Indeed, 86, 87 and 98, Porsche clearly won against multiple "big car manufacturer" teams, but that's only 3/16, and other years they've also lost against multiple "big car manufacturer". Saying Audi's wins don't stack up against Porsche's is silly, as it's comparing apples to oranges of different eras. Porsche have had some impressive wins, some less impressive wins and some embarrassing losses. Audi have competed at Le Mans during far fewer years in a different era with different competition. The comparison makes no sense to me.
