Some grossly exaggerate figures, or round off. It's not always a game of crank vs. rwhp in consideration to driveline loss. NA engines seem to be the least on target with marketing departments. But fine by me as I'm not looking for the highest number for some sort of bragging rights. The power is adequate, and more power comes at the expense of fuel and reliability.

Whatever the power is of the 981 S it's more than enough, especially considering where you drive it. I lived in Germany through 2009 and there power mattered a bit. In the US, not so much. I can't keep my wheels from spinning with the power I have now in the lower gears and not even under max acceleration. Why would I want more?
