Whats the future of GM's 3.6L?
#16
The proof is in the pudding. Their formerly 273hp 3.7 now makes 305, while improving fuel efficiency.

However the 3.7L V6 in the 2011 Mustang is 305hp - which equals about 82.4 hp per liter.
So there's a definite boost of nearly 10% in Hp.

I believe that's the 263hp 3.5L V6 in the new Taurus. Which would equate to about to roughly 75.1 hp per Liter. So the 3.7L version should be about 278hp.

It was/is around 273hp.

They still have PI, but went from single VVT to dual VVT, plus a number of other useful changes to optimize airflow and valve timing. Apparently, they can switch in and out of Atkinson cycle with valve timing too.

What the 3.6 lacks, IMO, is a lusty soul. Or at least a version of it which offers one. I mean, it's a good prime mover, it just doesn't give you goosebumps.
The other day, I had one of my boys in my car and was quickly accelerating away from a traffic light. He asked, "Dad, why do you only rev up to 4000 RPM in the CTS, but used rev your SVT Contour to 7000?" I answered, "because it wanted me to" . That motor (the SVT) had a lusty soul. It loved to rev, and it was glorious. It beckoned you!
I saw alittle bit of that in the personality of the 3.0L, motivating the SRX I recently had for afew days. But it sure would be nice if GM would develop a real enthusiast version of it's V6 - in whichever bore/stroke ratio they deem appropriate.

As for the future of the 3.6L DOHC V6, with Direct injection - I tend to believe it has a great future potential (2012 & beyond).
I believe the technology will also make it's way into the "Next-Gen" Ecotecs(DOHC I4) which hopeful will make more power, yet better fuel economy.
And I would be surprised if the new DOHC V6s, with Direct Injection would range between 2.8-4.0L - with more hp, and even better fuel economy. Note - I also think that GM is going to need at least 3 different V6s - a small displacement (less than 3.0), a mid-level between 3.0-3.5L, and a large displacement between 3.5-4.0L.
Also I think GM should go with a small displacement DOHC V8 line(based off the 3.6 V6 line) - which help with the next gen Corvette, Camaro, & mid-size truck lines.

I'll agree with you about the 3.6. Although my CTS had the slushbox, my impressions are pretty much the same as yours. All revving it seemed to do was make it a bit coarser, like it was straining, like it would really rather not go there. I suppose one of the benefits of a broad torque curve is that you don't have to go there as often, but when you do, it'd be nice to enjoy it more.
