Volkswagen Group (VW) and Tesla rival Rivian have launched a joint venture, with the German car giant increasing its investment in the partnership. The two companies say the the deal is now worth $5.8bn (£4.55bn) - up from an initial pledge of $5bn by VW.

The joint venture aims to integrate advanced electrical infrastructure and Rivian's software technology for future electric vehicles of both companies, across all relevant vehicle segments, including subcompact cars,

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.
