It could just be my car but M550 can give X6M a run for its money 0-80. That being said, I think actual HP number may be closer to 490-500 from factory. To me, anything over 400 with AWD is more than plenty. Would I take 530HP or 453HP? Of course I would. Though, if I want to get a car in the next 5-6 months, I am not holding my breath for 2020 to come out.

It should - your M550i is lighter and even on official specs is faster 0-100kmph than the X6M.
These fast SUV's are 'fast for SUVs', but the weight, height, aerodynamics and handling mean that less powerful cars can be faster. Its not always about the raw BHP.
