Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 2018-Present Audi RS4 use?

The 2018-Present Audi RS4 features a quattro all-wheel-drive (AWD) system with a self-locking center differential. This system provides a 40:60 torque split between the front and rear axles under normal conditions, with the ability to dynamically adjust torque distribution based on driving conditions.

What is the torque capacity of the Audi RS4's drivetrain?

The Audi RS4's drivetrain is designed to handle up to 600 Nm (442 lb-ft) of torque, which is well-suited for the 2.9-liter TFSI V6 engine that produces 450 PS (444 hp) and 600 Nm of torque.

Can the Audi RS4's drivetrain be modified for higher performance?

While modifications are possible, they must be performed with caution. Upgrading components such as the differential or driveshafts requires precise engineering to maintain the integrity of the quattro system. Use of non-genuine parts or improper installation can lead to drivetrain failure and void the vehicle's warranty.

What is the recommended service interval for the Audi RS4's drivetrain components?

Audi recommends inspecting the drivetrain components, including the differential and driveshafts, every 30,000 miles or 2 years, whichever comes first. The transmission fluid should be replaced every 40,000 miles to ensure optimal performance and longevity.

How does the Audi RS4's drivetrain handle off-road conditions?

While the Audi RS4 is primarily designed for on-road performance, its quattro AWD system provides excellent traction in light off-road conditions. However, the vehicle's low ground clearance and sport-tuned suspension limit its capability in extreme off-road scenarios.
