E85/ethanol--Essentially, alcohol created from vegetable matter and mixed with gasoline or used undiluted and straight up. E85 is the commercial name for the mix that is currently available at a growing number of gas stations around the country. It is 85 percent ethanol, 15 percent gasoline. GM and Ford both offer E85-compatible new cars and trucks designed to safely use this fuel (they can also run on regular gas when E85 is not available). The advantages of ethanol/E85 include lower emissions of unburned hydrocarbons, which form the precursors of smog, as well as the potential for a significant reduction in U.S. dependence on non-renewable, petroleum-based fuels such as gasoline. Also, most vehicles can be set up to operate on E85/ethanol at relatively low cost, and there is no loss of performance or power. Another nice thing about ethanol fuel is that it degrades quickly in water and therefore presents a much lower risk to the environment than an oil or gasoline spill. (See the National Ethanol Vehicle Coalition website to learn more about E85 and ethanol fuels.)

Biodiesel--Vegetable oil can cook your fries as well as power the vehicle that gets you to the drive-through. An interesting fact is that diesel engines were originally designed to run on vegetable oil, not petroleum-based diesel fuel. And they can run on vegetable oil just as well today and help keep the air cleaner and reduce our country's dependence on the oil cartels. Biodiesel is not the same as raw vegetable oil (though it can be run in diesel engines, too). It is, however, made from raw vegetable oil with its chief advantage over raw vegetable oil being that it can be used in any compression-ignition (diesel) engine with little or no modification necessary. (The use of raw vegetable oil in diesels requires pre-heaters and other fuel system upgrades.) Biodiesel is also less toxic than table salt and biodegrades as fast as sugar. (See the The National Biodiesel Board website for more information about biodiesel fuels.)

Electricity--Electric cars have been offered to the public as recently as the mid-1990s, when GM's EV-1 went on sale in California and a few other states. The idea of eliminating combustion engines entirely has always had tremendous appeal. However, engineers have not yet overcome the problems of limited range (typically less than 100 miles per charge), lengthy recharge times (several hours or overnight) and relatively poor performance compared with gas-powered or diesel vehicles. There are also environmental issues remaining to be dealt with, including the storage and recycling of hundreds of pounds of lead-acid battery packs per car and the source of the electricity used to charge those battery packs. In the U.S., a large portion of the electrical energy we use is generated by coal-fired utility plants, which produce millions of tons of carbon dioxide, a known greenhouse gas, every year. Until the problems with electric car battery packs and with the generation of electrical energy itself are resolved, it's not likely we'll see mass-produced electric cars. Solar-powered vehicles are also in their developmental infancy and unlikely to see production anytime soon.

Hydrogen/fuel cells--This technology uses a fuel cell to generate electricity, with liquid hydrogen as the fuel. The electricity produced by the catalytic reaction in the fuel cell can then be used to provide power to run electric motors, which propel the car. Unlike current electric cars, which have to be plugged in to recharge their batteries, a fuel cell vehicle creates its own electricity. Hydrogen is an abundant element, and the energy produced by a fuel cell free of harmful byproducts (water is the primary emission). However, practical problems remain to be overcome, the two biggest obstacles being the economical mass production of pure hydrogen and the second being the infrastructure (pipelines, refueling facilities, etc.) necessary to get the hydrogen to end users safely and efficiently. But several automakers, including General Motors and Honda, have prototype fuel cell vehicles under development, and we may see a breakthrough sometime during the next five or 10 years. (See the U.S. Department of Energy's Energy Efficiency and Renewable Energy for more information about fuel cells.)

Compressed Natural Gas--Like hybrid gas-electric vehicles, the use of compressed natural gas (CNG) is seen as a workable intermediate step between conventional gas-burning cars and a future form of propulsion that doesn't use gasoline at all (such as a fuel cell or electric car). The U.S. has large reserves of clean-burning CNG, and it is relatively easy to modify a conventional car engine to operate on this fuel. In addition, some of the necessary infrastructure (pipelines, etc.) to get CNG to end-users is already in place because CNG has long been in use for home heating purposes. GM, Ford and Chrysler have been building CNG-capable cars and trucks for several years and offering them for sale to both private individuals and municipal fleets. The cost per car is roughly $1,500-$4,000 more than an equivalent gas-only version of the same vehicle. (See California Energy Commission's website for for more information on CNG and CNG powered vehicles.)

While development of these future fuels continues, the automakers are also devoting much effort to continuous refinement of the century-old internal combustion engine. Today's gas engines run cleaner and more efficiently than ever before with no loss of power or performance. Technologies being used today to maximize every drop of gasoline include:

Variable displacement/displacement on demand--This system, which is used in several new GM and Chrysler vehicles, allows for some of the engine's cylinders to be shut down when they're not needed. Chrysler's 5.7-liter Hemi V8, for example, can operate in four-cylinder mode under light load conditions and automatically revert to all eight cylinders when the driver needs the power. This improves fuel economy by 10 percent or more and substantially lowers emissions of both smog-forming compounds and greenhouse gases like carbon dioxide.

Variable cam/valve timing--Similar to displacement in demand, this technology gives an engine two distinct personalities. At low speed/light throttle, the engine is quiet, docile and highly efficient. But as the driver demands more power, the cam/valve timing becomes more aggressive, delivering max power for as long as the driver wants it. Honda pioneered this technology with its VTEC system, which first appeared in the Acura NSX more than 15 years ago. Today, almost every major automaker uses some form of variable valve/cam timing to maximize efficiency and power without compromising either.

Fast-light catalysts--Catalytic converters are chemical exhaust scrubbers that convert harmful exhaust byproducts into harmless compounds such as water vapor. They've been in use since 1975 and have helped to dramatically lower the emissions output of the typical car or truck. (The average new car produces a mere fraction of the harmful emissions of a pre-controlled car.) However, to work at peak efficiency, a catalytic converter must be heated to very high temperatures very quickly. The problem is a cold engine is not very hot. And it is during the first few minutes of cold-start operation that a converter isn't especially good at chemically changing harmful emissions into innocuous compounds. The solution to this problem has been to snug the converter on today's cars as close to the engine as possible instead of downstream in the exhaust system, as was typical in the past. The result is faster "light off" for the converter and lower overall emissions.

My neighbor asked me if my lawnmower had v-tec, cause vtec is da bomb... *exact words from this tard*

I said, "It's a Lawnmower, not a fucking dragster"...* and walked away shaking my head...:owned:

He just stood there for a minute w/ a confused look on his face...

BTW... He has 3 hondas in his driveway...:rofl:
