Hybrid cars, the solution for emissions


Ford, Toyota, Nissan, General Motors, Audi, Volkswagen, Chevrolet… there are so many ecological car parcels currently available on the market. These are hybrid cars that should solve two problems: counter the expensive gasoline and reduce pollution.

It is believed that with the spread of ecological cars, there would be a drastic reduction of harmful emissions related to mobility. This will help to combat the phenomenon of global warming, but also that of expensive gasoline given that the eco car guarantee low consumption.

The automotive landscape records two trends. On the one hand, companies are engaging in a competition to see who produces thegreener car and on the other hand, the trend of acceptance by the users of these cars is slowly growing. Users are increasingly interested in the cars they guarantee low emissions and reduced consumption. During 2011, Toyota launched its “Toyota Hybrid” and Nissan secured a large share of the market with its Leaf and the Altima brand with its green vehicles. Also last year we saw the debut of the company's Volt Chevvy General Motors and Ford launched his Escape Hynrid.

In past years, others hybrid vehicles were launched on the market. Let's make a brief history with the prominent models from 2006 to today.
In 2006, the Mercury Mariner Hybrid was released.
In 2007 the Toyota Camry Hybrid debuted
In 2008, the Chevrolet Tahoe Hybrid hit the market
In 2009 Volkswagen launched its Jetta TDI
In 2010, the Audi A3 TDI was introduced
2011 was the year of the Nissan Leaf

2012 will be the launch year of the Honda Civic natural gas, already awarded the title of green car of the year. More importantly, 2012 will be the year in which incentive plans for the purchase of hybrid cars will be set up in many EU countries. Currently it seems the best bet to reduce CO2 emissions related to mobility, is given precisely by hybrid vehicles. The hybrid cars they are equipped with two different power sources for the motor. One motor is the electric one, powered by the battery. The second engine is the more conventional one, powered by petrol or diesel.

The main advantage of the hybrid cars lies in the torque of the motors. The engines are complementary to each other, thus increasing the overall efficiency of the car. The electric motor is completely offline when the car whizzes at high speeds, while when thehybrid car proceeds at high speed, both engines are operated thus reducing the harmful emissions released into the atmosphere with the exhaust gases.

The safety of the hybrid cars but this fear has been overcome thanks to various researches, including the study of the Loss Data Institute specialized on motorway issues. According to this study, the additional weight of electrical plugins would make the hybrid cars safer and more stable, therefore less prone to accidents.

What are the difficulties that hinder the spread of hybrid cars? The speech is very similar to that made for the diffusion difficulty of electric cars. First of all, the slow spread of these cars is to be linked to the trend with which the car manufacturers have approached the sector. In 2006 there was a hint of interest but only in 2011 the interest was consolidated.

Other issues are environmental: a study of United Nations Environment Program (UNEP) highlighted the lack of an adequate recycling plan. Therefore metallic materials such as neodymium, dysprosium, lanthanum ... used for the production of hybrid cars, threaten the environment and therefore, the very production of hybrid cars.
