The Audi Quattro, often called the “Ur-Quattro” or “original Quattro” by enthusiasts today, is not just another old coupe. Built from 1980 to 1991 on the same Typ 85 body shell as the front-wheel-drive B2 Coupe covered on our Audi Coupe VIN decoder page, it was the car that introduced permanent all-wheel drive to a mainstream road car, then went on to dominate Group B rallying and lend its name, quattro, to every all-wheel-drive Audi built since. If you are researching the shared front-wheel-drive Coupe and Coupe GT instead, that page is the right stop. This page is dedicated entirely to the Quattro: its real US-market VIN structure, its all-wheel-drive engineering evolution, and the rally history that made it a legend.

Below: verified WMI and plant data pulled from real US-titled production VINs and cross-checked against NHTSA’s vPIC database, a position-by-position guide to the 17-character standard, the engineering story of how the quattro system itself changed across the car’s own eleven-year run, and where to find the VIN on the car.

About the Audi Quattro

Audi unveiled the Quattro at the Geneva Motor Show in March 1980 and started customer deliveries that same year. It stayed in production, largely unchanged in concept if not in detail, through model year 1991, a genuinely long run for a low-volume performance coupe. Audi built roughly 11,452 units worldwide over that span. Of those, only about 664 were sold new in the United States, across model years 1983 through 1986, plus another 99 in Canada, making a real, federalized US-market Quattro a legitimately rare find today. US cars carried a base price of roughly $35,000 at launch, rising toward $49,500 by the end of the run, at a time when a Porsche 911 cost less.

The car’s defining feature was its drivetrain: a permanently engaged all-wheel-drive system built around a hollow secondary shaft running through the gearbox, sending power to a front differential mounted ahead of the engine while a conventional propeller shaft carried drive to the rear. Before the Quattro, permanent four-wheel drive belonged to off-road vehicles and military trucks. Audi’s engineering team, led by Jorg Bensinger, proved it could work in a lightweight road car without the weight and complexity everyone assumed it required, and the industry has never fully walked that lesson back.

The drivetrain itself evolved meaningfully during the model’s own production run, not just between generations of other Audi products:

Era	Years	Center differential	Notes
Quattro I	1980-1987	Open center differential, manually locked via a dashboard switch	Driver had to engage the lock deliberately in low-traction conditions; rear differential also manually lockable
Quattro II	1988-1991	Torsen type 1 center differential, automatic torque-sensing	Split power 50/50 under normal grip, shifting up to roughly 80 percent to either axle automatically as wheels began to slip, removing the need for driver input

That switch to a Torsen center differential for the 1988 model year (chassis letter J) is a real, documented turning point in the car’s own history, not marketing language: it moved the quattro system from something the driver operated to something that worked on its own, and the Torsen layout Audi introduced here stayed in Audi all-wheel-drive vehicles for roughly two more decades.

Engines evolved on a similar timeline, all turbocharged inline five-cylinders:

Engine code	Displacement	Valvetrain	Years	Notes
WR	2,144cc (2.1L)	SOHC, 10-valve	1980-1987	Original engine, roughly 200 PS (197 hp) in European tune; US-spec cars were detuned for emissions
MB	2,226cc (2.2L)	SOHC, 10-valve	1987-1989	Larger-displacement follow-up to the WR, European market only by this point
RR	2,226cc (2.2L)	DOHC, 20-valve	1989-1991	Final and most powerful factory engine, around 220 PS (217 hp); US import had already ended before this engine arrived

Because official US sales stopped after the 1986 model year, the 20-valve RR engine and the Torsen-equipped Quattro II drivetrain were never sold new in America. Nearly every US-titled Quattro on the road today, and every real US-market VIN referenced on this page, is a 10-valve WR-engined, manually-locking Quattro I car.

None of this happened in a vacuum. Audi built the Quattro specifically to exploit rallying’s Group 4 regulations, and when the FIA introduced Group B for 1982, the car and its later Sport Quattro derivative became the benchmark the rest of the field had to answer. Hannu Mikkola and Arne Hertz gave four-wheel drive its first World Rally Championship win at the 1981 Swedish Rally, and Michele Mouton followed that same year by winning the San Remo Rally, the first win for a female driver and co-driver crew in WRC history. Audi took the manufacturers’ title in 1982, Mikkola took the drivers’ title in 1983 (the first for a four-wheel-drive car), and Audi swept both the drivers’ title (Stig Blomqvist) and the manufacturers’ title again in 1984. The factory team withdrew from top-level rallying after the 1986 season, when Group B itself was banned following a string of fatal accidents across the category, but the point had already been made: four-wheel drive was no longer optional at the front of a rally stage, and quattro became Audi’s permanent AWD badge as a direct result.

