Dodge Durango Hybrid Car Review

The history of Dodge is one of strange disappointments and then some major come backs that have launched the company into the top lines of the industry. During the 1980's Dodge rolled out a line of seemingly well built yet inexpensive automobiles and the public began snapping them up. Well it was not long before the bottom started falling out this whole time period. The cars were anything but well made and the problems started happening. The auto maker had went with a cost cutting measure that turned them upside down and nearly drove them bankrupt. They had decided to run a deal where all the new Dodge company models would feature foreign made motors because there was a large price break. Well the motors turned out to be nothing more then junk and they ended up having a huge down turn in sales as nothing was selling amid these disappointments. Beginning in the early 1990's Dodge decided to get back to their grass roots. They introduced the highly popular Ram truck with a new design. Today they are back where they should be and making waves by once again offering the Hemi motor in many of their vehicles.

The Dodge Durango is one such vehicle. The five liter Hemi V8 has been added to the new Dodge Durango and this has made the public very happy. There has been a definite problem though. Thanks to the ever increasing price of gas, the V8 is no longer a popular motor and Hemi does not offer anything less. To answer that issue the Dodge company has decided to roll out the hybrid version of the Dodge Durango, complete with the Hemi V8 motor for the 2008 model year. This has the entire industry in fits as this will be one of the biggest things since the invention of the hybrid. In most cases the hybrids that are created require all new motors. With the new Durango the same Hemi V8 that is now available will have the new electric assist motors attached to improve the gas mileage and the emissions of this widely popular model.

The Durango will feature the new Advanced Hybrid System 2, which is a shared system that was devised in partnership with GM. This system will make the Durango one of the first full hybrid full size SUVs in the entire world. The Dodge company has stated that they expect the new system to increase the Durango's mpg rating to at least thirty miles per gallon in the city, which is practically unheard of for a vehicle that size.

Hybrid Cars How They Operate

There are two main types of hybrid cars: series hybrid cars and parallel hybrid cars.

Parallel hybrid cars work by using a combination of a traditional gas engine and a high output electric motor. The different elements of the engine start working at higher or lower levels of output are required. If the car is being driven carefully and accelerating at a reasonable level the electric motor will work on its own until a greater output is needed at a higher speed. Then the small high performances, in terms of fuel economy that is, gas engine takes over. This is a seamless almost unnoticeable process with a smooth transition of control from electric to gas power. Hot Car Forum

As the acceleration is powered by the electric motor the gas engine can be much smaller and more economical. There is no need for a great deal of energy, merely enough to keep the car at a steady speed, or to move the car from a mid range, around 40 mph to a higher speed. This requires a lot less energy than the initial movement from a standstill and consequently can be achieved with a lower level of power.

The parallel system of using both the gas engine and electric motor for hybrid cars means that there is less loss of power as when the car is traveling at higher speeds. As the energy is not required to go through the batteries and electric motor before providing power to the car. When traveling in this mode there is no need for the electric motor to operate and this also allows it to be recharged by the gas engine as the vehicle is traveling along. All ready for when the hybrid car slows and switches back to the electric motor.

Series Hybrid Cars: a series design works by powering the vehicle through an electric motor. The batteries supply the power to the motor. As the power arrives at the motor through the battery, series hybrid cars need a substantially larger reserve of power and consequentially a greater amount of batteries need to be carried in the car.

The motor only uses the exact amount of power required for the task in hand. If you spend hours in a traffic jam, you may get a little hot under the collar but your car will not be overheating. An electric motor does not need to tick over or idle when sitting in a jam; it will simply start turning when you start moving. When driving hybrid cars there will be no power (although maybe a little hair) lost even in the most extreme of gridlocks. As the motor will not be working when the vehicle is still, there is no need for the batteries to be recharged until power is again being lost when the car starts to move forward.

The large battery supply that is required for series hybrid cars is kept supplied with energy by a generator that runs from the main gas power unit. This only needs to operate when the batteries are in need of extra power so for much of urban driving there is no need for the motor to operate as only low levels of power are required. This allows the hybrid cars engine to run without emissions for city driving, especially if some higher powered driving, as for highways or main routes is done, and the consequent loss of power means that the hybrid cars batteries are brought upon to their full power supply by the gas motor when out of the urban environment.

There are advantages to both systems, but overall the parallel system is the most flexible for hybrid cars as it allows for the option of either power source to be transferred directly to drive the car without going through another separate means of transmission to the wheels.
