VarioCam is an automobile variable valve timing technology developed by Porsche. The intake and exhaust camshafts in all Macan models with petrol engine are each equipped with a fully variable vanecell controller for continuous timing adjustments. A la place ils utilisaient un simple ressort et un tendeur de chaîne hydraulique dont la fonction était simplement de maintenir une tension constante de la chaîne.
