dedicated 4 cyl. would be a cool mode. That would be sweet for road trips, or when you let your friends drive

 

I say great idea. Seamless, non-switchable. If you want the option without it, pay a guzzler tax.

 

I voted yes for DOD... but I doubt it really matters since I will probably be getting myself a charger instead.

 

Some of you guys are too narrow-minded.

DoD = fuel economy = better emissions = no gas guzzler tax

DoD does not mean poor performance.

Heck, if a V6 can be tuned to sound like a big block V8 by simply changing out a muffler*; don't you guys think that GM is capable of hidding that fact with DoD? Besides, DoD doesn't kick in a WOT when you're actually going to hear the exhaust rumble. It kicks in at cruising speed on the highway.





* I'm referring to the Flowmaster muffler for the 4th gen V6 f-bodies.

 

I'd be all for less highway drone.


3.4L Camaros with a borla or Flowmaster sound awesome

 

1. Have you actually driven a 300C or a Magnum RT?

2. There is a very strange exhaust resonance, possibly from the crossover pipe that's supposed to smooth out the exhaust note in 4-banger mode.

3. Then there's the throttle reponse issue. It makes me wonder if adding DoD added a bit of confusion to the engine management software.

4. The fuel economy is still pretty rotten on the Magnum RT, despite DoD. Didn't R&T's test Magnum RT get something like 12.4MPG? Didn't Automobile's long term test get only 20MPG average?

There's a lot more complexity to DoD system than you're letting on. Look at Honda's system on the new Oddyssey minivan. There's the electronically controlled engine mounts, not to mention a noise cancellation system that's part of the stereo. That's the tip of the iceberg.

The bottom line is that a DoD system will pose a number of maintainence headaches down the road. Just wait a few year until the speakers start to delaminate in those Oddyssey vans. Poof, the noise cancellation system goes by-by and the interior your used Honda van becomes an echo chamber during 3-cylinder mode.

 

I voted yes. I think it would be a good thing for sales. But does DOD mean when you tear apart the motor in a couple years you will have some pistons, rods, valves, springs and whatever else that would be worn and the other half that are still fine?

 

That's the big question mark. Even assuming that the fundimentals of the engine aren't effected in terms of durability (and that's a HUGE assumption) there will still be issues with the systems that are supposed to take the noise and vibration out of an engine that's running on half of its cylinders.

 

I voted no. As much fun as it would be to race Hondas on only 4 cylinders, I believe it's unnecessary. Look at the Vette. It gets pretty good gas mileage for a 400 hp V8. I get 20+ out of the LS1 and I'm close to 30 on the highway even with those occasional WOT spurts... I think it would be good as an option or maybe even standard on V6/ LS4, but the top dog should not receive DoD.

I like my feet having control over THE ENTIRE ENGINE and every ounce of power it makes.

 

Yes because it will put those import guys who are so worried about fuel economy in their place

...but it but it has to be optional and needs a switch. ...needs a switch.

 

don't know about you, but my gmmg can be heard even at idle
i just really don't want that 4banger sound although i would definately welcome the added fuel economy
i'm just trying to have my cake and eat it too

also, on the issue of how it wears, i believe it switches which cylinders deactivate and evens out the time that each set of cylinders are off/on
so there "shouldnt" be any issues with that
