I just don't follow Mazda very much.
But in the last two years, it's very rare to get a new engine with displacement >1.6L, that's not been turbocharged, outside a few exotics (F12 and Viper come to mind)
My current car is a 2012 model, with a "new" (i.e. significantly redeveloped) engine, that's a 1.6 N/A, and many reviewers chided it for being anachronistic, and lacking the turbo midrange torque they've so gotten used to.
And again, the RS Clio, the last generation's hot hatch bastion of natural aspiration has been replaced by a turbo this year. So the "car" market is definitely moving towards turbos. That Mazda is an exception is something I did miss - but then I don't care much about Mazda, because all they're known for lately is the CX-5 and fishy design language on the latest models.
The Clio was always putting out around 160 HP/ton, if the MS3/3MPS can match/beat that, all is well. If it can't...well, I'll be rather recommending a Clio 197....
