Today people are not concerned about environmental issues. The campaign for global warming has made it clear that the planet can retaliate due to mankind's abuse. Science and technology have greatly developed over the years at the expense of the earth's natural resources and environment. Pollution is one of the major causes and with the continuing growth of the population; scientists are finding ways to save what is left.

Apart from environmental factors pollution can also greatly affect the health of the general public especially in the suburbs. Gas prices have also soared. Due to this people have turned to hybrid vehicles instead of the conventional four-door and SUV. Hybrid technology has developed greatly in the recent years.

The Hybrid

Hybrid vehicles work primarily by an electric motor powered by a rechargeable battery. It is coupled with an internal combustion engine to help it at high speeds. It also has the ability to recapture energy made from braking.

Full hybrid vehicles have computers on board to determine the best way to conserve energy and fuel. They can move using their batteries alone for power. When the vehicle is idling or coasting the engine is turned off. They can also use a combination of these power sources for efficiency. They split power paths that enable them to switch between using mechanical or electrical power.

Apart from using a different power source these vehicles can also use different fuels. They can use a mixture of petroleum and biofuels. Other hybrid vehicles can also be recharged through a standard electric wall socket.

Hybrid vehicles save on gas which leads to less greenhouse emissions. They have also been noted to reduce noise emissions. The use of electrical power decreases the wear on the engine. Contrary to what some believe their batteries are not hazardous materials and can be recycled. These batteries are also durable and rarely need replacement.

Hybrids are perfect for the suburbs. In this area you don't really need horsepower but gas mileage. Hybrids can recharge themselves when braking and only use the needed power in idle periods such as traffic. In reality you don't really need a huge amount of horsepower when driving around in the city traffic.

These vehicles also contribute to the general health of the public. Emissions don't only contribute to the greenhouse effect but also to respiratory diseases. For now, hybrid vehicles are expensive. The technology is still fairly new in the fuel dependent automobile industry.

Many of us don't really think much about our surroundings. In fact most of us would buy a luxury Sport Utility vehicle in a heartbeat if we could. Although there have been incessant campaigns in global warming many of us don't really pay attention to pollution emitting out of our car's exhaust pipe's. That was until gas prices started to soar and people were desperate for alternatives. Hybrid technology was new and misunderstood in the past. Visions of weird boxes on wheels came to mind. That was until the Toyota Prius came out in 1997.

The first hybrid car did not look out of this world or too space age for the common person's taste. It was just a conventional looking car that saved on gas. The hybrid technology spread slowly. Sales from the Prius and Insight were moderate. Nonetheless, the public supported the technology which led to further improvements. The Ford Escape hybrid filled the gap between looking good and doing well. It had style and practicality which became the cue for luxury hybrid cars to add to the market.

Although hybrid cars are a good choice for today, is it really worth spending a lot of money to save the environment? And how do you know which to buy amid the slew of eye candy hybrids?

Why and what hybrid to buy

Hybrids run on electric power though their motors. These motors also serve as generators that recharge batteries on board to power them for mileage. This enables the vehicle to use less fuel which leads to lower costs and reduced emissions. The internal combustion engine serves as a back up for more power at high speeds. A computer determines which and how much power will be used from the motor and the engine.

Hybrids recharge through regenerative breaking. They are perfect for driving in the city where stop and go driving is common. In the city drivers don't really need a lot of horsepower.

Other motor companies have made hybrids to add to their credentials. If you really want to be practical a compact four door sedan will do well for you instead of a hybrid SUV that cost twice as much. Luxury hybrids may do well in the long run by saving gas but spending more than $60,000 on a practical car defeats its purpose.

If you want to go green, go simple. In reality you don't need to drive a 200 horsepower vehicle.

Vehicles are important tools for transportation. Unfortunately they have harmful effects on the environment, health and wallets of the people. The continuing rise of gas prices and campaigns on global warning make you want to ditch that SUV for a bike. Fortunately other power sources and fuels are being developed to serve as an alternative. Hybrid vehicles are a compromise between using a car and caring for the environment.

There are different types of hybrid vehicles. Each of them differs by what type of power source they are using. Although these cars may not run as fast as a conventional car on the highway, it's convenient for the suburban environment where traffic is normal.

Plug and play

Hybrid vehicles can be charged by using an external source. Although this was one of the earlier developments which made it one step ahead of conventional cars, it's not as practical as it sounds. Due to this plug-in hybrids were created. These vehicles have batteries which can be recharged through a standard wall socket.

Important developments weren't made until 2002. Plug-in hybrids were not sold commercially until 2003. The vehicles power source still operates the same way as a conventional hybrid but modified for the owner to be able to recharge it like an iPod.

These vehicles operate in 4 different modes. Charge depleting mode relies exclusively on electricity until the battery reaches a predetermined level. There is a predetermined level that automatically signals the car to stop running on electric power and switch to charge sustaining mode. The variation of this is the blended mode used by cars that cannot run at high speeds by using electric power alone and uses the diesel engine for help.

In charge sustaining mode it uses the combination of a diesel engine and its battery so that the vehicle will not exceed the predetermined level. This type of mode is used by conventional hybrids. In mixed, all of the modes mentioned are used and the vehicle switches between the four during the trip.

The disadvantage of the hybrid is the battery. Battery packs are expensive and can be large and heavy. Customers without garages will not be ale to recharge their cars because of the absence of an electric wall socket. Although emissions are reduced by the car it will be replaced by the plants that produce electricity. On the positive side pollution will be taken away from cities and the suburbs where it has a harmful effect on the health of the general public.

