Is the Mazda 3 engine the same as in the BMW 3 series?

My girlfriend claims the Mazda 3 engine and the BMW 3 engine are the same, I don't believe her, as I know Mazda is owned (partially owned?) by Ford, and to my knowledge, neither has anything to do with BMW, but she is absolutely adamant that the Mazda 3 engine is made by BMW

They are nothing alike. The Mazda 3 engine is developed by ford it comes in several version starting from a 1.3 liters to a 2.3. I have a 2007 BMW 3 series and it comes standard with a 3.0 (In Europe it comes with a 2.0 but not in the US) liters engine, something that Mazda 3 does not even offer.

Here is a link to the information on the Mazda 3 engine information http://en.wikipedia.org/wiki/Mazda_MZR_e...

BMW and Mazda are nothing alike!

The Mazda 3 engine is a relatively old FORD engine design that has no real ties to BMW.

Its one of the 'new' Duratecs that have been available worldwide for years, but in the US they were originally called Zetecs. Due to the issues of the Zetec in the Focus (mostly from the manufacturing being done in Mexico) theyve changed the designation to Duratec worldwide now.

The closest link comes through Cosworth. They have worked with BMW in the past, and they are almost entirely responsible for the Duratec style engines.
