The cabin includes configurable seating, a multifunctional mobile floor console, a large display and centralized electronics that allow rapid switching between driving, lounge, family, rest and cargo scenarios. The platform is designed as a production-ready smart-cabin architecture rather than a static concept.

Toyota Boshoku is developing similar coordinated interior concepts. Its LOUNZE+ system links seats, door trims and the console so interior components can operate together according to the selected scene, while the earlier Future Creation Modular Seat used interchangeable structural configurations to support advanced, relaxed and sporty seating modes.

Market Trends

• Modular Interiors Are Shifting from Individual Components to Shared Cabin Architectures

Interior suppliers are increasingly designing common hardware foundations that can support multiple cabin layouts and use cases. Magna's Flexible Seating System uses long-travel rails, rotating bases and support structures as reusable building blocks that can be configured differently across vehicle programs.

This approach allows automakers to reduce the number of unique components while still offering differentiated cabin experiences across trims, body styles and regional vehicle programs.

• Plug-and-Play Consoles Are Creating Upgradeable Cabin Features

Center consoles are becoming a major modular-interior platform because they can combine storage, charging, displays, work surfaces, beverage functions and climate-related features in a compact location. FORVIA's On-demand center console allows modules to be changed without redesigning the main console structure.

Upgradeable console systems can support post-sale personalization and reduce the need to replace complete interior assemblies when functions change over the vehicle life cycle.

• Electric Vehicles Are Increasing Spatial Modularity

Battery-electric platforms create flatter floors and reduce some drivetrain intrusions, allowing longer seat rails, movable consoles and more dramatic changes in interior layout. This makes modular interior architecture especially attractive for electric SUVs, MPVs and premium vehicles.

The combination of flat-floor packaging and centralized electronics also simplifies coordination between movable hardware and software-controlled cabin modes.

• Smart Surfaces Are Becoming Modular Functional Layers

Interior trim is increasingly being used as a functional interface rather than a fixed decorative surface. Antolin is integrating HMI, smart glazing, E-Ink and touch-responsive surfaces into door and cockpit systems, while Yanfeng and FORVIA combine sensing, lighting and display functions with interior components.

This trend allows OEMs to vary digital and interactive content on common physical structures, increasing modularity at the software and functional-surface level.

• Circularity Is Increasing the Appeal of Replaceable Modules

Modular interiors can support repair, refurbishment and component upgrades without replacing complete assemblies. FORVIA positions its modular console around reuse and lifecycle extension, while suppliers are also increasing recyclable and lower-carbon materials in seat, console and trim structures.

The ability to separate functional modules from longer-life structural components can support lower material consumption and improve end-of-life recovery.
