Huawei EMB debuts in GAC Aion Ray7, entering the Bosch-dominated brake-by-wire market with a 158,800 yuan top trim
Huawei DriveONE EMB full-wire brake-by-wire mass-production debut lands in the GAC Aion Ray7, not in HarmonyOS Smart Mobility or Qiankun models, with a top trim at 158,800 yuan and the model line starting at 128,800 yuan. Huawei says EMB eliminates hydraulics and uses independent four-wheel electronic control, with a 78-millisecond response; Bosch's brake-by-wire share in China has fallen from over 90% in 2021 to about 53.7% in the first half of 2024. EMB unit price is about 2,500 yuan, higher than EHB's about 1,700 yuan, with the affordability point expected around 2028; the Ray7's 33-meter stopping distance is a launch-event figure, and mass-production consistency remains to be verified.
