New passenger vehicles are projected to have an average of about 40 MPG in 2025 due to the existing fuel economy and GHG standards. Learn More.

There are many ways to achieve 100 MPGe. Here’s one example: almost half of all cars and trucks are plug-in hybrid electric vehicles that run on both gasoline and electricity while the rest are hybrid vehicles that just operate on gasoline. The use of strong lightweight materials cuts the weight of new vehicles in half and both wind and road resistance are significantly reduced through improved aerodynamics and better tires.

Wow! That’s a high fuel economy. We don’t know of any car that could approach this level without driving on frictionless roads or otherwise defying the laws of physics. Do you want to select a lower MPG or give this one a try?

Enter your new MPGe:

You selected a high percentage of diesel fuel. When choosing average mpg, keep in mind that cars and trucks running on diesel are usually more fuel efficient than comparable gasoline vehicles.

Keep in mind, hydrogen-powered fuel cell vehicles are very fuel efficient achieving about 50 MPGe or more today. This will likely improve over time as the technology improves and more models enter the market.

Keep in mind, electric vehicles and plug-in hybrid electric vehicles are very fuel efficient. Many electric vehicle models are achieving 100 MPGe or more today.
