i am getting a cx 70 as soon as it is released. there is a rumour floating around that there might be a twin turbo version of the inline 6. but it is only a rumour.
That would be a big change away from the SkyActiv X engine then. More of a regular SkyActiv engine.
The SkyActiv X uses a supercharger to facilitate the HCCI. ( Homogeneous Charge Compression Ignition ). That is something Mazda worked on for many years and finally achieved.
