Hybrid Electric Cars

Hybrid electric cars are vehicles which have the combination of a conventional and established propulsion system and a rechargeable energy storage system to attain better fuel economy compared to a conventional gasoline powered vehicle. It further includes a propulsion system in addition to the electric motors, not a disadvantage by range from charging vehicle like that of an electric car.

Recently produced hybrid electric cars have prolonged charge on their batteries by catching kinetic energy through the regenerative braking system and some of the hybrid electric cars utilizes the internal combustion engine to produce electricity by spinning an electrical motor generator to either have the purpose of recharging the battery or in other cases, directly feed the power to an electric motor that operates the vehicle.

Most of these hybrid electric cars reduce the idle emissions by putting off the internal combustion engine at idle mode and have it restarted when needed. Engines of these electric cars are smaller compared to a non-hybrid petroleum powered vehicle and can run on various ranges of speeds and can provide more efficiency.

These hybrid electric cars had been widely available for public in the late of 1990s with the launching of Toyota Prius and Honda Insight. They are perceived by most of the auto manufacturers as a major segment of the future innovation in the automotive market.

Fuel sources and engines of hybrid electric cars include the gasoline engine and are most widely used in hybrid electric cars design. This type of engine will be likely more dominant in the near future. Although, the primary fuel is the petroleum derived gasoline, it is still possible to mix in the varied levels of ethanol derived from renewable sources of energy. Most of the modern hybrid electric cars can commonly use up to 15% of bioethanol. Manufacturers are then flexible to move to other alternative fuel engines, but somehow, no plans are set in the present.

Diesel hybrid electric cars utilize a diesel engine to generate power. Diesel have the advantages in delivering constant power for longer periods of time and suffer less wear during its operation at higher efficiency. The high torque property of the diesel engine combined with the hybrid electric technology may considerably offer improved mileage. Almost all of the diesel electric cars can use 100% pure biodiesel, thus, they can use petroleum, but not as a fuel but just for lubrication purposes only.

Diesel hybrid electric cars particularly buses have began to commercialize. As of 2008, there is still no currently available light duty diesel hybrid electric cars specifically passenger cars, even though there are prototypes of it that exists. Peugeot is then expected to manufacture its diesel electric cars counterpart for its 308 later this year 2008 in the European market.

PSA Peugeot CitroŽn had launched two of its demonstrator vehicles and featuring a hybrid electric drive train, the CitroŽn C4 Hybride HDi, Peugeot 307, and CitroŽn C-Cactus. Also, Volkswagen manufactured prototypes of diesel hybrid electric cars that can attain 2L per 100km fuel economy. General Motors had been testing their Opel Astra Diesel Hybrid. There had been no fixed dates as to when these vehicles will be starting its mass production. On the other hand, Robert Bosch GmbH was supplying diesel hybrid electric technology to different car manufacturers including the Peugeot 308.

As fas as the mass production for hybrid electric cars is concerned, it is mostly appeared in mass transit vehicle buses. FedEx had began deploying small fleets of hybrid electric diesel delivery trucks along with Iveco in Europe and Eaton Corp in the USA. Since October 2007, this company, FedEx had been operating more than 100 diesel hybrid electric vehicles in North America, Europe and Asia.
