200 mph X5 M

So, supposedly one of the BMW engineers in Spartanburg told a buddy of my buddy that a chipped X5 M can go up to 200 mph. I don't doubt that the X5 M is an SUV that can go really fast but 200 mph is a lofty goal even for a super car. So what say you? Is this possible or was the engineer just boasting?

Hans Stuck got an earlier X5 going pretty damn quick around the 'Ring.

My prediction?

An X5 will go over 200mph 7.2 years after monkeys fly out of my bum.

Too much aero drag, not near enough grunt even WITH a whole bag of chips.

Bring it to Ohio, Mojave or Texas mile and prove me wrong. (and I don't think you could do it at Bonneville with 7 miles of good salt.)

It'd have to be pretty close at least. They can make over 600hp with a simple tune. That's a whole lot of aero drag to fight, but I don't think its completely unreasonable.

My thoughts exactly, it's a whole lot of aero drag to overcome...

Takes ~1000hp to push a 'Cuda over 200mph, I don't see an X5 getting near that without lots more....

The drag coefficient of the X5 (.33) is lower than that of the Challenger (.35).. I don't know the frontal area but it's probably not as much more as you would think. The Challenger is pretty obese.

By comparison, a Veyron has a cd of .36 and 1100hp gets it to 256mph. So if 600hp is feasible it doesn't seem impossible that it might go 200mph..?

I'm dubious.

When I was 10 a gas station owner told me his '70 Plymouth Superbird would do 225 mph. He even pulled out the literature and showed me. I believed that for years until I discovered that what he'd shown me said that the body had been wind tunnel tested to that speed Big difference

My point is that these stories get blown out of proportion. An X5 is going to have to be modded fairly heavily to see 200mph,

I wouldn't want to be in or around one that was going 200...

Maybe it was a skunkwerks TT V-12...with a chip.
