JapanApplied Intuition, a US software company, announced on 6 October 2026 that it is working with both Honda and Nissan on their next-generation software-defined vehicles. These are two separate agreements, each published as its own press release the same day, and neither is the shared-ECU programme the two Japanese makers signed with each other in August.
Honda: help with an in-house platform
Honda’s release says Applied Intuition will use its Vehicle OS software to speed up Honda’s in-house development of a centralised, upgradable SDV platform. Teams from Honda and Applied in Japan and Silicon Valley will work on what the release calls a full-vehicle platform for Honda’s next-generation vehicle architecture. Applied says its work covers all powertrains, hybrids included.
Honda’s own quote draws the boundary: the partnership accelerates internal development “while maintaining control over our vehicle architecture and software direction”, according to Mahito Shikama, Honda’s chief officer for corporate strategy operations. Honda is the customer and keeps the platform.
Nissan: AI tooling on top of a 2020 relationship
Nissan’s release leads with development tools rather than a platform. Applied is deploying AI-powered software-development tools to support what Nissan calls AI-defined vehicles, and will use Vehicle OS to support Nissan’s “scalable and open” next-generation in-vehicle software platform. Its teams in Japan and Silicon Valley will work alongside Nissan’s engineers in Japan.
The two companies have worked together since 2020, when Nissan adopted Applied’s simulation technology. The new agreement extends that into in-vehicle operating systems and AI-native software development.
How this differs from the Honda-Nissan ECU deal
On 31 August the two carmakers agreed to standardise their ECUs and core software with each other, for cars from fiscal 2029. The Applied Intuition announcements are supplier deals, one per company, and neither release mentions that programme or says how the two fit together. Neither gives a contract value, a delivery date or a model that will carry the software.
The releases do share a goal: shorter software development time, with Honda’s also naming lower cost. Applied also says it now works with carmakers in all major global regions, with existing partnerships in Europe and the United States.
