As an indispensable part of new energy vehicles, hybrid electric vehicles bear the important significance of new energy in the current transformation stage. Because it is a transitional stage, it also bears the cost of various experiments. Roewe is undoubtedly a famous brand among many domestic new energy vehicles. However, the hybrid gearbox on the Roewe hybrid car is also famous, but this is a bit embarrassing. For example, the failure rate of hybrid gearboxes of Roewe e550, e950, ei6 and other models with rapid sales volume is often criticized by many car owners, and problems such as abnormal sound, oil leakage, misfire, non-start, and failure prompted by hybrid system often plague car owners.

Although there are advantages in cost performance, some other technologies are still in the experimental stage, so Roewe hybrid gearbox has rich fault performance. Roewe hybrid gearbox has a simple structure. AT present, the most widely used hybrid gearbox is the two-speed stepless gearbox, followed by the 10-speed AT hybrid gearbox loaded in recent two years. No matter the former or the latter, many problems have not been solved.
