Significance: A one-off Sport quattro reconstructed and extensively modernized by quattro GmbH for a prominent Middle Eastern client. Former quattro GmbH development chief Stephan Reil identified chassis No. 144 as the first of the subsidiaryโs specialized restoration and upgrade commissions, making it an early example of the bespoke vehicle-engineering work later associated with Audi exclusive and Audi Sport GmbH.

OVERVIEW
Audi Sport quattro chassis No. 144 is a one-off road car extensively reconstructed and modified by quattro GmbH for a prominent Middle Eastern client. Although based on a production 1984 Sport quattro, the car received substantial mechanical, chassis, exterior and interior changes intended to modernize its performance and usability while retaining the essential character of the original homologation model.
The project was described in its 2011 sales listing as the only factory-produced โSport quattro Evo 2.โ That was not an official Audi model designation, nor was the car a continuation of Audi Sportโs Group B development program. Its work was nevertheless performed by Audiโs own quattro GmbH subsidiary and documented through original invoices, engineering work, test-bench development and subsequent homologation.
Former quattro GmbH development chief Stephan Reil identified chassis No. 144 as โJob 1,โ the first of the companyโs specialized restoration and major-upgrade commissions. It should not be confused with quattro GmbHโs first activities overall, which began with accessories and branded merchandise following its establishment in 1983, or with its first complete production car, the Audi S6 plus introduced in 1996.
ORIGINAL CAR
Chassis No. 144 was one of approximately 214 Sport quattros constructed for competition homologation and road use. Contemporary research associated with the car indicated that approximately 164 were sold as road cars to private customers.
The car was originally painted Copenhagen Blue and registered in France. By the time it returned to Audi, it had accumulated approximately 21,000 kilometers (13,049 miles). Documentation suggests the body may also have required repair, although the precise circumstances and extent of any damage have not been confirmed.
The clientโs identity was withheld at his request. Original paperwork addressed correspondence to the โSecretariat de Son Altesse,โ or Secretariat of His Highness, and identified the customer as a prince.

QUATTRO GMBH COMMISSION
The surviving cost summary refers to an offer dated December 23, 1998, followed by additional expenditure approved after the client inspected the project on January 31, 2000. The final quattro GmbH invoice is dated June 30, 2000.
The invoice described the principal work as โRestauration Audi quattro Sport schwarzโโrestoration of a black Audi Sport quattro. The base project cost DM 299,500, with a further DM 75,000 charged for additional work agreed after the January inspection.
The resulting subtotal was DM 374,500. With 16-percent value-added tax of DM 59,920, the invoice totaled DM 434,420, equivalent at the time to โฌ222,115.42. Separate road-tax and third-party insurance charges brought the documented grand total to DM 439,114.90.
This was not a conventional restoration intended to return the car to its original specification. quattro GmbH rebuilt the Sport quattro as a comprehensively modernized one-off, repairing or recreating unavailable components while developing new systems around the clientโs requirements.

ENGINE AND EXHAUST
The original Sport quattro engine was overhauled and modified to produce approximately 345 bhp. The work included replacing the original aluminum cylinder block with a cast-iron block, installing a new turbocharger with altered geometry and revising the boost-pressure regulation.
quattro GmbH also tailored the engineโs power curve and modified the exhaust with a different final or secondary silencer. Reil later described the resulting exhaust note as โelectrifying.โ
The engine work accounted for DM 55,000 of the documented project cost.
TRANSMISSION AND STEERING
The drivetrain received a new gearbox with the adaptations required for installation in the Sport quattro. The gearbox work was invoiced at DM 15,000.
A new steering box was also installed and adapted to the car at a documented cost of DM 4,000.
Although the modifications substantially updated the car, the permanent quattro all-wheel-drive system and manual-transmission configuration remained central to its specification.
CHASSIS, WHEELS AND BRAKES
quattro GmbH developed and adapted a stiffer suspension for the car, including revised shock absorbers and calibration for 17-inch wheels. The cost summary explicitly lists both tires and rims within the DM 21,000 running-gear work.
According to Reil, quattro GmbH commissioned a very limited run of 17-inch wheels reproducing the appearance of the Sport quattroโs original Ronal design. The 2011 sale reportedly included unused road wheels and a separate set described as racing wheels.
The modular five-spoke wheels fitted when the car was advertised in 2011 do not appear in the quattro GmbH invoice and may have been installed later.
The brake system was extensively redeveloped to suit the larger wheels and increased performance. Work included new front and rear calipers and pistons, new front and rear discs, revised pads and a brake-force distributor adapted to work with the anti-lock braking system. These changes were invoiced at DM 18,000.
The 2011 seller described the brakes as being derived from the Audi RS 6. Because the quattro GmbH project was invoiced two years before the first RS 6 entered production, that description may refer to later work or components subsequently associated with the RS 6 rather than the original 2000 installation.

