760hp X6M races a 560hp SLS

Comparing a SUV and a supercar is quite useless and unusual, first of all because they're two totally different cars, but if you place side by side a stock Mercedes SLS AMG and an heavily tuned BMW X6M, things could be interesting because we're talking about a stock AMG with 570hp which is going to race a big, fat //M with an incredible 760hp (that's the same power of the Zonda 760RS!).
Do you think the hp advantage is big enough for the Bimmer to humiliate the Mercedes on the straight line?
