2001 Audi A4 2.0 TDI quattro

Update 10/18/19: This neat A4 sold for an impressive $16,100.

If you read the title and look at the photo above, something doesn’t seem quite right. Obviously, I’ve made a mistake and this is a S4, right? It looks like an S4. There was no diesel B5 brought to the U.S.. And, the coup de grâce of my mistake was surely that even in Europe there was no 2.0 TDI Audi B5. Well, just like most other small chassis Audi platforms, the B5 has proven remarkably adept at accepting other engines – and this one’s a doozy.

The builder took a BHW 2.0 Pumpe Duse TDI borrowed from a Passat B5.5. In stock form, the BHW wasn’t the most impressive TDI from VAG. Producing 134 horsepower and only linked to an automatic transmission in the U.S., the Passat TDI was rated at only 38 mpg on the highway. I achieved that on a 100 mile trip the other day in my 1.8T, for reference. But, of course, the big news with the TDIs was torque and the BHW had 247 stock at 1,900 rpm. The builder of this car took the BHW bottom end, mated it to a BRM head from a Mk.4, and then slapped on a giant turbo. The result? 250 horsepower – the same as the S4 – with 400 lb.ft of torque claimed in a car that will return 45 mpg. And then they slapped it into a very discrete package; an original (and rare) Brilliant Yellow A4 replete with S4 body kit and interior. The result? Pretty impressive, if you ask me:

Halo Homologation-off: 1980 BMW M1 v. 1986 Audi Sport Quattro

It’s a bit amazing to consider that two of the most significant halo cars in German motoring history – both homologation models intended to lead their respective marques into the next decade – so closely paralleled each other, yet were so very different. It’s but a 35 minute train ride between Munich and Ingolstadt, and in the late 1970s both BMW and Audi wanted a range-topping model to grab attention. But their approaches were radically different. BMW designed a bespoke mid-engine, tube-frame supercar around a basic engine design it already had. Audi, on the other had, took a basic car design it already had and added a revolutionary drivetrain.

Both were styled by Giugiaro. Both had to be built out-of-house; Baur had a hand in each. Both had legendary engineers – Walter Treser and Roland Gumpert for Audi, Jochen Neerpasch at BMW. Both raced, though the series they were intended for were ultimately cancelled. Both launched a brand name – BMW’s M division, and Audi’s quattro (and later quattro GmbH). And today, both are both legends and highly sought by collectors. So today we have an interesting showdown; two prime examples have come to market and are nearly the exact same price. Of course, for that to occur the Audi entrant is the ‘ultimate’ evolution of the Quattro, the Sport model. So let’s put aside the ridiculous $700,000 plus asking prices of each of these cars for a moment, and consider – all things being equal (which they nearly are!), which one would you choose? Let’s start with the M1:

“The One” – 1993 Audi S4

Back almost exactly three years ago in 2016 I took a look at one of the best ’93 Audi S4s out there for sale. Today, it’s back again for trade – and has hardly changed. The seller has only accrued a hard to fathom 600 miles in that time on this pristine C4, while maintaining the near-perfect presentation. It was no surprise that two of our readers, including the ex-owner, spotted it up for sale and wanted to share it! The following is the original ad copy from October 22, 2016 – still relevant today, and perhaps moreso three years later:

Any time one of our readers sends in a car, I try hard to take notice. It’s not always easy, as we get a lot of emails and as this is really a spare time endeavor, it can be exceedingly hard to stay on top of replying to everyone. However, there was not just one reader who sent this car in. There were three. Almost as if they colluded, my inbox pinged earlier this week with the subject line “S4”. Though they’re getting harder to come across, it’s still relatively simple to find a C4 Audi today. Amazing as it may seem, a lovely black ’95 S6 merged into morning traffic right next to me just yesterday. They’re out there, and while they’re rare, they aren’t unseen completely thanks to religiously devoted followers, stout build quality, and unprecedented longevity. But the reason that three readers sent this car in was that it wasn’t just any C4 Audi – this might be the best one for sale in recent memory:

