Can't find any info on this, but I've read that GM was to hold a Press Conference in Detroit today to release further details of the Gen V.
I can't find anything on the web, but there you go guys, what can you find out?

Nothing yet, but its still quite early in Detroit (3am). Cant find anything in a search either.
Something for you to read while your waiting .

Juicy details out now: http://www.digitalcorvettes.com/foru....php?p=1993096
More grunt down low will be nice.

The next generation Corvette engine is the Gen V LT1, which is a direct injected V8. There was a ton of speculation about the displacement, with early reports placing it at 5.5 liters, like the C6R race car. This morning, GM has confirmed that the LT1 will be a 6.2 liter engine.
It also gets some advanced tech. The LT1 has cylinder deactivation to increase fuel mileage, which is reportedly more than 26 MPG on the highway, direct injection, dry sump lubrication (which will be an optional extra), and variable valve timing.
While more efficient, the LT1 is also expected to provide a nice power increase over the current LS3. With at least 450 horsepower and 450 pound feet of torque, the LT1 is up 20 horsepower and 26 pound feet of torque. It actually has a slightly better power curve than the might LS7 that currently powers the Corvette Z06.

So,......335KW & 610NM......not bad for a start.....I guess that will be HSV's new "standard" engine.
I wonder what the "high performance" varieties, if any, will be, & how this affects production & use of the supercharged LSA & LS9?
Cheers, Pickles.
I hope we see the return of the hero GTS with say the LSA, and the rest of the range with the 335kw Gen 5... Doubt it will happen, but the GTS back in the VX days was really something special having the 300kw C4B over the 255kw LS1. More than just fancy wheels and suspension. And the late 325kw GTS would have convinced no one that it was faster than the 317 badged lower spec models...
Very nice. Look forward to see what they can really do

Interesting that they are pushing ahead with the DoD system.
Makes it sound like they are making an effort I suppose. :lol:Quote:

yeah I thought they looked like oil squirters, good to see they have caught up with the RB25 :P
I can't wait to get the DoD liters out of my engine, terrible ticking things they are.
some video's shown have alot of ppl wondering if there could be a twin turbo model:

Turbo....IMHO, the answer to that is ...NO.Quote:

They just love using the same engine designations over and over don't they?
Looks like a V6 in that video anyway..... could mean a TTV6 also that video was from 2008.
Doesn't really look good for forced induction either way, compression is too high for factory fitted F/I.
I'm still hoping for a C6-R type 5.5l F/I, not that i'm chasing supreme power but a more up to date way of delivering the power, move with the rest of the field.
yeah i wouldnt mind if they didnt come out with a turbo or supercharger etc cause most of the time ppl upgrade them to big and better anyway. as long as this gen V LT1 is as good as it looks then hopefully may see it in the commy's.
i think the VF will be like the Ve models when they first came out, hsv still had the Ls2 then a year or so later just before S2 they started putting Ls3's in them.
May even see an LSA in the hsv and the LT1 in the SS if were lucky, who knows really...
yeah few ppl now saying that it could be the V6 tt.
I was told that the reason holden used the LS2 then the LS3 was that they had heaps of LS2's left over and basically got rid of the stock before updating to the LS3.Quote:

Wonder if the uncrackable ECU I've been hearing about will be a reality, that would make things difficult for those of us who cant stand anything standard.
Nissan said the same thing with the R35 GTR and if I remember right it took about 2 weeks after people got there hands on them before a programer cracked its brains open.Quote:

Cheers, Pickles.
haha I was gonna say, I remember in the mags the engineers going on about the ECU was "uncrackable"Quote:

I can understand the reasoning for doing so, with warranty claims and emmisions, but if the owner is willing to take the risk and void warranty, then fair game.
I think you may be right, the OEMs often underestimate the capability of the aftermarket guys.Quote:

Slightly OT but I hope they've been working on a DSG 'box. Going from driving a 2012 SS Camaro to a 2011 Golf wagon really highlighted to me how bloody good those DSG boxes are!
this is a bit more info

I can't believe the LT1 is still using a pushrod design. An all new engine that utilises dinosaur technology... And it is AFM equipped, because performance and AFM has been so great in the past.... Im pretty disappointed.
On the plus side, It definitely makes owning a 6L GenIV feel like your not missing out on anything new! So I guess that's good?
well dragster engines and some of the bigester hp stuff still use IT so it cant be that bad LOL
Yeah I know. It's proven to make big power. But when you have Porsche, BMW and Mercedes making V8s that seem to defy physics by propelling their cars to new limits without using pushrods, you'd hope a brand new design from GM might have some similarities... Or at least show some signs of being an engine built with technology that wasn't first used pre 2000...Quote:

Continuous VVT and direct injection are quite a large step forwardQuote:

Also note the test date, March 2008.
GM Gen V 6.2L V8 as fitted to the C7: 335Kw and 600Nm, push rod, 2 valves per cylinder.Quote:

Yes, I know the AMG comes in higher states of tune for the E63, 386Kw and 700Nm, but this Gen V is simply the initial base engine, have no doubt that tuned up versions will offer much more. The fact is GM should stick with the pushrod design, it is cheap, dependable and money can be spent on improving other things, such as combustion chamber design, manifolds, variable valve timing, direct injection, piston coolers etc.
I just hope the engine mounts and transmission bolt pattern is the same as the Gen III and Gen IV. Hello retro-fit!!!

Strange thought that the devolpment for an engine made here was being tested by GM USA, could it be the TT 3.6l V6 we've been waiting for since the Torana concept?Quote:

That's a parameter readout box for water flow in litres per minute, not a description on which car they are testing, all the descriptions are at the bottom of the screen.Quote:

I think maybe I was expecting too much.
I still cant believe people don't get it....Quote:

Thats a bit like saying "The reject shop should get better products in and charge more for them, then it would be a better shop". Well the truth is they have a target audience in mind, changing to a more expensive product means their competing for a different customer against the much bigger players.
I think the Gen V has achieved everything it needs to be to be successful in the market its competing in. Comparing it to engine 2-3 times the price is just, well, pointless.
So if Ford can do it, why can't GM? I don't see their prices being any higher than GMs... FPV offer a supercharger and a quadcam V8 for a fair amount less than HSV offers their "cheap push rod technology"...Quote:
