Well if and more then likely there will be a V6 5th Gen any idea on what engine GM will plan for it? I have heard rumors that GM is gona stop use of the 3800 II engine so what would they use in place? As far as im concernd that was really there only decent V6 engine.

 

I think the 3.8L seriies II is already done being used(or is being phased out) for the new 3.8L series III

the L67 is already gone, been replaced by the L32(which is a 3.8L, I know confusing thats the same code for the 3.4L in early f-boodies)

Its possible the 5th gen may recieve some of hte new motors in the colorodos.

 

The 5 cylinders?

 

sure why not... I didn't read it anywhere but seems to be the easiest motor to adapt since its already RWD

 

It is too tall for a car.

I'd like to see a HF 3.2L DOHC V6 256HP+. the 3.9L HV V6 MPG #'s don't impress me, although seen the mpg #'s when mated with a 6 speed yet.

 

Yeah, that would be a great engine for a base model. It would give the base a much sportier feeling to it. How likely this scenario is though, remains to be seen. Somehow I doubt it.

How much more does it cost to build the DOHC 3.2 over the pushrod 3.9?

 

I'd put the 3.9L or some derrivative in it if it were up to me.

 

Unless GM designs a new 60degree V6 I am betting pretty much on a maybe 255hp 3.9 V6 vvt and possibly DOD with a 6 speed auto and 6 speed manual available.

I really doubt we'll see a DOHC v6 in a camaro anytime soon unless there is major thought change at GM also I wouldnt slack on the pushrod V6's yet GM seems to finally putting some attention in them..........

Though the 60degree V6's have always sound good so when some wants a louder exhaust it should have a decent growl to it. If you cant afford the V8 or the car is for someone who don't need one lol. I say a 3.9 v6 would be a good choice.

 

I don't understand the cost issue when looking at OHC and OHV engines.
Other manufactiures have no problem going with all OHC.

And.....

All Cobalts are OHC--so I am puzzled here...

On another note, I rented a CTS last weekend. It had the 2.8L 210hp. Very smooth, loud when you hit the peddle and it had some get up and go. Good for a base engine for the CTS....

 

3.9L 240+hp sounds good to me, if the 5th weighs in like the 4th, that should put the standard Camaro in the mid 6 second range to 60 mph

Also NO plastic wheel covers for the standard 5th gen.

 

One way to look at it is that business (like engineering, as PacerX might say) is all about using the least amount of material & complexity to do the most work using the least amount of energy at the lowest possible cost.


GM's pushrod V8 vs Ford's "Cammers".

Ford's engines are way more expensive to make, use more fuel per cubic inch (higher revs), and are bigger and harder to package (your jaw would drop off if you saw Ford's DOHC 4.6 next to an LS2). Sure, they make more horsepower per cubic inch, but all that becomes ridiculous if you use more fuel, material, and cost to get there. Even Chrysler, which created their own "cammer" over a decade ago, went back to pushrods for their new "Hemi" engines.

In smaller engines, high revving OHCs make more sense. A 2.2 4 cylinder with OHC would require a much bigger 4 to make the same power, and then you get into engine harshness (few but large pistons mean more vibration) and alot of other issues other people here are more qualified to explain than I am. Ditto V6s.

 

Yes, you right. I remember reading an article along the same lines as what your saying. I like GMs LS1 series V8s---but think there HF DOHC V6s are excellent and should be applied more.

 

What would be kinda neat is taking the 3.9 up to 4.2 or 4.4 via crank stroke. Just make it a torque monster. Make it "feel" fast and capable in traffic. Plus using cubes to make torque is usually more fuel friendly then spinning RPMs to make horsepower.

The reason I skipped 4.3 was so some hicks wouldnt just say "They puttin thuh 4.3 in em now"

 

An overhead cam engine in a Camaro..

How times have changed

 

I think a v6 Camaro should sound something like the Grand Prixs do. Evertime I hear a Grand Prix with a decent exhaust on it go by, I am always amazed that a v6 can sound that decent. Slap an exhaust on a 4th gen v6 Camaro, and it sounds decent at idle, but quite awful when you rev it. I think it would be great to give a v6 Camaro a good tone to it.


Why not? The Mustangs do it in their v6s, and GM seems to be emulating the new Mustang on many fronts, so I can't see camshaft placement being that important. As long as the engine runs well, and feels sporty, the non-enthusiast is not really going to care what kind of valvetrain their car's engine has. Besides, how may enthusiasts actually consider the v6 Camaro a real Camaro? They are more than likely not going to care what kind of engine goes in there anyway.
