There was not a single hint or indication of any turbocharger hardware / comment / interview from the reveal. There was also not single detail about the powertrain.
Mazda's Facebook page confirmed 100kg lighter, or 220lbs. 2480lbs on the lightest NC, making it a 2260lb ND.
However...
There is confirmation in the UK and Japan that they will be getting 2 engine options, a 1.5L that is good for somewhere around 130-140hp, and a 2.0L engine that is good for somewhere around 170-180hp.
Both are SkyActive engines, Mazda isn't doing any other type of engines. The whole SkyActive name applies to more than just engines too, so the entire car is "SkyActive".
There is also a comment from one of the engineers that "the US wouldn't accept a lower output engine", so either we will get both options too, or all options will be the 2.0L
I assume that the 100kg lighter comment is comparing the lightest NC variant to the lightest ND variant, which would mean that the 100kg lighter number applies to the 1.5L engine. Looking at the CX-5 2.0L vs 2.5L, there is 103lbs of difference, which accounts for the moonroof and other features too, so call it maybe a 50lb weight gain for that extra half liter. So the 2.0L should be around 2310lbs, giving it a power to weight somewhere around 12.5lbs per hp, vs 14.8 for the current NC. Noticeably faster with just peak numbers, but all the low end torque increase from the high compression SkyActive engine will make it even faster than the peak numbers suggest.
I'm excited. It may have bumped the Boxster from the top spot on my 'want' list. Pending an actual drive.
