Speed, handling, practicality... almost everything, really
Erm, fuel economy?
What is it?
So this is the RS6 Avant, and the recipe remains pretty much the same as before. A big-engined version of the A6 Avant, all-wheel drive, auto 'box. But the execution is different. Cleverer. A 4.0-litre V8 instead of a 5.0-litre V10. Better balance. More thoughtful deployment of resources. Now, the previous bi-turbo V10 was an excellent express train for mauling Das Autobahn, but tended towards the bloodless when attempting a corner (it required extreme conditions to really show you what it was capable of), and fuelling it was like tipping buckets of unleaded down a car-shaped storm drain. So this version attempts to deal with some of those issues.
