Macan 2024 vs 2025 massive consumption difference?

[Petzi]

Actually it's 7% but this is irrelevant as the WLTP test average speed is 46 km/h and the OP is doing 300 km stints at 140-150 km/h motorway speeds which means his average speed will be over 100 km/h or over twice the speed of the test. Consumption is not linear so any calculations based off WLTP will be inaccurate.
There is no magic in the 2025 models, just smaller/different rims/tyres/pressures/spec/weather conditions/driving style/etc.
While tyre compound, pressure, size, wear, etc. make a difference, wind especially rain make the biggest difference, plus weight (more equipment - heavier). Of course as with all cars biggest difference will be your right foot.
I also drove a 4 loaner, same suspension/wheels as my 4S. It was over 20% more efficient, going off the WLTP figure the difference between the 2 models is negligible, which shows how a test run inside a lab using specific, completely unrealistic conditions has nothing to do with real world driving.
If you are interested in real tests head over to youtube and check the excel file of Bjorn Nyland, Macan 4 on 22s at 120 km/h, consumption 27 kWh/km, range 350 km (I have rounded the figures).
This then gives the ill-informed ICE crowd a chance to cry about EVS how crap they are when "advertised range" is 613 km and you get 280 km (80% charge of 350 km).
Try explaining to them that a lab test with 46 km/h average speed at 23 deg C has no relevance to daily driving.
For anyone interested in the results but can't bothered to check consumption at this speed for efficient cars like Tesla M3 RWD Highland on 18s is ~15.5 kWh/km, SUVs on 22s range from 26 to 32 kWh/km for Chinese behemoths (E-HS9).

this is not how wltp works. google helps

Yes, the difference is:
- loaner has roof railings and rear wiper (which is not an advantage)
- loaner has 20" wheels and Bridgestone tiers, mine has 21" Michelins
- loaner is a very fresh production 2025 MY, mine was delivered 09/2024
- other details like colour and options should not matter much
- drive settings are the same (suspension settings, regen etc)

I’d assume the 21’s make a difference.

Your assumption is correct. Larger wheels kill the range, my other EV is on 18s.

Speed wise it's a 30min test, average speed is 46km/h, as you can see from the graph speeds over 120km/h are not even 10% of the "trip" (<3min). It's not hard to see why the WLTP "range estimate" does not translate well to highway driving where most of the consumption for EVs is.

The notes in the update seem to indicate there was some adaptation in the Battery management system, to better represent the true capacity of the battery …

This is easy to check, I assume I can read all the module versions like I can on the VW and compare the versions before & after the update. Some people after update on the VWs start claiming increased range etc. When you check what modules have been updated you can see for example that it is just the camera or infotainment module so any claims for increased efficiency are just placebo.

Looking at your consumption screenshots I see nothing abnormal, consumption for 98km/h average is correct (as you found out even after a single traffic stop average speed plummets) that is why consumption is high at high speed, once you slow down it drops. If you spend the last minutes of your trip going slowly you will see a significant decrease in your overall "trip consumption".
As said average speed is only one metric and since this is not a lab test you have weather and terrain conditions working mostly against but sometimes for you. I can post a screenshot with high average speed and almost no consumption (one way coming down the mountain say 2000m elevation to sea level 0m). While fitness apps have elevation gain/wind etc. data this is not important for cars.

I am guessing the blue screenshot is the iX? Irrespective of that, BMW will always be more efficient than Porsche as they had a carbon tub EV in 2013 on the market. Their upcoming iX3 is what they refer to as 6th gen (iX is 5th gen) you can consider Macan 2nd gen after Taycan. BMW count their experience in hybrids as well so they make the generation gap appear larger.
Porsche is the last brand to consider when it comes to efficiency, the Taycans for example had massive wheels & tyres, massive presence/weight (for something so small inside) so consumption was always high.

You see my 110 average screenshot that was 58km 120 en then 3km to and from home ...
I just did a test with resetting the consumption and when trying to drive 120 over a 10 km stretch at 20C the consumption is 20 kWh/100km ...
So way more efficient then TeslaBjorn test ... I suspect the 20 inch wheels do have a bigger advantage then the calculator shows ... also higher temps make a huge difference ...

The iX is 300kg more heavy despite the carbon tub and running on 22's ... I dare say that BMW has the most efficient platform for the moment and I'm really curious for Neue Classe, though it will be a no go as the have nerved Apple CarPlay to the bare minimum central display ...
