There Was A Time When Americans Could Buy A 300-Horsepower Supercharged Wagon From Audi: Holy Grails


For a short period of time, American car enthusiasts could have purchased a wagon in a rare configuration. Sold from just 2009 to 2011, Audi offered its stately A6 in an enticing configuration. The Audi A6 Avant 3.0T looked like your everyday Audi wagon, but under its hood sat a supercharged V6 pumping out 300 horsepower 310 lb-ft to all four wheels. Yet, so few people bought them that there are just 1,066 of them on the road.

Welcome back to Holy Grails, the Autopian series where we show off some of the coolest, most underrated cars that you love. Now that this series has run long enough, I’m beginning to see a trend in the vehicles being sent in. It seems that our readers really love vehicles from that time when Chrysler was experimenting with turbocharging. Ford and Chevrolet also get some love with interesting versions of their trucks and vans. And one vehicle sent in is so rare that I could not find a single piece of official documentation or even a story on it — even from a bad source! I’m excited to write that up; please keep those grails coming because calling them awesome is an understatement.

Last week, reader Jack Trade alerted us to a Ford Mustang that was sold for just a single year. On paper, the 1995 Ford Mustang GTS was just a cheaper version of the Mustang GT, offering V8 power and tossing everything that you didn’t need into the trash. But there was more than that going on, as this car was essentially the last breath of the third-generation Fox body experience. It was powered by the 5.0 HO V8 that was housed in the old Fox body but in a new package. That made it a callback to the famous Mustang LX, which featured a similar formula of all firepower and nothing else.

Today, we’re returning to a familiar formula for this series and giving you a powerful, rare car that didn’t sell many examples.

Audi A6 Avant 2009 1600 06

When reader PlayswellwithNOthers sent in this recommendation, I initially passed right by it thinking that it can’t be that special. I mean, Audi has a long history of selling wagons, so this couldn’t be that rare, right? Well, digging into this further, I discovered that PlayswellwithNOthers is onto something here.

Launched in 1994, the first-generation Audi A6 actually started off as a facelift of the Audi 100. As the UK automotive service company RAC notes the Audi 100 (Audi 5000 in America) was selling slowly and when it got a facelift, Audi renamed it the A6 to go along with the automaker’s new alphanumeric naming scheme. As Motor Trend notes, along with the C4 platform A6 mid-size sedan came a wagon. Around this time, Audi also renamed the S4 to the S6, and the S4 name would return later on.

Audi A6 C4 757 23

One way Audi kept the A6 exciting is with a variety of engine choices. Motor Trend notes that 2000 was a year with some sizable updates. By now, the A6 had evolved into its second generation, which rode on the C5 platform. Along came a 4.2-liter V8 making 296 HP that drove all four wheels. Also on deck was the 2.7-liter twin-turbo V6 that made 250 HP and once again, drives all four wheels through Audi’s Quattro system.

It was also in 2000 when Audi also introduced the Allroad as a version of the A6. This came with an adjustable air suspension, higher ground clearance, and a body with a bit of off-road chic thanks to its gray bumpers and fender flares.

Audi Allroad Quattro 2000 1600 04

While Allroads can be pretty decent when the going gets tough–the A6 used a Torsen-based all-wheel-drive system–they’re known for being quite fragile. Perhaps amusingly, while I’ve owned a Volkswagen Phaeton, have owned a Volkswagen Passat W8, and currently own a Volkswagen Touareg V10 TDI, I currently have no desire to own an Allroad, in part because of those horror stories.

When the C6 third-generation A6 arrived in 2004, Audi kept things pretty spicy. Perhaps the most famous version of the A6 back then was the S6. Introduced in 2006, the S6 went even further than just a 4.2-liter V8. Pop the hood of an S6 and you’ll find a 5.2-liter V10.

Facebook Marketplace

Contrary to what online sellers say, this is not exactly the same V10 out of the R8 or exactly the same V10 from a Lamborghini, but it was still pretty incredible. You got that lovely V10 exhaust note, 435 HP, and a 0 mph to 60 mph sprint in just 5.2 seconds. And you got all of that in a stately sedan package. And yet, even these are surprisingly cheap on the used marketplace; I can usually find at least one for under $10,000.

