Lately automakers have found ways to make some seriously powerful cars produce surprisingly respectable mpg numbers to assuage their federally induced consciences, but there are some notable exceptions.

Among many of the most-coveted internal combustion chariots, it remains true that if you want it all, you will still have to pay. And pay again.

Most of the cars on this gas guzzler’s hall of shame could unashamedly accrue fuel bills in three years high enough to pay for an entry level car. And that’s the cheap part. Buying one of these champions of fuel un-economy may set you back enough greenbacks to purchase a decent house.

But this will not be your usual Top-5 ranking. The way this worked out is several offenders tie for the worst EPA-rated miles per gallon – so we’ll file them that way, by their combined mpg.

Bear in mind also, these official numbers may be optimistic. Just as a high-mpg hybrid may do only OK if driven hard, if one actually uses the powerful engines of vehicles on this list, expect single-digit mileage.

What elite carmakers are in process of doing, however, is coming up with novel hybridization strategies. Cars like the McLaren P1, Ferrari LaFerrari, Porsche 918 Spyder and more to come look like stars in the mpg test cycle when they need to.

And, their zero-emission electric motors even add to their powerful engines, which still can plummet the mpg when desired. None of those are on this list, of course, but rather what follows are conventional examples of the mature internal combustion carmaker’s art.
