The start point for the best source of fleet information
What's new: The RS6 is the most powerful estate car in the world. Its 580PS 5.0-litre V10 engine roars to 62mph in just 4.6secs.
Excellent: The engine. The sheer brute force powering this car means it is as quick as Audi's flagship supercar, the R8. It accelerates rapidly at any speed and sounds magnificent.
Good: Despite all this power, the RS6's looks are remarkably understated. There are only a few tasteful tweaks to the standard A6, meaning you avoid unwanted public attention.
Average: .but 20.2mpg on the combined cycle ensures you'll be well known at your local petrol station. The 80-litre tank means filling up with premium will be a pricey experience.
Poor: Running costs are astronomical. Also, pop the suspension into 'Sport' mode and your back'll never be the same again.
Verdict: Try as you might, it's hard to justify owning the world's most powerful estate car at any time, especially in a troubled financial climate.
