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 27 - 36 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.

The S4 is more economical than the model it replaces, but Audi still has no real answer to BMW’s excellent Efficient Dynamics technology, which improves fuel consumption and reduces emissions considerably. Nonetheless, drivers ought to achieve 25mpg in everyday driving conditions – reasonable considering its high-power performance capabilities. Sky high CO2 emissions mean top-bracket road tax costs and insurance will be pricey too.

The Audi S4 isn’t the car of choice for eco-friendly drivers. Yes, fuel consumption is better than before and emissions are lower, but it’s still in the highest tax band with good reason: it produces more than 350g/km CO2. Those attracted to the S4’s design but deterred by its green credentials could go for a much more economical diesel A4 model instead.

The previous generation A4 range was exceptionally well built and we’ve heard few complaints from owners. The solidly-assembled S4 should earn a similar reputation.
