Did you know?
Henry Ford believed in the future of rotary engines and went to Mazda to buy the engine construction know-how.
And guess what... They refused to share this knowledge.
-Actually he died in 1947, Felix Wankel created the first examples/prototype in the 50's with NSU. Mazda worked on the concept later on so he might have had an interest in the patent maybe but never lived to see one actually work so not sure where you're getting that 'did you know' from...
