PORSCHE Macan EV ( flow separation )

There's a very brief segment in which you'll see the smoke- flow separation behind the Macan's OEM roofline, then how the pop-up rear spoiler reaches up to help mitigate the offense.

Isn’t the purpose of that steep spoiler lifting up for downforce? Hence when they mentioned it for dufferent driving conditions?

Sorry, I don't, only what I posted. I grew up 'pre-home computer', and can barely function as it is.
I had 'GOOGLED' Porsche Macan EV aerodynamics, and this video popped up.

Probably.
--------------------------------------------------------------------------------------
Past Porsches have 'killed' some of their 'customers', and since the Audi TT debaucle, Porsche Group and corporate 'sister' Audi and probably other VW division have also added rear spoilers as palliatives for separation-induced rear- lift instability.
* The 1972 911 Carrera RS 2.7 was an 'industry first.'
* The Porsche Panamera has it.
* Audi A7.
* Bugatti Veyron, Chiron
* VW's Bentley division's fastbacks conspicuously do not have rear spoilers, in spite of 190+ mph top speeds.
--------------------------------------------------------------------------------------
As the Macan is the top-selling Porsche, and it's the first Porsche ICE-to-BEV conversion, the Pseudo- Jaray roofline creates 'range anxiety' issues because it's aerodynamically 'dirty', compared to 'Taycan', 911 GT1, and the Porsche 918 for instance.
I suppose Michael Mauer allowed the styling to deviate as much as he dared, so as to not scare off buyers.
And Walter de Silva, who watches over all 'Volkswagen AG' design products also signed off, so, VW is just going down a familiar road.
-------------------------------------------------------------------------------------
To compete against the benchmarked Tesla CUV, I suspect that the Macan's spoiler will have a 'minimum-drag' setting to protect battery range, and a 'safety' ( 'direct-downforce' ) setting, to keep customers alive on the few remaining unlimited-speed portions of the Autobahn/ Autostrada.
Porsche is targeting the Macan EV to be the 'highest-performance' CUV in it's market segment. If it's range 'stinks', their hoping that 'fast-charging' will swing consumers.

I started from scratch again.
I'm using a computer at the local public library.
It only has GOOGLE CHROME for a search engine.
--------------------------------------------------------------------------------------
I did a SEARCH for:
' 2024 Porsche Macan EV aerodynamics' , Video
--------------------------------------------------------------------------------------
The very first video to pop up is the one I linked to.
It's from, The WHEEL NETWORK, from two weeks ago.
It has a 'GOOGLE' address.

Macan's sister's drag

The Macan's sister, the Audi Q4 E-Tron, built on the same Porsche MEB platform architecture ( VW ID.3/ VW ID.4/ VW ID. Buzz ) has Cd 0.28 for the 'Rakeback' roofline, and Cd 0.26 for the 'Sportback' roofline, compared to the Macan's Sportback's Cd 0.25, with the pop-up 'wing' as it's drag-minimum angle-of-attack.
Volkswagen wants Porsche to remain the 'sportiest' among it's divisions, short of it's Bugatti and Lamborghini brands.
The Cd 0.34, Volkswagen-Lamborghini Urus SUV is in a in a 'larger' SUV market segment, so it's not competing directly against Volkswagen-Porsche.
Volkswagen-Bentley will probably also create a new aspirational BEV SUV, below it's Bentayga, based on the same MEB platform.
