Not only downshift but the main advantage of having closely spaced gears will give you FASTER ACCELERATION.
And that is what I and some other spirited car enthusiasts are after. So fuel economy isn't the only thing that is benefited. Faster acceleration, better deceleration, and better fuel economy.
No, the E92 M3 is not faster than the IS-F in straight line accelerations. IS-F is a bit faster. For the M3 you kinda gotta give it a bit of time to pickup rpm to get the power you need whereas the IS-F picks up power immediately after each shift due to more tq and closer gears. Close gears are extremely important for fast accelerations. If the IS-F had 6 speed taller gears it will go slower, and will be considerably slower than the JB3 chipped 335i from roll race. Basically, the short gears are saving IS-F's a$$.. gotta thank the wonderful gearing.

in the m3 if i shift right at the redline to the next gear, it will right be around 4rpm and the power is fully there to continue to pull, i don't feel the need to "wait" for the power to come back up. of course if i shift early and keep the rpm around 2k then it's another story. but that's about how the car is designed and driven. i don't doubt the c63 and isf are "easier" car to drive in normal condition, but given how the m cars have been designed traditionally, more gears might help on the m with that high rev redline.
with that said, if they go with tt v8 for the next m5, the characteristic will be a lot different (more low end tq and probably not as high rev). in that case then gearing might play a different role

I have driven the M6 and although its fast it doesnt feel like it has 500hp because of the insane weight. It was a thrill to drive and it made an awesome noise but it just didnt blow me away. I expected brutal acceleration

Have you driven the 2010 550i GT hatchback/wagon, with its twin-turbo V8, 450 ft-lbs. of torque, and 8-speed automatic? (see my recent review, in early December) Yes, it also is heavy, but, even so, trust me......it will DEFINITELY get out of its own way
It's doubtful, though, whether this car will be as fast as the new M5.

Ring vid
As promised, here is a vid of the upcoming M5 on the Ring. At 3:38, there is some rocking going on the incline. Manual tranny perhaps?
Enjoy!
