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.
