I was thinking, attempting to lead in every segment is just not possible or economical or even necessary. GM has great V8 powerplants, and high-end tuned V8 engines from GM are quite a tech feat.

Having said that, this V6 is "good enough". It doesn't need to have 308 HP to beat Nissan's offering, it doesn't need to top HP from Toyota, or whoever - all it needs to be is a good, reliable engine that delivers good performance and gets decent fuel economy. It should be powerful, but whether it's 302HP or 320 HP is only 6% difference.

Who has 320?

Cadillac is near the top from what I've seen (although all that really matters is that the V6 is 300+)

Lexus IS = 306HP
Lexus GS = 303HP (and 290HP for the V8)
Infiniti G35 = 306HP
Acura RL = 290HP
Acura TL = 286HP
Mercedes E350 = 268HP

and those are all 3.5L engines. The CTS is also expected to be rated higher than the STS although I don't expect anything over 310HP.

I was replying to a comment on how this engine should've been at 320HP.

edit: Isn't it interesting that Audi, BMW, Mercedes are way lower in the HP than the manufacturers you listed above, and they have no issues with that.

I applaud GM for making this choice to help their customers save money. Especially with fuel prices as high as they are now. It's too bad most folks don't take this into consideration when comparing stats among vehicles, or even factor this into their purchase decisions. GM should advertise the heck out of this, it's almost like getting 5-10% better fuel economy.
My rational side agrees with you, but my irrational side wants to see what the HP would be with the engine tuned for premium. Of course, that would make the V8 even more superfluous.

Maybe when Cadillac gets their own 3.8/4.0 variant in a couple of years....

There is NO WAY any V6 would make a V8 superfluous!!!

Capacity equals torque. It's something that the high revving V6 can never overcome! Please remember that!!!

In the end, I'm not complaining. I just wish they were segment leaders in HP again, especially in a segment that the buyer does pay attention.
You don't better acceleration times of a competitor unless you out-torque the competitor's engine. Maybe GM should tweak their engines to produce more torque across the band. Then maybe techno snobs will take GM cars more seriously?

Unfortunately, people do make purchases based on paper figures... It's a concept that GM hasn't grasped! Come to think of it, I don't know if any self-professed hi-tech nut would ever consider GM products before Euro or *** when it comes to purchases based mainly on rated performance of hi-tech engines.

I believe the 2008 G37 Coupe is rated at 320 hp.

Agreed 100%.

I've been saying this for the last year or so. The 3.6 (in any configuration) needs to be the top engine in the Colorado and Canyon. Let the H3 Alpha keep the V-8.
This would let GM compete with Nissan and Toyota in the compact pick-up segment. Well, almost. The twins need a better interior and 6 spd transmissions (both manual & autos).
But I don't see GM doing that as they've ditched the ZQ8 package and the Extreme and the 5 spd mated to the I5. They're not interested in a performance oriented 355, or so it seems.

they didn't ditch the zq8 or xtreme packages, where did you get that from?
I'm a member of coloradofans.com as well, visit there daily and I would've definitley heard that bit of info.

Correction: I read today that the G37 coupe should be rated at 330 hp.

Whatever. The Lexus GS350 gets better acceleration times than the GS430. I know which one I would pick (the GS350 gets better mileage too). I know, I know, at 2000RPM, the V8 is better, but the car has an automatic, so that point is pretty moot for me.

Sorry but I think it would be stupid to want this as the top engine in the 355's. A high revving V6 instead of a cheaper more powerful V8 in a truck????

HP typically wins drag races. The gear ratios take care of the torque multiplication just fine. I know my 232ft-lb 3.2l Acura TL will out-accelerate a 3rd gen 5.0l TPI with 300ft-lbs, and the Acura weighs more.
Yes, the comparison is ridiculous, but it was the easiest thing I could think of.

I'm excited to see the new CTS with this DI engine in it. I can't wait to test drive it with the 6spd manual.
