While the lights are off, hundreds of robots labor through the night to construct electric vehicles in a factory in Ningbo, which is located just south of Shanghai. A few engineers in robot maintenance, a quality control team, and the steady mechanical rhythm of arms welding, assembling, and moving parts with a consistency no human workforce could match make human presence almost entirely optional.
Approximately 300,000 cars are produced annually at the facility. It has about 1,600 employees. Finished cars wait in long lines outside its walls in parking lots and shipping yards, ready to be transported to markets that were off-limits to them two years ago, such as Europe or Canada. The company’s manufacturing data, production algorithms, process enhancements, and the engineering knowledge gained from years of iteration are all kept within its walls. In a very direct sense, everyone else in the global EV industry most desires access to that knowledge.

The most significant industrial rivalry of this decade is that between BYD and Tesla. This rivalry has the unique characteristics of rivalries that function at scale: it is at once a commercial struggle, a geopolitical conflict, and, increasingly, a contest over information.
Both businesses are acutely aware of each other’s knowledge. Both have seen the effects of that awareness in hiring practices, legal disputes, and government decisions regarding the vehicles that members of the armed forces and intelligence community are allowed to drive. The EV race does not have a corporate espionage component. It is recorded, contested in court, identified by intelligence services across several nations, and subtly influences decisions made concurrently in defense ministries and boardrooms.
The simplicity of the reasoning behind China’s decision to prohibit military personnel and civilians employed in sensitive government facilities from driving Teslas to work made it noteworthy. Large volumes of data are gathered by Tesla vehicles and sent to servers, including location, driving patterns, and camera footage from the car’s external sensors.
Beijing considered it an intolerable risk to have that data collection apparatus operating near military installations and secure facilities. The ruling was not presented in a dramatic way as a way to prevent espionage. It was presented as standard security precautions. However, the implication was obvious: a foreign company’s connected car operating close to sensitive infrastructure could serve as a platform for collection.
This reasoning is not limited to Teslas in China. It is equally applicable to Geely-owned Volvos in European NATO member states, BYD vehicles in Canada, and any networked automobile manufactured by a business whose data governance is governed by a different set of laws.
In late 2025, Israel’s military reached a similar conclusion regarding Chinese EVs, starting to phase out senior officers’ leases of these vehicles. Concerns regarding the data collection capabilities of contemporary connected cars—such as cameras, microphones, GPS tracking, and the numerous sensors that enable sophisticated driver assistance systems—led to the decision. These systems are not exclusive to Chinese automobiles.
China banned Tesla vehicles because they had all of them. The distinction is jurisdiction: under Beijing’s national security laws, which mandate that businesses comply with intelligence requests, the Chinese government may have access to data gathered by Chinese-made vehicles. Under comparable U.S. legal frameworks, American intelligence may have access to data gathered by vehicles manufactured in the United States. Both sets of worries are valid. Depending on which nation is raising them, both are frequently discussed selectively.
Alongside the data security narrative, there is a deeper industrial espionage story that is somewhat more directly relevant to the companies themselves. This story includes trade secret theft, engineers moving between companies, and legal disputes over battery chemistry and manufacturing processes.
One of the most impressive industrial ascents of the last thirty years is BYD’s transformation from a battery manufacturer founded in 1995 to the largest EV manufacturer in the world. This growth was largely due to both significant government support and true engineering innovation.
Similar patterns of innovation combined with strategic advantages—regulatory credits, early mover positioning, and a manufacturing approach that the rest of the industry spent years trying to understand and replicate—were followed by Tesla’s own ascent from a startup rejected by the established auto industry to the company that redefined what an electric car could be. Both businesses have devoted years to safeguarding their creations. In one way or another, both have been accused of profiting from information they shouldn’t have.
All of this is made more tense by the price war that is currently tearing through China’s domestic EV market. In May 2025, BYD initiated a vigorous round of price reductions, bringing affordable cars below the $21,000 mark and lowering some models’ prices by ten to thirty percent. The chairman of Great Wall Motors publicly warned of an Evergrande-style debt crisis developing in the auto industry, claiming that some manufacturers were “addicted to burning money for market share.”
This action unnerved rivals and alarmed some industry observers. In the weeks after the announcement, BYD’s own stock price dropped more than 15% from its highest point. Every regulatory decision, tariff negotiation, and security concern about Chinese vehicles operating in Western markets has a higher stakes because of the pressure created by that kind of domestic price competition, which makes the international market more important rather than less. This means that the push into Europe and Canada is not just commercial ambition but also financial necessity.
When discussing EVs in 2026, it’s difficult to ignore how the frames of espionage, trade policy, and competitive industry all blend together. Following a trade agreement, Canada decided to permit 49,000 Chinese electric vehicles into its market. However, the government has yet to fully address security concerns regarding data storage, the conditions under which Chinese companies might have to share that data with Beijing, and the potential infrastructure that a sizable fleet of networked Chinese vehicles might eventually represent.
These are not suspicious inquiries. China posed the same queries regarding Tesla and responded by limiting the parking spaces. Similar calculations are being made by Western governments more slowly and under much greater political pressure from both domestic automakers seeking protection and consumers who genuinely want access to reasonably priced, well-made electric vehicles regardless of where they are made.
Observing all of this, it seems that the EV industry has evolved into something that neither its early investors nor its founders fully expected: a venue for national competition that also happens to manufacture automobiles. In Ningbo, the robots continue to construct. The attorneys in Palo Alto and Shenzhen continue to file. The intelligence services in Brussels, Tel Aviv, and Ottawa remain vigilant. And in every nation where they are permitted to drive, the cars themselves continue to gather data, mile by mile.
