"Many countries might potentially host a large number of factories in Europe," He Xiaopeng told reporters in Munich.
"Of course, most are still in Germany."
Suffering from US tariffs, slimmer margins from electric cars and intense competition from China, Germany's carmakers have looked for ways to use up excess capacity in their plants in an effort to avoid costly and divisive closures.
Volkswagen CEO Oliver Blume -- who on Monday told staff that four German factories might need to close as it eyes mass job cuts -- in April floated the possibility of European VW plants making cars for the company's Chinese partners.
Volkswagen has a 4.99-percent stake in XPeng and in China works with the company to develop cars for the local market.
Localising production in Europe could help Chinese carmakers avoid European Union tariffs on their electric cars.
It could also help keep local politicians onside as fears grow of a so-called "China Shock 2.0" -- used to describe Chinese firms shift into more high-tech manufacturing, which is threatening many traditional European industries.
Brands including BYD, Geely and Chery took almost 11 percent of the European car market in May, according to automotive intelligence firm Dataforce, up from just under three percent years ago.
XPeng itself almost doubled its vehicle deliveries in Europe to 31,000 in the first half of the year while almost tripling its deliveries in Germany.
Discussions about potential new collaborations in Europe were at an early stage, He stressed.
He added that XPeng -- which currently has a deal with Austrian contract manufacturer Magna Steyr to make cars on the continent -- wanted "to invest in Europe".
"We're happy to work with many companies, including Volkswagen, jointly," He said.
"We hope that in the future there will be not just one, but even multiple different factories in Europe, plus different R&D opportunities -- some for cars, some for robots -- covering all kinds of work."
