Hybrid Car Advantages for a 21st Century RideHybrid car advantages - a brief guideSo what's so great about hybrid cars? What are the hybrid car advantages? Are they really that much greener and cleaner? Can they save you any real money on fuel?
Booming hybrids!
Hybrids have been around for a few years now and sales are booming in Europe. In the US, too, sales are accelerating, perhaps especially now Chrysler is dipping it's big toes in the water! Hybrids got off to a faster start in the US because here in Europe the diesel motor has been promoted as a way of acheiving fuel efficiency. Europe is now beginning to catch up. Here's a brief run down of some of the main hybrid car advantages - and a little about their limitations, too. Picture: for all the new hybrid car advantages, they won't cure traffic congestion - but they do help reduce the resulting pollution. Hybrid car advantages - a brief guide: A hybrid car is simply a car which runs on more than one type of fuel. See Hybrid car definition for more details and some of the commoner hybrid car types. The commonest types run on both gasoline (petrol) and electricity. The elctricity is supplied by a sophisticated battery system. Some hybrids run on petrol and ethanol. Most hybrid cars run mainly on petrol. The petrol fuels an internal combustion engine in something like the traditional way. Some of the power from the petrol motor also charges up the battery when possible during normal operation. The battery then powers some of the car's motion to enable greater fuel economy. That's a very basic outline - most hybrids incorporate lots of high-tech methods for further improving efficiency and pollution control. First, the commonest types of hybrid car:The most common type of hybrid - known as a "parallel" hybrid - has the transmission powered by both the electric engine and the internal combustion engine. Some of these - the "full" hybrids - can run on just battery, just petrol or a combination of both. the Toyota Prius is an example of a full hybrid of the parallel type. The distance run on just battery is usually very limited, however. There are also "series" hybrids (example: Honda Insight) where the electric part of the motor merely serves to complement and augment the gas engine. With this type of engine real savings in fuel use can be made (a Honda Civic hybrid, for example, will achieve as much as 51 mpg) but you cannot travel on battery power alone. The gas portion of the car powers a generator and the generator then supplies electricity to run the motor. Both types improve the efficiency of the car, which is why hybrids are becoming increasingly popular.
Plug-insPHEVs are plug-in hybrids. This means that you simply plug 'em in and charge 'em up, pretty much like any other rechargeable battery-driven appliance! People who love them claim that they are not only cleaner than standard cars but will actually get cleaner as they age! Why? because power stations (which supply the electricity that they run on) are becoming cleaner and greener year on year. They are not generally available as yet but conversion kits do exist and in the near future public service vehicles such as school buses may well be fuelled this way. The present generation of hybrids are not plug-in cars - the batteries are recharged by the brakes and when the petrol engine is in use. Flex-fuel vehiclesFlex-fuel hybrids are sure to be popular as they allow flexibility to use different fuel sources - ethanol, biodiesel and gasoline as required or as available. SUVs anyone?If you are a lover of SUVs (Sports Utilty Vehicles) the Ford Escape offers a chance to be a little bit greener. They currently cost 3000 dollars more than a conventional model but the pundits reckon you'll save almost twice that in fuel costs. Still, they only manage a measly 30 mpg which won't sound like a lot for anyone who wants to be seriously green. Still this is quite good compared to most SUVs!If you are a US citizen you may even qualify for a tax rebate for running a clean-fuel car. The Ford Escape has proved popular since its introduction in 2005 and Ford is set to expand production to meet demand. The new Chevy Tahoe hybrid is able to run on battery only at low speeds with light loads. It has a sophisticated two-mode operation and looks set to cut a dash in 2008. It has already won awards but has been derided by environmentalists for its paltry mpg ratings. There are lots of variations on the hybrid theme and for people who seriously want to convert to hybrid driving it's important to do your homework about the different types and models on offer. Companies involved in hybrid manufacture are offering new improved models and more and more manufacturers are jumping on the bandwagon. The first (and main) hybrid car advantage of note is that they are so much cleaner than petrol and diesel only models. Full hybrids can run on just electricity. They have state-of-the-art batteries and they recharge while the gas engine is being used and during braking. This means that when they are being driven on the battery, there are no significant emissions, which makes them very clean indeed. At least, it makes them very clean from the perspective of the average pedestrian or cyclist on the street. There are no noxious fumes coming out of the exhaust pipe to clog your windpipe or assault your nose! Some of the most efficient hybrids can manage on battery only during the stop-go conditions of urban traffic. The Toyota Prius leads the field for efficiency, so far. Of course, if they are being driven on petro-chemicals full hybrids are still polluting by emitting exhaust gases. However, they are considerably cleaner than most older cars as they offer excellent fuel combustion and filtering of exhaust fumes. Hybrid cars which are not "full hybrids" still deliver some real gains; petrol goes further and fuel economy is easily achieved by any careful motorist. If you are a hybrid car owner you will also substantially reduce the emissions from your car of carbon gases and nitrous oxides. Obviously, with all this fuel efficiency, hybrids are cheaper to run. This is one of the other main hybrid car advantages over conventional motors. However, they are more expensive to buy! Hybrid car advantages - a brief guide:
A while back there were reports that a Hummer SUV would be greener and more energy efficient over its lyfe-cycle than a Toyota Prius. A little scrutiny of the "science" of this claim revealed that, of course the Toyota was far more energy efficient. The claims were spurious, based upon dodgy data and assumptions. But can hybrid cars really claim to be greener - greener than the conventional alternatives?Now that they have established themselves a track record over the last few years, I think it's fair to say that they are. Why?
Over a lifetimes use they should give real fuel economy - even upto 60 miles per gallon and beyond. This figure is set to rise, too, for some of the newest hybrid models coming onto the market. Hybrid car batteries (of the Prius, for example) are completely re-cycleable. Toyota run a comprehensive battery re-cycling facility for their nickel-metal hydride batteries. They also claim never to have needed to replace a battery through wear and tear! The engines emit far fewer toxic gases than the equivalent diesel and petrol models. Diesels, for example are not offered for sale in big US cities like New York and states such as California. This is because of the cancer and smog-causing exhaust emissions. Hybrids are regarded as far less polluting. It is likely that the EU will follow the US and Japan and implement stronger anti-pollution guidelines, which should persuade more manufacturers to produce hybrids rather than diesels. Yes, hybrid cars are more expensive and costly (in environmental terms) to produce. But the future of personal transport should guarantee that the very real hybrid car advantages gradually win through. Of course, if you're still driving an older type of car, you should still get as much "life" out of it as possible before changing up to a hybrid. In environmental terms, there is nothing to be gained from junking cars prematurely!
