Saw this on GMI today:

http://www.gminsidenews.com/forums/f...engine-100223/

Looks like it's also getting the direct-injected 3.6 motor (LFX), which probably means 310+ HP, though less torque than what we have now.

I'm not so excited about the engine as I am about the transmission. This could mean we'll finally have the missing pieces filled in for retrofitting this trans into our cars.

Christ! Will they kill that car already? The W-bodies should have received that 6 speed automatic back in 2007!

I'm not sure about the missing pieces. It'll probably get the 6T70 though.

Also remember that since it's a V6, it'll probably come with a completely different ECM than what we have.

I'd be interested in seeing how this gets put together.

I also wonder if it'll get Hi-Per Strut (doubtful).

Hoping for the best.

But where's the Commodore?

I still want the Ute as an El Camino!

From what the article says, the car is getting no other changes. Makes sense, as the W-body finally sails off into the sunset in 2013.

Still, it looks like we'll have all of the pieces now. Its just a matter of putting them together.

i defientely want the ute to be here more then any other car

I want a manual!
Nice find though.. and thats a lot of power for a six.

Here's another article on it:

I know it lacks torque but what are the odds of the 3.6 Impala being faster than our cars...? The same architecture in the heavy Camaro is as fast.

It really depends on how you measure "faster" and the gearing the 3.6 Impala gets. The LFX 3.6 will probably have a little more HP stock than an LS4, but it's also going to be short on torque by close to 50 lb-ft, like you mentioned.

My guess is, in a stock-to stock race, the LS4 will launch harder and be stronger up through about 50 MPH or so, but just as the our car starts to fall on it's face, the 3.6 will be finding it's power band. I think the 1/4 mile times will be similar, but the 3.6 car might trap an MPH or so higher.

It will be interesting to see, and we won't have too long to wait, since the 2012 model year will get going in late summer!

Would suck to be slower, on any measurement, than a rental agency Impala. Especially if it has a better tranny that is not made of glass.

It will prob run like a new camaro at that point they will just have to get their little feelings hurt

I should have said quicker. I predict 13.9-14.0 @ 101-102, like you said. Sad times.

LS1 Racing

No doubt.

Anyone know what the 3.6 aftermarket looks like?

Super LaX

LS4 > LFX, torque is still king.

I predict 14.4 - 14.6 @ 96 mph, or a little quicker than a Malibu LTZ.

Battle_Ravage

I'm sure parts can be adapted from the LY7 and LLT, they're all over the world, so I bet the aftermarket is better than ours.

The LTZ had 250 bhp. The LFX is in the 300-315 range.

Hmm...Maybe I'll rip the emblems and gear out of my '06 and trade it for a lightly-used 2012 in a couple of years. They pretty much give fleet Impalas away, anyway, so I'm sure there will be deals to be had.

I love the LS4, indeed, I love all of GM's Gen III/IV V8s. But I hate all of the compromises they made to get the V8 into the W-body. We got screwed on the intake and exhaust, as well as the transmission. If the 3.6 car turns out to be less "crippled", I'll seriously consider it when the time comes.

Battle_Ravage

When that time comes I'm going a different direction. Hopefully that's a while from now.

Only for a while.

That first gear ratio in the 6 speed will help that Impala off the line. And like LS1 Racing said, the moment we fall on our face (high 2nd and beginning of 3rd gear), the new 3.6 queen might catch up.

Of course, this is all dependent upon engine numbers.

Ideal situation for us: camshaft change to linearize our torque curve and 6 speed (6T75) swap.

OHC and DI>Pushrods and a cam in the block. Efficiency is king. It's the reason you get outrun by all those pesky 281 cu in mustangs.
