How does the Cayenne Coupe's roofline affect its interior space and functionality?

The Cayenne Coupe's roofline has a significant impact on its interior space and functionality. While the Coupe's sloping roofline gives it a sportier appearance, it also reduces headroom and cargo space compared to the standard Cayenne. However, the Coupe's rear seats have been lowered by 30mm to compensate for the reduced headroom, and the rear seats can still be folded down to create additional cargo space.
