Yes, but BMW stunk on the Russian Front.
Porsche used to make the best model Panther, IIRC.
by the way, my memory was off. Porsche had the losing design for the Tiger. Henschel made the Tiger's chasis. The Panther was a MAN design, but about 4 companies made the chassis - MAN, daimler-benz, Henschel, and another. the engine for both the tiger and the panther were Maybach.
