WABCO Holdings, a Tier 1 supplier to the commercial-vehicle industry, is supplying its new modular automated manual transmission (AMT) system to China National Heavy Truck Corp. (CNHTC). CNHTC is the largest producer of heavy-duty trucks in China and the first OEM to adopt WABCO's AMT system in volume production. The advanced transmission system will be used on CNHTC’s new HOWO Heavy Truck series. By optimizing the gear shifting process, the AMT system is said to improve vehicle control and carbon footprint while enhancing comfort. WABCO will produce the system at its China facility in Shangdong province.
