Car and Driver Magazine used to do really good tests on new cars... maybe they did one on these .....

They may not be very different in actual times.. it may be the feeling ... and the gearing possibilities when needing to get some more umph at certain speeds which is restricted in the auto... as compared to downshifting to pass in the intermediate ranges... like between 20 and 40...

I know most of you don't really have that old " two lane road, farm implement in front of you, short passing distance availble " situations very often... not like in the old days when most roads were two lane.....

Standing start, with pedal floored , the auto and manual may be very close 0 to 60 or quarter mile or whatever....
