How much percent was the most Ford owned of Mazda?

They owned 33% at one time. But supposedly Ford has owned more than 45%.

F series trucks have ford engines and transmissions lmao, take a look at mazda ecu's they are eec series since the courier days. Atleast in america they have ford engines.
like all of the big 3 ford farms out their small car platforms. Ford uses mazda and nissan. As for ownership, who knows.

Hi they also have investment in hyundai and kia, ford has owned land rover and jaguar hence why it is such a mess. Some poor jaguar owners have had to suffer the X type and S type based on the Ford mondeo.

Ford has owned more than 45%.

Ford owned 33.4% of Mazda at one point in 1996. That's the biggest stake in Mazda Ford ever owned.
