According to the new Car & Driver, Alfa Romaro will be using a GM 3.2L High Feature V6 with Direct injection and it will be making 256HP

I can't wait to see the new CTS with the 3.6L version of this same engine

 

That's barely par for today and sub-par for tomorrow, unless they primarily intend to use this on relatively low-priced vehicles?

 

the current larger 3.6L V6 is 255HP, with direct injection and other tweeks it will be putting out 300HP+ for 2007. I think that is pretty good.

 

Kyle, I think his point is that this 3.2L version is making ~260 hp (what the current 3.6L makes). We are (or at least I am) hoping for something around/over 300 hp from the 3.6L version, hopefully without requiring crazy high revs/sacrificing low end torque.

 

How many <= 3.2L engines out there today are making more than 256hp?

And if you do hp/L, you'd have a 280hp 3.5L engine. Or right about what all but the top 3.5s are doing.

I guess that's 'barely par' so long as you can acknowledge that all of the japaense 3.5L engines are also barely par. How many > 280 hp 3.5L are out there today, what, the top 350Z/G35 engine and ????

 

Currently available:
350Z/G35 coupe 3.5 = 298 hp
TL 3.2 = 270hp
IS350 3.5 = 306hp (SAE revised down from 315)
RL 3.5 = 300hp
Avalon 3.5L = 280hp (engine will be found in next year's Camry as well)

That's what's available right now (except in the IS' case which will be another couple months).

Next up for most of the cars listed above (and the other vehicles that use those same motors) is a hybrid system option which should raise power by 10-15% as well as drop fuel milage to that of a 4-cyl.

That's what I meant about 'tomorrow'. Unless GM has more research into hybrid technology than they're letting on to right now?

 

the only one that beats it is the TL as the 3.5 will be bumped up to 300+

 

I coulda sworn this thread was about the 3.2L and I also coulda sworn that you guys always made fun of people (ricers) for referring to horsepower per liter!

From what the others are saying, it'll be a 3.6L, which sounds like it'll be on part with the Acura RL, IS350, and 350Z/G35

But FWIW, per liter, GM's 3.6L would have to be 304hp to match the TL per liter, 309hp to match the Acura RL per liter, 307 to match the 350Z/G35 per liter, and 315 to match the IS350 per liter (assuming the 3.6 will be measured using the new SAE standard).

 

The other engines you mention are not measured with the new SAE standard. Just pointing that out.

 

I know the IS' 3.5 is. What about the 3.2 and 3.6? I don't think any of others are but I'm not sure.

 

Do those engines require premium fuel as a result of high CR? I know the VQ35 does. Will the new GM motor require it as well?

 

To my knowledge they do; of course they have knock sensors which means they don't technically require it, but then again to meet their advertised power requirements you'd want to use premium.

And I'd be very surprised if the 3.2 and 3.6 didn't require premium either. But maybe somebody can confirm that.

 

The 3.6L requires, 87 not premium. All the engines mentioned by you require 91+ to reach their advertised HP #. At this point it is not known if the 2007 3.6L that is said to be 300HP+ will use 87 or 91+.

The 3.2L is a new V6 in the high value family, and the first that I know of that uses direct injection. Unfortunatly Car & Driver didn't have torque numbers and the Alfa Romero that it is going in isn't out yet, so not much more is known about the engine.

 

Interesting. I know the IS250 and IS350 use direct injection as well, FWIW.

 

Well, I just did some research and it seems as far as I can tell that this is incorrect.

The 3.6L V6 in the LaCrosse CXS (the premium model) only makes 240 horsepower but only requires 87.

The 3.6L V6 in the CTS seems to be no different other than it uses a higher compression ratio, thus increasing the horsepower to 255 (15 more). But it requires premium per several sources I checked (excluding Cadillac.com where I could not find it mention anywhere).
