I did some basic modeling on the acceleration differences between the MT and AT for the twins.
-The MT has a slight advantage over the AT through all gears. The difference in 1st gears is ~1ft/s^2 delta. This is a fairly small difference.
-It looks like shifting at redline is going to give max acceleration. Except the 4th to 5th. But, the crossover is so small I would still use redline.
-I like how the AT goes through 60mph in 2nd, unlike the manual.
-You can see the slight weight advantage (really, really small) by comparing 5th MT and 4th AT.
-No, these cars do not top out this fast. No energy losses are accounted for in this model. I think some where in the 140s would be top speed, based on the 200hp.
Added:
The time to MPH chart. It looks like the MT has a slight edge on the AT after 60mph. But, I think this is too close to claim one is really faster than the other.

Can you repeat the time to MPH chart with shift time? Aero is constant. AT and MT make roughly the same dyno amounts so drive-train loss isn't very big either.
Shift time in AT is 0.3s. Shift time in MT is driver dependent and with a regular driver is around 0.7 to 1.1s. Based on data logging at racetrack.