1985 Audi Sport Quattro

By 1984 the writing was on the wall, and the wild formula called Group B was mutating cars as if they had been supplied nuclear-tainted drinking water. Lancia went from the nutty but awesome and pretty 037 to the much nuttier, much less pretty but significantly faster Delta S4; a mid-engined turbocharged and supercharged all-wheel drive wonder. That matched Peugeot’s effort with the 205 Turbo 16, a mid-engined turbocharged and super-balanced all-wheel drive hatch. The competition was lighter and much better balanced than the Audi was, and all-wheel drive was no longer the trump card. The Audis had been fast but also a bit prone to understeer – something that won’t surprise anyone who has driven a 1980s Audi. Additionally, they were heavy compared to the competition even when fitted with special aluminum blocks instead of the road-going cast iron. One last complaint that the drivers had was that the windshield rake meant there was a tendency to have a large amount of glare that distracted the driver and navigators. Plus, Audi was at the limit of what it could develop reliably with the 10 valve turbo motor.

The response was the Sport. To drop weight, Audi chopped the best part of 13 inches out of the middle of the Quattro, making it a two-seater unless your passengers had no legs. They took the doors from the short-lived 4000/80 5+5 2-door and the windshield from the 4000/80, too – it was much more upright than the normal Coupe. The flares grew as well, another few inches in girth allowing now 9″ wide wheels with larger 235-45-15 tires. The body was made from carbon fiber and kevlar to help cut weight and was produced by noted special vehicle producer Baur in Stuttgart. And under the vented hood lay what would become the party piece; the 2.1 turbo motor now sporting 20 valves. The result was staggering in terms of road performance; in 1984, the Sport was the fastest accelerating road car you could buy to 60 m.p.h. at 4.5 seconds. Remarkably, 30 years on that would still be considered seriously fast. But it was the belching flames, the wail of the five cylinder and the wild slides that captured the imagination of the world. In rally trim, Audi saw a reported 600 horsepower from the monstrous S1 E2 depending on spec. On the road the Sport only saw half that output, but it also received a special interior to match the special exterior – heavily bolstered Recaro seats in special trim and a significantly revised dashboard with more gauges and a new readout. 214 of these special Quattros made it to the road at a somewhat staggering equivalent of $72,000 in 1984 – nearly double what the already expensive long-wheel base Quattro cost. As with all of the special homologation cars from Group B, the Sport was a truly special car then and is perhaps even more revered now:

1990 Audi V8 quattro

If Alfa Romeo built a German car, it would be the V8 quattro.

First, it was hugely complicated. There were computers controlling everything, and in the great manner in which Audi and Volkswagen developed their late 1980s computer technology, it worked great until it didn’t, at which point the car would be thoroughly incapacitated. One day driving my ’93 4.2, during a rain storm the “convenience controller” failed, opening all of the windows AND the sunroof and not allowing me to close them. Needless to say, it was less than convenient. Second, it hemorrhaged fluids. We’re not talking a little bit, either – full on “Oh, I’m sorry, did you want me to keep that $20 a liter worth of hydraulic fluid IN me?” hemorrhaging. Oil, coolant, transmission fluid…you name it, if you could put it in, it would instantly come out. It tried to kill me, too. Not just once, either. See, that fluid loss resulted in a buildup of oil gunk. Where does the oil gunk build up, you ask? On the throttle. This normally isn’t a problem, unless once in a while you opened the throttle. Then, it became a problem, as the throttle wouldn’t close. Again, not a problem so much on a 4000 quattro with all 115 stampeding horses, but in the ’93 V8 quattro, there were 2.5 times that amount – 276 horsepower with even more torque launching my 3,900 pound missile down Route 195. Leaks presented themselves in other odd ways, too – like, for example, when I got a self-imposed flat tire at a winter driving school. Out came the tools to jack the car up, no problem. However, when I went to retrieve the spare, a sad sight awaited me – the trunk had leaked into the spare tire well apparently, resulting in the space saver spare being thoroughly embedded in 10 inches of tire well-shaped ice cube. In story generation alone, the V8 quattro was by far the Professor Emeritus of my car history. Thirdly, no one knew what it was when you went to get a part. Allow me to present a theoretical trip to the parts counter – even at an Audi dealer…

