2006 Changes for the Titan - Page 2

Dodge's "Displacement on Demand" (funny name) sounds great in theory, interesting on paper, questionable in practice.

For city driving, to get 6000 pounds of cold steel moving to speed to maintain pace with traffic, considerable power is required. Using 4 cylinders in this city mode is virtually impossible. People buying a Hemi have never been known to be light footed, patient people. They buy the Hemi for power. Period. In case some have you have not noticed, power in any form is highly addictive to human species. Keeping one's lead soled foot off the pedal is going to be a super human task. Like I said, the system sounds wonderful in theory but when you factor in the human component, the promise of higher fuel mileage extinguishes fast.

I can only see this economizer system possibly being effective in a constant speed highway application.

Keep in mind that every prior iteration of this design has fallen far short of desired fuel frugality in spite of lofty promises and assurances. I predict that the Dodge media blitz for this option will sound irresistable to the masses but logical conscious minds will see how transparent the ad claims really will be.

I hope Nissan doens't do that. Dodge is going to it in a lot of their vehicles, inlcuding the Ram (I think). Goofy thing is, it only increases gas mileage by less than two miles. Not much saving fora risky thing. Cadillac tried it years ago and it stucnk. I know technology is different now, but who knows..

And what about the de-activation-will the same cylinders be de-activated every time. For a hi-way traveler, those four will wear out a lot sooner.

On the '06 info though...Did the dealer mention any 'improvements' for the engine, specifically, more HP and torque!!

sorry skytop...you beat me to it..

What he said...

grunge311 · 07-21-2005, 04:13 PM

Man I hope I can put put an 06 climate control in my 04

Displacement on demand sounds like one more thing that can go wrong, IMHO. I don't know how it works, but all I can imagine is somehow not all 8 commin back on as fast or as soon as you need it.

I think if they do a small diesel it should be a little more powerful, but no need to be too over the top. Save that for the 3/4 or 1 ton market. Maybe 07 we'll see something hit that. I think that's when the new Tundra should be out.

I will be looking at either purchasing another Titan in 2007 or downgrading depending on the "oil situation". We'll have to see what is offered. If diesel is available I'd probably go for that.

We'll see!

My wife's '05 Honda Odyssey has displacement on demand and you can't even tell when it switches from 6 cylinders to 3. It has an indicator in the instrument panel that tells you when it's running on 3 and if you are doing anything more than just barely touching the gas, it's running on all 6. It's purely for highway cruising when you don't need the extra power -- you are just burning more gas. The rating for the Odyssey with DOD are about 4 mpg higher than the models without (28 vs. 24 I think.) I don't know if it would work as well with a large V8 but in the van it seems to work great.

Buzz--

The dealer I talked to didn't mention anything on HP gains, although somewhere on this site I heard the rumor of 315 HP.

ON the Displacement issue.....the BIG difference with the way the current systems work is that the cylinders are still moving, there is just no fuel / air going into the cylinders. So, no combustion, but parts are still moving. they say it takes like 1/50th of a second to get the power back to the cylinders. the driver can not tell the difference. I think if the technolgy cost little to nothing additonal (as Dodge claims), is reliable, gives 2 MPG better on the highway, I think Nissan should do it.

I think the Honda Odyssey gets about 2-4 MPG better with their displacement system. If Honda is doing it, you can bet its pretty dam* reliable.

Ok, I know good facts. I have internal nissan knowledge. 2007 WILL NOT HAVE A 3/4 OR 1 TON! OR DIESEL! It will however have 15 more HP in 2007. They will also have "best in class" brakes in 2007. The 3/4 has been talked about and researched and they are estimating around 2010.

twalker294 · 07-22-2005, 12:26 PM

If you had internal Nissan knowledge, you wouldn't be allowed to share it with the world.

buzzkillwill · 07-22-2005, 12:27 PM

Yeah...agreed, basso-

I think anything that can help with less gas consumption, but allow me to ahve my Titan still-I'm for it...

XXX-"Best in class" brakes...You might get stoned saying that here...
Thanks for the info. What else can you tell us?

Justintoxicated · 07-22-2005, 12:38 PM

No Big Change?

VDC (Vehicle Dynamic(?)Control) available on all, including with locking rear end

Great my 05 is going to be worthless after they do this. I don't have VDC.

IMO Buying a 06 over a 05 for the MP3 is ridiculous. The stock sterio will STILL SUCK Entirely. You STILL have to replace the stock HU to do any kind of upgrades. You can get a CD-player that plays MP3's better than the stock one for like $150 lol

Here's a riddle: if Nissan ( actually UD) already has a remarkably durable and torquey 4-cylinder and 6-cylinder diesel, why not put it in the Titan, or at least the Fronty. The UD 1400 trucks have a turbo intercooled diesel rated at 175 HP and 347 lbs/Ft of torque. They also have a reputation for 300,000 miles of service without significant maintenance. Why, then, can't we get one of these little jokers in the Titan. You won't go 'round whippin' the pants off any Hemi's but you'll pass them at the pump and at the service department many times over. Titan in it's 5.6 V8 form has 379 lbs/Ft of torque. Doesn't look like terribly significant advantage except when you want to blow somebody off the line. If I could drive 100 miles further on every tank of fuel I'd be happier than burning $2 every time I beat somebody to the next light. What do y'all think: Want one that works more efficiently for a longer service life, or want one that burns rubber but costs more every mile? I'm just curious what the market would reveal.

I would buy a longbed deisel in a friggin second.

I don't own the Titan, yet....but if I were to see a diesel on the lot today that got say 21/25 MPG, I would probably go with the diesel. However, I will not pay a $6k premium like domestic trucks. That would take 10+ years to recoup the savings in cost differences.
