Could be very big for extreme EV supercars that can redefine the image of electric cars. If they are the sleekest and fastest cars, then there's no reason not to buy one https://www.motor1.com/news/249674/porsche-takes-stake-rimac-electric/ I can see why Porsche wants a piece of this!!
If you can't beat 'em - join 'em! The Rimac C2 is a tour de force - a masterpiece. I can't see how any hypercar can get any faster / quicker, in any but the tiniest way.
New Story on InsideEVs this morning Porsche increases its investment in Rimac as Hyndai walks away. "More specifically, Rimac officially entered into a 55-45 joint venture with Porsche. The goal is to take over Bugatti, which also lives under the Volkswagen Group umbrella." https://insideevs.com/news/583292/hyundai-ending-rimac-partnership-report/
