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.
