Rivian and Volkswagen Group launched on

Tuesday the joint venture they had announced in June, valued at

$5.8 billion, to share software and electric vehicle

The joint venture aims to integrate advanced electrical

infrastructure and Rivian's software technology for future

segments, including subcompact cars, the firms said.

Volkswagen Group plans to invest up to $5.8 billion in

Rivian and the joint venture by 2027, they said, adding that an

initial investment of $1 billion in the form of a convertible

note has already been made.
