How hard is it to, increase valve size +1MM, increase port volume, and change runner length and cam duration. Shade tree mechanics re-engineer vehicles like this in an afternoon.

GM does do that! Look at the Gen III/Gen IV V8 engine line: All shapes sizes and colors.


As for increasing valve size, changing a cam, etc., this stuff isn't cheap or easy when your dealign with mass production. There's tooling (or at least purchasing) costs for even the most simple engine changes. On top of that, all changes need to be validated through thorough testing and certified by the EPA.

It's easy for your shade-tree mechanic to do this, as he only has one car to modify. He also doesn't have Unlce Fed regulating what he does to his car, assuming that he's emissions compliant.

A lot of criticism of mgescuro.....
I would bet that he and many of us here, criticize GM and Cadillac because we want them to return to their glory days, with great cars that we would be proud to drive, with advanced tech, great customer dealer experience, great dramatic style.

Just my own observation here . . .
I think the best part of reading these posts is how well some of you know each other. Obviously I'm a lurker who reads the posts and only makes a few sarcastic comments. Thanks for the enjoyable reading during this stressful time.

BTW, in my opinion, Caddy should have the premium motors, but I have no problem sharing platforms between brands. There has to be a happy medium.

Yeah well.... I get that a lot.

Lemmings... all of 'em!!

They should bring out more factory hotrods. How about a 350 horsepower Turbo Alpha Cadillac, make mine the convertible. I'd buy one in a New York minute!

Tell me about it, with some the newer vehicles, you need either specialized tools or a PhD just to change the sparkplugs.

On his first post in this thread I thought mgescuro was being a little over the top but he does have somewhat of an argument.

First I was thinking that if you make an engine more than good enough for Cadillac and put it in the Chevy also then what is wrong? I guess at some point an Equinox owner might come along that is a car freak like all of us and say to the Cadillac owner:

"Nice suv, what engine does it have?" and he might say "the base 3.0L V6" and the Chevy owner will then say "Nice engine uh?, I've got the same one in mine!"

How's the SRX owner going to feel? Regardless of how nice the motor is he's going to think he's got a Chevy motor in his Cadillac and he might just have paid too much. He might even start to wonder how different the 2 vehicles are and think he got ripped off.

Why not give the Cadillac motor something extra? Hopefully once GM gets all their motors out of the dark ages they will start to do this. Perhaps in the next generation of vehicles when ALL the engines and transmissions are already of the latest design and technology (at least meaning no 4-speeds or OHV Chinese made value motors) in ALL the GM vehicles they can work on providing the newest features and engine gadgets on the Cadillacs first and let them trickle down to the other brands. And as they trickle down the Cadillac motors should already be getting something newer and better.

Why get personal anyway? Just block him if you don't like his views.

Of course we want GM to succeed and produce competitive products. I get sick of listening to people say they won't purchase American brands because they are American. Obviously, the image issue is still a big one, but the SRX was being bashed here about its base engine.

There is no shame in sharing an engine around the empire, especially if GM manages to "do" the engine correctly. It makes sense to stretch each investment dollar as far as possible, and it's completely sensible to share parts that a significant majority of consumers-most of whom don't understand GM's brand structure anyway ("You mean Saturn isn't a Japanese brand?")-are unaware they're shared.

Besides, as others have pointed out, other successful companies have been at it for years. It's a "What's good for the goose is good for the gander" kinda thing.

Good write up and excellent news.

I hope we hear some more definite news on the 2.3L I4 soon.

I bet this would make an excellent optional engine in the Cruze, HHR, and maybe even the Malibu.

Not only would it help to better distinguish any vehicle that used a 3.8L/4.0L DI HF V6 from the other GM vehicles that use the 3.6HF, but it would also reduce product overlap and reduce the appearance of badge-engineering. A 3.8L/4.0L DI version of the HF V6 would be ideal for any full-size GM model as a base model V6 powertrain option. Nissan, Toyota, Chrysler, and Ford have 3.7L-4.0L V6s powering their SUVs and crossovers for extra torque output so why shouldn't GM do the same with theirs and also spread a 3.8L/4.0L DI HF V6 into their full-size sedans as well?

o.0 Because the old 3.6 already competes with all those above mentioned v6's? Let alone the DI HF. Well all but chrysler.......the pacifica was the answer to a question that no one asked according to motor trend. Looks like it got people's interest to ask though.

Most of the time I agree with what you have to say.....but you can afford to spare us just this once. This kind of thing (engines being built by a downmarket brand being installed in upmarket cars) has been going on for quite some time. Cadillac and Oldsmobile owners were squealing about the same thing when Jimmy Carter was running the land!

Besides, I would think that someone with your opinions would recognize that engine-sharing is perhaps the least of Cadillac's problems.

I think a lot of you are missing mgecuro's perspective. We're seeing it as , " Oh wow, the Chevy is getting the same engine as Cadillac uses! Awesome!" Where his perspective is, " Why am I getting the same engine that is found in the common Chevy?" He doesn't mind that a similar architecture is in the Chevy and the Cadillac. He wants something to distinguish Cadillac's version of the engine.

Sort of like with Saab. The 9-3 Aero shares the same 2.8 V6 with the CTS( last gen and I believe it is offered in Europe with the current one), but it has a turbo on it. He wants something offered on this new 3.0 V6 in the Cadillac version that you can't find in the Chevy version.

Aaaaannnnd we have a weiner....

[gmhashope]

I agree with GM using the 3.0 and the 3.6 in both Chevrolets and Cadillacs, but I also agree with that Cadillac should have a top of the line engine Chevy doesn't have. IMO, GM should have never stopped working on the Northstar replacement.

[c5d2h1r1]

These engines are going to really help out in the power and fuel economy department, I wish they had more info on that 2.3L, the 3.0 liter is great, wonder what else they're going to put them in...
