Saw a black E70 X5 driving north on 395 yesterday but noticed the lower end of the spoiler was disguised...unfortunately, I was on a section of the 395 which the highway was divided. It was going pretty fast and by the time I realized what it was I didn't get a good look at the rear end to see the tailpipes.

Just curious, what are the rumors re: "iS" version of the E70 X5....twin-turbo V8 or twin-turbo V10?
