Fuel efficiency is dependent on many parameters of a vehicle, including its engine parameters, aerodynamic drag, weight, and rolling resistance. There have been advances in all areas of vehicle design in recent decades.
Hybrid vehicles use two or more power sources for propulsion. In many designs, a small combustion engine is combined with electric motors. Kinetic energy which would otherwise be lost to heat during braking is recaptured as electrical power to improve fuel efficiency.

Famous quotes containing the words design and/or vehicle:
“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (18031882)
“Its idea of production value is spending a million dollars dressing up a story that any good writer would throw away. Its vision of the rewarding movie is a vehicle for some glamour-puss with two expressions and eighteen changes of costume, or for some male idol of the muddled millions with a permanent hangover, six worn-out acting tricks, the build of a lifeguard, and the mentality of a chicken-strangler.”
—Raymond Chandler (18881959)
