In today’s economy, saving money is on top of most peoples’ minds. With gas prices creeping up, finding a car that is not a gas-guzzler is important for your financial bottom line. Cars that have been known to have poor gas mileage in the past, such as sports cars and SUVs, are becoming less and less popular as people are trying to save money and be good to the environment.

Fuel economy is stated as miles per gallon (mpg). This refers to the amount of miles you are able to drive with one gallon of gas. The mpg values differ according to what type of driving you are doing. Driving in the city usually results in lower gas mileage than on the highway. When talking about combined fuel economy, both highway and city mileage are combined to form an average. The following cars are 2012 models that will help save money at the pump.

Best Gas Mileage for Smaller Cars

If you like smaller cars you may be looking at two-seaters, minicompacts, subcompacts, or compact cars. If you like a two-seater, the Honda CR-Z gets 37 mpg. The CR-Z is available in a sport model as well as a hybrid, which will get better gas mileage of the two.

For minicompacts, the combined fuel economy for the Scion iQ is also 37 mpg. Even though it is a small car, there are a number of great features and the design has been called both intelligent and modern.

For subcompacts, two cars average the same mileage. At 33 mpg, you can choose from the Chevrolet Sonic 5 or the Ford Fiesta FWD. The Sonic is available in both a two-door hatchback and a four-door sedan, depending on your needs. The Ford Fiesta is available as a sedan or hatchback as well, although both of them have four doors.

A Toyota Prius is a great choice in regards to fuel economy. There is a Prius Hybrid in both compact and midsize. Both cars get a combined fuel economy of 50 mpg. Safety features include traction control, stability control, brake assist, anti-lock brakes, and smart stop technology. They also have multiple airbags, active headrests for the people in the front seats, and three-point seatbelts for everyone.

Best Gas Mileage for Large Cars

For a large sedan, the Hyundai Sonata gets a combined 28 mpg. Along with getting good fuel economy, the Sonata has received the top safety award from the Insurance Institute for Highway Safety (IIHS) for its anti-lock brakes, multiple airbags, and crumple zones in the front and back.

If you like cars with a bit more cargo room, there are a few station wagons that get good gas mileage. For small station wagons, both the Volkswagen Jetta SportWagen and the Audi A3 get a combined fuel economy of 34 mpg. The SportWagen is a top safety pick of the IIHS, and the Audi is always a good choice for both safety and looks.

For a midsize wagon, you can choose the Toyota Prius V with 42 mpg. Along with its great fuel-efficiency, the Prius V has a lot of cargo room, especially when you take advantage of the 60/40 split in the rear.

Fuel Economy of Electric Cars

In an effort to use less gas and take care of the environment, a new class of cars has emerged and they are the electric vehicles. These cars are powered by an electric motor that gets its power from battery packs that are rechargeable.

Although they don’t use gas like internal combustion engines, the U.S. Department of Energy has analyzed the amount of kilowatts per hours it takes an electric car to go 100 miles and has shown what the equivalent would be in miles per gallon, to get an idea of how an electric car can significantly help improve fuel economy.

Three vehicles were analyzed for their fuel economy. The Mitsubishi i-MiEV is a subcompact car and gets an equivalent of 112 mpg. A midsize electric car, the Nissan Leaf, gets an equivalent of 99 mpg. The compact Chevrolet Volt, which is actually a plug-in hybrid, gets an equivalent of 60 mpg.

Cars with the Worst Fuel Economy

If you are concerned with the amount of gas your car uses and are looking for a vehicle with good fuel economy, you will want to avoid certain cars. These vehicles are some examples of cars that get poor mileage.

For smaller cars, both the Aston Martin DB9 and DBS get a combined fuel economy if 13 mpg. Coming in with 14 mpg are Bentley’s Continental, Supersports Convertible, and GT FFV. Additional poor fuel-efficient cars in this class are the Mercedes-Benz CL600 and CL65 AMG and the Rolls-Royce Drophead and Phantom Coupe.

The midsize Bentley Mulsanne gets 13 mpg. For larger cars, the Mercedes Benz S600 and S65 AMG, as well as the Rolls-Royce Phantom and Rolls Royce Phantom EWB all get 14 mpg. The Cadillac CTS Wagon, which is considered a small station wagon, gets 14 mpg, while the midsize wagon Mercedes-Benz E63 AMG gets 18 mpg.

Of course, if can afford any of these cars you probably don’t care about the price of gas but for most people it’s important to check the fuel efficiency ratings before buying any car. A couple dollars here and there can really add up.
