Could be true regarding the fitment, but I never heard that before. Always heard it was down to cost.
Don't the N55 and N20 sit right up against the firewall? I thought the N55 just extended farther forward?
Regarding the gearing...
The rest of the N55 cars got the 8 speed. Technically speaking, it doesn't matter where the power falls off, a gearing advantage is a gearing advantage.
I'd be interested to see where you read that.
I'd be more inclined to believe it if they just said fitment, the second they blatantly lie about gearing, I'd question it all.
The car is all E90 xdrive underneath, what makes that trans not in the X1? But it fits in the 2series?
