Mein Auto: '13 BMW 535i M Sport
I'm curious about this as well. I posted in the F12 Forum the question of what the N55HP has that's different from the N55 that gives it that little extra boost in power.

What I'm really curious about is how much REAL power it has over the N55, as the N55 is very underrated (at 280 RWHP putting it around 330-340 actual crank HP).
