For extreme hypermiling, perhaps. But in summer weather I routinely get over 130 mi range driving on freeways. I use cruise control and have the lightest wheels, so those could be factors.
Dealer just informed me that no more 2022 Mini Cooper SE are being produced

I also use cruise control on motorways etc. I don’t know where my wheels rank in the weight stakes of Mini wheels, but tbh I have to admit that my wheel choice simply came down to the set I most liked the look of. I do have OEM mud flaps on the car which could cause a wee bit more drag but I doubt it accounts for a 30 mile deficit. As I drive it more and as the weather changes for the better I expect it to improve.

I have no idea for Power/Corona spoke. The other alternative is to go on a diet plan and reduce driver weight.

The Pedal Spoke wheels appear to be an all-black version of the 525 "60 Years Spoke" wheels which are: 10.8 kg / 23.81 lb

Thanks. I'm getting the heaviest wheel. This will kill my stoplight races. But my bench racing will be unaffected.

Funny, I didn't even consider the weight when choosing my wheels. I chose the ones that I thought looked best. I feel that my stoplight races are purely dictated by what I'm driving. If driving the wife's Hi-Hy I give zero F's. If I'm driving my car I will happily smoke the ***** to my right gunning his engine to try to race to pull in front of me. Wonder how I'll act once I have my SE... Actually considering keeping my current Vert just for fun, but eventually the used car prices will peak. I won't miss gas and their prices, I can at least say that!
About the Power Spoke rims, Motoring File wrote, "The design of the wheels not only allows for the best aero of any MINI wheel it also is the lightest 17” offered."
Here's a list of MINI Cooper rim weights (not including the Power Spokes, unfortunately).

Thanks for those lists @teslarati97 and @insightman. Looks like my roulette wheels are the heaviest available in the UK for the SE, but like I say, I chose them because I liked how they looked. That means that my wheels add a total of 4kg over the lightest 17” wheels to a car which weighs over 1400kg. I can’t see how that would have a massive impact on range. The weight of the wheels is unsprung and more unsprung weight will impact on the handling, but again, I don’t think the effect on a vehicle like the SE would be significant.

Bwahahahahah, you picked the wheel. Bwahahahah. I too didn't consider the weight when choosing the wheels. In fact, the only thing I considered was what wheel my wife liked best.

There are three wheel-related things that affect EV efficiency: weight, drag, and rolling resistance.
For weight, 4kg might not seem like a lot, but I'm certain it is significant. I haven't done integral math in a long time, but my recollection is small difference over time can have a big effect.
Drag is another big factor and the closed design of the Power Spokes is going to create a lot less drag than the open designs. That's something that is going to be really felt at higher speeds. Look at the effect the air curtain slits have, increasing the SE's official range by 4 miles (3.6%, going from 110 to 114).
Finally, rolling resistance is determined by the tires. I don't know if that's the biggest factor, but it's extremely significant on EVs since it's a measurement of how hard the car has to push to move forward.
Many years ago I bought the first titanium bike frame made in the US, the Teledyne Titan. I transferred the wheels from my fancy Schwinn Paramount to my Titan and was amazed how quickly the lighter bike could accelerate. Then I spent the money to get much lighter rims and silk tires (I don't believe silk tires are a thing anymore, but what a beautiful high-pitched hum they made!). I was astounded at how much easier the light bike accelerated with the lighter rotating weight. I could have just said this, but I like telling long stories: A lighter wheel requires less energy when accelerating a vehicle.

That sounds like quite a machine you had!
I know that swapping out cast alloy wheels for forged or carbon fibre wheels make a big difference to the handling of motorbikes. Reduced weight in the wheel reduces gyroscopic effect which reduces the level of effort required to change direction, but it also has the benefit of being easier to accelerate as you say. My bike weighs just over 200kg fuelled up. A small reduction in the weight of the wheel has a bigger impact as the overall weight of the vehicle is low, so the reduction in weight is a bigger proportion of the overall vehicle weight.
i admit that any such mod to a bike is done purely for performance; not for efficiency.

I agree with almost everything you’ve said, but I just don’t see how 4kg would make a *significant* difference to the efficiency of a 1400kg car. Rolling resistance of the tyre, tyre pressure, tyre weight, drag (from both the wheel design and the rest of the car) are all key as you say. It would be interesting to see which set of wheels was the most aerodynamically efficient after the power spokes, just out of interest.
All I wanted to say in my last post was that when it came to the wheels, I went with the set I liked best. Wheel weight or the assumed efficiency of the wheel design didn’t enter my thoughts. Those elements themselves would not account for a 30 mile drop in range from a single charge.

Everyone should definitely get the wheels they like the most!
I recently saw a news story on ice racing, and they strip everything out of the cars for performance. The racing seems great to me, and it seems like a safe place to practice the Scandinavian Flick in the SE.
Just got off the phone for my 23 order and while the price is the same, they did eliminate most of the options for the Signature trim. The oddest is that you can only get body matching roof color. Not able to get a white or black roof.

Is roof color locked to Signature trim? Do you know if you can still get black / white on Sig+ or Iconic?
Pretty sure it is available on the higher trims. Note that it isn't an option on the lowest trim of the ICE Coopers ("classic" trim)
So for the 2023 Sig trim your only choice is one of 4 colors, one of two wheels and a single option to add roof rails. Besides the roof/mirror caps, they also removed choice to not black out everything and options for HUD, cruise control and alarm systems.
