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.

That's not how these decisions are made. Competition models are typically not noticeably faster than the base models anyway. They wouldn't handicap the pure model that much just because of some concern about relative performance, and especially not ring times. The awd 8pseed version would be faster in most performance metrics anyway.
It's either a durability/compatibility issue, a cost issue, or they are trying to limit 6mt's to prepare us for a complete phase out next generation.
