    Torque is certainly important, and plays a bigger part in getting off the line. But power is important too, it is just not a real physical quantity like torque, you cannot really measure it and cannot feel it. Power is simply a function of torque over time. In an automotive application with gearing it is very complicated.
    I agree, the torque is what you feel when you hit the gas pedal, but power (even peak hp) is important too.

    I agree, but the point is that at 436 hp the LS3 will have more than the M3, LF-I, and the Audi RS4, yet retain a very sizeable torque advantage which should certainly help overcome any weight differences. Above 100 aerodinamics is more important than weight and the V will have a clear advantage over those cars with anywhere from 15-20 more HP, plus lets face it the LS3 (also used in the Vette and probably the new Camaro) will have plenty of room to grow with mods such as headers, etc while the prevously mentioned cars are pretty much tapped out in NA form and would need to resort to FI, which will be dificult with the very elevated compression ratios on those cars. With 6.2 Liters the V would have enormous Mod potential.
    That said I still believe the new V will probably have a supercharger, perhaps running 50 or so less horses than the Vette SS, at around 500 which will make it a current M5 and E63 killer.

    Bob Lutz says the new V is gonna suck the doors off the E60 M5. I don't think the LS3 in that trim isn't going to get that done in a V.

    I wouldn't complain if that's what shows up though.

    Real Estate is a bit slow so it looks like my '05 is going to be around for bit longer than I intended. Good thing I like the car so much!

    As far as 4? Anyone's guess is as good as mine.

    I kind of agree with you on this one. My concern is that the Z06 is pulling a lot less weight around with a much taller gear. The loads on the V with its curb weight and assuming GM keeps the 3.73 rear gears will be substantially higher. Maybe these pieces were already engineered with that in mind. Here's hoping.
