Rivian leapt as Volkswagen will now up to $5.8 billion in their joint venture. VW aims to produce the first resulting vehicles in 2027.

Volkswagen AG raised investment plans in Rivian Automotive Inc. by $800 million, signaling its commitment to the US partner even as electric-vehicle demand softens and the incoming Trump administration threatens to curtail supportive policies.

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.
