From the C3 chassis we looked at the other day to the launch of the C5 was just a scant 7 years. The styling was evolutionary and instantly recognizable, but the C5 really broadened Audi’s offerings in the U.S. market. Building on the success of the A4, Audi launched not only the normal sedan and wagon offerings, but the return of the S6 and introduction of new 2.7T performance models, along with the Volvo-challenging Allroad.
The pinnacle of the C5 was, of course, the twin-turbocharged all-wheel drive version you see here built by Audi’s skunkworks, quattro GmbH. With assistance from VAG-owned Cosworth Engineering, the resulting BCY motor cranked out a peak 444 horsepower at 5,700 rpms and an impressive 415 lb.ft of torque between 1,950 rpms and 5,600 revs. The body, brakes, wheels and suspension were all upgraded by quattro GmbH too, with plenty of technology incorporated to transfer the power to the ground and keep the RS6 planted. Though it was saddled with an automatic transmission only and tipped the scales at a massive 4,050 lbs, the tenacious all-wheel drive, computer programming and massive power resulted in a 4.4 second 0-60 sprint, besting both the contemporary M5 and E55 AMG. The RS6 had 14.4″ front brakes, dynamic ride control, and meaty 255-section Pirelli P-Zeros to control that speed. Lowered ride height, flared sills and fenders and giant gaping intakes and exhaust along with signature honeycomb grills set the stage for how these cars have looked since.
The first RS model imported to the U.S., Audi expected to sell 860 at nearly $80,000 a pop. But they didn’t. They sold more, such was the demand, with an estimated 1,200 making the journey to North America. But as with basically all complicated, fast older German cars, they’re not worth what they were new, making them very tempting in the used marketplace. And there are a lot of used RS6s out there to choose from at any given time – currently, there are 10 available just on eBay. The thing is, you should avoid most of them. But not this one:
Although the lower-output, less frills A6 4.2 is the sedan model I prefer (for some strange reason) from the C5 lineup, I was left disenchanted by the last one we looked at. Suggesting that by the time you corrected only the known faults your bank account would be empty, I headed out into the RS6 territory to prove myself right and that you could get a better car for the same money. And what to my wondering eyes did appear in the sea of gray, but a shining white RS6.
Now, on the surface, Polar White doesn’t seem either like the most exciting color nor the most rare thing out there. However, Audi claims that out of the 1,436 RS6s it sold here in 2003, only 5 were ordered in this color. That makes this particular RS6 quite special, as if the RS6 wasn’t special enough to begin with. But if you need a reminder about what’s what in the RS6, I went into further detail back in October:
2003 Audi RS6
If the color wasn’t special enough, this particular RS6
is was also being offered in a no reserve auction and the price is so far on target to prove my supposition regarding the A6 4.2 right:
Update 11/25/18: This S4 sold for $8,302.
Continuing in my theme of the ultimate Audi garage, this post is going to seem a little strange. That’s because if I was going to pick an Audi sedan to collect, the second generation S4 would be pretty low on the priority list. In fact, I’m not sure it would make the top five. Without a doubt the D2 S8, the B7 RS4, the C4 S4/6, the D11 V8 quattro 5-speed, and the 4000CS quattro would all make it higher on the list.
It’s not that the B5 S4 isn’t compelling, with the twin-turbocharged V6 cranking 250 horsepower through a 6-speed manual. Barring the RS4 listed above, a box-stock B5 S4 will outperform everything else on that list in virtually every test. It’s just that the B5 S4 is a lot more desirable when presented as an Avant. So why is this sedan here? A few reasons. First, it’s Nogaro Blue Pearl Effect, and that should get a pass every time. Beyond that, it’s pretty clean, it’s got the unusual but pretty light Silver leather interior, it’s all stock, and it’s a manual. But as an added bonus, it’s also no reserve:
In recent posts I covered both the importance of the B5 chassis and its development into nuclear-grade weaponry in the RS4. In the midst was the substantially more tame yet still quite exciting S4 Avant.
Audi brought the S4 Avant to the United States for the first time in 2001. It joined the sedan lineup and offered a follow-up to the large chassis S6 Avant from 1995. Instead of the traditional inline-5 motivation, though, Audi had developed a new 2.7 liter version of its V6. With a K03 turbocharger strapped to each side, the APB produced 250 horsepower at 5800 rpms and 258 lb.ft of torque at only 1850 revs. Like all the B5s, Audi’s new generation of ‘quattro’ used a T2 Torsen center differential and relied upon an electronic rear differential utilizing the ABS sensors. The B5 chassis used the same technology on the front differential as well and was capable of independently braking each front wheel to try to sort the car out through its dynamic stability program.
But the real fun was that it was available as an Avant and with a 6-speed manual. Just over 1,500 were claimed imported between 2001 and 2002’s model years, with about 600 of those being Tiptronic equipped. Light Silver Metallic was by far the most popular color ordered, and this particular Avant is one of 358 LSM manuals brought in for the 2001 model year:
Here we are a week after looking at the 1990 Alpina B10 BiTurbo, and by chance, we get to look at a second BiTurbo. Last week’s was seriously suspect; there were alarm bells throughout, as major chassis issues and incongruous details were capped by a seller clearly looking to deceive the market. At first glance, there’s some cause for concern here, too, as we’ll see in a moment. Is this the case of another crestfallen hero, or does this super sedan hold true to its heritage?
