Lots of Panthers were lost due to Transmission/ gear failures and engine faults. This was due to a lack of testing and the rush to get the vehicle into service.

The Tiger seems to have been more reliable but many were lost to mechanical faults.

T-34... think the engines in those things never broke down!!!

Also consider the differing crosscountry performance between the tanks, and dont forget the majority of german tanks would have been III & IV.
