Read the chapter summary below:

■ Advancements in electronics and computer technology have enabled many on-vehicle security features, including vehicle tracking systems and night vision systems.

■ The use of servo motors in an electric brake caliper eliminates the need for the brake system hydraulic components.

■ A dash-mounted switch energizes the electric parking brake servo motor to mechanically apply the rear brake.

■ Kinetic energy recovery systems can capture kinetic energy generated during vehicle braking and store the energy to assist in vehicle acceleration.

■ Alternate power sources are other methods of producing energy (other than from gasoline and diesel oil) to propel a motor vehicle.

■ Electric vehicles use an electric motor and storage batteries to power the automobile and reduce air pollution from burning fossil fuels.

■ A flywheel generator drive system is a direct electric wheel drive design that eliminates the need for friction brake pads and large rotors.

■ A solar vehicle uses solar panels to generate electricity for propulsion.

■ Hydrogen burns with no harmful emissions—water vapor is the only by-product of combustion.

■ A fuel cell combines hydrogen and oxygen to produce electrical energy.

■ A flexible-fuel vehicle (FFV) is designed to operate on different types of fuel.

■ Plant fuel research has led to the development of biodiesel fuel, ethanol, and synthetic motor oil.

■ Vehicle curb weight reduction is the most important factor in further improving fuel economy.

■ Since human progress is increasing exponentially, we should see even more rapid technical progress in the future.
