In an effort to take advantage of the growing call for alternative fuels, General Motors is going to introduce a line of pickup trucks powered by natural gas. GM recently announced it will release bi-fuel versions of its Chevrolet Silverado and GMC Sierra trucks, Fox News reports.

The most important detail about the innovative vehicles is that they give motorists the chance to drive wherever they want without having to worry about finding a fueling station that offers natural gas. As their default setting, the trucks will be powered by the natural gas, but if that tank runs out the engine will switch to gasoline. Drivers can also choose to switch to gasoline by themselves if they hit a button.

"Range anxiety is very real," Joyce Mattman, director of GM commercial product and specialty vehicles, told the news source. "We worked with the Chevy Volt team on that, and saw the same issues."

There are a number of advantages to powering cars, especially trucks, with natural gas. Perhaps most importantly, natural gas is cheaper than gasoline. This is an especially perscient issue right now, given that gas prices could surpass $4 per gallon in the very near future.

According to Fox, trucks powered by natural gas are also more environmentally friendly. Specifically, vehicles that use the fuel produce about 25 percent fewer carbon emissions than standard cars. Additionally, because about 98 percent of natural gas is produced in the United States it can help reduce dependence on foreign oil.

Though natural gas-powered vehicles are still uncommon, there are other ways to save money on gas. One such way is buying a fuel-efficient car at New Jersey State Auto Auction. With a wide variety of makes and models there is something for everybody.
