MTU Friedrichshafen is a brand of Rolls-Royce Power Systems. Their drive systems and large diesel engines, for example, properly heat up ships, heavy and military vehicles or railways.
It is not uncommon for such drives to have outputs of up to 13,600 hp. The mega-diesels are manufactured in the idyllic Friedrichshafen on Lake Constance, but the engines "Made in Germany" have long been used worldwide.
