Emission standards are also worth considering. A 2012 study by the University of California Berkeley supports the well-known fact that gasoline burns cleaner than diesel; hence, the effort to introduce cleaner combustion. With the introduction of flex-fuel engines, which are present in Grand Cherokee gas models, emissions are reduced even further.
However, the added mpg of diesel variants also makes for an irresistible attraction. Given this, it won't be surprising to see more of the diesel Jeep models in trusted Indianapolis dealerships very soon, giving costumers more quality options to choose from.
