Yes, indeed. But that is essentially the last model in their fleet which still uses borrowed or co-developed engineering.
Mazda is fully independent now, and Skyactiv tech was fully developed in-house and utilizes zero Ford componentry.
Ford actually took with them Mazda's early GDI tech, as found most originally in the 2006 MS6, sold in 2005. Sure, they made advancements, but believe it or not, FoMoCo borrowed heavily for their earliest EB engines.