This performance monster perhaps overshadowed another potent version of the A6. Starting in the later part of 2009, you were now able to spec your A6 out with a 3.0-liter V6, and this unit was cool, as it featured an Eaton four-lobe supercharger, capable of 11.6 psi of boost. And if you like your roofs long, I have good news because you can get it in an Avant.

This is the one that PlayswellwithNOthers says is a real holy grail:

I nominate the 2009-2011 Audi C6 4f A6 Avant 3.0t as my Holy Grail. It is a great-looking (they still don’t look outdated to this day) wagon that came with the very easily tunable and surprisingly reliable 3.0T supercharged V6 (engine code CCAA, type EA837). The 2009 facelift of the Audi A6 was the first vehicle to feature this engine.

Rated at 300hp and 310lb.-ft. in the US market version, it makes the Audi A6 wagon a great sleeper. As far as technology is concerned, the A6 came with Audi’s MMI infotainment system and was available with features such as 3D maps, traffic guidance, blind spot warning, lane assist, adaptive cruise control, adaptive headlights with cornering lights, high beam assist, and other systems that are now common in most vehicles.

It is a nice big family cruiser, that is also very fun to drive, especially when tuned (up to ~480hp/~450lb.-ft.). Being a fairly rare vehicle, a following has developed and when a nice one comes up for sale, it usually does not last long. There is even a thread on the Audizine forum for 3.0t Avant for sale sightings.

For the 2009 model year, only 262 A6 Avants were imported to the US. 2010 and 2011 were slightly more, but the total number of supercharged A6 wagons is said to be below 2,000.

PlayswellwithNOthers somehow understated how rare these wagons are. According to a forum post on Audizine, which claims to have come from direct contact with Audi, there were a total of just 1,066 of these sold in America. That makes these rarer than even some of my favorite cars. It’s rarer than the concept car-turned-real car Smart Crossblade. It’s even rarer than the Volkswagen Phaeton!

Perhaps a reflection of its rarity, while I’ve found many reviews of the Audi A6 3.0T Quattro sedan, I’ve found few for the Avant. One is this AutoGuide review, which found that the supercharged V6 dished out performance similar to the V8:

Strangely, both the V8 and 3.0T do the 0-60 mph run in almost identical times, with the supercharged six posting 5.9 seconds and the V8 a 5.8 second run.

In reality, the new engine is significantly lighter than the old V8 – helping the middle model to weigh in some 200 lbs. less. Not only does that aid acceleration, but fuel mileage as well, with the 3.0T averaging 21 mpg to the V8’s 18. Audi rates the car at 18-mpg city and 26-mpg highway. Otherwise, both share the same six-speed automatic transmission with Tiptronic, and quattro all-wheel drive hardware.

This review ended by saying that the A6 3.0T falls short of the competition, saying that it crashes over bumps and that a BMW 535i xDrive would leave it in the dust. In a period Car and Driver review, the tester found it to be slower than both the BMW and a Mercedes E550 4MATIC. However, the Audi still had a trick up its sleeve. The V8 in the Mercedes and the twin-turbo six in the BMW were both more thirsty than the Audi. And in Car and Driver’s test, the 3.0T actually beat Audi’s own A6 4.2 V8. Basically, it seems that this Audi wasn’t the fastest or the best-handling competition on the block. However, it managed to give you V8 performance without the V8 fuel economy penalty.

Still, that wasn’t enough, apparently. The A6 Avant 3.0T, which started at $53,310 (the sedan was $52,425), wasn’t long for this world. C6 A6 production ended in 2011, and while the supercharged engine carried over to the new fourth-generation C7 A6, the Avant did not. In fact, the A6 would go without a wagon version in the United States until 2020, when it came back as the Allroad. And by that time, the Allroad had been dead for a while, too.

Perhaps as another example of this vehicle’s rarity, I found only a couple of them for sale. Here are two for sale in California. I found a bunch of listings all claiming to be wagons, but they were clearly not, which is a bit weird. It does seem that if you can find one, hold onto it because these wagons don’t seem to come by often.