Parts Guy: Hi, what kind of car?
Me: Audi
PG: What model?
Me: V8
PG: No, not what engine, what model.
Me: V8
PG: They made a model named V8?
Me: Yes
PG: (turns to other Parts Guy) You ever hear of an Audi V8?
OPG: He probably means A8.
Me: No, the A8 is the model that replaced the V8.
(both look confused)
PG: Okay, what year?
Me: 1993
PG: Audi made cars in 1993?
Me: Yes. Not many.
PG: Okay, the computer tells me that your car doesn’t exist.
Me: It’s outside. Would you like to see it?
PG: No, maybe I can cross reference the part. What do you need?
Me: The transmission control unit.
PG: ………………
PG: ……….. (turns to other PG and looks confused)
Other PG: Ah, you should probably just go to the dealer.

Fourth, when eventually you convinced someone who supplied parts for your non-existent car that it really was real, inevitably the part would be expensive. Really, really expensive. And, on backorder, or no longer available. It made repairs lengthy and always have at least one comma in the price estimate. That estimate was almost always below what it actually cost to get it running again, and when it did run again, inevitably there would be something still wrong that would need to be fixed on the next trip to the mechanic. And that was 15 years ago!

Yet, more than any car I’ve previously owned, it’s the one I’d want back.

1984 Audi 4000S quattro

Update 8/22/19 – this 4000S quattro sold for $3,000.

The 1984 Audi 4000S quattro is a bit of a unique beast. Though it appeared for all intents and purposes identical to the 4000S Limited Edition from the same year, underneath the two shared little in common. Indeed, when you lifted the covers much more of the quattro model was shared with its bigger brother, the exotic Quattro – the so called “Ur-Quattro” by fans. Herein lies part of where things get confusing in Audi history, since the actual development mules for the boxflared rally wonder utilized the 4000 (nee 80). You could make a pretty convincing argument that the small sedan was the original, but that’s neither here or there at this point and is generally semantics (though, it’s occasionally nice to splash the waters of reality on enthusiast’s ill-informed fires of unshakable belief). Whoever was technically first, there’s no denying that the 4000/80 model brought the idea of permanent all-wheel drive to a much more affordable market of rally-bred enthusiasts who eagerly snapped up the roughly 4,500 examples of the first year model. Radical looking changes came for the 1985 model year with a thorough refresh, and there are those who love both generations with equal aplomb. Admittedly, I’m a fan of the post-’85 models, sometimes referred to the as the “sloped grill” cars. But you don’t have to go far to find fans of the more square ’84 model. One reader of ours tasked me with the goal a few years back of keeping an eye out for a clean ’84. Easy, right? Not so fast…

1994 Audi 90CS quattro Sport

Audi’s nomenclature took an interesting turn once again in the early 1990s. From the B2’s “4000CS quattro” – the only way the car was available at the end of the run, Audi had introduced the tiered 80/90 quattro for the B2 model range. That culminated in the 90 quattro 20V, but even though the run of the B3 was short in the U.S., by 1991 the model was already 6 years old for the European market. Audi then skipped the 1992 model year for the 90, offering only the holdover 80/80 quattro while it readied the 90’s replacement. That replacement was…the 90. But strangely back again was the S/CS model designation in this “new” chassis, the B4, which was a heavily revised B3 chassis with some new sheetmetal and trim.

But the big news was new engines; gone was the NG and 7A, last of a long line of inline-5s that had populated the noses of small Audis since the late 1970s. In its place was the AAH 2.8 liter 12 valve V6. Rated at 172 horsepower and 184 lb.ft of torque, on paper it was the superior motor to the double-overhead cam inline-5 it theoretically replaced. But the power delivery and experience were entirely different. While the peaky 7A encouraged you to explore the upper realm of the rev counter, the AAH wasn’t particularly rewarding at the redline. Where it was superior was in low-end torque and it’s smooth power delivery, and though the cast-iron V6 was no lighter than the inline-5, it’s shorter overall length meant that some (okay, only a bit) of the nose-heaviness that had plagued the B2 and B3 series was forgotten.

