Not according to the website below......even if you don't believe the absolute number as it can change with dynos.....look at the relative number between BMW and Audi......

BMWs rock because they took huge measures in reducing the rotating resistance of the engine...stuff like electric pumps / clutches for accessories.... it is good enough to expose the true loses from the tranny / axles... whether you believe 6, 7, 10, 14% loss....look at the relative numbers.