Sport utility vehicles have been famous for their features and looks. When they came out, the vehicle became a favorite among celebrities and people were more than willing to buy it. Unfortunately a lot of people are also against it for its size and fuel consumption. It does have the power but at the expense of your wallet and environmental conscience (that is if you have one). Fortunately Ford has decided to follow in the Footsteps of the Toyota Prius. The first ever hybrid car sold on the market.

Due to soaring gas prices, the new technology was supported and Toyota dominated the hybrid automobile market. Ford made a hybrid version of their Ford Escape which started the SUV hybrid. After the successful launch of the Ford Escape, Toyota decided to jump on the bandwagon and created the Highlander Hybrid SUV.

A step up from the Prius

Although it is not clear if Toyota earned a profit from the Prius, they still continued to develop and manufacture hybrids. Sales didn't pick up until 2004 and when other motor companies decided to make hybrids of their own it was clear that the technology was worth investing in. Toyota then decided to make a hybrid version of their commercially successful Highlander.

The highlander, like other Toyota's creations has the hybrid synergy system but with a new power train to be able to sustain load carrying requirements of the SUV. It is a formidable propulsion management system in hybrid technology that was also used in the Ford Escape. It has a 3.3 liter V6 engine and two permanent magnet electric motors with a peak power of 270 horsepower (combination of gas engine and electric motor).

The highlander comes in front wheel and four wheel drive. It has daytime running lights, power windows, tilt steering wheel, door locks, cruise control, and a radio and CD sound system with six speakers. It also has a navigational system that monitors on which and how much power it will use from the gas engine and the electric motor. The highlander is also an example of a full hybrid and can run off the electric motor alone.

The highlander, like other Toyota hybrids has regenerative braking, continuous variable transmission, anti-lock system, and Vehicle Dynamics Integrated System. It has the advanced airbag system for the driver and the passengers. The highlander can be expensive but it will be beneficial in the long run.

Hybrid technology has come a long way since Toyota released the Prius. Sales substantially picked up in the market prompting other automobile companies to make their own hybrids. Following in the footsteps of Toyota in 1997 Honda made its own hybrid. The Honda Insight was a moderate success. Although it was a fuel efficient car it had different technology under the hood. The hybrid technology was new at that time and the public perceived the Insight to look to odd to be driven around the city.

Honda then turned to one of its famous compact sedans. The Honda Civic was released in a hybrid version in 2003. The design was pretty much the same with the conventional Honda Civic incorporated with Honda's own hybrid technology.

Honda Civic Hybrid

The first generation Honda Civic hybrid came out in 2003. It operates with a different hybrid technology compared to the Toyota Prius which is the basic template for all hybrids. Instead of the hybrid synergy system, the Honda Civic hybrid uses an Integrated Motor Assist system that was also used in the Insight.

The first generation was produced from 2003 to 2005. It has a 1.3 liter lean burn internal combustion engine with Honda's VTEC cylinder cut-off system. This allows 3 cylinders to stop operating while decelerating which reduces friction losses. This in turn creates a more effective way of regenerating energy. It has a 15 kW permanent magnet motor which also serves a generator for recharging the batteries. It also has a 120 V nickel metal hydride battery, 5 speed manual transmission, regenerative braking, electric power steering, and low rolling resistance tires.

The second generation was also equipped with the same thing with a few changes. A high profile camshaft was added, fourth generation Integrated Motor Assist and third stage VTEC and Variable Cylinder

Management replaced the previous ones. It has a satellite-linked navigation system and an audio system that supports mp3 and WMA. It also comes in with an average fuel consumption regulator. An idle stop feature automatically shuts off the engine in idle periods.

The second generation was also an improvement from the first one which used lean burn engine.

Honda has stopped producing Civic hybrids to replace them with smaller and affordable types to compete with Toyota. Nonetheless previous the second generation proved to be a worthy competitor to the Prius. Although they may differ in terms of technology, fuel efficiency was still attained.

There are many hybrid vehicles on the market today. Unfortunately due to the unique technology they don't come cheap, developments and experiments with high powered engines made them more expensive. The perks provided by luxury cars come at a price. If being environmental friendly is this heavy on the wallet then why buy?

Hybrid vehicles may be an instant shock to the wallet but they are beneficial in the long run. Apart from SUVs and luxury vehicles there are also compact four doors that may provide an alternative for the average Joe. Following the success of the Camry, Toyota has decided to give the model a fresh new trim by turning it into a hybrid. Using Toyota's latest hybrid technology, the Camry may provide to be an alternative to expensive hybrids.

Camry facelift

The original Camry didn't give its owner many problems. It's priced right, big and powerful enough for the average Joe. With soaring gas prices, more people are willing to support and pay for hybrid technology. This prompted Toyota to hybridize its Camry to give customers a break from expensive sedans and Sports Utility vehicle hybrids.

Like other hybrids today, the Camry is equipped with a gasoline engine and electric motor combo. It has a 192 horsepower and runs at 38 miles per gallon. It still has the same accessories as of the previous Camry like alloy wheels, daytime headlights, power heated mirrors, six CD changer on the dashboard, eight way power and eight stereo speakers. The CD changer is compatible with a mp3.

It's still equipped with standard safety features such as airbags in the front, on the seat mounts for side impact, at the side curtain, and for the driver's knee.

The main difference is additional features. The hybrid Camry has a push button start system, Smart Entry keyless locking, power door locks, anti-lock out windows and the air-conditioning relies on the electric motor. It also has anti-lock breaking system and Toyota's Vehicle Dynamics Integrated System. The latter has traction and stability control with other electronic devices for vehicle control.

The Camry may not look as stylish as other luxury sedans and SUVs. But if you are looking for an affordable car that has been tried and tested this would be a good car for you. You don't really need lots of horsepower for city driving. The Camry provides the best of both worlds while still being able to be accessible for the average Joe.
