If you're hoping that "more rumbly" will be more like "V8-rumbly", that's not gonna happen from any size or configuration of six cylinders.

Norm, why the assumption that he mean't "V8 rumbly". We have our own form of sound that we love...so no need to jump in with a useless comment. Yeah a V6 won't ever sound just like a V8, but if you think they can't sound "rumbly" and have a good strong tone, then you are just ignorant. Nothing wrong with not knowing. It just takes a lot more work to get there than it does with the V8.

GM also tried a 3.0 L V6. It failed misserably because of the lack of torque and HP compared to the 3.6L. If you recall, GM launched the Equinox and SRX with 3.0L V6s and made that the base engine in the CTS. It had exactly the numbers everyone was looking for. It was not an EPIC FAIL, but it was a pretty big one. Took two years to resolve it. It gave you less power and performance and no real FE gain for the trade off.

Now if this is one of those threads (like the mythical 3,300 pound Camaro that everyone thinks is coming) that says GM should make a XXL V6 that gets 35 MPG and offers more HP than the current 3.6 and gives us V6 buyers the performance of an SS for no extra money..........................well we should shut that down right now.

Yes, GM could make a 3.0L V6 and put in the Camaro. Name your displacement. But you will run into one big problem. If you want a bigger displacement for more torque and HP you will LOSE FE, not gain. And if you want a 35 MPG Camaro, you will LOSE HP and Torque, not gain.

There is no free lunch here, guys. You can't just say "invent an all new V6 that gets the HP of an SS and the FE of a Chevy Cruze". If that could be done it would have been done.

And then there is the crowd that says, "I've got a tune and I make 350 HP in my V6". Nice, but your engine and the transmission that goes with it no longer meets GM standards for reliabilty. Sorry.

Basic point - it's just not that simple.

There is not as much talk about a V6 engine. (not talking turbo V6 here...just N/A)

First off, let me say, that with a light enough Camaro...somewhere in the 3,300 lb range, a turbo 4 could be a great performer. Especially if they give it 300HP/300TQ or more power.

But with that said, I feel that there could be good space for a V6 in the lineup, and I really hope to see one for several reasons. The current LFX is rated at 323HP, and 278TQ. I don't see why with some tweaking in the 3.6, that can't be raised to somewhere around 330 - 340HP, and 280 - 290 TQ. Keep the gear ratio at the current 3.27, weight around 3,400lbs like the Cadillac ATS and you have yourself a V6 capable of running mid 5s to 60mph and mid to high 13s in the quarter mile. Not to mention, with the lighter weight, I don't see why 30+ mpg on the highway wouldn't be doable.

Lets take that a step further and say they give the car a 7 or 8 speed automatic. That should help performance further, as well as raise hwy MPGs well past the 30 mark. (offtopic, but I hope they keep the tapshift...yes I really enjoy it!)

If we don't see the LFX in the next gen, then I see a case for an engine similar to the new 4.3 going in the Silverado. One bonus about this engine, is the fact that it has cylinder de-activation. I'm betting in a light car, with the proper gears, that it could return some very pleasing MPGs on the highway. Mid to upper 30s easy. Hell, why would you even need a turbo 4 with efficency like that?? For truck duty, that engine is likely cammed and tuned for great torque, and decent horsepower. I'd guess 300+TQ and HP around the same levels. If tweaked for HP, instead of Torque, (similar to how the Ford 5.0 is for Mustang vs. the F150) it should be capable of fantastic numbers.

So here, in my opinion you have the perfect combination of power and efficency. I know to some, nothing less than V8 power will do, and I have no problems with that. But for me, I really love my modded V6. She runs strong. The only big issue I have with the 5th gen is the weight. Some days I drive my (modded) car and think "damn shes running good!" and at other times...I wish I had another 20 - 30 HP/TQ on tap, or about 300+ lbs less weight.

I have no real desire to move to an SS (although I do love that V8 rumble), and with the weight drop that should be coming, I'd buy a V6 all over again. It would be a fantastic car, and don't get me started on how well I think a nicely modded V6 would perform in a light weight Camaro.

So....what do you all think?

The Caddy CTS will have 3 engine options, the 2.0 turbo 4, the NA 3.6 V6 And the TT 3.6 V6. Those are the options for the Next Camaro. You might see the V8 in a high performance model such as the next gen ZL1 or Z28.

Don't be lecturing me about the sixxer exhaust note without knowing how I feel about the topic. Two of the cars in my driveway have V6 engines. I can play a pretty sweet tune running up and down through the gears on the little 7500 rpm-capable 2.5L in my Mazda 626, now that I've swapped in a more open muffler. It more than makes up for not being all that fast by being satisfying to listen to and a whole lot of fun to drive.

Hell, I'd put an X-pipe exhaust on the V8 car that I have now if it needed exhaust system repair, like I effectively did with the V8 car I had before that. There's just something about the snarl that builds as you're running up through the midrange and it echoes off the Jersey lane barriers or when going through a tunnel . . .


FWIW, I doubt that a 90° V6 engine is considered commercially acceptable for use in a passenger car any more. Trucks, maybe. Being able to run it down the 90° V8 production line is unlikely to still be a good enough reason to outweigh the disadvantages.
