Porsche Cayenne Diesel: First Drive
By Thom Blackett for Cars.com
Today’s diesel engines are equivalent to a prisoner coming up for parole. Years ago, they committed a crime against society, one with lingering effects and images not soon forgotten. After decades of banishment, they make claims of a rebirth, of adopting new ways that will benefit those on the outside. They request a second chance.
With that second chance comes conditions, and for the diesel, those include burning only ultra-low-sulfur diesel fuel, employing advanced emissions systems that drastically reduce the release of noxious exhaust particles, and making them available in all 50 states. Just to make everyone happy, toss in impressive performance and less of that annoying clanging sound that was prevalent in old diesel engines.
