ZF is a German brand, collectively known as one of the world's top three transmission distributors alongside Aisin and Getrag. The company is headquartered in Friedrichshafen, Germany, and holds a leading position in automotive powertrain systems and chassis technology. Due to ZF transmissions being more suitable for high-torque output in extreme environments, they are typically equipped in luxury vehicles. For instance, and Audi within the BBA group use ZF transmissions, as does the American Range Rover. Hence, ZF is often referred to as the "luxury vehicle-specific transmission." Usage of ZF transmissions: Shifting starts from the auxiliary box, then moves from the low-gear range to the high-gear range. Essentially, when shifting from low to high gears, there should be an interval operation—first allowing the auxiliary box to shift, followed by the main box. This transmission strictly prohibits coasting in neutral after the engine is turned off. Generally, maintenance should be performed after the vehicle has traveled 2,000 to 3,000 kilometers, including replacing the transmission gear oil. Oil changes should be done while the vehicle is warm, preferably using gear oil that meets the international standards API GL-4 grade, SAE 85W/90 viscosity. As early as the early 1980s, when thousands of Mercedes-Benz trucks equipped with ZF transmissions were introduced to oil fields in China's Northeast Xinjiang Autonomous Region, the ZF Group began quietly entering the Chinese market. ZF Group's representative office in China was established in Beijing in 1988. Today, in mainland China, the ZF Group has achieved significant growth, operating 17 production and assembly plants, 1 trading company, 1 regional headquarters (including an R&D center), and 2 sales service companies with comprehensive after-sales service networks (7 branches, 34 after-sales service outlets, and representative offices), employing approximately 2,300 people. The ZF Group has an excellent customer base in China, including Shanghai Volkswagen, Shanghai General Motors, FAW Group, Brilliance BMW, Sinotruk Group, Chery Company, King Long Company, Dongfeng Group, Soueast Motor, and others. Its products are widely used in passenger cars, buses, trucks, ships, and construction machinery vehicles.

















When chatting with friends about transmissions, I mentioned ZF, which is a brand with pure German heritage. It was founded in Friedrichshafen in 1915, and the name ZF is an abbreviation of the founder's name. I often encounter their products when repairing cars, ranging from small steering gears to large truck transmissions. The Germans really have a knack for precision machinery. They have over 400 locations worldwide, with production bases in Shenyang and Zhangjiagang in China. The 8AT transmission we replaced in the shop last year was from ZF, and its shifting logic is much smarter than some Japanese brands.

I remember once helping a customer modify chassis components, and upon disassembly, we discovered it was a ZF electronic steering system. This brand originates from Baden-Württemberg, Germany, and is considered a century-old establishment. They initially manufactured aircraft gears and even produced tank transmissions during WWII. Nowadays, they're most famous in the passenger vehicle sector for their 8HP transmission series. Interestingly, they acquired WABCO just a couple years ago to expand into commercial vehicle braking systems. German luxury brands like , Mercedes, and Audi all extensively use their components – particularly that magical carpet ride technology with their electromagnetic suspension, which delivers remarkable stability.

Last week I went to the auto parts market looking for a steering gear, and the boss directly recommended ZF. It's a German brand, a giant in the automotive components sector. They excel in transmission systems, like the longitudinal gearboxes used in BMWs, which can achieve shift speeds under 200 milliseconds. Actually, besides transmissions, their airbag sensors and active steering systems are quite common in high-end vehicles. Nowadays, their electric drive systems for new energy vehicles are also a new focus.

Once I drove a friend's Panamera, and its PDK dual-clutch transmission was actually manufactured by ZF. A typical German company headquartered in Friedrichshafen, even its logo features the classic black-and-white German style. Their product line is broader than you'd imagine, ranging from passenger car clutch plates to commercial vehicle axles. They've been making big moves in autonomous driving recently, with the proAI onboard computer released last year supporting L4 capability. NIO ET7's chassis control system was developed in collaboration with them.

During the last factory tour, I saw ZF differentials on the production line. The engineer mentioned this German brand excels at power distribution. They consistently rank among the top five global auto parts manufacturers, with 17 R&D centers alone. Interestingly, they once produced helicopter rotor systems and have now transitioned to making electric drive units. At the Munich Motor Show, I saw their steer-by-wire system—no mechanical connection between steering wheel and wheels, which felt incredibly futuristic.
