V8 6 Speed Transmission Vs V6 5 Speed

1 st gear in the 6 speed is significantly deeper than the 5 speed which is much deeper than an old style 4 speed auto.
I think the 4speed was a 3.06, the 5 speed a 3.56, and the 6speed is a 4.06.
So I would think the 6 speed would get off the line quicker(assuming that it starts off in 1st gear.)
Not too mention that second and third are deeper also.

You likely got a 2.8L 210 hp version.
I've had two of them as rental cars and my 4-500lb heavier v6 SRX will smoke the 2.8L in the CTS.
