at an altitude of 1800 m and rated there at 245 hp. This would theoretically correspond to rating of about 300 hp at sea level; however, the engine was not designed to withstand such power - it needed to be carefully throttled down at low altitude, so it would not exceed the safe level of

Like all engines of that time, the previous
Maybach design, the Mb IV, lost as much as half of the nominal power of 240 horsepower at high altitude. The new Maybach Mb IVa of 1916 was the first engine designed to overcome this limitation. It did not use a

The engine was falsely given a rating of 260 hp (190 kW) at sea level, so it would not appear inferior to the engines it replaced.
