Yep, I'm definitely confused.
For one thing, I wish that Fiat had come up with better names for their technologies than Twinair, Multiair and Multijet. They sound too much alike, and don't suggest the fundamental differences between them.
I suspect some writers may have gotten them confused as well.

  It won't be diesel, that's for sure. 1.4 is Multiair, multijets are 1.3, 1.6 and 2.0.
  New car will have sleeker body and lower height than 500, so it'll get lower aerodynamic drag.

  Fiat 500 does 70 mph at 2900 rpm
  Alfa Giulietta with manual does 70 mph at 2700 rpm
  Alfa Giulietta with TCT does 70 mph at 2400 rpm. TCT (like vw dsg) - dual clutch automated manual with tall gearing.
  I guess that lower drag and lower rpm on highway will yield couple of extra mpgs.

  We know that they'll put TCT in Chrysler 200, so it'll be shame not to put it in "new C car" and improve mpg.

Having read what brankobox has said, I think he may WELL be onto something there and as for the XXXjet/air nomenclature, I generally don't get them mixed up, it's when I don't pay close attention and let my mind mis-parse the text I might get them mixed up temporarily. When I read TwinAir, I know it's the new 2 pot motor, MultiAir is the variable valve variant of the gas motors and MultiJet for the diesels.

In essence, either a tweaked MultiAir motor of say, 1.4L displacement in perhaps turbo form OR a diesel, but he says it may well not be the diesel, but who knows though with the larger sized MultiJet II diesel being fitted to the new Jeep Grand Cherokee.