BODY AND EXTERIOR
The body was repaired and refinished in black according to the clientโs brief. Work covered the exterior and interior paint, sheet metal, fiberglass and carbon-fiber components, underbody and wheel arches.
Audi produced only two Sport quattros in black as part of the original production run. Those cars have long been associated with Ferdinand Piรซch and Walter Rรถhrl. Chassis No. 144 was not one of those original black cars, but its quattro GmbH color change gave it a similar appearance.
Several functional changes distinguished the rebuilt car from a standard Sport quattro. A replacement hood incorporated additional ventilation louvers near the base of the windshield, while a roof-mounted antenna appears to have been added as part of the upgraded communications or audio equipment.
Additional driving lights were integrated into shortened cross-hatch grille sections using housings resembling those fitted to the original long-wheelbase quattro. The principal headlights were converted to H4 units with what the invoice described as โspecial rally internals.โ
Body and paint work totaled DM 22,500, while the lighting conversion added DM 2,500.

INTERIOR
The original brown cabin was comprehensively rebuilt in black leather and Alcantara. quattro GmbH restored the original components, repaired underlying structures where necessary and optimized trim pieces to accept the new coverings.
The factory Recaro seats were retrimmed in black leather, while the diagonal upholstery pattern on the door panels was retained. The Sport quattroโs unique dashboard, including its three auxiliary instruments above the center console, was covered in stitched black leather.
The car also received Sabelt competition harnesses with homologated mounting points, an updated steering wheel and mobile-telephone equipment. Its original steering wheel was reportedly retained with the car.
An aftermarket-style silver radio head unit was visible when chassis No. 144 was advertised in 2011. The surviving invoice does not identify that particular unit, making it unclear whether it was fitted during the quattro GmbH reconstruction or added later.
The interior work accounted for DM 52,000 of the documented cost.
AIR CONDITIONING
quattro GmbH developed and adapted a manually controlled air-conditioning system for the car. The installation included a specialized cooling-unit compressor and associated cowling.
This was a substantial engineering project rather than the installation of a standard production-car system. It added DM 23,000 to the cost of the rebuild and likely reflected the climate in which the owner intended to use the car.
REPLACEMENT PARTS
The project required quattro GmbH to obtain new original parts where they remained available. When components could no longer be sourced or repaired, replacements were designed from original patterns and fabricated by hand.
This work was assigned a separate cost of DM 50,000 and demonstrates the extent to which the commission combined restoration with bespoke engineering.
TESTING AND HOMOLOGATION
The car underwent laboratory investigation, test-bench development and approximately 150 hours of workshop testing. The documented workshop and laboratory work cost DM 21,500.
A further DM 15,000 was allocated to regulatory testing and certification. The documentation lists approval work covering engine performance, exhaust emissions, noise, brakes, wheels and tires under the applicable European standards.
The car later received French individual-type approval on January 16, 2004. The approval identified it as an imported vehicle that did not conform to an established French type and recorded the commercial name as Audi Quattro, type 85KW2Q and chassis number WAUZZZ85ZEA905144.
A SECOND COMMISSION
Stephan Reil, who worked at quattro GmbH from its earliest years and later led the companyโs technical development, recalled that the project led to a second Sport quattro commission. Later information identifies that car as chassis 905083 and the customer as Prince Rahim Aga Khan, the eldest son of Aga Khan IV and, since 2025, Aga Khan V and the 50th hereditary Imam of the Shia Ismaili Muslims.
Chassis 083 was originally Tornado Red but emerged from quattro GmbH in blue with a cream leather interior, increased engine output, air conditioning, upgraded brakes and five-spoke wheels similar to those installed on chassis 144. It remained with Prince Rahim until 2022 and was subsequently sold by Schaltkulisse. The companyโs listing attributes several costs and technical details to chassis 083 that closely duplicate surviving paperwork explicitly identifying chassis 144, however, so the precise scope and cost of the second conversion remain uncertain.

