took my x5 4.8 to a an empty deserted road to check it full speed
the head up display gave me and accurate 252km/h which is actually faster then what the official site says:P
and went head to haed with a cayyene S in a drag race won 3 times lost the 4th cause he did an old school launch control
and then went head on with a range rover super charged he actually beat me every time;s which is akward cause im suppoused to be faster
