You are in the Chevrolet Impala
What is this discussion about?
Chevrolet Impala, Sedan

Instead of steadily making this Impala better year after year Chevy jumps all over the map. The 2000 Impala came out FWD with two engine choices....then a few years later tries a supercharged version, that lasted a couple years, now the small block FWD v8. A couple years from now that will all be dropped and a new RWD version of the Impala will be coming out. I am excited about that but it will take years again to build up a reputaton. Honda/Toyota have steadily improved their products over the years. They have been making Camrys/Accords/Corollas for decades steadily making small improvements every year, learning from their mistakes. As an example of my statement above. Chevy made a lot of models that came and went. The CHEVETTE,CITATION,CAVALIER,CELEBRITY, LUMINA etc. That had to cost them BILLIONS. Instead of a business plan in improving these cars they were sent to the bone yard early. It takes years to build up a reputation as in any business or product, and right now the only Chevrolet with a repuations & longevity and has done very well is the Corvette. GM has to build a car that the people want and to keep improving it year after year to bring the buyers back. Would I like to see the Impala the #1 car nameplate in the USA.......certainly! but making wholesale changes every few years on this model will never get this car to where it once was ......at.#1. Being #1 today is more important then ever........just my opinions.

Thanks charts2, much appreciated. Wow, now I'm glad I *don't* have the 3.9 with DOD/AFM. From several prior posts here, it sure sounds that real-life mpg should only increase 1-2 mpg with DOD. If you're mostly a city driver, then I seriously doubt you'll see any noticeable benefit, maybe 1 mpg more.
I agree with you -- I don't like hearing the same 3 cyls will be deactivated, as that should cause uneven wear over time. I was hoping it'd be like the V8, and would only deactivate a different set of 2 cyls each time to keep it balanced. I'm now thinking that perhaps you don't see any real fuel savings until you deactivate half the cylinders. Running on 3 cyls just sounds odd.
Since I generally keep my cars for 100K+ miles to get my money's worth, I'll gladly trade 1-2 mpg (even at $3+/gal) for an engine that sounds like it may provide the better long-term reliability. DOD is still pretty new, at least in this incarnation. I'd like to see the repair histories on those engines 5-7 years down the road.
I'm not knocking GM for trying to increase fuel economy, but I'm not convinced it will provide the best overall customer economy once an expensive engine repair is factored in over the marginal fuel savings. Admittedly, this is all speculative on my part since they're so new. Who knows, perhaps GM will surprise us all as they generally build pretty good engines, even if they're not the quietest or the smoothest.

I give GM credit for this technology breakthrough in a V6. Like you I hope reliability has also been built in. Time will tell.

Thats correct for the 2006 Impala SS V8 post #1485. The 2007 Impala 3.9 will de-activate cylinders 1, 3 & 5. Making it operate on 3 cylinders is my understanding.

My mother just traded in her 1987 Chevy Celebrity for her 2006 Impala. The Celebrity was still going fine.
If you take care of your car it will last. Chevy engines last a long, long time.

Thats one!......where's the other million that they made... Just kidding! Your right about taking care of a car. I am into collector chevys and there are still many from the 60s still poking along with the original or second owners with the original clear plastic seat covers, and still haven't rolled over 99,999 yet. I wish your mother good luck with her 2006 Impala.

Y'all keep talking about uneven engine wear on the cylinders and pistons but I don't know why the deactivated cylinders would wear less since they are still moving, even while deactivated. The only thing that changes are camshaft lobes that stop activating the push rods and valves. I guess it's possible that the pushrods and valves of the deactivated cylinders may wear less but it's been a long time since valves and pushrods have had failure issues.
I can understand your skepticism but your negative speculation doesn't help anything. Why not give it a chance and see what happens?
As for Chevy starting and discontinuing model lines, it's all about the names; the same models continued on. The Celebrity was a transition to a smaller six passenger car. It evolved into the Lumina (never understood why that thought that name would sell) and later into the Impala. I would guess part of the reason they took away the famous old names was due to the backlash from traditionalists when the Nova name returned on a rebadged Toyota Corolla, the Cutlass Supreme was switched to FWD, etc. The revival of those once grand model names is a testament to GM's confidence that the newer versions do justice to the famous nameplates of old. I think they still have a way to go but I do believe they'll get there with the new RWD platforms. I would love to see new Chevelles, Camaros, Impala/Caprice Classics, even a nice new Cutlass Supreme (although it probably wouldn't work as a Chevy). Those cars really inspired people to love and bond with their vehicle, wash and polish them, etc. These days, the personal pride of ownership seems to have faded from most people. Cars are more like appliances to them and I think that's a major reason why Toyota and Honda have done so well. Chrysler has managed to tap into that old passion to a degree with the new Charger. Ford has managed to maintain it with the Mustang (although I am unsure how they managed to do it through the last couple generations). GM tapped into a bit of it with the new GTO but took the lazy approach they are known for and simply rebadged a lack luster model from Australia. The SSR is truly original but appeals to a limited segment. A more mainstream power house will sell much better and hopefully we'll get one or more in the next few years.
