I noticed that too, and it surprised me much more than the transmission gear ratios being the same. The latter is pretty common for cars with different engines (see E9x 335i and E9x M3 for example), but typically the final drive is used as the equalizer. I guess the N20 and N55 are similar enough in power delivery that they can use the exact same ratios from the engine to the wheels. What's interesting though, is that for the manual transmission, everything is different. Even the transmission itself is totally different between the two (not even the same manufacturer, apparently). Seems a little strange given how similar the respective AT-equipped cars are.
