Ordered Overland 4x4

hey Guys,

I just ordered a Overland 4x4 with the 5.7L Hemi, Adaptive Cruise Control, and the 730N RHR options.....should have in 6 to 8 weeks.

This is a FANTASTIC forum, and I have learned a lot. I did have a few questions regarding the truck (I know some of tehse topics have been discussed, but I'm a little unclear, so please no reeming)

- What kind of gas mileage should I expect? The dealer told me 12 city, 19 hwy, but also told me that the truck will drop to 4 cylinders and only kick in full when needed, so this should make enhance the mileage. I know prob a BS line, but figured I'd ask this anyway?

- I personally tested my IPOD nano in the armrest of a Summit the dealer had on the lot, and could nto get any album artwork to come up. I've read several posts regarding this with mixed results. Has anyone confirmed whether or not the album art comes from the mp3 file directly or from gracenote? In which cased is the artwork "supposed" to come up? Ipod vs USB vs music copied from USB

- With the 730N RHR specifically, is it safe to assume that certain functionality is blocked out when the car is in motion? (address input, video, etc) If so, is one of those lockpick devices a practical solution for this and is it compatible with the RHR?

- I noticed that the sound system was pretty decent, however the subwoofer was kinda lacking. Has anyone replaced the subwoofer? I was thinkign of getting a mono subwoofer amp with high level inputs, and replacing the 8" with somethign a lil more robust. I wonder if the subwoofer compartment will have space for an amp....

Thanks in advance for everyones help/guidance

Re: Ordered Overland 4x4

Congratulations on your purchase! New Jeep is by far the best looking SUV out there. I am, however, disappointed at the 5.7 Hemi V8.. I tested one a few weeks ago and I couldn't believe how heavy the vehicle felt, I own a 1996 G.Cherokee Limited V8 with the 5.2 Magnum block and it does feel faster with only 220hp. I've seeing the SRT8 and that will be my choice. Also, and aswering your concern... dropping to only 4 cylinders won't help much.. it won't amount to much.. since the other 4 cylinders will have to work twice as hard to carry the "dead" ones. Don't expect any mileage enhance or fuel savings at all... it's all BS to attract new customers. Just picture yourself running on one leg only.. you still have to carry the other one so your OK leg will have to work harder than ever to carry your mass plus the dead weight of your broken leg.

This is a completely inappropriate analogy. The point of dropping out four cylinders is that when you are cruising (not accelerating), you don't need the torque that you need when you are accelerating. To maintain a steady speed, all the engine power is needed for is for overcoming rolling resistance of the tires, internal resistance of the engine/drive-train, and air resistance. (BTW, At higher speeds, air resistance dominates because it goes up as the square of your speed.)

"Half a Hemi" is indeed sufficient to maintain highway speed. So when you don't burn gas in four cylinders, you save that fuel. BTW, Cylinders don't "work harder" - all you can do is make them work "faster" (increase engine speed) and convert that extra engine speed into more power at the wheels through gearing.

I think what Insider was trying to say was that if all 8 cylinders were running you would be able to generate the power you need for cruising at lower RPMs. OK - but engines have optimal speeds where they produce the most power for gas used. I'm sure you'll find that the Hemi is more efficient at the higher RPM with the four cylinders.

With all that said, you'll need to refer to published reports on how much fuel you can expect to save. The thing to remember is - it's a 3 ton vehicle that uses a lot of fuel to accelerate. If you do a lot of constant speed highway driving, you should expect to get some savings from the dropout feature - if you drive around town, speeding up and slowing down, it won't help you.
