The diesel issue is another way our government is messing us over. The jeep wrangler is about as aerodynamic as a brick. In Europe they are available with diesel, in America diesel is illegal. Diesel is a 2.8 4 cylinder 174 hp, 339 ft lb torque, 23.7 city and 35.8 mpg highway. The hp may seem low but the torque could be comparable to many v-8s. This would be a beast of an off road rig. And also compare favorably to a lot of fuel efficient sedans running the roads in America.
Our version is a 3.8 v6, 202 hp 237 tq 15 city and 19 highway mpg. Countless people have done v-8 swaps on the wrangler over the years due to it's lack of offroad power. Locally even a v-6 swap is popular to a chevy 4.3. Even though the torque is up a little in the new version, when comparable with weight the jeep is a little sluggish in extreme terrain. With the puny diesel engine it would be a very welcomed option to those wanting a little more power. Not to mention the extra cost of fuel, just another way our government is ripping us off. When comparing fuel efficient car designs that run into the 70s in mpg with a common rail diesel and higher, for the same counterpart in America that does in the 30's truly it is frustrating. European gas prices are usually a rule that our politicians argue to try and raise ours. But they get 2 times better fuel efficiency with the exact vehicle. Have an effective public transit system. And a lot of their countries are the size of our states.
