A new survey on fuel economy has been released.
The survey by the Consumer Federation of America found most automakers have not made their cars more fuel-efficient, even as consumers say they want more.
The survey also found nine out of 12 major US automakers are offering vehicles that had worse miles-per-gallon ratings than they did 10 years ago.
More data from the study also says consumers blame financial problems at some automakers on their lack of fuel-efficient cars.
The Toyota Prius, a hybrid car, tops the list with 60 miles per gallon in the city and 51 on the highway.
The only US car on the list is the Ford Escape Hybrid with 36 and 31 miles per gallon.
At the bottom end of the ratings, European sports cars dominated.
If you are buying a Lamborghini Murcielago, be prepared to get just nine miles to the gallon.
