DoD / Displacement on Demand was the original name GM gave it, then they switched to AFM/Active Fuel Management. I don't believe there was a technical difference between these two, just a marketing...

Small world! Did you have a Stingray C8? I've seen a few running around the general Addison county area. I sold my C5 and I'm in a Chevy SS sedan dad car now for the car-seat space.

I agree with the overall premise of your post, however this number stuck out at me. The article in question says "some 450 lbs", yet you're saying 5-600 lbs. MT's numbers at the end of the article...

Is it actually down on power or is it just a rating difference like DIN vs SEA HP? Although I guess they have to have particulate filters on gas cars there now? So probably really is down on power?

When I lived in Winter Park/Oveido, FL about 15 years ago I used Carl Black a few times and had no complaints, but it was also a more mundane car and not a Corvette. We also liked Holler Chevrolet on...

I think at that point it may get more logistically complicated.

One the one hand, they're taking advantage of the money they already spent developing C8, but on the other hand, if trucks and other...

I don't disagree but LS2 to LS3 and auto trans "upgrade" 2 generations in a row tells me that they don't necessarily worry about things like that. Plus the LS1 upgrades and the LS6 upgrades in C5.

Good info thanks. Even more reason why the current C8 supply/demand issue wouldn't necessarily mean that GS wasn't being worked on/planned!


It stands to reason that Gen V will be phased out from...

If a version of Gen 6 replaces the LT2 in the C8, then any GS made would likely continue to use the base engine (based on C6 and C7 GS implementation) with wide body, but would have the Gen 6 engine...

I hadn't seen that yet, do you recall what thread it's in? I didn't see a new topic for it, so I'm thinking it may be buried somewhere? Not doubting you, just curious for any extra details that may...

Is the Lambo SAE certified though? It's something that GM has done since 2005 with the LS7, but my understanding was power rating to SAE J1349 was optional. There's no requirement that the Lambo...
