Got a sourse of this info?
I just dont see how 550 is matching S6's performance, when it won comparo between M5 and AMG
When i was shopping for sport lux mid-size sedan few month ago, i was pretty much between 550xi and S6
S6 was a lot better choice for me.
With new Tu engine, i dont see substantial changes in performance, plus at extra 300lb, it'll be tough for 550xi to match S6 in acceleration/handling dept.
