Its obviosly that weight matters. RS6 isnt much faster in acceleration despite the heavy power advantage.
If this were sedans, I'd take the CLS or the E but Audi has a strangle hold on the Wagon market. RS6 for sure.
This is pretty much the league where every contender is "fast enough" for me. None of them would become a frequent track toy of mine due to their weight, so seeing all they'd do is cruise me (rapidly) from A to B, my choice is merely subjective. Might as well just go with the Benz then.
Wanted the RS6 till I found out it weighs more than 4000lbs. Mercedes weighs as much and the M5 looks ugly. I wont go for any of those cars. I prefer the MTM supercharged RS4 instead.
