I’ve spent some time in the past dissecting the neat C5 A6 4.2 sedans and what made them special:
The C6 model debuted in 2005, and it was a little more subtle (aside from the grille) but still packed a punch. The front end was stretched out 3.3″ to make more legroom in the cabin, and the whole car was wider as well. The standard A6 came with a 252 horsepower 3.2-liter V6, but you could opt to move up a liter and two cylinders to the 4.2 model once again. Now with a healthy 330 horsepower from a de-tuned version of the S4’s motor and a six-speed automatic instead of the outgoing five, the A6 4.2 was pretty quick – 6.1 seconds to 60, but like a freight train, the real speed was on-the-fly acceleration.
As usual, there were a bunch of grays, silvers, and blues along with white, and black on the outside, but if you wanted to stand out there was one pretty splashy color – Canyon Red Pearl Effect:
