Tesla pushes next-gen Roadster demo to August on thruster delays

Tesla has slipped the public unveil of its long-promised next-generation Roadster to August or later, with The Information reporting on June 5 that the SpaceX-developed cold gas thruster system - internally code-named A71 - still needs more work after a late-April internal demo. The latest slip is at least the eighth Roadster delay since the 2017 prototype, dragged TSLA down 6.9% on Friday and put the stock on track for its worst week in a year amid broader demand and product-execution concerns.
