Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What type of drivetrain does the 2018-Present Audi Q8 use?
What type of drivetrain does the 2018-Present Audi Q8 use?
The Audi Q8 is equipped with a quattro all-wheel-drive system, which utilizes a self-locking center differential with a default torque split of 40:60 (front:rear). This system can dynamically redistribute torque based on driving conditions, with up to 70% to the front or 85% to the rear as needed.
Q2 What is the maximum torque capacity of the Audi Q8's drivetrain?
What is the maximum torque capacity of the Audi Q8's drivetrain?
The drivetrain in the Audi Q8 is designed to handle up to 600 Nm (442 lb-ft) of torque, depending on the engine variant. For example, the 3.0 TFSI engine produces 500 Nm (369 lb-ft) of torque, while the SQ8's 4.0 TFSI engine delivers up to 800 Nm (590 lb-ft) in performance-oriented models.
Q3 Does the Audi Q8 drivetrain support off-road driving?
Does the Audi Q8 drivetrain support off-road driving?
Yes, the Audi Q8's quattro all-wheel-drive system, combined with adaptive air suspension and drive select modes, provides excellent off-road capability. The system includes hill descent control and can adjust ground clearance from 152 mm to 254 mm, ensuring optimal performance on uneven terrain.
Q4 What is the service interval for the drivetrain components?
What is the service interval for the drivetrain components?
Audi recommends inspecting the drivetrain components, including the differential and transfer case, every 30,000 miles or 3 years, whichever comes first. Fluid changes for the differential and transfer case are typically required every 60,000 miles or 6 years, depending on driving conditions.
Q5 Can the Audi Q8 drivetrain be modified for higher performance?
Can the Audi Q8 drivetrain be modified for higher performance?
While modifications are possible, they may void the vehicle's warranty and compromise safety. Audi offers performance upgrades through its Audi Sport division, such as the SQ8 and RS Q8 models, which feature enhanced drivetrain components and higher torque capacities.
