As I understand it, the supercharger is to give the bottom end power/torque until HCCI kicks in.
InterestingFrom the R&T article:
"In this case, the supercharger is being used to lean out the air-fuel mixture, a lean supercharger, if you will, to improve fuel economy. This reduces combustion temperatures, lowers NOx emissions, improves the amount of useful work produced with the same amount of fuel, and reduces heat loss to the cylinder bore."
The other thing from that article that is interesting is this:
"If Mazda had it their way, they’d be running 80 octane fuel in their SPCCI engines... Using a higher octane fuel would in this case make combustion more difficult."
Here are my impressions with the new 2017, coming from a 2016:
No doubt, the 2017 is a lot quieter and more refined to drive. Noise levels inside are greatly reduced over the 2016. The interior is more elegant and upscale. It is also more comfortable to drive. I don't get as "tired" as I did with the 2016 when on the highway for 30 miles or so.
As far as handling goes. Not sure yet. Haven't taken it through the turns or pushed it hard in the corners.
All-in-all, I really like the 2017 over the 2016.
My 1st 30 mile trip I averaged 34 MPG.

Btw what happened with your 2016? Any steering/throttle feel impressions?
Not only are they led but the brake lights are a combination of a brighter version of the “predator” lights and a cluster of led jewel lights. They are excellent.
I know. If the technology takes off and other car manufacture adopt it, I wonder if the gas companies will start charging more for low octane fuel than for high octane fuel!
Above poster stated that the 2017 Touring does NOT have LED brake lights. Not sure now
It does have LED reverse lights but it's hard to tell if they are LED brake lights.
Handling should be a bit less that 2016 model as they have improved ride comfort
I remember the MotoMan YouTube video of the ‘17 CX5 and Dave Coleman said that he wished that they would have put the 2.5t in instead of the naturally aspirated but higher ups prevailed.
I think SkyActiv X is the engine to watch with its supercharger.
Different design aspect. Don't know the power output of each. Maybe Anchorman might have this information.I noticed the LED lights on the 2017 are different than the lights on the 2016. The 2016's seemed a little brighter but the 2017 I have doesn't have the fogs but I am sure it's more than that.
No reason to assume that. They are not mutually exclusive.

Thought you mightI’ve got a pdf somewhere!.........
