Early 1941 the Russians were thinking of a better T-34, the T-34M. It had better armor, a commander cupola, more room for ammunition.
Anyway, the new engine did not get ready in time and no further delays were allowed for the T-34 production.The war stopped the building of T-34M finally.

But nice details to know that this might have happened in 1941...