So the last few listings for Alpinas have been….well, quite disappointing to say the least. Most recently was the “B12 5.0”, a car which was cleverly listed to avoid the discussion about its actual provenance. It worked, as the ’88 750iL sold for $23,600:
Another Almost Alpina Alumnus: 1988 BMW 750iL “Alpina B12 5.0”
Before that I looked at two E30s, both of which had some questions about their history and authenticity, though they both looked the part:
Tuner Tuesday E30 Showdown: 1986 Alpina C2 2.5 v. 1987 Hartge H26
Then there was the other C2 2.5, which I was able to confirm after a long time was another assembly of parts rather than an original build:
Mystery Solved?: 1987 Alpina C2 2.5
Not a great record, eh? But all of these auctions went to show that it was very important when checking out these cars to make sure that they had a well-documented history confirming their authenticity. So the other day when a B10 BiTurbo – one of the most sought Alpina models out there – was narrowed into my search criteria, I knew it was worth a look. And at first glance, it all seemed to be right. Did a scrutinizing hold up that belief, or is this another case of ‘can’t judge a book’?
The C5 Audi Allroad, a car that can’t be talked about without someone bringing up the photo of MacGyver being thwarted by one.Â Now a punching bag by many in the automotive world, I personally don’t think it is worse than any other German car that is over 10 years old. Yes, a twin-turbo V6 and air suspension do make things a little more complicated, but if you stay on top of potential issues, I don’t see the a giant problem with owning one of these. Fortunately, the owner selling this 2001 outside of Cleveland gave this green machine all the love it needs â€” and maybe even a little more.
While the C6 RS6 Avant and B7 RS4 Avant have been nice to dream about, the reality is that both are pretty unlikely in the near future to be making the trip ‘across the pond’ anytime soon. So let’s consider something which both could, and might.
The B5 RS4 was a legend right when it launched, but for some reason it seems overlooked in the marketplace today. Not as exotic as the RS2, nor as fast as the newer crew of turbocharged Audis, the B5 generation somehow feels lost. It doesn’t help that it was insanely popular to mimic the model’s gaping grills and signature widened flares here, nor that the RS4 engine upgrades are fairly common among enthusiasts. But when you see a real RS4, it’s easy to see why this car was so highly regarded at the time.
First, it’s a very sharp looking car. Nogaro Blue was the defining color for fast Audis in this period, but boy does Imola Yellow stand out. The stance, wheels, flares and bumper covers along with more pronounced exhaust all pull together to make the RS4 feel much more special than a normal S4 Avant. And with 375 horsepower on tap from the Cosworth-developed version of the 2.7 liter twin-turbo V6, it’s not exactly like the B5 RS4 was pokey. In fact, the power-to-weight and performance is nearly identical to the later B7 RS4.
You want power? When Cosworth slapped a few turbos onto Audi’s venerable 4.2 liter V8 for the C5 RS6, that’s what you got. 450 stampeding horsepower and 428 lb ft. of torque meant that in the early 2000s it was the model to beat. But AMG and BMW M quickly caught up and surged past the C5’s power output – even when Audi upped it with the “Plus” model to 469 hp.
The launch of a new RS6 based upon the C6 platform allowed Audi some room to expand the model’s engine output by literally expanding the engine: now 10 cylinders displaced 5.0 liters. Straddled by two turbochargers again, the second generation RS6’s power output leapt into a new league, with an almost unfathomable 571 horsepower and 479 ft. of torque. The C6 is a heavy car, but it was capable of 911-scaring 0-60 runs and could top 170 mph with ease.
What’s amazing is that Audi’s replacement for this car, the C7, moved to the new twin-turbo V8 4.0T motor. More power right? Well, not so fast; it actually produces about 11 horsepower less than the peak performance of the V10, though I’ll grant that the additional gears and greater torque mean it’s a functionally quicker car (as if it needed to be). Well, quicker than a stock one, at least, because this particular RS6 Avant has been ‘slightly’ upgraded to north of 700 horsepower.
While BMW’s M5 has been the benchmark for performance sedans since its inception in 1985, there have been plenty of challengers along the way that have really pushed the limits of sedans to new levels. The Lotus Carlton, for example, completely changed what going fast with 4-doors meant in the early 1990s. With twin turbochargers slapped on an otherwise unassuming inline-6, the bespoilered and wide-wheeled Opel packed 377 horsepower and could hit 180 m.p.h. flat out in 1990.
That meant the next generation of super-sedans would have to up their game, and constant brinkmanship ensued; the 3.8 upgrade to the E34 M5 hit 335 horsepower. The 500E packed 322, and Audi’s C4 S6 Plus matched that amount. They were still short of the Lotus, though, and playing catch up. Moving into the late 90s, power levels started to go crazy.
The C5 S6 launched in 1999, now with 335 horsepower. The same year, Mercedes-Benz entered with the E55 AMG at 349 horsepower. But both paled in comparison to the new E39 M5 with 400 horsepower – the undisputed king of super-sedans at the time. That would change in 2002 when Audi’s quattro GmbH launched its newest creation. With help from Cosworth Technologies, the new RS6 sported two turbos on the 4.2 liter V8 seen in the S6. The result was an impressive 450 horsepower driven through all four wheels. Giant wheels filled massive flares, at the front huge gulping intakes fed the intercoolers, and special exhaust and gills popped up everywhere. It was the new super-hero sedan and the result was…well, fast. The limited nature and performance potential of these RS6s have meant they’ve retained greater value than the normal C5 range, though they’ve been in steady decline. Today, we get to test the market on a well used example – where do these C5s sit today?
