. Gasoline and Diesel direct injection uses sophisticated electronic fuel-flow and air-flow controls, and precision injectors which inject the fuel directly into the cylinder and optimize the ideal mixture of air and fuel during combustion.

. Continuously Variable Transmission: Or CVT's don't have a gearbox with a set number of gears, instead they typically operate on a pulley configuration that allows an infinite number of engine/wheel speed ratios. This technology results in better engine speed matching, ideal "gear" selection and improved fuel efficiency.

. Hybrid Technology: by combining an internal combustion engine with an electrical motor and battery pack, most hybrids today can achieve improvements in fuel efficiency by using the electric motor to supplement engine power. Some hybrids can also operate exclusively using the electric motor at low speeds. Batteries do not require plugging in and are recharged by harnessing the energy from braking and from the engine.

Hybrids are ideal vehicles for individuals who travel predominantly in the city under stop and go conditions. Consumers can use this information to help them buy, drive and maintain their vehicles in ways that will conserve energy, preserve the environment, protect their health and save money.
