Cool Facts about the Audi A6 Quattro

  • The Audi A6 line of vehicles made it to Car & Driver's Ten Best list twice. It did this in two consecutive years, 2000 and 2001. A year after its last award, it received a facelift, with revised headlight and grille design, exposed exhaust tips, slight changes to accessory body moldings, and taillight color from red to amber in North American models.

  • Based on a rating by the Insurance Institute for Highway Safety (IIHS) in the United States, the Audi A6 Quattro is currently the safest car in the world. In a research done by the committee, not a single fatality has been recorded in an Audi A6 Quattro since 2005.

  • Quattro is the name used by Audi AG to refer to its all-wheel drive (AWD) technologies or systems that are used on certain models of Audi vehicles. It means four in Italian, referring to the four wheels of a car. It is a registered trademark of Audi AG under Volkswagen Group and is spelled with a lower case q due to nomenclature rights derived from the trademark. The quattro was first introduced in 1980 on the permanent four-wheel drive Audi quattro, and was eventually given to all subsequent AWD models-including the Audi A6 quattro.

  • The quattro system is based on the Torsen (torque sensing) T1 centre differential technology, which replaced Audi's manually locking centre differential in 1987. The Torsen T1 system was proactive and had an element of fail-safe, but it was eventually replaced by the Torsen T3 centre differential technology due to some limitations. The T3 technology was eventually applied in longitudinal-engined quattro-equipped cars, including the A6 quattro.

  • The quattro technology has evolved over the years since its inception. Every time a new version was debuted, however, it was not tied to a specific model and year. Rather, new developments in the quattro technology were applied to a series of vehicles within a specific period until improvements come along. The Audi A6 quattro is equipped with the Generation IV quattro system.

  • Audi shares the same city with BMW as its headquarters-it is set up in Bavaria, Germany. Even with its German roots, however, Audi is named after a Latin word meaning hark or listen. Its logo is a representation of four companies that merged to form Audi AG: Audi, DKW, Horch, and Wanderer.

  • Common Troubles of the Audi A6 Quattro

    The Audi A6 is a series of executive cars manufactured by Volkswagen-owned manufacturer Audi AG, starting with a mid-size car in 1994 and continuing to the present with a hybrid electric car. In 1999, a semi-offroad model was released as the Audi Allroad quattro, but it wasn't until 2005 that Audi redesigned and renamed the vehicle Audi A6 quattro. It had a few off-road styling cues including larger bumpers and sills and had remarkable sporty performance and operating convenience. It was plagued, however, with a few faults that prompted some recalls. Here are some of them.

    Curtain airbags

    Problems with the stitching process on the curtain airbag's seams have been reported in late 2011. Manufacturing faults like these pose a great risk to passenger safety in the event of a crash. A head curtain airbag may not even deploy during a crash because of this. Audi recalled around 300 A6 quattros and replaced the curtain airbags affected free of charge.

    Fuel tank rollover valve

    A defective fuel tank rollover valve can cause serious problems to the vehicle. A significant number of Audi A6 quattro units are affected by this problem, attributed to the material the fuel tank rollover valve is made from. The aging of the plastic material and the stress from the aluminum ventilation line may lead to cracking of the connection nipple. Ultimately, the damaged nipple could leak fuel, which could then lead to fire.

    Audi recalled a number of A6 quattros in 2011 and reinforced the connection nipple on the rollover valve. Cracked connection nipples were repaired as necessary.

    Electrical system

    Some A6 quattros are observed to produce an electrical short that could potentially start a fire. Apparently, the A6 was designed with a weak knee bolster. When the driver's knees push against it, the wiring harness located under the dashboard may be disturbed and an electrical short can occur. The NHTSA, after observing this seemingly minor flaw, suggested that dealers install a protective covering on the knee bolster. Also, they need to check both the wiring harness and the felt protector on the left side of the dashboard for damage and replace either or both them if necessary.
