That power loss is actually at the fly where the power is qouted..the actual losses through the auto box are a lot more...the car is over a second slower to 60 and 10mph top end...you do have 60:40 torque split to the rear but the manual is 50:50
Power is qouted at the flywheel, therefore, before any transmission losses. Auto's have a smaller turbo, that spools up a little sooner, but lack's the ability to flow at top end.