  1. Every time you mention that V10 TDI Toureg of yours, my heart fills with envy and greed. I start devising plans to travel to Illinois, steal the car and smuggle it back into Canada.

  2. Yeah, big nope. If you ask most Audi enthusiasts, that is not a holy grail at all because it was only offered with a slushbox.

    Real OG Audi holy grail is the 95 UrS6 Avant. Only around 300 were ever imported, and this was the closest you could get to a legit RS2 until the past few years when they became legal for import. Same engine and transmission as the RS2, but with a smaller turbo/more restrictive manifold/different software (technically the intake was different as well but it doesn’t really have any impact on performance).

    I was lucky enough to track down a NOS RS2 Turbo, scored a deal on a Wagner EVO RS2 manifold (outflows the RS2 manifold by large margins), and updated my injectors/ECU. Did a short history lesson on the development of this car, and timelapse of the entire RS2 upgrade here:


    Thing is a BEAST in any weather condition.

    1. You know, I liked this supercharged wagon, but you sold me even harder on the 95 UrS6 Avant. Don’t be surprised if your counter shows up soon. 🙂 This week, a weird Citroen is taking the helm.

    2. You beat me to it. Urs6 is way rarer, has a way cooler engine, and was sold only with a stick in the US. Much more holy grail status since David insists on manual transmissions. Most urS cars have crazy miles on them because they were robust and overbuilt too, not the maintenance nightmares of later Audi’s. I rather have a C5 S6 avant over the C6 A6 in the article. If you are stuck with the automatic might as well have the sweet sounds of V8 and nicer sport seats. It was also a very rare car.

    3. Urs6 avant is amazing but so hard to find. Our local German indie shop owner rolls the 100/200 avants with fat turbo 20vs. So fun to watch them squat at launch.

      Personally I love all the holy grails as it is fun to learn about weird ones you’d forgotten about.

    4. Cool video! I was too scared to work on my 2006 A4 because you had to remove most of the front end to do anything to it. Thats the only Audi I’ve ever owned and was just a base 3.2L, but dang that thing was a joy to drive.

      1. Quick correction: the C4 generation Audi was sold as the 100/A6 and S4/S6 in the US. The C2 was only sold as the 5000, if I remember correctly, and the C3 was sold as the 5000 until the late 80s, and was then renamed, matching the RoW market, to 100 (n/a) and 200 (turbocharged).

        The 200 20v would make a much better holy grail than this.

    5. I drove one meh, the slushbox was a no deal for me, my nephew in Berlin has a manual one with closer to 400hp that he is selling- if I can get a deal on shipping it is coming to Canada

  3. The Buick Regal TourX wagon had a turbo-4 and probably a GM Performance tune option or something to make it 300 hp… right? … RIGHT?

    I know some versions of that turbo had dealer-installed performance upgrade options, and some of them may even work on the TourX…

  4. My Audi ‘holy grail’ is a manual A4 quattro convertible with the 2.0 TDI.
    So a diesel, manual, all wheel drive convertible.
    Sadly, I think it wasn’t available in the US in this configuration.

  5. Here’s another wagon Holy Grail: the Jaguar XF Sportbrake. Similar to the Audi performance wise (unless you got the S trim with 380hp), but with less than 250 sold in the States and arguably better looking.

  6. Can’t help but think this wasn’t a Holy Grail, just because there wasn’t anything it was superior at. A few more mpg isn’t that big of a deal.

    Probably makes me a heathen, but on paper if I had to pick up an AWD wagon with a slushbox from the ’00s, I’d prefer a Magnum RT. It might as well have a big, dumb powerplant to go with its dumb transmission.

    1. Nope. Audi 20v is extremely robust since it was battle tested in WRC competition. Audi’s “unreliable” reputation came after the C4 chassis, with the C5/B5. They were getting hammered by Japanese luxury brands and added tons of gadgets, while cutting costs, and cutting testing. Result was a reputation that still haunts them to this day. The only failure point on a the 20V I5 is the 3 plastic coolant fittings, one on the back of the head, a coolant T, and the thermostat housing. Once you replace those with aluminum ones the drivetrain will easily last 200k miles, many are seen for sale with 250-300k on them, no rebuilds.
