Hemi dying, caddy cancelling v8s?

oh noes

Thanks to China, India for taking more oil and OPEC.
I heard the GM was thinking about the V8/6/4 again that was tried in 79 and 80. Watch the V8 Camaro will have a V4/hybrid by 2015.

Makes sense to me. It is hard for a shrinking company like Chrysler (Cerberus), one that is trying to regroup, to make broadline engines that get bad mileage. The new CAFE numbers are going to kill those engines in mass market cars, and they aren’t in a position to keep making low production number stuff. They already have the Viper for that.

Displacement on demand is already in production cars. And a hybrid Camaro might not be a bad thing.

GM has had Displacment on Demand/Active Fuel Management since 2005.
The Camaro Concept has an LS2 that has AFM.

And its not China's nor India's oil consumption that is hurting. Speculation in the oil market has driven up prices of oil based products for some time now. We also dont have enough refineries to process the oil we make now.

GM didnt kill V8's. GM ended thier Ultra V8 engine a DOHC V8 that would replace the Northstar V8 engines in Caddy, and give them a powerful V8 to keep up with the rest of Europe and Asian has to offer.
GM will continue on with the Gen IV and upcoming Gen V V8's for the cars we all know and love

So basically if we secretly lobby the speculators to believe the prices will go down, the will?

Al, does Demand/Active Fuel Management actually work? I have heard nothing about it making any kind of difference. I know it was a failure in 80. Of course now the electonics and computers are better.

Lets do it.... pretty sad what makes the oil prices go up isn't it? If they call for 20 MPH wind in the gulf of mexico they have to jack up the prices because the plants might blow over....

It depends. If you are stop and go, it wont do much. If you drive highway, then yes it will. Everyone who reviews the GM system says its seemless and you cannot tell when the engine goes into 4cyl mode.
The 8-6-4 system as a great idea, but did not have the computing power that modern ECM's have.
Yes it does work, and does a great job.
GM has AFM on several cars and trucks that are equiped with V8's.
GM also uses it as part of its 2-Mode advanced hyrbid set up.
Mode one is electric motors power truck around town
Mode two is at highway speed, the 4 cyls shut down and electric motors can assist in pushing the car foward instead of reactiviating the other 4cyls, to continue to get better gas milage.
Does it work? City EPA numbers of a Tahoe Hyrbid are the same to that of a 4 cyl Toyota Camry non hybrid. Not too shabby for a big SUV that holds 8.

Chrysler and Honda both use a similar technology. Chrysler calls it Multiple Displacement System and Honda have Variable Displacement system. MDS is available on the Hemi V8 in truck and cars with the 5.7.
VDS in Honda's can go from 6 to 4 to 3 depending on need. Recent reports have shown that its not a smooth and there is a noticable shudder when driving the Honda system.
