I found that :

A-Real world, it's a decent gap in MPG. I took both cars and ran them on the same loop to compare, not 100% scientific but pretty close. I got 35.5 in the N55(8at) and 39 in the N20(6mt). I am pretty sure an N55 6mt might get a bit less than an 8at.
B-The power difference is not as large as advertised, both engines underrated, the 328 just more so. This has been shown on the dyno a handful of times.
