Ill try to explain why I can say it "It sucks. Simple as that"
I you were from Norway and had to pay 10K USD more in CO2 taxes compared to say, the engine in Cooper S (GT86 gets about 350% higher CO2 taxes). You would probably say, that it sucks to pay that much more. Hence, you could easily say, the fuel consumption sucks. Yeah, the taxes suck, big time! But they are related to the fuel consumption.
If you are able to understand the reasoning behind that from where you are sitting. You would probably understand it 10x better if you lived here and have pay that yourself.
Ill give you another argument. Here is the EU rating system for CO2. GT86 is at 181g. Rated "F". I know there is A+ rating too.
A+ -8
A - 7
B - 6
C - 5
D - 4
E - 3
F - 2
G- 1
If I were to rate a movie that sucks from a scale from 1-8. I could give it a rating of 2. Which is an "F". Same as the rating of the GT86 on the official CO2 standard thingy (picture).
Another one:
Future EU CO2 goal are 85g per km for new cars sold in 2020.
Having a car that is rated at 181g.. That would suck.. Not just a little either.
By looking at standards in the not to distant future you would actually have to sell 1 electric car for every GT86 sold. And still the CO2 goal would not have been reached... Why? Because fuel efficiency of 181g CO2 would suck..
Another one:
Basically every modern 170-250hp fuel efficient engine in a car with simular weight as the 86 are rated "C" or a good "D". And most of them have way more power available.
Another one:
On paper the Cooper S only have a little less HP, and a little more torque compared to the 86. The engine in the Cooper is already some years. And the new model should be able to output more power and have 15% less fuel consumption..
For those who are not aware. Ill post this once more.. On same dyno:
Compare power at 4k rpm. Compare fuel efficiency 136g CO2 and 181g CO2.
If the engine in my cooper one day had the same power at 4000rpm as the 86, and worse fuel consumption. That would suck! There would be something seriously wrong with the engine, and I would have visited the dealer right away.
General stuff:
I would say cell phone camera sucks compared to full frame DSLR.
I would say cheap surround system would suck compared to a decent home cinema.
I would say a no-name budget tv sold from a food chain sucks compared to high-end model in the same size.
Many people would say the differences are subtle. I would say the difference are huge and that the the bad stuff sucks.
Deslock, I remember you from GT5 competitions earlier. I dont know about you. But if my laptime on Nordschleife is off by 0,7%, that sucks for me. I still think people who are 5% slower than me have ok lap-times.
But if someone can post laptimes 1% faster than me. I feel I suck compared to them...
It all depends on your point of view.
Hope some get my point of view.

People are allowed do disagree!
Moral of my post: What sucks for some are subtle differences for others..
