Hyundai IONIQ 7 concept 'pure shape' K-form
 

If the link works, you'll have a look at the first 'kamm-back' since the 1987 Renault VESTA-II concept, Cd 0.186.
Hyundai isn't providing a Cd yet, but the car is using virtually it's entire roofline for pressure recovery.
Welcome to 1935!

I watched the video and felt absolutely nothing. Advertisements aren't meant for folks like me that just want basic facts answered if you're going to take up my time.

In the lengthy "description", no mention is made about why it's called "Seven", or if it has enough room for 7 passengers, which would be my interest.

The problem with the EV industry is all the marketing folks think the typical person is buying a thing to save "the environment". Hardly anyone is motivated by that. Just make a good car, and people will want it. Drop all the nonsense about how you're going to save the world by purchasing a huge, power-hungry, expensive thing, and just show why it's a better car than others.

There's 3 people that care if the seats decompose easily or not. Make them comfortable and durable- that's what people want.
