What is miles per pound?
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 21 - 22 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’d expect from a high performance saloon, the S6 is not cheap to run. Apart from the obvious high fuel bills, there’s also insurance and road tax to take into account while Audi parts and servicing aren’t cheap either. You can also expect to have to change tyres sooner than a standard A6, plus they will cost considerably more.
With a fuel economy figure of just 21mpg and CO2 emissions of 319g/km, it’s no surprise that the S6 scores badly on the eco front. The saving grace is that drivers of these cars tends to do fewer miles than most.
Audi has an impressive reputation for reliability and the S6 will be no different. It may be a high performance car but it’s been extensively engineered and should prove hugely dependable.
