lol classic import guy arguement. My motor is more efficient and powerful then yours per liter. So I have a solution. Why don’t we get a tug of war between you and the other TDI owner all hook chains to underboosteds dually and see who wins. In all serriousness of course a TDI can be optimized to make the most power possible since it operates underless stressful conditions. A roughly 9k pound truck is rated to pull 21k pounds, over twice it’s own weight. Far as I know no TDI can do that. Different purposes behind each power plant.
Well comparing towing capacities is like comparing apples to oranges. There isn’t really much that can be compared between the two other then power figures…
