So where is the promised SkyActiv-X HCCI / SPCCI 2.0L??? Isn’t it supposed to be the future of the Mazda with break-throuigh technology on BOTH horse power AND fuel efficiency???
Any modern 3.0 ~ 3.5L naturally aspirated V6 can get ~300 hp and torque. Now SkyActiv-X 3.0L I6 needs some help of supercharger + 48V motor to achieve that? Unless the setup is super fuel efficient, with the complexity of the SPCCI, I don’t see any future of it, just like the SkyActiv-X 2.0L.
Its in other countries in their small cars (mazda3) which we know is not selling well in the U.S.
It would not make sense to offer it in their top U.S. selling vehicle the CX-5 as it would be too slow for the price point. Their strategy is to offer power in the U.S. hence offering the 2.5l turbo engines in virtually every car in the U.S. (CX-30, Mazda3, Mazda6, CX-5, CX-9). Remember, Mazda despite not selling high volume of cars in the U.S., has an uncanny ability to have a good amount of their sales being upper trim models. How ironic Mazda...bring back MazdaSpeed!!!
Ok so Skyactiv-x..... First of all the supercharger is not there for power but rather to provide leaner air/fuel in the high RPMs.......for better mpgs and quite possibly to even work in the first place. Yes, not only does it provide peak torque sooner compared to Skyactiv-G it now provides a wider power range band and likes to be revved into 6000 RPM territory. Its already more mpg efficient than the Skyactiv 2.0 at 90% of the power of the 2.5 gas engine. The 48v hybrid add on will boost mpgs. The larger displacement to provide more power (in the inline6). They've already tested the Mazda3 Skyactiv-x getting 40+ mpgs while doing aggressive real world driving including 100mph sprints in the autobahn. Not sure of the official MPG numbers but I see 45-50mpgs thrown around. Max speed was 134 mph which is further proof this engine won't die off past 5000 RPMs, that chassis is legit, and we need to use our tax dollars for better roads lol.
In the U.S. I predict in the next few years the 2.5l as the entry level engine (later to be replaced by 2.5l skyactiv-x?), then the next step up is the 2.5l turbo (or maybe the other way around?), and then the inline 6 skyactiv-x hybrid. This pathway will allow Mazda a bridge gap into both meeting the strict EPA requirements as well as increased presence in the entry luxury class.
