4. You Can Still Drive a Porsche
You know that diesel's reputation has largely been restored when Porsche decides its time to drop gasoline, at least in one model. The 2013 Cayenne Diesel, to be unveiled at the 2012 New York Auto Show, has a 3.0-liter V6 turbo diesel engine with 240 horsepower and 406 lb-ft. of torque. And even with all that power, it still gets 20 mpg in the city and 28 mpg on the highway- not too shabby at all.
5. Bio-Diesels Are the Future
Our supply of gasoline isn't going to last forever, but we can make diesel: biodiesel, that is. It can be made from algae, corn, soy, sugar cane, methane, paper waste, various flowers, and other natural products, so running out isn't an issue. Biodiesel produces fewer emissions than gasoline or conventional diesel, it decreases engine wear and can be used in just about any diesel engine without modification.
Bio-diesels have their disadvantages as well, but all in all, they're basically a souped-up version of regular diesel, amplifying all of its best traits. Efficient, environmentally-friendly, and reliable: diesel's worth a second look.
