Now a day, gas price is sky high, people need to find an efficient way to increase the mileage for each gallon.

Fuel economy standards which established in 1975, hadn’t changed much since the mid-1980s. But now the Obama Administration is ratcheting up pressure on the auto industry to dramatically increase the average miles-per-gallon of each company’s fleet. Under a rule passed in 2010, carmakers were already on the hook to achieve an average 34.1 mpg across their fleets by 2016. This week, the government raised the bar even higher, to an average 54. 5 mpg by 2025. But the new standards will likely require auto companies to develop more hybrids, plug-ins and natural gas vehicles, while using more lightweight materials and improving traditional gasoline engines.

So far, the new mileage rules have generated tangible benefits for consumers, with few of the downsides opponents have predicted. “Without a doubt, the new rules have been a win-win for everybody,” says Jesse Toprak, of the car-research site TrueCar.com. “It’s a win for consumers, a win for manufacturers, and a win for the environment.”

The “Corporate Average Fuel Economy,” or CAFE standards, will vary by automaker depending on the mix of models they sell. The requirements will be lower for companies such as General Motors, Ford and Chrysler, which offer more pickup trucks. The standards can be lowered by the government if people suddenly start buying less-efficient vehicles in the future, although few expect that to happen.

How the automobile helps the customers to increase the gas mileage?

The very common technology we can see in many new cars, there is a Econ mode in lots of Europe cars. What it does is to shut down the engine while drivers are waiting for the red light of trying to pick up someone and just make a short stop at the airport. This technology benefit not just the user but also the environment, when the econ mode is on the engine shut off when the vehicle stopped, this helps to reduce the emission of carbon dioxide.  And here are some other examples from different companies, with different type of cars that have similar technology to benefit the driver and the environment. The 2013 Kia Rio, for instance, joins the BMW 3-series and Porsche Cayenne in offering a start-stop engine. That technology, once reserved for hybrids, saves fuel by shutting down the engine when the vehicle is stopped. Many cars, including the Mazda CX-5 and Volkswagen Golf, use variable valve timing to maximize fuel efficiency and performance. It was first seen on Acura’s exotic NSX in 1991. Others are offering continuously variable transmissions (CVT), which have no traditional gears but keep the engine at its most fuel-efficient RPM across a wide range of speeds. Cars with CVTs include the Infiniti JX, Nissan Altima and Subaru Outback. Aerodynamics also plays an increasing role in improving fuel efficiency. Modern cars like the Cadillac ATS, Dodge Dart and Ford Escape, for example, have shuttered panels in the grille that allow air to flow more smoothly around the vehicle, depending on speed and driving conditions.You can also buy a car that shuts down one or more engine cylinders when it is coasting, or cruising under a light load, reducing fuel consumption without sacrificing performance. Vehicles that offer this technology include the Audi S8 and Honda Odyssey minivan. Cars like the Buick Encore, Fiat 500 andLincoln MKZ, meanwhile, improve mileage through direct fuel injection, which injects gas directly into the combustion chamber in extremely precise amounts.

Even hybrids have changed. The Ford Fusion, Honda Accord and Toyota Prius are all available as a plug-in hybrid, while General Motors uses a smaller motor and battery pack to give a little electric assist to cars like the Buick LaCrosse and Chevrolet Malibu.
