DRIVING INNOVATION

Our fuel economy standards reduce energy
consumption. Every gallon of gas not
burned also reduces greenhouse gas
(GHG) emissions.

Our fuel economy standards enable
manufacturers to make a variety of
vehicles that meet consumer demand,
while requiring better average fuel
economy for their fleets as a whole.

Alternative fuels are often cheaper than
gasoline and diesel, and using these fuels
can help reduce the nation’s dependence
on foreign oil, along with the impact of
GHGs and other emissions that could
contribute to smog.

Our fuel economy standards provide incentives for manufacturers to build
alternative fuel vehicles. Vehicles that receive incentives include:
FLEXIBLE FUEL VEHICLES

can be filled up with a blend of
alternative fuels like ethanol or
biodiesel and traditional fuels
like gas or diesel.
HEVS, PLUG-IN HYBRID
ELECTRIC, AND ALLELECTRIC VEHICLES

use electricity either as their
primary fuel or to improve the
efficiency of conventionally
fueled engines.
FUEL CELL VEHICLES

can be fueled with pure
hydrogen gas stored in tanks
on the vehicle. These vehicles
emit no pollutants.

NHTSA SETS STANDARDS THAT REQUIRE MANUFACTURERS TO MAKE
THEIR VEHICLES MORE FUEL EFFICIENT WHILE CONTINUING TO MEET
OUR SAFETY STANDARDS. AND AS THE MARKET FOR ALTERNATIVE FUEL
VEHICLES CHANGES, NHTSA ENSURES THAT THESE VEHICLES ARE SAFE,
TOO. AS MANUFACTURERS MEET OUR STANDARDS, WE REDUCE AMERICA’S
DEPENDENCE ON OIL AND KEEP YOU AND YOUR FAMILY MOVING.

MORE INFORMATION.

COMPRESSED NATURAL
GAS VEHICLES

can run on compressed natural
gas, emitting 30-40% fewer GHG
emissions and 60-90% fewer smog
forming pollutants.
BIODIESEL

A blend of plant-based diesel
(biodiesel) with regular diesel fuel
can be used in many
diesel vehicles without any engine
modification.
