9. No special packages, No hidden costs
Diesel vehicles may be more expensive than their regular gas-powered counterparts, but many can hit 40 mpg on the highway, right off the showroom floor, with no other additions. The same cannot be said of many gasoline-powered cars.
Diesel compacts like the Volkswagen Jetta and Golf TDI, as well as the Chevrolet Cruze Diesel are able to net 40 miles per gallon on the highway without the need to purchase a special eco-trim. In regular gasoline powered vehicles, the only way to get 40 mpg on the highway is to drop down a bunch of extra money for a special aero-kit, active green-technology like grille shutters and other equipment to hit the highly-advertised fuel economy numbers.
