But the LS2 and LS4 were performance engines. The LS4 5.3L came after the LS2 6.0L. Take the LS4, which had DOD, and give it DI/VVT and you may be able to get more HP and greater MPG without having to use DOD/AFM. Those same people buying GXPs, Impala SSs and Monte Carlos SSs back in the mid 2000s would probably buy something with those characteristics again.

And as we have seen with the introduction of the 2014 LS3 powered Chevy SS. This may very well be the case for some time to come.

But again the bottom line is GM Powertrain spent years and many millions of dollars developing the Gen V V8 with DI, AFM and DOD for performance cars like the C7.

Well don't forget the trucks...all that money they spent went into a ton of different setups, it only makes sense that they would have a lower displacement HP motor because that would be like putting an LS7 into caddys, trucks, and even the SS and Camaro..the LT1 was "specifically" designed for the corvette but the need for HP and MPG's is needed in many other applications.

Displacement on Demand. The precursor to AFM.

You’re talking about a few different things here.

The LS1, LS2, LS3 have been the base performance engines from GM since 1997. As you have seen the displacement has gone up from 5.7L to 6.0L to 6.2L during the Gen IV LS engine run. This has been done to meet higher and higher performance objectives. With no real penalty in external size and weight from an LS1 to LS3 the added HP and torque from larger displacement has allowed cars like Corvette to remain competitive in the marketplace. If they can maintain the performance increases from the larger displacement and still hit fuel economy targets for Gen V with the new technology there is no reason to go lower displacement.

As for the LS4 powered FWD W cars they will probably not be duplicated again. A combination of CAFE and the advent of modern and more powerful direct injected 4cy and V6's with forced induction options will make the FWD V8 obsolete.

While I completely agree with you and this is something I think about when purchasing a vehicle.

I can say that the vast majority of consumers do not share our passion.

And on GM's list of priorities for developing a new Camaro or V8 engine having an easily modifiable engine is far closer to the bottom of the list than the top. Fuel economy numbers and advertised HP and torque will take precedence because those things will help sell the cars that are powered by these engines.

It’s hard to say GM doesn’t care about aftermarket performance because of the vast amount of products from crate engines to even cars like COPO Camaro but when it comes to modifying street cars they sell it’s just not a high priority.

The only reason they are doing it is to appease the government. If we were all that concerned about mileage, we would be driving V6 Camaros. The gimmicks GM is using to increase mileage is to meet artificial marks set by the government, not by the people buying the car.

I am curious where you saw that it was switchable. I have been on the C7 forum and have not seen anything that says its switchable..
Not saying your wrong, there is like a million posts on the C7 forum so could have easily missed it. Could you send me the link to this?
Thanks!

Good question!...His post was all I saw that said it was...nothing was mentioned in the LT1 links that were posted...This could throw a wrench into everything!...lol

...I just put up a thread in the Vette forum asking about this....Fen replied that their may be some sort of "mode" that limits AFM kicking in...I guess they really don't know what's up yet, either...still speculating over there...

Engineers did an interview, and there was some details in writing about how the Driver Selection Mode system can disable AFM in competition modes, and maximize it's operation for touring/Eco modes.

Certainly don't want AFM to activate that one freak moment when you're coasting to a turn around a track!

I'll see if I can find it - but I haven't been saving C7 documentation like I do Camaro stuff...

It wouldn't surprise me if it was configured to only invoke AFM if you were running at a sustained speed/rpm for a given period of time, a period of time that would not usually be enountered at the track.

"Usually" being the key word. Currently, AFM is programmed to only activate if a given set of circumstances are true, like speed, load, throttle position...very similar to the logic that makes skip-shift (CAGS) work.

It sounds as though this new AFM is something quite special in terms of effectiveness...I can only imagine that means, partially, it's working more often...so that could be bad in a spirited-driving situation. Wouldn't surprise me one bit that engineers made a point to offer a choice, so Corvette wouldn't get bad press from enthusiasts...

Still looking for where I saw that...
