I believe this is what is it called - does the 6th Gen V8 Autos have this or something similar?

Thanks

The V8 definitely does, and I believe the V6 does as well, why do you ask?

was hoping that they had gotten away form that.

why? these engines have been out for 3 years and nothing alarming so far.

Just preferred the ol V8 without it.

any particular reason? I haven't noticed any negative effects associated with it, Im still in break-in period, so I haven't been in V4 mode and mashed the throttle, but everything is transitions smoothly.

Also, don't expect it to go away. Itll only get more draconian as CAFE looms. Be glad we can still get a V8 in a car, and if you want it gone, get it tuned out.

The break in guide says to avoid constant same speed driving, you actually dont want to be in v4 mode during breakin.

My interpretation (and Becky's suggestion) is to interpret that as "no cruise control"
I only commute about 10 minutes to work, have about 50/50 city/highway driving, and the highway varies from 75-50 mph depending on the stretch. Not to mention, you can accelerate very slightly while in V4 mode (and even more slightly when pointed downhill in V4 mode)

It's honestly very difficult to tell when it's switching from V8 to V4 mode. You also won't experience any drone. You get a V8 engine that can make 32MPG easily at cruising speed. Win-win.

I don't like AFM on the highway, heavy vibration and shuddering when it goes into V4 mode, around town is fine. The reason I am working with Range again to try and get a working Range device for when I take road trips. Range works great, if it doesn't throw CELs...having another one sent to me by early next week, will report back if the newest module with the newest module eliminates CELs, fingers crossed!

Something is wrong with your car if you have heavy vibration and shuddering going in and out of V4 mode. Mine isn't even noticeable.

Its been flawless for 75000 miles in my '14 silverado as well.

I agree with Megahurtz on this. I can't even tell when mine switches unless I have the screen up that shows it.

I have to agree with the other guys as well, I cannot feel it going into V4 mode. No hesitation, nothing. I would get that looked at!
