Additionally, auto cars lose 2-5% more than manual cars. You'll never see an X-drive car put down as much power mod for mod as a RWD model, and they're also a bit heavier.

On the bright side you can launch the hell out of them and they do extremely well in adverse road conditions.
That is old information on AWD systems, you will find that newer AWD systems are actually pretty close to the RWD counterparts. I would be shocked if it was more than a 5% difference between the 2. 15 crank hp isn't going to make a significant difference. Look at the trap MPH between the 2 and you can tell the HP is very similar.
