Printed option prices only. A pack is counted once and makes the figure a floor when it carries no printed price. Nothing is inferred from the other car.
Plug-in hybrid fuel economy is shown as a hybrid (battery depleted) so it compares fairly with the other car. A PHEV's official "combined" figure assumes you start every trip fully charged, so real-world economy depends on how often you plug in. Electric range shows how far it goes before the petrol engine is needed.

For towing, the Porsche Cayenne leads with a 3,500kg braked capacity vs 2,500kg. That 1,000kg difference matters if you regularly hitch up.
