After the new fuel-efficiency requirements from the American government have been announced the designers of many auto manufacturing companies started working on new projects which would help to meet the minimum of 35mpg by 2020.

Hybrid cars are the leaders of the bunch, because they already offer big savings and smart fuel usage. Another option for customers would be diesel vehicles: although they used to be popular in the 1970’s and 80’s, due to air pollution programs their number had to be significantly reduced. However, leading manufacturers such as Mercedes-Benz and BMW have come up with bio diesel and several advanced filter technologies which reduce the emissions and make diesel vehicles friendlier.

For more options on fuel saving a customer can look at vehicles with:
• Internal combustion engine that starts working by sucking air-gas mixture into a cylinder and compressing it with a piston.
• Cylinder deactivation which turns off certain cylinders when there is no need in much power.
• Turbocharging that keeps the exhaust or wasted energy and uses it to spin the turbine.
• Direct fuel injection which provides better mist of fuel than indirect injection which burns without extra waste.
