DETROIT — Volkswagen Group increased its planned investment for a joint venture with electric vehicle startup Rivian Automotive to $5.8 billion as the companies have broader aspirations than they initially announced for the team-up. Investors were impressed with the details of the deal, sending shares of Rivian up 13% in trading Wednesday. The companies said they expect roughly 1,000 people to work for the joint venture. But VW's capital to Rivian isn't guaranteed, and neither is the success of the deal. The automotive industry has seen a number of major mergers and joint ventures that don't result in long-term successes.
