Note that the manual transmission Sport trim (available only in the USA as a 6MT car... no longer available in Canada
) does not have the cylinder de-activation that the automatic transmission variant of the non-turbo engine has. That is either an advantage, or a disadvantage, depending on your point of view. Me, I like simple, stupid - I would rather NOT have cylinder de-activation (as for me, it is not yet proven to result in no engine wear ramifications for the de-activated cylinders).... It does save some gasoline, though.
Speaking of the savings of fuel, I think the Energy & Natural Resources fuel economy test in Canada (and possibly the EPA fuel economy test in the 'States) un-naturally lowers the reported fuel economy of manual transmission cars... as it arbitrarily makes the test driver shift gears at certain rpm's (i.e. the test regime). This is unlike what you would typically do if you drove the car normally. Contrast that with the automatic transmission variant, the automatic is left to its own devices. What this means, for instance, is on a down-gradient slope (i.e. going down hill) - normally driving, you would shift your manual transmission to a higher gear, earlier, than the Fuel Economy testing regime would have you shift. It would by contrast make you shift gear at a certain rpm, notwithstanding what the shift-light tells you to do.
This is my understanding, but I cannot vouch that it is correct.
Oh, BTW, I was ' kinda worried that the 6MT car no longer would be available in Canada for MY 2018... That's what spurred me to get my '17 GX model, 6MT (my GX is similar to "Sport" trim - but it does not have leather wrapped steering, but DOES have four heated cloth seats, rear camera, heated mirrors, rain sensing wipers, federally mandated daytime running lights).
