Diesel Passenger Vehicles Both diesel cars and light trucks are receiving a lot of attention in the United States as a near term strategy to achieve fuel economy and climate change goals. The renewed interest in diesel as of late stems from its potential to improve passenger vehicle fuel economy. The best diesel passenger vehicles of today are more efficient on fuel than their gas counterparts, helping to reduce carbon emissions by 30 percent or more. There are some auto makers that are talking about re-introducing diesel into light duty markets as a solution for reducing global warming pollution from both cars and trucks. Another important reason is that the higher efficiency of diesels will provide a quick fix for manufacturers who are struggling to meet federal fuel economy standards for light trucks. Even if the efficiency benefits of diesel do yield real world improvements on the economy, the potential climate change benefits are modest. Even though diesel achieves more miles per gallon than gasoline, many are concerned about the impact that diesel passenger vehicles have on the economy. From time to time, the combustion in the engine can cause black emissions to spit from the exhaust, which is actually very bad for the economy. While gas is actually the worst, diesel is taking strides to improve engines and the impact on the economy. Diesel is getting more and more popular these days, as gas prices continue to rise and rise. Although diesel engines can have an impact on the economy, they are the way to go for those looking to conserve mileage. Diesel vehicles cost more than gas vehicles, although they will offer you more than you can expect. If you are looking for a quality ride, diesel is the way to go. (word count 291) PPPPP
