The new C6R will be based on the body and chassis of the ZR1 and cars will be run by the factory team, as well as being available to independent teams. A 6.0-liter version of the LS7.R from the GT1 car will be used in GT2 competition next year, while the 2010 car gets a new 5.5-liter version of the production engine. Like the current GT1 car, the new GT will keep running on cellulosic E85.

The 5.5L size is likely mandated by the rules reguarding FI engines.

GM suspended R&D for its next gen V8 due to lack of fundage among other issues.

Re-read the entire sentance:

They're talking about a 5.5L version of a production engine (LS9?) to be used for 2010 GT2 competition.

They shelved the Northstar replacement...but I didn't think they totally suspended funding for the Gen V. I thought they just decreased funding.:shrug:

EDIT: Their wording was "A major part...is related to the delay of the next generation large pickup and SUV program, as well as V-8 engine development and associated capacity."

Just because they change the size of the engine, it doesn't mean it changes a generation.

I'm wondering how they would do it?

They seem to love the 3.625" stroke, but that would mean using a smaller bore than the LS1.

Maybe use the 4.8L's short 3.27" stroke with a bore in the 4.024-4.059" range?

Maybe a different stroke altogether? The classic SBC 3.48" with the LS1's 3.9" bore would be right there at the bottom of the limit.

For a Corvette, I'd like to see them keep the current 4.065" bore, but use the shorter stroke if they want to lower displacement.

Like said, the 5.5 engine is due to rules.

GM already makes the 5.3 LS4 engine.

The 3.6 DI engine is already replacing the Northstar because it's lighter and puts out the same and more horsepower (depending on which Northstar you're comparing), and is likely cheaper to make as well not to mention that it's able to be used in far more models at GM.

I fully expect the 3.6 DI to even replace the LS4 as soon as the "W" cars are retired.

The 6.2 will soon be the only V8 in General Motors passenger cars. I suspect all Cadillac "V" cars will migrate over and have one version or another of the 6.2. Outside of Cadillac, unless a car is a based on Zeta chassis or is a Corvette, you simply aren't going to see a V8 option on passenger cars GM in a few years. Front or rear drive.

Just on Zeta, have you noticed the aus currency of late? it is in the ****ter! Just a month or 2 ago we would get US$0.97 for 1 Au $, now it is down to US$0.79 for 1 Au $ and dropping fast! Holden will be pleased!

Unfortunately this has caused a problem. The dropping cost of oil combined with the dropping aus currency are basically cancelling each other out so fuel costs are staying high for us :(

PS. Holden are still selling V8s very well, if you guys stop production of V8s we are going to be pissed!!!

When I visited Australia less than 2 years ago, it was the exact opposite... and even that was shocking. :cry:

I had the chance of Australian residency back in 2000. The reason I turned it down was centered in the fact that I made more money in the US. Today, next to Australian money, I make just over half what I did in 2000, and if I had taken up residency and the job, against the US dollar I'd be making nearly double what I would have in 2000 with no change in wages! :bang:

Whats more, with the US now bailing out Fannie and Freddy to the tune of trillions of dollars over pretty much thye next decade, while we may have saved an economic Armegeddon here in the US, the move still is going to send the dollar even farther into the toilet.

We're getting to the point that it simply doesn't matter who wins the election here in November because whoever wins can't cut taxes or expand government without blowing up the economy. To be perfectly blunt about it, in general the public here in the United States is simply too ignorant to have a democracy. We're too wrapped up with the idea of getting something for free and more intrested in Britney Spears and get excited only if someone mentions the words "Gay" or making hay over a phrase "Lipstick on a pig" that we don't hold our officials accountable for what they do.

Consider that we have a record debt, and instead of finding ways to raise revenue to cover it, our congress back in 2001 voted to repeal the rule which mandated tax cuts be balenced with spending cuts and program increases be funded with reductions elsewhere. Our congress also started borrowing money from China which is retarded because now instead of simply using tax dollars to pay for what we need, we also have to pay intrest to China. Instead of raising taxes $1, we now are going to pay China $1.20, $1,50, $2 or more depending on how long we let them hold that debt.

The worst thing we've ever done was give George Bush a 2nd term. He paraded out Bin Laden to divert attention away from the economy troubles we had back then and here we are 4 years later with a basket case economy and Bin Laden still running around. Bush has never vetoed a spending bill, and it wasn't until the democrats came in last year that he started actually showing publicly any intrest in reeling in congressional spending. Talk about putting politics before the good of the country? How about 6 years of doing nothing then suddenly when the opposition comes in calling them wasteful spenders! Ugh!

The European Union has a stronger economy than the US, Canada has stronger currency than we do. The total debt of the United States of America has actually doubled... again, I emphasize TOTAL[/bv] debt of the United States..has [b]DOUBLED over the past 7 years! 8 years ago, we had a substantial budget surplus and a strong dollar.

It's hard for typical people to understand what's actually happening to the US economy unless they are actually fired. Even those of us in secure jobs are being grossly affected by the plunging dollar, yet too stupid to realize it. Every percentage the dollar drops against the world currencies equals how much of a paycut you're taking.

The United States doesn't live in a vacuum.

Right now against first world currencies in general, we're getting paid at least 1/3 less than what we were paid in 2000, and probably closer to only half. That means everyone from Canadians to Japanese get paid more than we do. Every time the dollar drops, the deficit increases. China can buy more of the US debt (and therefore influence) for the same price. Even if wages got so low that even Russian companies move here to save labor costs, as long as we still borrow instead of paying our own way and holding our elected officials responsible, we aren't going to change a thing.

Sorry for the rant, but it simply pisses me off that we've gotten into this state of affairs, there was plenty of warning, plenty of clues, and it all was ignored.... and still is! :mad:

As a closet rabid enthusiast of the Dodge Magnum SRT8, you have just made me need to go to the bathroom & clean myself up. :drool:

I have to go to the movie "Batman Begins" and steal a question from Bruce Wayne to Lucious Fox after taking a spin in the "Tumbler", the car that would become the Batmobile.........

Just speculating here, but if you look at the specs of the 5.3l, 6.0l, and 6.2l engines, the stroke stays the same at 92mm. The bore changes from 96mm to 101.6mm to 103.25mm. Logically, if the 5.5l is a truly a 'derivative' motor (as opposed to a new design, which is doubtful considering GM's current financial situation), you would expect the bore to change. A 97.8mm bore would put you comfortably in a the neighborhood of a 5.5l displacement.

I'm guessing that 'Vettes and CTS-Vs would the direct injection fuel system upgrade (similar to what can be had on up-level the 3.6l V6).