RETURN TO THE MARKET
Chassis 144 returned to the market in 2011, when it was offered in the black specification created by quattro GmbH. It retained the retrimmed interior, upgraded engine, larger brakes, air conditioning, supplementary harnesses, aftermarket audio system and MOMO steering wheel. The car was then fitted with the five-spoke wheels carrying Audi center caps consistent with wheels seen on the second blue car when it came up for sale suggesting these were the original 17-inch wheels fitted by quattro GmbH.
The car appeared for sale again through RaceCarsDirect in 2016. By then, the earlier five-spoke wheels had been replaced by white Compomotive MO5 wheels. The advertisement identified the car as number 144 of 214, showed 35,873 kilometers and listed an asking price of โฌ395,000 plus VAT. It described the engine as producing approximately 350 hp and identified the brakes as RS 6 components. The advertisement was subsequently marked sold, although the transaction date and buyer were not disclosed.
Some of the chronology in the advertisement is incorrect. It states that the car was sent to quattro GmbH in 2004, while the surviving records show that the project began during the late 1990s and was invoiced in June 2000. The listing elsewhere describes the work as having been completed in 2001.
RETURN TO COPENHAGEN BLUE
By January 2022, chassis 144 had undergone another comprehensive restoration, this time by Bourguignon Classics in the Netherlands. Before-and-after photographs published by the company on Facebook showed that the black finish had been removed and the car returned to its original Copenhagen Blue. Bourguignon also stated that the leather interior had been returned to its original configuration and that the remainder of the car had been fully restored.
The photographs show a substantially factory-style grey interior in place of the black leather and Alcantara treatment commissioned from quattro GmbH. The supplementary harnesses and aftermarket audio equipment appear to have been removed. The MOMO steering wheel fitted during the black-car period was replaced by a MOMO Race wheel, rather than the original Sport quattro steering wheel.
Bourguignon also replaced the white Compomotive MO5 wheels shown in the 2016 advertisement with unidentified 9×16 5-spoke wheels similar in appearance to the Compomotives that are themselves similar to the original 16-inch Speedline wheels used by Audi Sport in Group B competition on tarmac. Although visually similar, the wheels can be distinguished by their cast markings and embossed logo. Close-up photographs show the larger upgraded brake calipers and rotors still installed behind them, indicating that at least part of the quattro GmbH mechanical specification survived the restoration.
Bourguignon did not publish a detailed mechanical account of the work. It therefore remains unknown whether the upgraded engine, gearbox, steering, suspension, exhaust and air-conditioning system were retained or returned to standard specification. The available photographs suggest that the restoration concentrated on returning the carโs exterior color and interior substantially toward their original appearance rather than completely undoing the quattro GmbH conversion.
ARCHIVAL RENDERINGS
The associated archival renderings reconstruct chassis No. 144 as best we can following its quattro GmbH transformation. Given the consistency of the 17-inch wheels on both cars as they eventually came to market, we have kept those wheels shown on the car.
The car is shown in black with its documented body changes, additional hood ventilation, roof antenna and integrated auxiliary lights.

SIGNIFICANCE
Sport quattro chassis No. 144 occupies an unusual position between Audiโs competition history, quattro GmbHโs bespoke work and the modern remaster movement.
It was not an Audi Sport competition prototype, a previously unknown Group B evolution or an official โEvo 2โ production model. It was instead an extensively re-engineered road-going Sport quattro commissioned by a private client and executed by Audiโs own high-performance subsidiary.
The project anticipated the type of individualized engineering, restoration and component recreation now commonly associated with factory heritage programs and high-end remasters. Its documented quattro GmbH provenance makes it more than a modified Sport quattro and provides a rare view into a largely undocumented area of the subsidiaryโs history.
As โJob 1,โ it also represents an early expression of the bespoke capabilities that would later help define quattro GmbH and its successor, Audi Sport GmbH.
Interestingly, the car predates modern factory commissions of restorations as we see today at Porsche, Land Rover and other brands. Nevertheless, Audi’s own activities in this space remains exceptionally rare. This makes this particular Sport quattro both one-of-one and a highly unique demonstration of work not typically taken on by quattro GmbH.
