Question about improving miles per kilowatt

Are either of them quiet at all?

Any recommendations for caps to cover the wheels? Been looking around but can't find anything for my car.

That's really smooth underneath! Not much you can do there. Pizza pans are often used as wheel covers!

But how do you attach them? Any transparent options so I can still see my rims?

Transparent covers would collect dirt and debris on the inside.

You could fabricate a disk that fit between the hub and wheel of either clear stuff or painted black metal. Inmho, people also need to show they benbow calipers.

Isn't as aero as on the outside but does stop air leakage through the rim.

So, in order to stretch the battery 10%, you've got to do what you're already doing with 90% of the energy.
A 10% reduction in Road Load.
All aero.
All R-R.
Or, some combination of the two.

The KIA EV6 GT-Line RWD is EPA COMB 310-miles range, compared to the IONIQ 5, at 256-miles.
The RWD has 235/55 R19 101H KUMHO Crugen HP71 EV ( M+S ), vs 255/45 R20 105V Michelin Primacy Tour A/S ( M+S ).
The narrower section has better aerodynamics, and I suspect a lower coefficient of power absorption.
Mercedes-Benz is using a 185mm section on their EQXX, range leading concept.

In 2018, Robert Palin, at electrek.com, reported that the 19-inch Tesla Model 3 Aero Wheels were good for a 10% efficiency gain, and 5% higher range on the highway.
Since Hyundai/KIA/ Genesis all share the same mechanicals under the skin, you might be able to find a direct fit wheel, or wheel cover option, which along with a LRR tire, nearly gets you to your 10% range target.
If not, a small amount of streamlining ought to get you into the inzone.

[Piotrsko]

Yeah, but he does like the looks of the present probably very expensive rims. Otherwise your comment about efficiency was spot on

[liquidshadowfox]

No doubt I love the rims but I still haven't seen anyone make aftermarket rim covers for my car yet still looking at the possibility of changing rims for smaller wheels (19" the smallest) but if I can keep using mu current 21" rims that would be preferable. I also looked around for those hancook ion tires but they aren't in stocks anywhere yet. They seem to offer low rolling resistance and better range for EVs so I wonder if they are any better than the current Michelin primacy tour tires I have on atm.

You're not going to save 10% on wheel treatments. There's no getting around the fact that you're going to have to slow down.

The good news is that saving 10% doesn't require going all that much slower. My guess would be something like 4 MPH slower. It's the "mod" that improves all drag producing parts of the vehicle.

Here's the various mods for consideration. None except the extreme ones are going to get you 10%.

Not too many years ago there was about a 132-page special report on rolling resistance published online.
All-season LRR radials had the lowest drag.
Followed by 'touring' tires which had more.
And bringing up the rear were the 'performance' tires with the highest drag.
In a just world, California would have been able to require full disclosure by tire makers of specific rolling force coefficients for each make sold in the state. It would have helped the entire world.
Having not passed into law we're left with the equivalent of buying a home of known square-footage, however no disclosure requirement of whether or not there's any insulation in the walls or attic.
Shame.
