Distance measurement used for hybrid car's ability to rely on electric drive.

Short for Advanced Technology Partial Zero Emission Vehicles. Vehicles that meet California Air Resources Board's requirements for SULEV exhaust emissions, zero fuel evaporative emissions, 150,000-mile emissions durability and an extended emission systems warranty, are referred to as AT-PZEVs.

A battery-electric vehicles use an electric motor for power source. The electricity powering the motor is stored in a battery pack that must be recharged from an electric power source.

Similarly to "Fly-by-Wire" technology found in fighter planes, hybrid car "Drive-by-Wire" technology replaces mechanical connections with electrical connections to reduce weight and provide more sophisticated and reliable responsiveness.

The California Fuel Cell Partnership is a unique collaborative of auto manufacturers, energy companies, fuel cell technology companies, and government agencies to promote moving towards a sustainable energy future, increasing energy efficiency and reducing or eliminating greenhouse gas emissions.

Cleaner-burning gasoline is fuel that meets requirements established by the California Air Resources Board (ARB). All gasoline sold in California for use in motor vehicles must meet these requirements, which have been in effect since Spring 1996.

Also known as Stealth Mode. In full hybrid cars, electric-only mode allows the vehicle to drive at low speeds without the engine turning on.

An electric vehicle is a vehicle that uses electric motors for power source. Examples of EVs are metros, most trams, and for some trains.

A fuel cell vehicle is an electric vehicle that uses hydrogen fuel instead of a battery to produce electricity. There are no moving parts, as the fuel cell utilizes a catalyst to perform a chemical process that combines oxygen from the air with hydrogen fuel to produce electricity.

FFVs have a single fuel tank, fuel system, and engine, but are designed to run on any blend of gasoline and ethanol, up to 85 percent ethanol (a mixture known as E85 that can modestly reduce a vehicle’s global warming emissions such as carbon dioxide).

E85 fueling points are not readily available so you might have to do further research on fueling locations before purchasing.

Hybrid car with a 20 miles All Electric Range.

Hybrids combine an internal combustion engine with a battery and electric motor, offering the extended range and rapid refueling of a conventional vehicle but with the potential for much higher fuel economy. However, not all hybrids are created equal; some use the technology to increase acceleration rather than boost gas mileage.

One of the two EPA fuel economy tests, which consists driving routines, or schedules, performed in the laboratory.

A hybrid car refers to a vehicle that has two sources of power: gasoline and electricity. Today's hybrids combine a gasoline engine with one or more electric motors (and a traction battery pack).

There are two batteries on hybrid vehicles, the traction battery and the auxiliary 12-volt battery, which powers accessories and the car's computer.

In hybrid cars, engine refers to the gasoline combustion engine, not the electric motor.

Toyota's next generation hybrid powertrain, improving upon the Toyota Hybrid System in the original Prius.

There are several measurement standards for low-emission cars, including California Air Resources Board standards known as LEV II, Ultra Low Emission Vehicle (ULEV) and Super Ultra Low Emission Vehicle (SULEV) standards. There is also a Federal standard called Tier 2-Bin 3.

Neighborhood Electric Vehicle. EVs that operate below motorway speeds. Are not meant for highway use.

Honda is currently the only automaker offering passenger cars that run on compressed natural gas (CNG). CNG emits less air pollution and carbon dioxide than gasoline, but as with E85, CNG fueling stations are not widespread.
