not just drag, but 22 are heavier than 20.

22 WLTP miles and not real miles so I would add a few more for good measure.If you go to the UK configurator and look at the technical data for a turbo on standard wheels then select 22” spider wheels the range reduces by 22 miles. So, that would be the minimum I guess.
you wrote“I had to recharge 3 times“. this is not enough information.I bought a macan turbo in early September and had a dash fault after two weeks that read Drive System Control Fault.
I was told by sales guy I bought the vehicle from it was a software update!
Two weeks later with this fault making an appearance two or three times, i was travelling from London to Scotland on a trip of 428 miles.
I had to charge the car 3 times.
The car has been at Porsche dealership now for a month and still the 100% charge shows only 244 miles.
I have done 1700 miles so far and Porsche have done over 300 miles while trying to empty and recharge / reset modules etc. What range is actually fact with these turbos as it’s nowhere near 300 on days Shen it’s 15degrees never mind 3 degrees.
the amount of energy my car is using is incredible.
Incidentally, another dealership told me my car had a catastrophic fault when I was there dealership for my third charge on my return journey.

I had to charge three times because there was no charge left after starting off at 100%. I got 156 miles with 4 miles left driving at average of 57 mph.you wrote“I had to recharge 3 times“. this is not enough information.
1.) do you use the charging planer?
2.) how is it set up. „minimal charge at destination“ and „minimal charge at charging stop“?
3.) the philosophy of this car is not to have maximum range from 0-100%. the philosophy is to drive as fast as possible from a-b. your consumption should not play that big a role in this. drive fast & charge fast, trust in the charging planer.
do not watch your consumption all the time.
But your average consumption is high(in the first post image) so even if you are not driving fast, you seem to drive aggressively or in cold weather I have on b roads typically 18kwh/100km and 25kwh/100km on the highway at 120km/h so yes if your average consumption is over 32kwh/100km aka 52 in miles your range is relative ok …I had to charge three times because there was no charge left after starting off at 100%. I got 156 miles with 4 miles left driving at average of 57 mph.
I then charged 100% and I managed to get 180 miles with 7 miles left.
the third charge was at Porsche Cambridge.
I certainly do not drive fast.

your consumption is high. but it is possible to have this with sport plus. but again it is not feasible to charge to 100 %. it takes to much time. set up your charging planner to 7% at destination. switch on the battery protection mode which limits the charging to 80% and uns the charging planner.I had to charge three times because there was no charge left after starting off at 100%.

I drive 99% of my time on dual carriageway or motorways. I do not have the car in any other mode other than standard normal.But your average consumption is high(in the first post image) so even if you are not driving fast, you seem to drive aggressively or in cold weather I have on b roads typically 18kwh/100km and 25kwh/100km on the highway at 120km/h so yes if your average consumption is over 32kwh/100km aka 52 in miles your range is relative ok …
20 inch wheels …
I think the shape and design was mislabelled as size (even though that’s also factually correct). ‘Spyders’ are less aero dynamic than the ‘S’ wheels because of the way the air travels over the wheels creating less turbulence as airflow cannot enter the wheel and arch etc.Not sure tyres/wheels make that much difference as rolling radius is similar whatever size isn’t it . Just more drag from wider tyres associated with bigger wheels.
I think you mean the opposite - Spyders are less aero dynamic and create more turbulence. I had them on my Taycan.I think the shape and design was mislabelled as size (even though that’s also factually correct). ‘Spyders’ are less aero dynamic than the ‘S’ wheels because of the way the air travels over the wheels creating less turbulence as airflow cannot enter the wheel and arch etc.
We've had our turbo since March and generally used it for longer trips, mostly motorway with some A+B roads. Summer we could achieve 3miles/kwh at 70 (ish) motorway speeds, now temps are dropping a bit can still get 2.7-2.8 miles/kwh. The car prefers the battery pack warm so if doing a long journey I'll charge to 100% and precondition the car on time to leave- it all helps use less energy on the move. Good luck, sounds like something is a bit amiss with your car. We have 21" aero wheels btw.I had to charge three times because there was no charge left after starting off at 100%.

Indeed… was poorly worded on my partI think you mean the opposite - Spyders are less aero dynamic and create more turbulence. I had them on my Taycan.
I’ve had my Turbo for a year and these are my sort of averages too.100% charge, driving 55 mph (90 kmph) in reasonable temperature, on 20 inch wheels, I can probably do >320 imperial miles in the Turbo. (I haven't done this at the full length, but this is what the math says.)
Cold weather, 75+ mph, hilly terrain, not wanting to stay at 100% charge ... 250 miles, maybe.
