How to pronounce Audi's four-wheel drive in Chinese?
1 Answers
Audi's four-wheel drive is pronounced as 'Kuà Chuò' in Chinese, and quattro is the registered trademark of Audi's four-wheel drive technology. The core technology of the four-wheel drive is the Torsen central differential, which features a worm gear planetary gear structure and operates purely mechanically without the need for electronic system intervention. Compared to other differentials, the Torsen central differential can more promptly adjust the torque distribution between the front and rear axles, allowing power to be output from the planetary gears to drive both axles. During straight-line driving, the Torsen differential distributes power evenly at a 50:50 ratio between the front and rear axles, with the planetary gears inside the differential housing not rotating. When the car accelerates, due to increased rear wheel traction, the Torsen differential automatically allocates more power to the rear wheels to achieve greater effective traction. The Quattro system is characterized by excellent off-road capability, on-road performance, active safety, and response speed. Its drawbacks include greater weight, higher cost, and applicability only to longitudinally mounted engine models.
