Powered by a BMW engine and normal fuel, the AirCar flew for 35 minutes between two Slovakian airports in 2021, using runways for take-off and landing.
It took just over two minutes to transform from a car into an aircraft.
Now vehicles made based on its design will be used within a “specific geographical region” of China.
Hebei Jianxin Flying Car Technology Company, headquartered in Cangzhou, has purchased exclusive rights to manufacture and use AirCar aircraft inside an undisclosed area.
The firm has built its own airport and flight school after a previous acquisition from another Slovak aircraft manufacturer, said Anton Zajac, cofounder of KleinVision, the company which created AirCar.
Having led the way in the development of the EV revolution, China is now actively developing flying transport solutions.
Last month a firm called Autoflight carried out a test flight of a passenger-carrying drone between the cities of Shenzhen and Zhuhai. The journey, which takes three hours by car, was completed in 20 minutes, it said – although the aircraft contained no passengers.
And in 2023 the Chinese firm eHang was awarded a safety certificate by Chinese officials for its electric flying taxi. Here, the UK government has said flying taxis could become a regular feature of the skies by 2028.
But unlike these drone-like passenger aircrafts, AirCar does not take off and land vertically, and requires a runway.
KleinVision declined to say how much it had sold the technology for. AirCar was issued with a certificate of airworthiness by the Slovak Transport Authority in 2022 and featured in a video published by YouTuber Mr Beast earlier this year.
There are still considerable hurdles for this form of transport in terms of infrastructure, regulation and public acceptance of the technology.
“This brave new world of personal transport is acting as a great leveller,” said aviation consultant Steve Wright.
Global attempts to regulate the sector left “everyone scrambling to come up with a whole new set of questions that need to be asked”.
“In this respect the West’s history can sometimes slow things down, as there is a bit of a temptation to try and squeeze these new machines into the old categories,” Mr Wright added. “China could well see this as an opportunity to get ahead.”
Similar concerns once applied to electric cars – in which China which has become a global market leader.
The sale of the Slovakian AirCar could raise questions about whether China might be poised to do the same with flying cars.
Mr Wright said while prototypes like the AirCar were “great fun”, the reality was likely to end up being more mundane “with queues and baggage checks and whatnot”.
