We are on our 3rd x5 (1st F15), all have been V-8's. When deciding on the F15, we drove the V-8 for a weekend. Was curious about the 6, so we drove it, didn't make it out of the parking lot, my wife commented, "this feels like an x3" (we have had a few). The extra 2 cylinders are just much smoother. Power, exhaust note, and options that come with the 8, as others have mentioned, are icing on the cake. No hate on the 6, it's a great engine, just what worked for us.
