The Z06 has a clearly superior power to weight but the DCT does add quite some real effective hp to the M5 from a performance perspective. We have seen the exact same effect in the M3 DCT vs. MT. In a stock M3 the DCT is probably good for 20-50 effective hp depending on the contest (much discussion and validation on this if you do not believe it right here on this forum). Also the German Sport Auto magazine found the two cars nearly neck to neck in a drag race. I think the video is reasonable.

It's funny. I see some of you impressed with the Z06 (as was I) and a bunch of others simply making excuses for it. You would all make great lawyers because apparently video lies. lol
Pumping the sound of a V8 through the speakers is still lame though. |

Absolutely. BMW blew it pretty bad on this point. It does not matter if it is real engine sounds, synthesized ones, intake sound or not. Whatever they've done is completely lame...

Maybe I'm missing something, but how hard is it to push the pedal to the floor and drive in a straight line from a rolling start with a DCT car?

I am not sure if the F10 M5 had the DSC disabled. That is an absolute must. If you simply put pedal to the metal with DSC On, the sheer amount of torque would render the power useless and light up the dash with the DSC light. Even with MDM, u still can't deploy the full power. DSC Off is a must in any drag race for the new M5.

The Z06 driver could definitely have shifted better, but it wouldn't have made too much of a difference. Remember, the Z06 only makes 505 crank, while the F10 is supposed to make (at least) 560. From a 50kph roll, torque and power-to-weight make a substantially smaller difference.

That is incorrect. At any given speed (all speeds...) power to weight determines acceleration. The car that makes more power to weight will accelerate harder. There are some minor corrections to this for losses, gear inertia, etc. but power to weight it all that matters. As stated prior in a battle involving a wide range of speeds and shifts shift time is also a very significant factor. Torque is mostly meaningless. This topic has been discussed and debated time and time again here on the forum and the conclusion is always the same.

Gotcha. Keep in mind that power to weight still matters when accelerating at high speeds, it is just that ultimate top speed is purely limited by power and drag but not weight. Torque at the crank is also a meaningless quantity. Gear ratio must be involved to make a physically meaningful quantity. I think part of the reason folks believe torque matters at low speeds is sort of an artifact. The power can be higher at lower rpms at and right after launch in a typical high torque low power engine (say Vette vs. M3). Either way its still actually about power to weight . Cheers.

Dat V10.
I will ALWAYS prefer the E60 because of the glorious S85. Don't care how fast the F10 is.

Agreed, a properly driven C6 Z06, should outrun a stock F10 M5.

Not a fan of the new M5 either, just the sound of the V10 in the E60 was enough to make that car the obvious choice for me, rather have a high revving V10 that screams than a muted V8TT. |

Otherwise, as it said in a "Murphy's Law" poster on my office wall: "The battle may not always go to the strong, nor the race to the swift - - but that's the way to bet." Horsepower wins races. Bruce Edit: PS - In this case the lightning shifts in the M5 are contrasted with what seems to be painfully slow shifting by the Z06 pilot, allowing the M5 to hold its own or even pull on the Vette.

And for the rest of the conversation, horsepower and torque are the SAME THING. They are just different words for force. HP= torque x rpm/5250. You can have horsepower by having more torque ie: c63's or by rpm's ie: Honda motors, but at the end of the day it's all just force.
