Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 1999-2004 Audi S6 use?

The 1999-2004 Audi S6 features a permanent all-wheel-drive (AWD) system known as quattro. This system uses a Torsen (Torque-Sensing) Type 1 center differential, which distributes torque 50:50 under normal conditions but can adjust up to 75:25 front-to-rear or 25:75 rear-to-front depending on traction needs.

What is the gear ratio of the 6-speed manual transmission in the Audi S6?

The 6-speed manual transmission in the 1999-2004 Audi S6 has the following gear ratios: 1st gear - 3.500:1, 2nd gear - 2.118:1, 3rd gear - 1.517:1, 4th gear - 1.156:1, 5th gear - 0.939:1, 6th gear - 0.778:1. The final drive ratio is 4.111:1.

What is the torque capacity of the drivetrain components?

The drivetrain components of the 1999-2004 Audi S6 are designed to handle the engine's maximum torque output of 350 Nm (258 lb-ft) at 3,200 rpm. The Torsen differential and reinforced driveshafts ensure reliable power delivery under high-stress conditions.

How often should the drivetrain fluids be serviced?

Audi recommends replacing the transmission fluid and differential oil every 60,000 miles or 5 years, whichever comes first. Use only Audi-approved fluids, such as G 052 145 A2 for the transmission and G 052 145 S2 for the differential, to ensure optimal performance and longevity.

Can the quattro system be disabled or modified?

No, the quattro system in the 1999-2004 Audi S6 is a permanent all-wheel-drive system and cannot be disabled. Modifications to the drivetrain, such as aftermarket differentials or altered gear ratios, may void the vehicle's warranty and compromise safety.
