Conversely, short bursts of power can also be absorbed by the SpeedStart generator to recharge the battery during vehicle decelerations. The concept ensures long term energy storage for delivering short bursts of power to the VTES supercharger during vehicle accelerations and to the SpeedStart stop-start device during engine re-starts.

Ford displays prototype Carbon Fiber Reinforced Plastic hood

Green Car Congress

There are two ways to reduce energy use in vehicles: improving the conversion efficiency of fuels to motion and reducing the amount of work that powertrains need to do. Dow Automotive Systems and Ford will focus on establishing an economical source of automotive-grade carbon fiber, as well as high-volume manufacturing methods.

Turbocharging and downsizing can also yield fuel consumption reductions. Downsizing is an important strategy applicable in combination with technologies that increase engine torque, such as turbocharging or supercharging. Part of the gain from advanced-level CI diesel engines comes from downsizing.
