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.
