With the increase in gas prices around the nation, consumers are finding themselves wondering what fuel-efficient alternatives there are. In fact, more and more drivers are putting off getting to the gas pump and finding themselves stuck on the side of the road calling for emergency auto assistance. Gas-electric hybrids have received a large amount of attention recently, yet, diesel powered cars may be the answer.

Diesel cars have gained a lot of popularity around the world.  They account for approximately 50% of new cars in Europe; however, U.S. car shoppers have been slow to gain interest.

Even though fuel mileage levels can be around 40% higher with diesels than gas powered cars, diesels only account for 2% of the new cars in the U.S.

There is a whole new generation of diesels that are clean, quiet and much more powerful than in the past.  The 2007 Mercedes-Benz E320 Bluetec sedan will prove that this recent diesel technology can be luxurious in addition to giving you 37-mpg.

Diesels have come very far and are becoming a great option for drivers.  Also, there are becoming more and more models for consumers to choose from.  Of course, drivers should protect themselves with a good auto warranty to avoid unnecessary repair costs.
