Last week I wrote up a 2007 A6 3.2 quattro Avant S-Line, the end of a dying breed of luxury wagons from German manufacturers. But before they fully dismissed the large wagon from U.S. shores, Audi went out with a bang when it refreshed the A6 in 2009. Minor updates to styling once again brought the A6 in line with the new design language from Audi, but the real change was under the skin. As they had with the previous models, in an attempt to save some weight from the large Audis the company utilized aluminum throughout; the 3.0Ts featured aluminum hood and fenders like the previous generation S6 had. Additionally, just like the 3.2 had been, the new 3.0T was an aluminum block; the decrease in displacement was more than made up for with a literal boost from the supercharger. With a full 20% power increase to 300 horsepower and 310 lb.ft of torque at a low 2,500 rpm, the new 3.0T was a much better performer than the 3.2 FSi V6 had been and was, briefly, a defacto S-Avant that was missing from the lineup. On top of that, the new supercharged layout meant power increases are much easier to attain; as Chris Harris demonstrated with his stunning S4 v. RS4 comparison. Audi also moved away from its “S-Line” designations towards the new strata of Premium, Premium Plus ($1,400), and Prestige ($3,200) levels which added levels of electronic wizardry and small detail difference. That was on top of the raised base price, now $60,200 in 2010. If you though the 3.2 was rare, the 3.0T is downright hard to find even though they’re nearly new.
