Could the 6th Gen get the Caddy 3.6L Twin Turbo V6?
 
I was reading my new Motor Trend and saw that Cadillac has the new GM twin turbo 3.6L V6 available in some of their 2014 models. It is rated at an SAE-certified 420 horsepower (313 kW) and 430 lb.-ft. of torque (583 Nm). It is the most powerful V-6 ever from General Motors.

Could this be a good candidate for the 6th Gen Camaro?:popcorn:

Here's my thoughts: No and Yes.

I'm really thinking that GM will keep the TT 3.6 exclusive to Cadillac (at least for the duration of the first ATS generation and third gen CTS), I wouldn't rule out a TT V6 in the 7th gen Camaro (assuming a 7th gen happens).

All that said, I wouldn't mind seeing a TT V6 Camaro to slot between the regular V6 and the V8 models. I think it would expand the Camaro market a great deal.

Hope not lol

It might, but thats only 420hp.....you can get a turbo or SC and have 500 plus right now. :thumbsup:

Here's the thing, the LF3 (I think that's the name for it) returns MPG on par or less than the LT1 V8. They produce similar HP numbers as well with the V8 having the slight edge. The V8 is much less complex, which means it costs less, and it is more reliable. With that in mind, I don't see this engine touching the Camaro. Chevy HAS to offer this car with a V8, but they don't have to offer it with a TT V6, since part of their customer base looks for a SB V8. Personally, I think this engine was created to allow similar V8 hp numbers, yet have a more refined engine for the luxury market. A pushrod small block chevy is certainly not refined for a luxury market, so they made the LF3.

Good reasons not to put it in the Camaro....just as good of reasons not to put it in the Cadillac as well, yet here we are. I don't get the refinement angle in the Cadillac. How is a 60 degree V6 smoother and more refined than a V8?

A DOHC V6 is smoother than a pushrod anything. Sit in a V8 Camaro at idle, and then go sit in a Mercedes V6 at idle. There is a complete difference. The Camaro is louder, and it shakes due to the cam. Of course, if you buy a V8 Camaro, you like these things. If you're buying a cadillac, you won't like these things. Caddy is trying to be more European, and it can't do that with a small block.

:word: Well put, totally agree!

Sounds reasonable. The TT would likely be priced as the V8. If I wanted a 6 banger I'd have kept my SGM RS and worked with that insyead of dropping another 20 grand on my SS. For those of us who lived when 4 barrel V8 was common and dirt cheap I might add nothing compars to a crammed up 8 cylinder beast with a deep exhaust note.

I don't think we will see it in the 6th gen either...at least not upon initial release. Maybe sometime down the line.

But it could be awesome. Simple tune and you've got 500HP/500TQ with a very broad TQ range.

I don't fully agree. A V6 is inherently rougher than a V8 all other things the same, pushrod or not. In a V6 luxury car, they just put more into things like engine mounts to insulate the rest of the car from the engine. The engine isn't necessarily smoother, the vibration just doesn't get transmitted as much. And the somewhat shakier idle of a higher performance engine has more to do with the cam profile, not the position of it on the engine. And besides, the LT1's VVT will probably mitigate a lot of the "shake" (to the extent it exists) the LS3 has at idle.

I've experienced a lot of reasonably smooth pushrod engines, while at the same time, there have been some notably rough, unrefined DOHC V6 designs. Either can be made very smooth and refined or not so depending on factors having nothing to do with where their cams are placed.

If GM feels it needs both a V8 and DOHC to be competitive in all its various segments, why not build a DOHC V8 like Toyota, Nissan, Ford, Hyundai, Mercedes, and Audi all do. Wouldn't one engine be more cost effective than 2? Don't get me wrong, I love GM's pushrod V8s (as they do have certain advantages over DOHC), but I am still just as happy overall with my DOHC one, too.

Well, GM did make DOHC V8s for many years (i.e., the Northstar line in Cadillacs, as well as a few Oldsmobiles & Buicks). For whatever reasons, the Northstar program was ditched.

Of course, one of the best DOHC V8s that GM ever sold was the one in the 1990ish Corvette ZR1. That engine was assembled by Mercury Marine rather than GM, though.

Bottom line... at this point in time in the GM world, it's a DOHC V6 or a pushrod V8. Take your pick.

With the push toward fuel economy, it wouldn't surprise me if GM never sold another DOHC V8. But who knows...

They did. The Northstar V8 line was an OHC family of engines, but GM cut it in 2010. The point that I'm trying to get across is that if you want to get 400+ HP out of a small block, it won't be as smooth as a DOHC V6 with turbos. Plus, the snobby import drivers wouldn't want to drive around with pushrods under the hood. If you look at the CTS segment, you see that the top models are all powered by turbo 6 cylinders. Caddy followed the rest of the segment, and blew them away with an excellent engine.

Yes, it is inherently hard to balance a 60* V6 than a 90* V8. Luxury car companies just puts a lot of money into reducing the vibrations...money GM is just starting to invest. It will always be more expensive to get the V6 to run as smoothly as the V8, push-rod or not. With new technologies for block casting, piston/rod production, we are seeing some of that cost offset in other areas when there are fewer cylinders. I-6 engines, however, do balance very easily.
