Last June, VW said it would invest $5 billion in Rivian as part of a new joint venture that’s focused on developing a new electrical architecture and vehicle software for future models, including subcompact cars, with the first planned for 2027. The investment size has now increased to $5.8 billion.

The companies said the deal is now up to $5.8 billion – up from up to $5 billion – with the first VW models to use Rivian's software and electrical architecture arriving as early as 2027.

The venture will be jointly run by Rivian's Chief Software Officer, Wassym Bensaid, and Carsten Helbing, Volkswagen Group's CTO. They'll serve as co-CEOs. It'll be based in Palo Alto, California, to start. Three more sites are in development North America and Europe, the companies said on Tuesday.
