What is the Kuachuo car?

Kuachuo refers to Audi's all-wheel-drive system 'quattro', which is the Chinese pronunciation of the English term. Origin of Kuachuo: Audi's quattro technology originated in 1980, with the first model equipped with the quattro system also named quattro. The earliest first-generation quattro system featured an open center differential (manually lockable) + front open differential + rear open differential (manually lockable) structure. The first-generation quattro all-wheel-drive system had a differential installed at the rear of the transmission, driven through a hollow driveshaft, which transmitted power to the front differential. A driveshaft was also installed at the rear of the center differential to transfer engine power to the rear differential. This eliminated the need for a bulky and heavy transfer case, effectively solving space issues. Advantages of Kuachuo: Unlike conventional part-time four-wheel-drive systems or differential locks that incorporate electronic controls, the quattro system is unique in that it handles tire slippage or traction force distribution through purely mechanical structures. Unlike typical electronically controlled all-wheel-drive systems, it efficiently distributes engine power to all four wheels at all times and works in conjunction with the Torsen mechanical center differential to ensure optimal road grip for all four tires. Compared to other four-wheel-drive systems with electronic control devices, this structure offers instantaneous response and adjustment, significantly enhancing vehicle stability, handling, and safety. This also makes Audi vehicles equipped with 'Kuachuo' excel in muddy or snowy conditions.
I have to say, 'Kuachuo' is actually Audi's quattro system. It's not a specific car model, but Audi's signature all-wheel drive technology. I know this can be quite confusing because I used to misunderstand it too. 'Kuachuo' comes from the transliteration of 'quattro'. Audi first introduced it in rally cars back in 1980. It automatically distributes power to all four wheels through a center differential, ensuring firm traction in any road condition. For example, during rain or snow, driving a car equipped with quattro feels particularly stable without any slipping. Nowadays, many Audi models feature upgraded versions like the electronically controlled quattro ultra, which is more fuel-efficient without compromising performance. In short, it's one of Audi's major highlights that enhances both safety and driving pleasure.
