new a6 2.0 or 3.0

I just bought the 3.0 and had a 4 hr trip home where I got 30 mpg on the freeway. The power is awesome. This is a heavy car to just have a 2.0 engine in it. If you are worried about mpg you should be looking at a VW not an Audi. Get the 3.0 you will not regret it.

I own a 3.0T. Had a 2.0 as a loaner for a couple of days....a very large difference in power. If you live in the country and don't drive for fun, then 2.0 will probably fit your needs. If you do city driving then the power helps. If you like to drive, then the power is what you need.
