Hybrid Cars

For a car to be considered a hybrid, it must use two or more distinct power sources. The majority of hybrids combine internal combustion engines with an electric motor.

Hybrid Power Sources

  • Rechargeable energy storage systems (RESS)
  • Compressed air
  • Coal
  • Electricity
  • Compressed natural gas
  • Liquefied natural gas
  • Hydrogen
  • Liquid nitrogen
  • Petrol fuel
  • Diesel fuel
  • Waste heat from internal combustion

Hybrid Electric Vehicles and PHEVs

When discussing hybrid vehicles, most of the time you will be referring to hybrid electric vehicles (HEVs) which include the AHS2 made by Chevrolet, GMC, Cadillac and Saturn; the Toyota Prius; the Camry hybrid and the Honda Insight.

HEVs increase gas mileage and reduce carbon dioxide emissions.

There are also PHEVs, or Plug-in Hybrid Electric Vehicles, which are fuel-electric hybrids that can be connected to power supplies to avoid charging with the on-board internal combustion engine. An example of a PHEV is the Ford Escape hybrid model.c

Fuel Cells

Fuel cell hybrids are electric vehicles equipped with fuel cells, which is an alternative mode of power that uses hydrogen as fuel. An example of a fuel cell hybrid is the Ford Edge Hyseries Drive or the Honda FCX.

Hybrid Emissions

One of the major reasons to have a hybrid vehicle is for environmentally-friendly purposes. Hybrids get close to or are lower than the recommended emission levels set by the Environmental Protection Agency. While recommended levels for passenger vehicles are around 5.5 metric tons of carbon dioxide, most hybrid vehicles produce 4.1 metric tons or less.c
