2/133D-Printed Classic Cobra
The 3D-printed Shelby Cobra was on display during Sustainable Transportation Day. The car was printed using thermoplastic resin and carbon fiber material by the Big Area Additive Manufacturing Machine at Oak Ridge National Laboratory and features a motor propelled by energy-efficient wide bandgap power electronics.

3/13Chevrolet Volt Slashing Carbon Emissions
The Chevrolet Volt is one of several plug-in electric vehicles on the market today, which play a key role in the country's transportation future. Switching to a mix of plug-in electric vehicles could reduce petroleum use by more than 40 percent and greenhouse gas emissions by more than 30 percent.

4/13Charging Forward with Electric Vehicles
As part of the EV Everywhere Grand Challenge, the Energy Department is working to lower the cost of plug-in electric vehicles like the Chevrolet Volt so they are as affordable for the average American family as gasoline-powered vehicles within the next 10 years.

6/13Fueling Up with Hydrogen
Fuel cell electric vehicles like the Hyundai Tucson run on hydrogen gas rather than gasoline and have the potential to significantly reduce our nation’s dependence on foreign oil.

7/13Fuel Cell Cars Hitting the Road
Fuel cell vehicles like the Toyota Mirai are more available to consumers than ever before. These cars can be driven more than 300 miles on one tank of hydrogen and refueling takes less than five minutes.

10/13Cleaner Cars
Fuel cell vehicles like the Hyundai Tucson are more efficient than conventional internal combustion engine vehicles and produce no harmful tailpipe exhaust--their only emission is water.

13/13A Winning (and Sustainable) Score
Using real race engine data, the Green Racing simulator calculates the amount of petroleum fuel consumed for both E85 and race fuel, and highlights the “green” scores for driving based on how much petroleum the driver saves using the hybrid system.
