As of September 2nd， the “high-speed power loss” incident involving the Vanke S800 has recently become a trending topic. Some owners have managed to replicate the scenario， drawing criticism from netizens.
The situation unfolded when a blogger reported that their newly delivered Vanke S800 experienced a sudden loss of power while driving at high speeds. The dashboard displayed 0% battery while the fuel tank was full (with a range of 773 kilometers)， and the system repeatedly issued warnings such as “Please take over immediately” and “ESP not ready.” The owner asserted that they had switched to fuel-priority mode when the battery reached 30%， but the battery was still abnormally depleted， and they denied any operational error， stating they were willing to assume legal responsibility.
Subsequently， the Harmony Intelligent Driving Changchun User Center responded， explaining that the vehicle’s continuous operation after the fuel ran out triggered the range extender’s protection mechanism， which limited power output to preserve range. They stated that refueling would resolve the issue， denying it was a product quality problem. Other Harmony Intelligent Driving stores and tech bloggers also pointed out that this is a common protective logic for range-extended electric vehicles (REEVs).
In response to the controversy， some owners have successfully replicated the exact scenario. In essence， this involves running both the battery and fuel to empty， then refueling， and within ten minutes of aggressively accelerating before the battery has recharged， the system restricts power output and prompts for takeover.
Some netizens have aptly compared this to a mobile phone running out of battery and shutting down. Even after plugging it in to charge， it cannot immediately turn on; it requires some time to charge before it can be powered up.
Some related bloggers， after witnessing this， directly stated that this is quite boring and amounts to a deliberate smear of Huawei. Prominent figure Chen Zhen also commented， “I’ve seen the situation. Normally， it is almost impossible for a range-extended vehicle to deplete its battery to 0%， especially when the fuel tank is full.”
The widely circulated jokes about this incident are for everyone to experience.
