My two cents, is in this case the two vehicles are likely comparable in handling due to the fact that the 5 series is a non-sport with softer springs and more body roll. The comparable is that the X6 even with all of its advanced technology aids and sport like suspension, is still significantly heavier and higher center of gravity so take a tighter corner going in and out, the X6 will be slowing more to stay in control, whereas the 5 being a rear drive only can also sweep the corner like drifting if necessary. The X6 is AWD which does help with grip but also limits the speed in and out of the turn.
I would bet with two experts driving the 5 would have a slight advantage in handling alone but there is also the big difference of horsepower/torque so to contradict my earlier statement, unless the roadway is mostly turns and not much straightaways or not many long turns, the X6 could potentially keep the lead. Obviously various roadways would have various outcomes. How about someone call Top Gear and get them to compare on their test track

F centrifugal = 1/2 * m*v^2. His mass is 2.265 tons. My mass is 1.575 tons. His mass is 44% higher than my mass so he has 44% centrifugal force acting on his car. Can the technology offset the 44%? I don't think so.
Having also looked at your picture of the corner in question, I'm absolutely confident that the X6 50i will be able to take the corner faster than you.

To a great extent, yes it absolutely can. He's also putting much more rubber on the road than you, you'll have a much smaller contact patch and the PS2s you're running aren't the grippiest tire to begin with. Add the body roll from a non-sport suspension into the mix and you'd be surprised just how much technology can offset. BMW's chassis and handling engineers threw pretty much everything they know at the X6/X6M, yours by comparison is nowhere near as sophisticated.
And for the body roll it is not that significat. My car will have a maximum roll of 20 degrees, and if you follow this link http://www.autozine.org/technical_school/h...eight-Body-roll you will find that the weight distrbution is not as significant as you think it is. It will be much more significant to his car due to the extermely high CG, but not to my 5er due to the much lower CG.
Why is it then that the 530i is much faster on the Autozeitug track (link below) than the X6 x50i although the X6 will eat it alive in a straight ?

For the E60: lower weight and lower center of gravity.
For the X6: more power, more traction, torque vectoring.
Close call, depending on how much of the course is straight line and curve.
Why not duke it out at a road course track?

Please be safe in this test and report the results after you do your face off. Will your friend let you swap vehicles and do the test in each others vehicles? That would be a good way for each of you to test their skill against the vehicle. Will be interested in results.

As others have said, just go have the race and report back with video evidence. We'll see who was right!

my previous car was E70 X5 3.0Si Sport, now I run an 2008 E60 525i Sport.
The E60 holds corners way better then my eX5'er although I miss the size... The 5'er is so much smaller and lighter.
The only time I will move back to the X's is either the 4.8i engine or the 3.0d chip tuned! Or just jump to the ///M X5 but that will send me a penny back in care costs... If only ///M-Powered BMW's would be sold with 2 sets of tires for free I would burn so much rubber..
*runs outside the house and checks his summer wheels, rear tires like almost gone 11,XXX Km on the speedometer darn love burning rubber... thats only a 525i Sport if the engine was 550i my tires would be gone around 5000K
