Isn't the Sagaris a supercar? Hell to me being in America all TVRs are supercars.
Directed to M-Spec
Sounds to me like one. Then again, so does the Z06.

As for m-spec's mpg ratings well Ive got 3 sources which put the c6 at 13-15mpg. Ive got a whole book and 3 websites about porsches 911's getting about 22mpg and the m5 gets worse mpg than the c6,the audi rs4 gets just a tad better mpg than the c6 and all exotics such as lambo and ferrari, true cars in which mpg doesnt matter all do worse than the c6.
First off, let's have an apples to apples comparison here.
Fuel consumption is closely related to engine power output. (Other factors include gearing and rolling resistance (weight is a factor in rolling resistance)). Generally speaking, the more power an engine makes, the more fuel it will consume. In other words, the more power a car makes, the less likely it will get good gas milage.
So of course a Z06 doesn't get the same milage as a BMW 330Ci. IT MAKES TWICE THE HORSEPOWER. A 997 Carrera
may get 22 mpg if you drive it like a granny, but it is down 200 horses, isn't it???
All the cars I listed make similar power ratings to the Z06. Performance wise, they are all direct competitors. Yet, the Z06 manages to get better milage than all the others, but makes more power (Viper excluded). I'd call that pretty impressive engineering.
As for your sources, again you have to have an apples to apples comparison. It is very easy to get crappy gas milage. Just drive a car in bumper to bumper traffic or take it out on a B-road and drive the piss out of it. It'd be child's play to get 9 mpg out of a 911.... at a track, where you are redlining every gear and going WOT at every opportunity.
With the exception of the Saragis and M6, I used official US EPA numbers. They have strict procedures to determine this number. In most real world driving, it is likely less. HOWEVER, the important thing is to understand they are tested uniformly, so if there is a variance vs. real world, it is the same variance across
all the cars.
Finally, the Z06 is a sports car. It can also be called a supercar. It certainly performs like one. Whatever you want to call it, doesn't really make a shred of difference.
