Haitoman 110 Report post Posted July 5, 2016 (edited) Well that's a tricky question but easily answered. There is mechanical horsepower (HP as we know it) and metric horsepower (PS). As we are talking Germany they are quoting metric horsepower. The output of a MY10-13 F10 535i is 306PS (metric horsepower) or 302 (mechanical horsepower). So 306 metric horsepower plus 77 (metric) horsepower for the piggy back = 383PS or simply 'HP' as the Europeans just assume everyone speaks metric. Same deal for newton metres - the Jerries are speaking the metric equivalent of ft/pounds. Edited July 5, 2016 by Haitoman 1 Quote Share this post Link to post Share on other sites
