If you could have a hybrid Jeep or a diesel Jeep which would you choose? Would you go for the gas vehicle that only showed a modest gain in fuel economy while, more than likely loosing torque and making going off road nearly impossible? Or would you go for a diesel Jeep that may not have much better fuel efficiency than gas models, but may very well provide better low end torque and the ability to run off of french fry grease?
I think that the answer to that question is pretty simple. Hybrids are great vehicles if you can fit into a Prius. Some of us, namely myself are simply too large to fit into the hybrids that can obtain 60 miles to the gallon. Those hybrids are useful, they serve a purpose. The hybrids that only average 10 more miles per gallon do not. Considering the amount of lost power of a hybrid, you may be better off with the basic gas version of a vehicle. This is especially true when talking about Jeeps. A hybrid Jeep simply would not give you enough power.
A diesel Jeep on the other hand would serve two purposes. First, a driver of a diesel Jeep would not be robbed of the much needed power that driving off road requires. I may be mistaken, but diesels provide better low end torque than regular gas models. The second benefit is of a grander scale. By purchasing a diesel Jeep (note to Jeep: sell diesels in America), one could fill the tank with biodiesel. This may not save you very much money, but it would be a step towards alternative fuel sources.
