    It would be really hard for Mazda to introduce a car with CVT, as it will degrade their performance credentials here as a "zoom-zoom" company. I wouldn't want them to go CVT honestly as they do make really good traditional automatic transmissions.
    .

    My own two cents here.
    First off, I'd like to personally thank Mazda for not introducing CVT's in their vehicles. I hate those things.
    It is one of the reasons (among many) that I went from being a Nissan guy, to never wanting to own one of their products again.

    I also find it highly amusing to see paddle shifters on a car that has a CVT. Shifting your own gears in a car that doesn't have any (gears, that is).
    It also amuses me just how hard car manufacturers try to program their CVT's to mimic a traditional torque converter automatic transmission. Fake shift points, etc.
    If the CVT is that great, why are they trying so hard to make it pretend it's not a CVT? I know, it's because CVT's suck.
    Thank you Mazda.
    Love my 6.

    Yeah, but they lost me when they dropped the REAL manual. At least in the CX-5.

    That is due to low sales.

    Unfortunately true. I mean I drove manuals for years and hate to see them go but if I was the guy at Mazda making the decision based on the numbers I’d probably make the same decision.

    Yeah, I know, it's over for manuals. It sure is fun to drive, even with the lowly 2.0L

    SkyActiv-X SPCCI is using compression ignition and spark ignition alternatively like a hybrid switching between electrical motor and gasoline engine. See this Driving Mazda's Next Mazda 3 with Its Skyactiv-X Compression-Ignition Gas Engine article from Car and Driver:

Should your acceleration needs outpace CIís operating parameters, the X switches to conventional spark ignition, the faintest hint of supercharger whine dancing among engine noises familiar to anyone who has driven a four-cylinder Mazda recently. Even under compression ignition, the engine is smooth and quiet; the engine behaves so similarly in each ignition state that it takes concentration to detect which one is in play. Traverse a smooth road at lower speeds in CI mode and listen closely enough, and you can just make out a diesel-like prattle. At higher speeds or on coarse road surfaces, youíll never detect it.

    I use to think that way as well, about paddle shifters in cars with CVT. However the one in the Accord Sport is actually useful if you know how to use it or what it is for. In cars with traditional automatic transmissions or DCTs, the paddle shifters simply allow you to change gear, up or down, pretty simple. In the Accord Sport, the paddle shifters allow you to select a different ratio that will give you more power or allow engine braking. That's the complicated answer, but I found a different, albeit simpler way to look at it. The paddle shifters in the Accord Sport allow you to select a higher RPM limit. Basically in my experience, driving it in D mode, the RPMs seem to be capped at like 4000 RPM even when you go WOT. This was most likely done in the interest of fuel economy. Using the paddle shifters to downshift allows the engine to rev up past 4000 RPM, which means you get more power, because in the 2015 Accord with the 2.4 NA engine, max power is at like 6500 RPM.

    So to give an example, I'm approaching a traffic light that's about to turn yellow. If I was in the CX-5 and wanted to beat the light, I would floor it and activate the kick-down switch for maximum downshifts and then zoom along. If I was in the Accord Sport, I would/could maintain my foot's position on the gas pedal and just hit the paddle shifter twice to downshift, which will immediately put me at a higher RPM and give me more horsepower. Also I'm not sure at what RPM it activates in D mode, but at higher RPM, VTEC kicks in and the car roars and actually pushes me back into the seat. If you put it in Sport mode (yes the Accord has Sport mode too), the car will actually go all the way up to redline, which is where the car makes the most power.

    The reason why manufacturers are trying to introduce fake shift points into cars with CVT is simply because people think it is unnatural for the car to not shift, even if not shifting and staying in peak power is more efficient than shifting and then having it climb the rev range again. People are just used to engines going up and down the rev range, along with the sound of the engine doing so, that driving a CVT car that is going fast but is stuck at 6500 RPM, makes it a weird driving experience. And it does feel weird when it happens, but only because we are not used to it.

    Read the article posted above. They aren’t using the spark plug in the same way. They ignite small fuel ball which raises the pressure causing the rest of the cylinder to spontaneously combust. That’s why it’s called spark controlled compression ignition not spark ignition.

    They also aren't using the supercharger the same way other engines do as well.

    Exactly, this engine is designed for efficiency not performance. And they’re using a lot of existing technology in novel ways.
