Hidden door handles are widely used in modern cars in China, with around 60% of the top 100 best-selling new energy vehicles, including EVs and hybrids, having them.

The minimalist design gives vehicles a “sleek look and reduces wind drag” but can be confusing to use, car industry analyst Stephen Dyer from consultancy AlixPartners told the BBC.

“Even I often find it difficult to locate the switch to open the door from the inside of an unfamiliar vehicle,” said Dyer, who is based in Shanghai.

But beyond their usability, the handles have been blamed for endangering the lives of drivers and passengers.

Electronically powered door handles became an industry trend, but raised “real safety concerns” when doors failed to open promptly, delaying rescue efforts after accidents, said Nanyang Technological University associate professor Lyu Chen.

“A door handle may seem simple, but it becomes safety-critical in the seconds after a crash,” Chen said.

Chinese carmaker Xiaomi faced intense scrutiny following two fatal crashes in 2025 involving its SU7 model, when suspected electrical failures allegedly trapped occupants.

One of the incidents took place on a highway in Tongling city, eastern China, killing three people, according to regional news coverage cited by state-controlled media Global Times.

Relatives of the victims said the passengers were stuck in the car as the vehicle’s doors could not be unlocked after the collision, the outlet said.
