Audi Audi Q3 2011-2018 Drivetrain Specifications

The 2011-2018 Audi Q3 is equipped with a quattro all-wheel-drive (AWD) system. This system uses a Torsen (Torque-Sensing) differential to distribute torque between the front and rear axles, with a default 40:60 front-to-rear torque split under normal driving conditions. The system can dynamically adjust torque distribution up to 100% to either axle based on traction needs.

The Audi Q3's drivetrain is designed to handle a maximum torque output of up to 400 Nm (295 lb-ft), depending on the engine variant. The 2.0 TFSI engine, for example, produces 320 Nm (236 lb-ft) of torque, while the 2.0 TDI engine generates up to 380 Nm (280 lb-ft).

Audi recommends inspecting the drivetrain components, including the driveshafts, differential, and transfer case, every 30,000 miles or 24 months, whichever comes first. Regular inspections help identify wear, leaks, or damage to ensure optimal performance and longevity.

The rear differential in the Audi Q3 requires Audi-approved synthetic gear oil, typically SAE 75W-90 GL-5 specification. The fluid capacity is approximately 1.2 liters (1.3 quarts). Always use genuine Audi fluid to maintain performance and warranty compliance.

No, the quattro all-wheel-drive system in the Audi Q3 is always active and cannot be manually disabled. The system continuously monitors driving conditions and adjusts torque distribution automatically to optimize traction and stability.

The Haldex clutch, used in the quattro system for torque distribution, requires servicing every 30,000 miles or 3 years. This includes replacing the Haldex fluid and cleaning the filter to ensure proper operation and prevent premature wear.
