18in vs 20in Wheel

I'm not a fan of the SEL/LE wheels. My take is that the fractal look takes away from the smooth lines of the car. I wanted something more simple like a five spoke. After researching a bit, my local tire dealer thought that these would work well.

However, though they look pretty cool, they might be inefficient compared to the FAST EV ones shown above. I've definitely noticed that all of the new EV wheels are more "closed" on the face than traditional wheels (makes aerodynamic sense). Has anyone found any other options?

These are cool, but the branding is a little brash and they are discontinued.

Alright then, I made the switch to the 18" wheels on the SEL. These are Niche Milans.

1) I like that the wheels are more minimal and allows the airfoil design aspect of the car to shine through.
2) I'll benefit from the 18" wheels that are less heavy and have less width wrt aerodynamics that provide for better performance.
3) The tires/wheel look is not as svelte, but it gives the car a retro/future aesthetic.
4) The larger tires will keep the wheel's from getting curb rash/rubbing when parking.

Here is a 1973 Porsche 911, which is the look I was kind of after.

I'll have to follow up to see what % range increase I see.

looks like your new wheels have HUGE air gaps between the spokes. If that is the case, you won't be getting much/any improvement in range. The Factory 18" wheels are almost totally enclosed, there is little/no gap, just black paint, which accounts for the extra efficiency.

You missed some of the comments at the start of this tread. The wheels have less width so are more aerodynamic that way. Plus, I'm seeing better mileage because the wheels are less heavy and need less power to get up to speed. I'm seeing a 10%-12% increase in the KW/mi over the base SEL wheels.
