I can say this, i have heard it will be a supercharged Northstar motor, not sure if it will be offered in the AWD, i forgot the other details, but i'll try to find out more.

 

Blown Northstar making between 430-460hp. I really wish they would use the LS7. Screw OHC fan boys...its about power.

 

Or, just 400hp.

The LS7 will make its way into over V series models later down the pipeline.

 

Nah, its gunna be more then 400. Why spend the extra money on a STS-V when you can get a faster CTS-V for cheaper.

 

can you show me info that says that OHV makes more hp than OHC? because thats like saying a carb makes more horsepower than fuel injection...

 

K...

Mudstain GT vs. Z28
C6 Z06 vs. V10 M5...

Erm...

Shall I go on?

 

Per a given displacement, OHC can make more power....operative word being "can"

Per a given total engine weight and exterior size, OHV will almost always make more power.

Case in point is LS1 vs. 4.6L ford. Well, the LS1 is 1.1 liters bigger you say. Yes, but its smaller externally (narrower, not as tall), and nearly 200 lbs lighter plus its cheaper to build AND makes more power. So I ask, other than a marketing gimmick for buyers that think OHC is somehow techically superior, why would you want it?

LS7 would be sweet in the STS-v but this is all about going up against the new M5 and possible M5 buyers aren't going to care much for a 7.0L pushrod motor they perceive to be low-tech. Doesn't matter if the facts bear it out to be better or not. Marketing isn't always about reality.

 

Refinement. Different targeted price range. Lots or reasons. Plus, why would GM exhaust the Northstars output with a blown motor in the V the very first year its available?

Why is the CTSv going to get a significant upgrade in the near future, but the other V's will not? Who really knows.

 

i don't think we can post the pics until the embargo is up on them. i don't know what that is though

 

The STS V won't be available for a year or so, they are just now going through validation at GM, so we are about a year out from production i believe, and it will be over 400 hp, just not sure exactly how much.

 

STS-V will show up in Jan at NAIAS.
Why not have the STS-V match the likes of the E55 or M5? They didnt have a problem jumping into the ring with the CTS-V. If they come to the table with less then 430hp, its a waste.

 

I've always had the image of OHC having better reliability over time. Whether or not thats true, I dunno. But it just seems like it would be.
I concur...

 

Which would put it at either a 06 or early 07 most likely, more likely an 06 i hope.

 

Any time you have more components (extra cam, extra valves, etc) the chances of component failure go up. Assuming equal engineering skills on the design team, the simpler motor will be more reliable.
