So Audi has lower load capacity.
However, other pages at AutoBild.de show that Audi has higher load capacity.

So the load capacity is 600kg.
Jaguar XJ XJ8 4.2 Liter

Leergewicht 1615 kg
So the load capacity is 585kg,
less that Audi's 600kg.
I find similar load capacity contradiction in AutoBild's other comparison reviews.
I once sent them email, but they did not answer.
