So Long V8 Cadillacs

A lot has been talked about since the last time I checked this thread but let me add my comments to these.
Exactly right. The world has passed the existing Northstar by. That is why the new V6 is so popular. Why pay more for nothing in return? Lexus did the same thing with the GS430 and it's a good thing they finally put the new V8 in there.
This is one of my problems with the CAFE issue. The cost will be a problem. Can anyone here really justify in a cost breakdown why a diesel engine costs almost $1500 more to produce than a gasoline engine? How much do you think these additional technologies are going to cost? Where do you think that money is going to come from? In the end the money is going to be coming out of the consumers (that we be "our") pockets.
Do you really believe that the new CAFE rules will lower oil use? Do you realize how many more cars are on the road now vs. 10 years ago? Those additional cars use gas (oil) too. This trend appears to be holding meaning that even with CAFE oil use will still go up! You want people to stop using oil? Tax the heck out of it or limit consumption (did I just say ration?). In a free economy know what that means? Price goes way up! IMO that is how you use less oil not CAFE.
Actually technology doesn't always get you there because sometimes the cost isn't justifiable. For example, if an average SUV that meets new CAFE standards ends up costing $100K (in today's dollars) it's not going to sell.
Sometimes new government standards or market forces force consumers to just lower their expectations. For example, in Europe most people drive tiny cars not because of small roads, but because gas and cars are so freaking expensive they can't afford anything better. Technology really hasn't overcome this.

Bush based part of both his 2000 and 2004 campaigns on lowering oil use and in alternate fuels for vehicles. He is only doing what he said he would.
Count your blessings.........if Al Gore had won, he would have us all riding bicycles.
This way, we will still have real cars..........though perhaps less powerful ones. And there's a whole lot more to a nice car than just 0-60 times. Too many of us have become addicted to speed.

Yes, that's true, flip......and I've said, in earlier posts, that I didn't think Caddy (or GM) would drop V8's for its big, ful-size trucks and SUV's either.

So, thy may or may not actually lower oil use, but they WILL check its growth.

An honest difference of opinion among us, that's all. Not all of us crave high-performance, and feel that the RL has an adequate level of performance considering its weight, sturdy construction (by today's standards the car, inside and out, is built like a tank), and its intended use......it is not a racing car or super-sports sedan. In fact, that is one of the things that may be affecting its 0-60 times....this car has QUALITY, heavy-duty construction inside and out. You won't find hardly any cheap, flimsy parts in this car....even in interior trim where you do in so many others. I drive and review a lot of cars....this one, easily, is one of the 10 Best I've ever done (yes, the LS460 and GS 300/350 AWD are also on that list).
However, trust me...........we DO respect your views as well. I know that you, Henry, and others are adament that it should have a V8.

NVH?
GM just didn't want to invest in a replacement for the aged 4.6 Northstar. Last time I checked, the toyota 4.6 found in the LS makes 60hp more than the same sized 4.6 engine in the Cadillac STS.
I don't think I could take serious a premium luxury sedan without a v8. It is kinda like the T100 trying to be a full size with a 3.4 v6.

V6's have inherent challenges of NVH because of the 3 cylinders a side being an odd number. Balance shafts and other techniques are used to minimize this.
If you drive a V6 vs. a V8 version of the same car, they're night and day (except at idle where many manufacturers have ensured almost any engine is quiet and smooth)

The reason that push-rod engines are more RPM-limited is that the lower-mount camshaft, upper and lower pushrods, and rocker arms combine at high RPM's to cause valve float. That is not a problem with the simpler, more direct OHC/cam lobe valve actuation.

Depends on what kind of racing you are talking about.....pushrod engines are more RPM-limited than OHC's, but another advantage you didn't mention is that they have more torque at lower RPM, which is what many American drivers want. OHC engines need more RPM's to produce max torque and HP.

While the original press release says that the future of Cadillac V8s is uncertain, everyone here seems to be rushing to the conclusion that Caddy will not have V8s and I definitely do not agree. What was unusual about the Northstar was that Caddy developed it and it had limited applicability to other models which made it very difficult to justify. Chevy is still doing some nifty V8s and of course Holden is being drawn upon more and more by GM performance so I just read the release to mean that Caddy will use corporate V8s but not develop one of its own. The release just says they are not developing a new V8, not that Caddy has decided to not make any V8 models in the future. Of course, that press release may follow in short order but for now I read it to mean that there will just not be a Caddy designed, limited use V8 developed, nothing more.

before you jump on that boat, remember that NASCAR as well as the NHRA mandates pushrods to discourage technology wars and to keep costs down. They want to concentrate on racing and the drivers....
