I totally agree with You on that. Which is why I love my CX-3 2.0 compared to my previous Fiat Bravo 1.4 Turbo (which was a very good engine, but with poorer mpg).
Unless the Honda 1.5 Turbo is a huge improvement on most other smaller turbos, real life MPG will be much lower than stated in the official test.
You may be able to cruise at a steady 75 mph and get good mpg, but as soon as You touch that pedal and the turbo spins up, it'll drink fuel at a much higher rate.
the Honda 1.5 Turbo is a huge improvement. Looking at the BSFC map it does well (better than the 2.0L skyactiv) up to ~100HP
Above 100HP the Honda burns fuel like there is no tomorrow.. but honestly.. 99.5% of the time (even when climbing freeway grades at 80PMH) my 2.0L skyactiv is using less than 100HP.
