Hi,
I am following the forum closely, as a future owner of a Porsche Macan 4s (ordered mid-December, delivery expected before the end of March 2025).
I'm a new member of this forum, and I'm normally never an active member (more a spy reader
). So, my apologies if I don't do the thinks correctly.
I preferred to create a new threads instead of use an existing one and add my contribution. Some of them treat the consumption by owner feedback, some other are more focused on the cold temperature impact. But this not really the subject I want to treat.
So I wanted to give my opinion on consumption expectation by approaching it in a more "scientific" way.
There are many elements impacting the consumption, they have been mentioned on several threads on this forum, so I will not mention them again.
I will only focused on some keys elements and provide a theoretical consumption analysis based on them.
The first topic I want to address is the WLTP protocol used in Europe and largely mentioned in this forum.
There is a lot of feedback regarding the unrealistic consumption value provided by this protocol. And this is true if we refer to the final value. Now, we have to understand the detail behind this final value.
The WLTP protocol is divided in 4 segments:
As you can see, most parts of the protocol are done at low or mid speed and only 14% at "very high speed". This explain why we never achieve the WLTP value.
The element that could be interesting is to have the consumption for the different segment of the protocol. This could permit to have an idea of the consumption based on our own conditions.
Fortunately, the Porsche Macan configurator provided these values based on the chosen configuration (at least for the EU version).
Herewith an example based on my own configuration:
As we can see, for this car the WLTP value is 599km (374miles). But the consumption for the Very high speed segment (representative of highway) is 23kWh given 413km (258miles).
These values being for perfect environmental conditions.
The second think that impact the consumption (and the range) is the aerodynamic elements (mainly the rims, but some other element has also an impact like the sunroof, ...).
Herewith a table that shown the impact of the rim size on the consumption:
Here, we can see that a Macan turbo with 22" rims has 368km (230miles) compared to Macan 4s with 20" rims (413km - 258miles).
The third element that impact the consumption is the temperature.
I used ABRP data's for Macan 4 to do the analysis.
There is 2 temperatures elements that impact the consumption: the external temperature and the vehicle temperature.
For example:
If the exterior temperature is -10°C and the the initial vehicle temperature is 20°C, there is a coefficient on consumption of 1.163 (+16.3%).
If the initial vehicle temperature is 0°C, the coefficient on consumption will be 1.163x1.194 =1.388 (+38.8%). This explain the high consumption with cold temperature for short distance.
The last element that have an impact on the consumption is the tires efficiency.
Based on what I found on the web, It is commonly accepted (A --> B means +5% consumption ; A --> C means +10% consumption).
I will finish with an example (a worst case, for sure
)
Macan Turbo 22" rim (spider RS)
Highway; external temperature = -10°C; initial vehicle temperature = 0°C; Winter tires (C label); short distance.
Expected consumption : 25.8kWh*1.163*1.194*1.1=39kWh. This means a range of 243km (152 miles) !!!
We can see that there is a big variability of the consumption, based on the configured elements and the external conditions. This explain the difficulty to have a clear view.
I apologize for this long message and sorry if I bored you, but it seemed important for me to provide my contribution to this consumption topic.
I hope this will help some people to consumption.
