Why the sweet taste for 5.5L displacement?

2010_5thgen

have you found weights for the 5.5? 7.0 may be lighter, but im sure its much more pricey. anly time will tell. id love to see exactly how much it weighs, and how much power it puts out, not to mention how much more efficient it will be.

2010_5thgen

why not? its working in racing....everything is about going smaller, lighter and faster...

5.5L = the rumor that just won't die.

A few things to consider...

1. Scott said the article is BS and that nothing is confirmed.

2. The Camaro is built in Oshawa, the ATS will be built at Lansing.

Therefore, I don't hold any weight that the next gen Camaro is guaranteed to be built on the same platform as the ATS (Alpha). Sure many want a "lighter" ponycar; however any speculation that Alpha is being developed for both Cadillac and Camaro is just speculation. (However I won't hold out hope that Chevrolet will get an Alpha based coupe/sedan; it just may not be called "Camaro".)

Besides, the Zeta based Camaro has been highly successful. Why mess with a good thing?

3. The DI 5.5L V8 has not even been confirmed for the production C7 Corvette.

The 5.5L displacement was developed for a racing classification. That racing series no longer requires homologation with the production displacement. Sure, back in the day, GM created the 5.0L V8 (302 cid) so Camaro could compete in Trans Am. However the displacement requirement was dropped in 1970 and the Z/28 quickly grew to 5.7L (350 cid).

I fully expect a 6.2L DI V8 in the C7 Corvette. If, and that's a big if, there is a smaller displacement V8 for the base Corvette, then 4.8L - 5.3L makes more sense than 5.5L.

Furthermore, who's to say the current generation Camaro (C5) won't get a DI V8 somewhere down the road? Its not like there's a fitment issue. Its also not like Camaro hasn't received a new V8 before Corvette did. It happened in 1967 with the original Camaro SS (350).

Just sayin'... btw... see #1 above and repeat until its fully comprehended.

I get what you're saying, but the thinking should be to make the 6th Gen Camaro a better car in every aspect. I don't think that Camaro's engineers were 100% satisfied with Zeta as a basis for the 5th Gen. Don't have any inside knowledge, that's just the feeling I get in reading the tea leaves. They did a great job with what they had though.

If you can find a way to remove a couple hundred pounds of girth from Zeta then that's fine by me. But we were kind of led to believe that wouldn't be possible. With that, I still think Alpha is the way to go, if all other things are equal.

I wish it would, I'm sick of hearing it for the past few years. I'll take an advanced 6.2 over and advanced 5.5 any day!

Agreed.

I honestly think that it was more of an issue of time and money. They didn't have the time to make Zeta lighter and meet their deadlines, and the beancounters were not willing to dump more money into Zeta in order to do so.

Now that Camaro has been so successful and GM is back on their feet in sales, perhaps the powers that be are more willing to let the engineers "play with" Zeta and try to make it a "better" platform for the next generation.

Then there's also the possibility of "two teams" each working on the next generation Camaro; one on Alpha and one on a modified Zeta platform. (For sake of argument, let's call it Zeta 3. )

I don't necessarily believe Alpha will be that much smaller and lighter than Zeta. Besides, the jury is still out on how "well" a V8 will fit. Sure GM has shoehorned a V8 into a small chassis in the past... but they certainly weren't fun to wrench on.

Personally, I like the size and driving position of the 5th gen Camaro. I'm really looking forward to my financial situation changing over the next 12 months so I can actually afford to buy one to replace my aging 4th gen.

rumors dont die until things are confirmed..... and right now, its holding a pretty solid case.

2010_5thgen

did they make g8's at the same plat as the camaro? just because the ats isnt being made at the same place as the camaro RIGHT NOW, doesnt mean things cant or wont change in 3 or however many years, when the 6th gen comes out.
and the c7 is another car that will tell us alot about the next gen camaro also, as far as the motor at least. and whos to say that they wont change the motor out the 2nd or 3rd year of production for the c7 just to keep things a little more secrative for when the 6th gen camaro comes out?

Z28Wilson

The 6.2 is the solid case. It's in production. The 5.5 "case" isn't based on anything other than a race motor that had to be that size to compete in a circuit. But we'll see.

2010_5thgen

do you mind telling me where the z06 motor originated? yes the 6.2 is obviously confirmed in the 5th gen, it is in use. but the rumor of the 5.5 can go on for as long as it wants...until factual information is released. thats the whole concept behind rumors. its also a rumor there will be a 2.0 turbo 4 clinder in the base model. until said otherwise , its a rumor. let the rumors flo! its the fun of guessing. does everyone have to be so negative Nacy all the time and so damn tight?

graham

A nascar 5.9L makes 850hp without a roller cam too but that's got no carry over to the 6th gen.

The DI technology needs to be grafted onto the already used 6.2L to not only save cost but also to not have to push a smaller displacement harder.

Id just like to know where the 5.5L stuff came from?? If I had to guess it's an ALMS rule and their 5.5L example is a 4.125x3.125 combo. Which is fine when your turning it 9K rpms

Your argument doesn't hold water. The G8s were built by Holden in Australia on Zeta. The Camaros are built in Oshawa on Zeta II (aka North American Zeta). Although related and similar, they are actually two different platforms. (Not as different as Alpha and Zeta, but different enough all the same.)

Ok so.... 6th gen Camaro in MY 2016 on Alpha with a 5.5L Gen V V8...

Sounds great. Glad its confirmed. Should give Ford a nice target the aim for.
