s reputation this should cause you no problems.
