2018 Mazda3 to Introduce HCCI Engine, Promises 30% Better Fuel Efficiency - autoevolution

HCCI is great in theory, but challenging to control. It's awesome that they will have this in production...

but there is no way I'm buying one of these until they have a proven track record of reliability.

As opposed to some shadowy group asking for investors so they can build a prototype.

"Mazda (Ford)"?

Ford lost controlling interest in Mazda about eight years ago, and they now only have a strategic partnership. Mazda is as much "Ford" as it is "Toyota" at this point, and I believe the SkyActiv engine development is strictly done by Mazda, only being developed after it was sold off by Ford.
