What does quattro mean?
2 Answers
quattro refers to Audi's four-wheel drive technology, which is a permanent four-wheel drive mode that maintains four-wheel drive status under any circumstances. Its core four-wheel drive technology is the torsen central differential. This differential adopts a worm gear planetary gear structure and operates purely mechanically without the need for electronic system intervention. The working principle of quattro is: when a speed difference between the front and rear axles occurs due to external conditions, the torsen differential automatically transmits most of the energy to the drive axle capable of working, optimizing and distributing power to the four wheels automatically. Due to the balanced distribution of axle load, the driver can better control the precision and flexibility of steering without the need for torque steering assistance.
quattro is Audi's full-time four-wheel drive technology, named after the Italian word for "four," representing all four wheels being driven. This system automatically distributes power to each wheel. For example, on slippery roads, when it detects a wheel losing traction, it transfers more torque to the wheels with better grip, enhancing stability and traction. When driving an Audi in rain or snow, quattro makes the car feel glued to the road, preventing skidding or loss of control. The core of the system lies in the collaboration between the central differential and sensors, which monitor vehicle speed, steering angle, and road conditions to adjust power distribution in real time. Originally designed for rally racing, this technology is now available across all Audi SUVs and sedans, significantly improving handling. For everyday driving, choosing a quattro model ensures peace of mind when facing unexpected road conditions, especially enhancing safety during long trips. Maintenance requires regular checks of transmission fluid and the differential, but the system is generally reliable and durable.