WMI codes for the US-imported Audi Quattro

The first three characters of a VIN are the World Manufacturer Identifier, assigned by SAE on behalf of ISO. Every genuine US-titled Audi Quattro VIN checked for this guide carries the same code:

WMI	Country	Manufacturer	Confirmed on
WAU	Germany	Audi AG	1983, 1984, and 1985 US-market Quattro coupes, all Ingolstadt-built

That WMI is verified directly against NHTSA’s vPIC decoder using real, checksum-valid US production VINs, including a 1983 car (WAUDC085XDA900328), a 1984 car (WAUDC085XEA900895), and a 1985 car (WAUDC0854FA900909), each sourced from public auction listings on Cars & Bids and Classic.com. All three decode cleanly through NHTSA’s system, with the check digit at position 9 confirmed correct on every one, BodyClass returned as “Coupe,” EngineCylinders returned as 5, and PlantCity returned as “Ingolstadt, Germany.” As with the shared-platform Coupe, NHTSA’s Model field lists these cars as “4000” rather than “Quattro,” an artifact of how the Typ 85 chassis was folded into Audi’s own sedan-era submissions to the agency; treat that field as a database quirk, not a description of the actual car.

European-market Quattros use a different-looking but related VIN convention, with a placeholder “ZZZ” at positions 4 through 6 and the internal type code “85” at positions 7 and 8, for example WAUZZZ85ZDA901303. US titling law required real content in that block instead, which is exactly what the three verified US VINs above show.

How to read a VIN: position by position

Every Audi Quattro built from its earliest model years forward follows the 17-character ISO 3779 standard used across the auto industry.

Positions 1-3: World Manufacturer Identifier

See the table above. Every real, US-titled Quattro VIN gathered for this guide begins WAU, identifying Audi AG of Germany. A VIN on a car represented as a genuine Quattro that does not begin with WAU (or the European WAUZZZ85 pattern) is worth treating with suspicion.

Positions 4-8: Vehicle Descriptor Section (VDS)

On a real US-market Quattro this reads “DC085” across all three verified model years (1983, 1984, and 1985), where “85” reflects the Typ 85 internal designation the car shares with the quattro-badged version of the B2 Coupe. Audi never published a public key mapping this block to specific options, so the tool above cross-references it against known production data rather than decoding it character by character.

Position 9: Check digit

Calculated from the other 16 characters through a fixed weighting table and modulo-11 math, this single character catches most single-digit typos. Every real US-market Quattro VIN referenced on this page returns a correctly computed check digit from NHTSA’s own decoder. European-market cars sometimes carry an uncalculated “Z” placeholder here instead; a genuine US-titled car should not.

Position 10: Model year

The 10th character maps to model year on the industry-wide 30-year cycle. For the Audi Quattro, the relevant span runs from 1981 through 1991:

Char	Year	Char	Year	Char	Year
B	1981	F	1985	K	1989
C	1982	G	1986	L	1990
D	1983	H	1987	M	1991
E	1984	J	1988

I, O, and Q are never used, since they can be misread as 1 and 0. Our three real, NHTSA-verified US-market VINs decode to “D” (1983), “E” (1984), and “F” (1985), matching their documented model years exactly. The US import window closed after model year 1986 (character “G”); we could not locate a real, federalized US-titled VIN carrying that letter, and most 1986-dated Quattros found in the US market today turn out to be later private imports of European-spec cars rather than part of the original 664-unit run, so treat any 1986 “G” US-titled VIN with extra scrutiny against the paperwork. Model years 1987 through 1991 (H through M) exist only on European-market cars, since Audi had stopped official US sales by then; those cars typically carry the “ZZZ” placeholder pattern described above rather than a US-style VDS. Independent enthusiast production records also note that Audi briefly used the letter “A” for a small number of pre-production Quattros built in the first weeks of July 1980, before switching to “B” for the bulk of what is generally called the 1981 model year; those handful of cars sit outside the standard range covered here and are best treated as pre-production examples.

Position 11: Assembly plant

A single character narrows the VIN to a specific factory. Every real VIN gathered for this guide reads the same way:

Char	Plant	Confirmed on
A	Ingolstadt, Germany	All three verified 1983-1985 US-market Quattro VINs

Ingolstadt was Audi’s sole factory for the Quattro across its entire eleven-year production run. Every verified VIN checked here confirms plant character “A,” with NHTSA’s PlantCity field independently returning “Ingolstadt, Germany.”

Positions 12-17: Serial number

The final six characters are the production sequence stamped on that specific car as it left the line, making the full 17-character string unique to one physical vehicle. Real US-market examples verified for this guide run in the 900000 range (900191, 900328, 900895, 900909), consistent with the small, sequentially numbered US-import batch within Audi’s larger worldwide production run. A serial number wildly outside that range on a car claimed to be part of the original US import is worth a closer look.

