Audi Audi A8 2010-2017 Drivetrain Specifications

The 2010-2017 Audi A8 is equipped with a quattro all-wheel-drive (AWD) system. This system uses a Torsen (Torque-Sensing) center differential to distribute torque between the front and rear axles, with a default 40:60 front-to-rear torque split. The system can dynamically adjust torque distribution based on driving conditions, up to 70% to the front or 85% to the rear.

Audi recommends inspecting the drivetrain components, including the differential and driveshaft, every 40,000 miles or 4 years, whichever comes first. The transmission fluid and differential oil should be replaced every 60,000 miles or 6 years to ensure optimal performance and longevity.

The quattro system is a complex integrated system, and repairs should only be performed by certified Audi technicians. While some components, such as the driveshaft or differential seals, can be serviced independently, issues with the Torsen differential or electronic control systems require specialized diagnostic tools and expertise.

The drivetrain in the 2010-2017 Audi A8 is designed to handle up to 650 Nm (479 lb-ft) of torque, depending on the engine variant. The 4.0 TFSI V8 and 6.3 W12 models are specifically engineered to manage higher torque outputs, ensuring durability under high-performance conditions.

Common issues include wear and tear on the driveshaft center support bearing, differential fluid leaks, and occasional electronic faults in the quattro system. Regular maintenance and using genuine Audi parts can mitigate these issues. If unusual noises or vibrations are detected, immediate inspection is recommended.
