Imagine the 6MT version close to 100Kg lighter with less drivetrain drag...it will kill the X Drive version in ultimate performance. This means they will push people to go back to 6MT for higher performance and they don't want that.
That is the main reason they reduced engine power on the Pure version.

I think this makes sense, especially if BMW is thinking about Ring lap times, it was possible Pure was too close or even better than the Base in testing with equivalent HP (being lighter and less power loss). Thus they detuned the engine to keep the hierarchy.
It's just too bad the power gap between Pure and Competition is so large (~60hp).
As an aside, I wonder if the detuned engine (assuming they don't make it any structurally weaker) will be much more reliable. Not that BMW engines commonly break anyways (usually water pumps, turbos, rubber/plastic, etc.)
