Check out www.fueleconomy.gov for yearly information on all US cars fuel ratings. Any hybrid car (Honda Insight, Toyota Prius) will have excellent fuel ratings. Also, turbo diesel engines by VW do very well. Both the VW New Bug and the VW Golf models with TDI engines get 42/49 for the last few years.
Here are more opinions and answers from other s.com members:
Hybrids have been proven to get poorer fuel economy than diesels in "real world" operation, especially in the relatively flat interior of Australia. Petrol hybrids are "in their element" in the cut and thrust of city driving, not on the open road.
For Fuel Efficiency, a Prius.

If the second car has a fuel efficiency that is 45 percent of the first car, we first need to determine the fuel efficiency of the first car, which is 15 km/L. To find the fuel efficiency of the second car, we calculate 45% of 15 km/L: (0.45 \times 15 = 6.75) km/L. Thus, the fuel efficiency of the second car is 6.75 km/L.
The best features of a 16,000 car typically include good fuel efficiency, modern safety features, reliable performance, and a comfortable interior.

Websites like fueleconomy.gov compares car with the best and worst fuel economy to help consumers determine the best car for them. Some good fuel efficient cars are 2009 Toyota Prius and 2011 Honda Civic Hybrid.
Fuel injection gives the best air to fuel ratio for best performance and efficiency.
A car that runs on fuel cells only has a similar overall efficiency to a car that runs on petrol because a car that runs on fuel cells is designed to not pollute the Earth but you need renewable energy resources to generate the electricity which is like the efficiency of the petrol pollution. That was what I put on my homework anywayz. :)
The 2014 Chevrolet Cruze delivers strong performance and a high-quality, roomy interior for a compact car and it has the most fuel efficiency.
"The best affordable small car is the Hyundia Elantra. It combines a base price of $14,830 with fuel economy ratings of 29/40 miles per gallon city/highway and stylish design."
Fuel efficiency for SUVs is not one of their strongest suites. At best for an SUV, you're looking at getting around 18 miles per gallon of fuel you put into the gas tank.
