Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 2017-Present Audi RS3 use?

The 2017-Present Audi RS3 features a quattro all-wheel-drive (AWD) system with a multi-plate clutch. This system provides a default torque distribution of 50:50 between the front and rear axles but can dynamically adjust up to 100% torque to either axle based on driving conditions.

What is the torque capacity of the RS3's drivetrain?

The Audi RS3's drivetrain is designed to handle up to 500 Nm (369 lb-ft) of torque, which is well-suited for the 2.5-liter TFSI inline-5 engine producing 400 Nm (295 lb-ft) of torque in stock configuration.

How does the quattro system in the RS3 improve performance?

The quattro system enhances traction, stability, and performance by continuously monitoring wheel slip and adjusting torque distribution. It also features a sport differential that can vector torque between the rear wheels, improving cornering agility and reducing understeer.

What type of transmission is paired with the RS3's drivetrain?

The Audi RS3 is equipped with a 7-speed S tronic dual-clutch transmission (DCT). This transmission provides rapid gear shifts, optimized for both performance and efficiency, and supports launch control for maximum acceleration.

Can the RS3's drivetrain handle aftermarket performance upgrades?

While the drivetrain is robust, significant aftermarket upgrades (e.g., increased torque beyond 500 Nm) may require additional modifications to the clutch, differential, or transmission components. Always consult with a certified Audi technician to ensure compatibility and avoid voiding the warranty.
