2010 JK Sport driving impressions

Top of the day all,

This weekend, I finally had a chance to evaluate my '10 JK 2Dr. Sport (stock). As such, I wanted to make a solid and honest review of it, and compare it to my old '00 TJ Sahara.

I put about 160 plus miles on her this weekend, and was surprised to note the '10 JK gets considerably better gas milage than my old '00 TJ. I filled up the gas tank and after about 160 plus miles, my fuel gauge showed a little over a half tank of gas remaining. My old '00 TJ would get about 100 miles or so at the half tank marking/level. I had a K&N drop-in filter and a Borla catback on my old TJ, and I swore it increased my milage...

Now, here is the question/perception: Based on my extrapolated fuel economy/milage of the JK, if I were to continue to drive predominantly city to highway mileage, I should/would see about 320 plus miles per tank fill up. The gas tank holds about 18.5 gallons of fuel. I calculated conservatively that I would average about 17.5 miles per gallon city/hwy mileage. Not too shabby b/c I'm a moderate to fast driver...

My old TJ usually had to be filled up around the 210 - 220 mile range per fill up. If memory serves correct, the old TJ had a 20 gallon gas tank (or was it 15 gallons?). Assuming I'm correct, then my old TJ only averaged about 10.5 miles per gallon with predominantly city over/hwy driving. If the old TJ had a 15 gallon gas tank, then I still averaged only about 14.6 mpg. I calculated my fill ups and actual mileage conservatively, so the actual mileage would actually increase by about ten percent or so.

Again, pls note, I'm going on memory, and my numbers could be off a little, but not much...

A couple observations I made this weekend: The 2Dr. JK gets a semi bad rap for being slow and thirsty. IMHO, it is a jeep which we all know comes w/terrible drag coefficient. This obviously effects fuel economy and performance...
Knowing this, I've always purchased the Jeep as either my second or third vehicle. The point I'm making is, if consumers buy a Jeep as their primary (Daily Driver) vehicle, then yes, several consumers will be disappointed w/the poor gas mileage and marginal street performance. Those consumers who know what they are purchasing (aware of Jeep's street weaknesses), will not be disappointed b/c their/your expectations will be in check with the car's street limitations. However, OTOH, lookout, when the time calls for the Jeep's off road prowess/inclement weather superiority, then you'll be glad you made the choice in purchasing this fine steed!

Additionally, I don't think my JK is that slow... It pulled pretty good for a Jeep out of the hole when accelerating from a dead stop, and the only time I had to push the pedal to the metal was when I came across a long and steep incline, which prompted me to really step on the loud pedal to get the JK to move up the incline at an authoritative clip. I can say w/out reservation my new JK would run circles around my old TJ. Pls bear in mind, my new JK is a four speed Auto tranny and my old TJ was the old three speed auto, which was a very lame transmission.

All, I also noticed the gas pedal is a little heavy/stiff? This may contribute to the slow response/sluggish acceleration of our JKs. A stronger push of the loud pedal should remedy this complaint?

If I could make one last comment in reference to the poor performance of our Jeeps/JKs... As a true car/motorcycle enthusiast, I'm of the strong opinion those consumers who load their Jeeps with a lot of heavy off road equipment, raise their Jeeps, and even those who elect to purchase the four door over the two door, will further reduce the performance and fuel economy of your Jeeps. Performance comes down to reduced weight. This is why I chose the two door over the four door; why I chose the Sport over the Sahara and Rubicon. I would have preferred the manaul tranny over the auto, however, I had to select the auto so that my spouse can drive it. She luvs Wranglers...

I luv the JK! It is the most fun, functional, versatile, iconic, niche vehicle in existence. If anyone is on the fence about buying a new JK, buy one, you will luv it, especially if you make some of the considerations I tried to highlight above. Pls note, the above are merely my thoughts and opinions.

All, this is my story and I'm stickin to it.

B/R & V/R,

I got my Sport Unlimited about a month ago. Driving it back and forth to work. Been pleased with the economy on the road. If I nurse it, I can average over 20 mpg back and forth to work. If I drive heavy footed, it drops quick. I have 4WD and 6 sp tranny.

One of the reasons we went for the Unlimited is for the 3,500 lb towing rating. This past weekend, we loaded up the pop-up camper and took it to Florida. Threw the surfboard on top and drove it at 75 mph down I-95 to St. Augustine. To no surprise, the economy went down. But it pulled like a champ easily at 75 mph and returned about 15 mpg economy. I was downright thrilled!

On the way back, same result - 15 mpg. I can live with economy like that. Traded in a Dodge 2500 with Cummins turbodiesel for this and the trade is looking good so far. Since I don't tow much it is actually a nicer set up for me. It isn't as fuel uneffiecient as I was expecting. More importantly, the wife is stoked!
