An interesting development, for sure.
With most of our cars, particularly the older ones, we’ve met or bettered the claimed fuel economy which, as far as I’m concerned, means we must be meeting the emissions targets as well. You don’t get emissions without burning fuel.
Then with our Giulietta 1.4 MultiAir we get nowhere near the claimed fuel economy - something like 60% more, in fact - and so I doubt it’s anywhere near its claimed emissions. Of course the car has been checked over and over again and seems to be running as well as it can.
Something has to give and if that’s a new testing regime, fair enough. I do feel bad for everyone who bought into FIAT’s bold claims for the TwinAir at about the same time as their bold claims for the MultiAir, maybe they figured out a way to cheat the tests at that time.
Meanwhile with my older-technology Abarth 500 returning similar economy to our 500 Lounge but rather more performance, I feel that in the real world it can be considered ‘very economical’. Much lighter on fuel than the (heavier, larger) Giulietta anyway. We’ll see whether this translates to good results in these new tests. I imagine it won’t, because the 1.2 will seem to be better even though you get less than half the power from it, so it’s not really a fair comparison unless driven to achieve the same performance. At the end of the day, it’s down to the driver, and I wonder if the testing will capture that.
