Emission Benefits: Clean fuels have numerous properties which make them cleaner than other dirty fuels like gasoline or adulterated diesel mixtures. Usually these fuels release fewer hydrocarbons, and the hydrocarbons emitted are less toxic and less reactive. Emissions from electricity, natural gas, or alcohol-powered vehicles can be roughly about 90% lesser than in toxics and ozone-forming hydrocarbons than emissions from vehicles using dirty fuel.

Mileage Benefits: Apart from the emission benefits, the best thing that appeals the minds of the users is that the mileage difference is notable, which results in a lot of cost saving. Here, it is to be noted that there is a win-win situation. The better mileage advantage helps the companies increase their sale. Moreover, the customers get more than just cost effectiveness. European and Japanese automakers are about to invade the market with new clean-diesel models that catch much better mileage than the standard gasoline-burning model. Among the many contenders, Mercedes shall offer its SUVs -- M-Class, R-Class and GL-Class --with diesel engines. BMW aims to bring its popular turbo diesel engines to US models. And Nissan is coming with a diesel Maxima sedan. Volkswagen was an early pioneer in diesel in the US, but it will convert to new cleaner diesel technology in models starting 2008, which it dubs "Blue Motion." VW is betting its new TDI Jetta, which launches in February, will help stoke its US sales. (Business week May 04 2007)
This makes it clear that the model is not only gaining popularity for its air benefits but also finding high acceptance with the users, which is why the major players have shifted their focus to it. The concept of clean fuels actually came up to start with its clean atmosphere benefits, but eventually in the drive vehicle manufacturers opened their eyes to its selling points too. Today, they have been able to design innovative models resulting in cost effectiveness, speed, lower maintenance etc. for the users compared to the conventional petrol and diesel run trucks/cars.
It is to be noted that The 2007 Mercedes-Benz E320 BLUETEC is the first model in America to take advantage of the clean low-sulfer diesel (Autos, MSN)
Clean fueled transport vessels are in use and widespread usage in the near future is feasible. To facilitate the changeover, technologies must be polished so that the vehicles can be made to attain optimal performance and emissions features. Users must show their acceptability to better and newer vehicles and fuels, and industry as well as government must cooperate to ensure their availability. It would take a concerted endeavor by all segment s of the society, but a shift to clean fuels can be the most feasible way for cities to have clean air and for users to have a better performance along with cost cutting.
