I have the limited and I am averaging in the high 50's right now with the temps also in the high 50's in a mix of highway and urban driving in the hills of Arkansas. Some claim that with small wheels/tires you have gives increased mpg -- slightly! Not sure how much the crappy looking wheel covers increase mpg. May just be an advertising ploy!

 

well they '' look'' more aerodynamic than the other models. i know the eco aero hubcaps on the tesla model 3s have been proving to increase range/''fuel'' economy

 

The aero hubcaps offer no difference in fuel savings. They're supposed to act as fairing to help channel the air but it's more of a gimmick. My mileage has not changed whatsoever from the open alloys vs. factory wheel covers. I was told it's designed to look the part and that's it. Tire pressure, tire width, rolling resistance, air temperature, driving style have a lot more influence on your mileage. Similarly, you get the same range on a Tesla Model 3 with the optional 19" sport wheels/tire vs. 18" Aero wheels in real world driving.

 

Yeah the wheel covers suck, that was the first change I made. The wheels are actually not bad underneath... I discovered that mine are black and liked it way better. I may get a less gas mileage but who cares Ioniq get 5 times better MPG than my 4x4 lol

 

The wheels are the one thing I think looks terrible on these cars. Minimally they should be all metal. I've been unable to find photos of what the wheels look like with the plastic silver doodads removed. Have any to share?

 

A photo is easy to find just google Hyundai ioniq wheel, they are black. Here’s a link:

Found this one which shows the car without the wheel covers and describes efficiency. Covers are going to stay on my vehicle.

Wheel covers and their impact on efficiency

TLDR: Testing of wheel covers at 110km/h show a increase in efficiency by a little more than 7% in clear winter conditions (-12°c low windspeed and dry roads). After stumbling over a mod for the Nissan Leaf, where some users have been fitting “leaf-petals” into the holes in the rims I looked...
