A year ago at the Geneva Motor Show, Bentley took its first tentative step toward being ever-so-slightly greener with the introduction of the Continental Supersports coupe. The Supersports was a lightweight, higher-powered version of the Continental GT that was the first in the range to offer flex-fuel E85 compatibility. After several months on the market now, Bentley is adding a convertible version of the Supersports next week in Geneva. Bentley has also announced that, as of this June, all Continental... Read More

Did you know that you can run you car on a water burning fuel! Sounds science fiction but its true! The current technology allows you to run your car on water! Click here to find out more! It is the talk of the town in many states. Can you run your car on tap water? I mean tap water is such a seemingly "worthless" household item. Use it to wash my car, maybe. But to power my car with water seems rather far-fetched or is it? Reports from various states have pointed this "run car on... Read More

Plug-in hybrid cars combine the benefits of pure electric cars and hybrid cars. Like electric cars, they plug into the electric grid and can be powered by the stored electricity alone. Like hybrid cars, they have engines that enable greater driving range and battery recharging. What is a Plug-in Hybrid Car? Plug-in hybrid cars can be charged with electricity like pure electric cars and run under engine power like hybrid cars. The combination offers increased driving range with potentially large... Read More

Light-duty natural gas cars work much like gasoline-powered vehicles with spark-ignited engines. This schematic shows basic CNG fuel system components. 2008 Honda Civic GX Natural Gas Car CNG enters the car through the natural gas fill valve (A) and flows into high-pressure cylinders (B). When the engine requires natural gas, the gas leaves the cylinders and passes through the master manual shut-off valve (C). The gas travels through the high-pressure fuel line (D) and enters the engine compartment.... Read More

Compressed natural gas (CNG) and liquefied natural gas (LNG) are considered alternative fuels under the Energy Policy Act of 1992. Natural gas cars are either fueled exclusively with CNG or LNG  or are capable of natural gas and gasoline fueling.   What is a natural gas car? Dedicated natural gas cars are designed to run only on natural gas; bi-fuel natural gas cars have two separate fueling systems that enable the vehicle to use either natural gas or a conventional fuel (gasoline or diesel).... Read More

Propane, also known as liquefied petroleum gas or LPG, is considered an alternative fuel under the Energy Policy Act of 1992. There are more than 270,000 on-road propane cars in the United States and more than 10 million worldwide. Many are used in fleets, including light- and heavy-duty trucks, buses, taxicabs, police cars, and rental and delivery cars. The availability of new light-duty original equipment manufacturer propane cars has declined in recent years. However, certified installers can... Read More

For most medium- and heavy-duty applications, diesel vehicles are the norm (in contrast to light-duty applications, where gasoline vehicles dominate). Although medium- and heavy-duty diesel vehicles are not technically "alternative fuel vehicles," they can use alternative fuel and benefit from strategies that reduce fuel use and emissions. Medium-Duty Vehicles Medium-duty diesel vehicles serve a wide array of applications. With gross vehicle weight ratings (GVWR) of about 8,500 to 26,000... Read More

Light-duty vehicles have less than an 8,500-lb gross vehicle weight rating (GVWR). They include sedans, pickup trucks, high-performance sports cars, sport-utility vehicles, and passenger vans. Gasoline-powered vehicles dominate this class in the United States. However, more light-duty diesel vehicles are becoming available as state-of-the-art "clean diesel" technologies enable them to meet the same stringent emissions regulations as gasoline vehicles. The high fuel economy of light-duty... Read More

Volkwagen Jetta TDI – The Most Fuel Efficient Diesel Car Advanced diesel vehicles using EPA-mandated ultra-low sulfur diesel (ULSD) fuel are among the most fuel-efficient vehicles available today. Collaborative R&D between DOE, industry and the national laboratories has resulted in improved engine efficiency and very low emissions. Collaboration with the U.S. Environmental Protection Agency, industry, and national laboratories under the DOE Diesel Emission Control Sulfur Effects (DECSE)... Read More

Sold by all U.S. vehicle manufacturers, flex fuel cars are capable of operating on gasoline, E85 (85% ethanol, 15% gasoline), or a mixture of both. There are more than 6 million flex fuel cars on U.S. roads today, but many flex fuel cars owners don’t know their vehicle is one. What is a Flex Fuel Vehicle? flex fuel cars are capable of operating on gasoline, E85 (85% ethanol, 15% gasoline), or a mixture of both. flex fuel cars qualify as alternative fuel cars under the Energy Policy Act of... Read More