But the ‘CS’ quattro moniker only lived a short two years in the U.S. before it, too, was replaced by the last-year oddly-named Audi Sport 90 quattro. ’94s are equally strange, being termed the ’90CS quattro Sport’. These were also some of the slowest-selling Audis in a history of not particularly prolific sales; Audi shifted only 718 1993 models and barely more in 1994 at 773. You’re much more likely to find a last-year model, as the Sport 90 quattro and the slightly lower-spec 90 quattro accounted for nearly as many sales as the ’93 and ’94 years combined. As with the prior B3 90 quattro, the Achilles heel of the B4 was the price. The base price for the 90CS quattro in 1993 was nearly $33,000, and add your taxes and a few options and you were close to a base M3 in ’95.

2003 Audi RS6 Avant

The C5 Audi RS6 was the first full-fledged RS model to head legally to North America. It was the stuff of instant legend, too, with a 450 horsepower twin-turbocharged V8 and enough tech to get you to and from the moon. And despite its relatively limited run, it’s been no stranger to these pages – thanks in no small part to the plethora of used examples on the market at any time. Indeed, just a month ago I counted no less than 10 for sale when I wrote up the unique 6-speed converted sedan:

2003 Audi RS6 6-speed

That car’s asking price has been reduced to a much more enticing $20,000 today. Yet for some, including this author, the fact that there was an Avant form of the RS6 that was left out of our market has always been a sticking point. Well, a few enterprising individuals have eliminated that need:

1984 Audi Quattro

We don’t often get to look at 1984 Quattros, and that’s for a good reason. While Quattros are rare stateside full-stop with only 664 brought here originally, just 10% – 65 – were ’84 model year cars. Like ’85, ’84 was a transition year as the newer dashboard, 8″ Ronals and a few other minor changes crept into production. LY5Y Amazon Blue Metallic was offered alongside the Helios Blue Metallic in 1983, but for 1984 it became the sole dark blue offered. It’s a very pretty color, and is here coupled were with some nice and common upgrades to the early cars. Most obvious are the addition of European H1/H4 sloped headlights and grill, which give the Quattro a more updated and aerodynamic look. More subtle is the tucking of the impact bumpers which combined with the headlights give a more Euro feel to this example:

1987 Audi 4000CS quattro

The Audi 4000 quattro was like a Sherpa to thousands of European car enthusiasts; a steadfast winter standby with slick styling and Rally-bred sure-footedness. On paper, looking back today the 4000 was probably a bit dull; nearly 2,900 lbs of brick-on-brick design with a measly 115 horsepower motivation from the slow-revving oddball inline-5 hanging entirely in front of the forward axleline. But numbers don’t tell the whole story of the B2 Audi, because in any configuration it’s a great handling car. The quattro, however, had some special features that would have been headline items for any sports sedan until very recently; four wheel independent suspension with a large front sway bar and four wheel disc brakes. Couple that with the first all-wheel drive system fitted to a small car, sprinkle some luxury items in and cut the price of the exotic Quattro in half, and it didn’t matter that it wasn’t particularly fast.

What the 4000 quattro was, though, was one solid all-around performer. The subtle changes from the front-drive sedan resulted in a car that felt more grown-up and refined, yet still pushed you to do silly Hoonigan things. 4000 quattro owners that I’ve talked to almost always have the same proud story; the time that they managed to get their 4000 quattro stuck. Normally, that would be a cause for embarrassment, but such was the grip of the plow-through-anything small sedan that it became a badge of honor when you outdid the car’s twin-locking differentials. The secret, of course, was just to make sure all four wheels were in the air! But because of this type of silliness-inducing competence coupled with dropping residual value and a second or third tier of ownership that didn’t always repair or maintain the cars, few are left in good condition. But once in a while one pops up that has you seeing red…LY3D Tornado Red, in this case:
