Unicorn Killer: 2005 Audi A4 2.7T Avant Ultrasport 6-speed

While it was certainly impressive to see the unique Aquamarine S4 Avant over the weekend, for nearly everyone it was a letdown. Many of the faults would be excusable were it not for the outrageous asking price – getting on for four times the market value of a decent “normal” S4 Avant. Of course, one of the great things traditionally about Audis is that the chassis flexibility means parts from a myriad of other models work across platforms. So, unhappy with the available options out there, why not build your own super Avant?

That’s exactly what folks at Black Canyon Performance did, taking an already desirable B6 A4 Avant Ultrasport 6-speed and turning the wick up substantially. The modifications range from installation of a B5-generation 2.7T V6 to a factory RS4 interior and a special Porsche color – 7A1 Gray Black borrowed from the 997 GT3 RS, but don’t end there. Welcome to the Unicorn Killer….or was it Killer Unicorn?

It is with a heavy heart that I post this car that I have spent countless hours and dollars building. I am purchasing a house, and unfortunately I am forced to sell. It started life as a 2005 Audi A4 Avant Ultrasport 1.8T 6mt. Shortly after aquisition, I transplanted the engine and transmission from my prior 2001.5 Audi S4 Avant which was totaled when a driver pulled in front of me. The intention of this car was to have a high horsepower B6 Avant that would be reliable and enjoyable to drive on long road trips or up the mountains for summer or winter activities. And that’s just what I used the car for until it was very recently painted. I have driven this car across the country 5 times since the engine was swapped, and up the mountains for countless ski and mountain biking trips. Driven daily as well, this car has proved as reliable as if this car came from the factory with this drivetrain. Originally painted black, the car was recently repainted Porsche Grey Black. The door jambs, roof and engine bay were left black, as I didn’t feel it was necessary to paint them given the black interior and dark exterior.

This car is in excellent mechanical and physical condition. The car needs nothing, though the front rotor rings could use replacing sooner than later. As owned by an Audi mechanic, the car and drivetrain have been meticulously maintained. The timing belt has been replaced within the last 5,000 miles, and during the engine transplant all oil related gaskets and seals were replaced prior to installing into the car. The drivetrain is extremely dry. All electronics work perfectly, down to the cruise control. There are no warning lights on the dash, and no faults in the engine or other modules. The instrument cluster does read 90,xxx miles however photos were taken of the old and new clusters when they were swapped, to record the mileage. The exterior is in excellent condition – though not perfect. There is a bit of curb rash on a couple of the wheels, and the paint on the roof is the original black paint which is in good condition but not perfect. The paint is of high quality in workmanship and material. The interior is excellent. The headliner had started sagging so I removed and had the fabric professionally replaced when the car was painted. For the painting project, I personally disassembled body parts for paint and then personally reinstalled. Door handles, door locks, side skirts, trim, grills, bumpers, roof rails, mirrors, lights were all removed for paint. The under-window trim on the doors is new, as well as the windshield trim and cowel. The windshield is also new, and is factory Saint Gobain glass, and the wipers are new genuine Audi. Please feel free to ask quesions – I am sure I am leaving out a couple items.

And you cannot joy ride or waste my time. 🙂

Thanks for looking!

This car seems very well built and presented. The fit and finish of everything looks near-factory and so much has been replaced it’s nearly impossible to spot even a fraction of the 150,000 miles on the chassis. The RS4 interior is great and menacing, in keeping with the sinister exterior. The Ultrasport package is probably the best looking of the B6s, so that’s a win there too. High-quality, big-dollar Bilstein PSS9 suspension and Alcon brakes help keep the substantial power increase in check. I personally would opt for different wheels, but the “Peelers” are in keeping with the Audi DNA transplants. Power isn’t listed, but it’s safe to say it should be the equal of the B6 S4 and nearly double what a standard USP came with.

I’ve previously been pretty critical of pricing on USPs, and I think rightly so. While they’re neat cars, they’re not as special as their asking prices often indicate. But here, the price seems very much justified for the amount of work and the presentation of this turn-key, completely unique package. What a cool wagon!

  1. Sui Generis for sure. As long as you plan on keeping it till it returns to the earth, its seems like a screaming possibility. I’m not sure how you would recover your investment given that the next buyer as seller wouldn’t be the builder…..and by then…………

    I’m just a bit too practical I guess

  2. Yep, unique (excellent choice in wordage Woodie Man!).

    My take as an e61 owner is: Drive it, care for it and pass along what’s left, for what this is – COOL. MT Avants aren’t coming back – I’d sure like to have the quattro experience. Appears a very well thought & sorted mechanics’s ride.

  3. Why isn’t this being advertised as a stage three 2.7t? What am I missing? This thing should be putting out 400+ hp. I like the peelers. I love the color. I’d have to see it in person to see if I could live with the black door jambs and roof. I’m not sure I’d say this has an RS4 interior. It’s just the front seats. And the main difference between the RS4 Recaros and the boring old S4 Recaros is that the RS4 Recaros are emblazoned with RS4! But the silver piping is a nice touch. The standard A4 rear seats would feel a bit out of place to me, but if you’ve never had an R/S4 you probably wouldn’t notice. Nice build.

  4. Mismatched jambs, engine compartment and roof seem like a big negative, should have just repainted it in the original color. Have to wonder why it needed a repaint to begin with. Other than that it looks clean but still enough miles that you’d start to worry. A lot of money.

  5. So this car is 2 shades of black? I get not doing the jambs, but why not do the roof?

    This is a sweet ride though, looks like a lot of care and ability went into this build. I bet it’s a rocket.
