Why wouldn't they be competitive, they're used in drag racing all the time. Once the torque convertor locks up your in direct drive. Top speed is the result of how much horsepower you have.

I think that for top end speed, an M6 would be best since less power is lost going through the drive train. An A6 will rob more power than an M6. I agree there is no reason you couldn't be competitive with an A6, however, a lot of those at the TX Mile are shooting for 200MPH and putting that kind of power through an A6 would be difficult compared to putting it through an M6.

NO... thats why they have the auto stick coming out of the floor, why not put push buttons on the dash and save the room/weight?

Top speed takes Horsepower, the Auto trans in the 'Vette takes about 10 horsepower to pump all that fluid around.
Look at Dyno differences between Manual and Auto transmissions, with a C6 it's around 10 HP.

And it takes just about the same 10 HP to pull an outside mirror 200 MPH.

Manual or Auto 150 is easy, 180 is tuff and possible with enuf room. At 180-185 there is this wall that takes alot of HP to get past,,,,,200?? thats tuff and will take a little Forced induction or NOS. thats just my take tho
