Wagon Week: Forbidden Fruit – C6 and C7 Audi S6 Avants

For a few short years, Audi indulged us. In 1995 only, we received the first S6 Avant on U.S. shores; though the C4 Avant would soldier on until 1998, the 220-odd horsepower turbocharged 5 cylinder hooked to a manual transmission would be gone for a few generations and not seen again in the large wagon. Though the next generation C5 platform would grow in size, Audi would answer with a new S6 Avant for these shores. Now with a seemingly impressive 340 horsepower in an all-aluminum V8, it unfortunately only came to the U.S. in automatic form. It was still a very fast car, but one that catered to a slightly different crowd than the original. It was also, for all intents and purposes, a bit of a sales flop; enthusiasts I think correctly found it difficult to pay the premium when you could get the spiritual successor to the “Ur-S6” in the 6-speed manual, twin turbocharged Allroad 2.7T. As a result, when the new C6 platform launched, although there were new forms of the S6 Avant available, they stopped coming here. Indeed, as soon as we hit 2010, Audi stopped bringing the large Avant all together; you can thank the popularity of the Q7 for that. So today we’ll look at two of the forbidden fruit; the last two generations of S6 Avant that didn’t come to the U.S.:

Read the review:

The jump again from V8 to V10 was, at least on paper, pretty amazing. The result was near effortless speed in the C6 S6; with now 435 horsepower on tap, the C6 was no longer available as a manual. Instead, your only choice was the slick ZF 6-speed automatic with paddle shift, and it was more than capable of putting you back in your seat, especially on the highway. Outside, the S6 did what the S6 has always done best; it barely looked any different from a normal A6, with only devoted fans being able to spot small trim differences from the run of the mill TDis on the school run. That made it an incredible sleeper, but there was a new crop of super wagons – including Audi’s own twin-turbocharged RS6 Avant – that again made the gap between the 3.0T A6 S-line and the 5.2 V10 S6 a little bit of a head scratcher. Still, by U.S. standards, this S6 Avant is a bit of a steal right now, with bidding at just north of $11,000 on the no reserve auction. In part that’s due to the very different used car market in the U.K., and since these V10 models have shown remarkable longevity (memorably, Coventry Motor Car recently sold a V10 S8 with north of 200,000 miles) it could offer some serious high performance practicality on a budget.

Admittedly, the increase in power from the 5.2 V10 to the 4.0T V8 did not follow the same formula as Audi’s last few jumps; that would have put the base S6 around 530 horsepower, and instead it has only is rated at 420 horsepower. However, the combination of twin turbos and the new dual-clutch 7-speed S-Tronic gearbox make for much more usable performance. How good is it? In a test against the two seeming benchmarks, the BMW M5 and E63 AMG, Car and Driver picked the S6 as the best of the three despite lower performance. And what are we talking about with lower performance? How does 0-60 in 3.7 seconds sound? Three point seven seconds. It you longer to read that sentence. Unrestricted, it will do a reported 190 m.p.h.. These are numbers that were true supercar figures only a generation ago, yet the S6 will return 26 m.p.g, will get you up a snowy hill in the winter, can carry all your friends, their bags AND their ski equipment. And, it’s easily as luxurious as the most expensive Bentleys were only a decade ago, yet it’s cost – below $60,000 in this case, runs about the same amount as a fully loaded 3-series sport wagon in the U.S..

The RS6 might grab all the headlines with staggering performance, but you know what? The S6 Avant still is a very incredible package, and one I wished came to the U.S..

    I have yet to see a listing for any V10 powered Audi that doesn’t brag about it having a Lamborghini engine. Thing is, it’s not true. Audi’s V10 is 100% Audi. Lamborghini’s early 5.0 V10 is 100% Lamborghini. The later 5.2 is based on Audi’s design, but it has many differences that make it a loose association.

    The auction description for the ’06 is great – the hilarity only comes through on a careful reading.
    “Looked after extensively since ownership” “effortless amounts of torque” “a staggering 0-60” “Serviced annually and maintained regardless.” It’s like the person who wrote it knows what they wanted to say but juuuuust got the words in the wrong places.