Where to find the VIN

• Stamped into the front body panel or firewall, visible with the hood open, the hardest of the four to alter
• Driver’s side door jamb or B-pillar data sticker, showing paint and equipment codes alongside the VIN
• Lower-left corner of the windshield, visible from outside the car, though not consistently applied on every early example
• Vehicle title, registration documents, and, for cars still carrying European paperwork, the Certificate of Conformity

Given how valuable and how frequently modified original Quattros have become, the engine-bay stamp is the one to check against the door sticker and the title before buying; it is welded into the body shell and far harder to alter than a printed label.

Check recalls and safety information

For the model years the Quattro was sold new in the US (1983 through 1986), NHTSA’s recall database is the primary source for open safety campaigns. Remember the quirk noted above: NHTSA’s own records sometimes file these cars under “Audi 4000” in the Model field rather than “Quattro,” so it is worth searching both terms.

For European-market Quattros never sold new in North America, including every 1987 through 1991 example, NHTSA’s system will not return meaningful recall data, since the car was never certified for US sale in those years. The manufacturer recall register maintained by Audi AG, along with the Kraftfahrt-Bundesamt in Germany, is the primary source for open campaigns on those cars.

To check a specific car:

1. Decode the VIN with the tool above to confirm the model year and confirm it matches a genuine Typ 85 chassis
2. For a US-market 1983-1986 Quattro, cross-reference the VIN with NHTSA’s recall database, trying both “Quattro” and “4000” as the model
3. For a European-market car, check with an Audi-authorized service center or the Kraftfahrt-Bundesamt
4. Before buying, review our guide on checking if a car is stolen by VIN; cars this rare and this valuable are a genuine target for VIN cloning and title washing

Recall repairs are free regardless of vehicle age, mileage, or ownership history, though parts availability for a car this old and this low in production volume is a real practical constraint independent of the recall itself.

Frequently asked questions

Was the Audi Quattro sold in the United States?

Yes, but only in small numbers and for a short window. Audi officially imported the Quattro to the US for model years 1983 through 1986, roughly 664 units total, plus about 99 more sold in Canada. Every real US-market VIN pattern referenced on this page is verified against NHTSA’s vPIC database. By comparison, Audi built about 11,452 Quattros worldwide across the model’s full 1980-1991 run, meaning the US-market cars represent under six percent of total production.

Why is “quattro” the name for Audi’s all-wheel-drive system today?

Because this car invented it as a name, not just as a badge. “Quattro” is simply Italian for “four,” referring to the four driven wheels, and Audi trademarked it as the model name for this specific coupe in 1980. The name proved so closely tied to the technology in buyers’ minds that Audi kept using it, lowercase, as the brand name for every all-wheel-drive system and every AWD variant of every model it has sold since, from the A4 quattro to the R8 quattro. The original 1980s coupe is why the word appears on Audis at all.

What made the Audi Quattro significant in rally racing?

It proved permanent four-wheel drive worked at the top level of motorsport, then forced every rival manufacturer to copy the idea or lose. Hannu Mikkola gave it the first World Rally Championship win for a four-wheel-drive car at the 1981 Swedish Rally, Michele Mouton took the first win by a female driver and co-driver crew later that year at San Remo, and Audi won the manufacturers’ title in 1982 and 1984 and the drivers’ title in 1983 and 1984. The Group B era it helped define ended after the 1986 season on safety grounds, but by then rally cars without four-wheel drive were effectively obsolete.

What is the Torsen differential, and does every Quattro have one?

No. Only later cars do. Every Quattro built through the 1987 model year used an open center differential the driver had to lock manually with a dashboard switch. Starting with the 1988 model year, Audi switched to a Torsen type 1 center differential that split power automatically without driver input. Since US import ended after 1986, no factory-original US-market Quattro carries the Torsen setup; it is a European-only, later-production feature on this particular model.

What is the difference between the Audi Quattro and the Audi Coupe?

They share a body shell but are different cars aimed at different buyers. The standard Audi Coupe and Coupe GT (Typ 81) were front-wheel-drive, naturally-aspirated everyday cars built on the same B2 platform. The Audi Quattro (Typ 85) used the same shell but added permanent all-wheel drive and a turbocharged engine, sold as its own distinct, low-volume performance model. See the Audi Coupe VIN decoder for the front-wheel-drive car’s own generation history and VIN detail.

How do I decode an Audi Quattro VIN?

Type the 17-character VIN from the firewall stamp, door jamb, or title into the decoder above. It returns model year and plant in seconds for genuine US-market cars. European-market Quattros, especially the later Torsen-equipped, 20-valve examples never sold new in North America, return more limited results, since NHTSA’s database is built around vehicles certified for US sale.

Is the Audi Quattro VIN decoder really free?

Yes, with no sign-up, covering everything the factory stamped into the VIN. A full vehicle history report, covering accidents, odometer readings, and prior ownership where records exist, is a paid upgrade for cars with a North American title history. Given how often Quattros of this era carry import paperwork rather than a clean domestic chain of title, a VIN decode and a vehicle history report answer different questions, and it is worth understanding what each one actually covers before you rely on it.
