    Based on this morning's Z06 reveal...

    ...which says customers won't get cars until "early next year" I'd say anyone looking to buy a V3 is in for a long wait.

    The eight-speed auto "about 4 kilograms lighter than the six speed" was an interesting tidbit, as was a smaller but faster-spinning blower than the LS9. Of course, some V2 owners already have experience with faster-spinning blowers...

    ---
    So settle in, boys and girls, it looks like V2 is still top of the Cadillac performance heap for another year or so.

    I think "lighter" is going to be a major theme at GM. Note its kilograms not pounds. I heard engineering has been directed to measure in grams. Amazing they cound shave off ~10lbs and add 2 gears.

    Probably going to be the same LT4 around 600 hp.

    Over on gminsidenews they're saying the LT4 is the V3 powerplant.

    Re: Based on this morning's Z06 reveal...

    I'm totally down with that. It's pretty much exactly as I speculated months ago, a supercharged version of the new LT1 with all the new goodies - direct injection, cylinder deactivation, variable valve timing. I'm actually really happy about that, it gives the V3 a fighting chance to get some halfway decent MPG, especially if they make the C7's 7-speed manual available for it. Or the upcoming 8-speed auto too. And if they give it the same modes the C7 has, like the eco mode that uses the cylinder deactivation, you really will be able to use it as a halfway decent MPG daily driver, assuming you have the willpower to keep it in eco mode for your commute.

    Now all we need to know is how much it will weigh, and how they're going to solve the traction issues.

    I hope they (GM) don't get carbon build up on the intake valves like Audi, BWM, and Mercedes has with their DI engines. Audi has been really bad about it too, they really don't want to clean them under warranty. Thats why I switched over from Audi. They have not yet shown to fix it and they were dicks about covering the costs of the cleaning.

    Re: Based on this morning's Z06 reveal...

    DCV -- that's really really old news. Audi was an early adopter, and everyone has learned to deal with it since then. Some add an injector upstream, others tweak valve timing. The idea is to get some burn on the top side of the valves to burn the carbon off. Of course there will always be individual stories of buildup -- heck, it happened before direct injection -- but it's not a big deal.

    As for the V3 transmissions, I would be shocked if we didn't get basically the same 7-speed manual and 8-speed automatic as the Z06.

    As for the engine... I'm not sure GM will feel the need to give the car 625hp/635tq, especially since they've kept the weight off the base chassis. I know folks here feel differently, but it's GM's decision and they often skew conservative.

    As an example look no further than this new LT4. Impressive, sure, but it's less hp than the LS9, and less hp than the Viper. We all know how horsepower-obsessed some folks can be. It's interesting that GM chose to pull up short of that number. It's a harder sell. It makes me think they might do the same for the V3. Maybe V3 doesn't get titanium intake valves and doesn't rev quite as high, or maybe the blower doesn't spin quite as fast, because GM figures they can get buy with slightly less cost (including warranty cost) and still have enough power to put up good track numbers and sell cars. Maybe they even hold the LT4 for a CTS-Vplus that extorts an extra $7300 out of buyers. After all, that's what BMW and Mercedes do.

    So does anyone have any intelligence on how GM deals with carbon buildup on the LT1/4 emgines, and how effective it has been in pre-production testing?

    Their current 2.0 turbo 4 still has the problem.........

    Re: Based on this morning's Z06 reveal...

    From the "Gen 5 Small Block Lubrication System" news release last year:


    PCV-integrated rocker covers
    One of the most distinctive features of the all-new Gen 5 engine is its domed rocker covers, which house a patent-pending integrated positive crankcase ventilation (PCV) system that enhances oil economy and oil life, while reducing oil consumption. It also contributes to low emissions for the Gen 5.

    The rocker covers also hold the direct-mount ignition coils for the coil-near-plug ignition system. Between the individual coil packs, the domed sections of the covers contain baffles that separate oil and air from the crankcase gases – about three times the oil/air separation capability of previous engines. Each cover features an inlet and outlet path for the crankcase gases, with the separated oil dropping back onto the engine within the covers and the remaining air/gases circulated back into air intake stream for combustion. The system also prevents moisture from accumulating in the engine.

    This integrated PCV system is an essential contributor of the Gen 5’s efficient performance and long-term durability – and the domes for it on the rocker covers make the Gen 5 engine instantly recognizable.

    I thought port injected engines had less of an issue because the valves get bathed in fuel and detergents.

    Am I missing something?

    Edit:

    Scratch that. It's a DI engine.

    I have to say it again, they hit it out of the park with the C7. Beautiful car.

    Sounds like the valve coves are in essence a catch can. Good idea hope it works.

    No need for a dual clutch when the 8L90 slated for the Z06 is reported to be faster shifting than the PDK.
