Audi RS4 Avant review – MPG and running cost
MPG is rated in the high-20s range, which is totally doable, and relatively reasonable considering the punch
An advantage of the RS4’s relatively small body, engine and low (relative) power figure is that its quoted 30-ish MPG is entirely achievable on a daily mix of driving, even with a few heavy throttle applications thrown in.
The RS4’s footprint is rather chunky with 275-section tyres all-round, it’s got some aggressive geometry, and a pretty even spread of power delivery that will make tyre bills more substantial than with a normal A4. That said, BMW M3 and Alfa Giulia Quadrifoglio owners will be delighted with the savings.\
From all accounts, the RS4's Porsche-developed V6 engine is a resiliant and somewhat understressed unit, meaning that general reliability is pretty good. The engine's now utilised across the whole Porsche passenger car range, in many cases paired to a hybrid drive module.
