I read about every article I could get my hands on when Mazda severed ties with Ford and came out with Skyactiv...just do some Google searching of old articles from 2012 about Skyactiv technology. Go on YouTube and watch old videos about Skyactiv from 2012 as well. All the skyactiv technology was developed new from the ground up. Everything, chassis, engines, transmissions, literally everything was new from the ground up. Never did they merely upgrade the old C1 global platform or the old MZR motors and transmissions. Like I said before the only automaker today who still produces MZR motor blocks and the C1 global platform is Ford.
