Nikkei xTECH reports on E2E autonomous-driving unicorn Nissan relies on and teardown of a Chinese EV

On October 20, 2026, Nikkei xTECH reported on an E2E autonomous-driving unicorn Nissan relies on and the CTC battery structure revealed by a teardown of a Chinese EV. The article discussed issues involving Tesla and BYD and described their respective positions.

The report covered Nissan, Tesla and BYD together, showing that competition in autonomous driving and EV design is expanding beyond the vehicle itself to include areas such as vehicle-body integration and data use. For automakers, the choice between in-house development and adopting external technology could affect both product design and manufacturing methods.

Nikkei xTECH's article is notable for addressing Nissan's autonomous driving and the vehicle-body and battery structure of Chinese EVs within the same context. However, the focus here is the report itself, and the original source must be consulted for details of the technologies and assessments. This article therefore focuses on how to interpret the competitive landscape based on publicly available information. Among related previous reports, [Toyota races to catch up with Tesla and Chinese automakers in autonomous driving, while also stepping up efforts in robots and flying cars, Nikkei xTECH reports](/en/news/toyota-chases-tesla-and-chinese-rivals-in-autonomous-driving-nikkei-xt-716397) is one example. The article, published October 18, 2026, described Toyota as pursuing Tesla and Chinese automakers in autonomous driving, with robots and flying cars also positioned as part of that broader effort. The current report on Nissan again raises the question of how automakers can incorporate external E2E players rather than relying solely on in-house development for the core of autonomous driving. While Tesla has been cited as a leading example of E2E, Chinese automakers have made implementation capabilities, including vehicle design and battery integration, part of their competitiveness. Nissan's choice therefore appears to mean more than simply adopting software; it could amount to redesigning the vehicle architecture as a whole. Next, BYD publishes humanoid robot exterior design patent; applications include service, education and industrial settings and Nikkei xTECH reports on BYD's aims for external sales of a new battery pack for its Racco compact EV reinforce the view of BYD not just as an automaker but as a design player encompassing component integration and peripheral equipment. The former reported the disclosure of a humanoid robot's design, while the latter conveyed reports that BYD may sell a new battery pack for its compact EV to outside customers. Both can be read as efforts to extend implementation beyond the vehicle itself. The fact that the current report discussed a Chinese EV teardown and CTC structure together may reflect how this kind of integrated design affects not only vehicle performance but also manufacturing processes and serviceability. However, the details of the CTC structure and the identity of the E2E company Nissan relies on should be confirmed in the original source. For the industry's structure, an important point is that competition now links not only vehicle sales volumes but also data collection, E2E training, vehicle-body integration and battery-placement design. The simultaneous mention of Toyota, Nissan, Tesla and BYD makes clear that autonomous driving and EV structure are not separate fields but extensions of the same design approach. Points to watch include: 1) the identity and role of the E2E autonomous-driving unicorn Nissan relies on; 2) which aspects of the CTC structure shown in the Chinese EV teardown differ from BYD's; and 3) how these factors affect mass production, safety and maintenance costs.

For Japanese automakers, the issue is likely not only whether to adopt E2E autonomous driving, but also whether they can reorganize vehicle design around battery-integration structures such as CTC. How they redesign component counts and manufacturing processes also affects Japan's division of labor in vehicle-body design, battery packs and control software.
