On the road to software-defined vehicles
VW and Rivian validate new E/E architecture in winter tests
The tests were carried out under the extreme conditions of the northern Swedish winter.

Volkswagen and Rivian have successfully completed winter testing of their joint E/E architecture. The upcoming ID. Every1 will be the first model to deploy it — marking a key step in VW’s EV strategy.
Volkswagen is accelerating its transition
towards software-defined vehicles. Together with Rivian, the company has
now completed a key milestone: winter testing of its next-generation electronic
architecture under extreme conditions in northern Sweden.
The tests, conducted in Arjeplog near the Arctic Circle,
exposed multiple prototype vehicles from Volkswagen, Audi and Scout to low
temperatures and demanding driving scenarios. The results, according to
Volkswagen, confirm that the new architecture performs reliably under harsh
environmental conditions.
Why the ID. Every1 marks a turning point
The upcoming Volkswagen ID. Every1 will be the first
production vehicle to feature the new E/E architecture
developed within the joint venture with Rivian. The model is expected to
launch in 2027 at a target price of around €20,000.
More importantly, it serves as a blueprint for a broader
rollout. Volkswagen plans to deploy the architecture across multiple brands,
including Audi, Scout and later Porsche, before extending it group-wide.
The technology will initially be used exclusively in
electric vehicles. For Volkswagen, this marks a strategic shift towards a
unified, software-centric platform designed to support future digital services
and scalable vehicle architectures.
The joint venture, founded in November 2024, focuses on
developing this architecture for Western markets. In parallel, Volkswagen is
pursuing a separate approach in China through its partnership with Xpeng.
How zonal architecture reduces complexity
A key feature of the new system is its zonal architecture.
Instead of distributing functions across numerous individual control units,
computing power is consolidated into a smaller number of central and zonal
controllers.
In practical terms, this means that a single controller can
manage multiple functions within a defined area of the vehicle. For example,
systems on the driver’s side — such as throttle input or window controls — can
be handled by one unit rather than several independent ECUs.
VW–Rivian E/E architecture: key facts at a glance
- Partners: Volkswagen and Rivian (joint venture “RV Tech”)
- Focus: Next-generation E/E architecture for EVs
- Test: Winter validation in Arjeplog, Sweden
- First model: Volkswagen ID. Every1 (planned for 2027)
- Target price: ~€20,000
- Architecture: Zonal computing instead of distributed ECUs
- Benefit: Reduced complexity, shorter wiring, lower costs
- Rollout: Across VW Group brands (Audi, Scout, Porsche, others)
- Investment: Up to $5.8 billion by Volkswagen
- Strategic goal: Foundation for software-defined vehicles
This approach reduces the number of control units, shortens
wiring harnesses and lowers system complexity. As a result, it also contributes
to cost reduction and improved scalability.
Zonal architectures are already
being adopted by companies such as Tesla and several Chinese
manufacturers. Volkswagen’s collaboration with Rivian aims to bring this
concept into its own vehicle portfolio, while ensuring compatibility with
existing components and development processes.
With the successful completion of winter testing, the
project remains on schedule. The milestone is also linked to staged financial
commitments, with Volkswagen investing up to $5.8 billion in the partnership.
The broader implication is clear. As the industry moves
towards software-defined vehicles, E/E architecture is
becoming a defining factor — not only for performance, but for cost,
scalability and long-term competitiveness.
