Frequently Asked Questions

Find answers to common questions about torque specifications

What type of drivetrain does the 2012-2015 Audi RS4 use?

The 2012-2015 Audi RS4 features a quattro all-wheel-drive (AWD) system with a self-locking center differential. This system distributes torque with a default 40:60 front-to-rear split, but can dynamically adjust up to 70:30 or 15:85 depending on driving conditions.

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

The drivetrain is designed to handle up to 430 Nm (317 lb-ft) of torque, which is the maximum output of the 4.2-liter V8 FSI engine. The system is engineered to ensure optimal power delivery and durability under high-performance conditions.

How does the quattro system improve handling in the RS4?

The quattro system enhances handling by continuously monitoring wheel speeds, steering angle, and lateral acceleration. It adjusts torque distribution to maximize traction and stability, particularly during cornering, acceleration, and low-grip conditions.

What type of transmission is paired with the drivetrain?

The 2012-2015 Audi RS4 is equipped with a 7-speed S tronic dual-clutch transmission. This transmission provides rapid gear shifts and seamless power delivery, complementing the quattro AWD system for optimal performance.

What is the recommended service interval for the drivetrain components?

Audi recommends inspecting the drivetrain components, including the differential and driveshafts, every 30,000 miles or 2 years, whichever comes first. Regular maintenance ensures longevity and performance, especially under high-stress driving conditions.
