No, it's not aimed at the X6M. No one buys an X6M to be driven around by someone else.
Chinese businessmen are the first target, but in the US there are no real "direct" competitors at the price point and in the "SUV" class. The Escalade and Range Rover LWB Supercharged don't have an executive seating package as far as I know. The Autiobiography versions of the RR offer this, but they are closer to the $150,000 and $200,000 price point. BMW's new X7 may be a direct competitor, especially if an activehybrid is offered.
Then there are chauffeur-worthy sedans. The Lexus LS 600h L has the closest powertrain among vehicles commonly chosen for this purpose, but it will cost closer to $130k. You have to "go big" to get the executive seating package in the A8 L - it's only offered with the W12 and that will run you $140k at minimum. The MB S550 can be had for around $100K with the executive seating package, but you can take that to nearly $200K with the V12 and Maybach versions. The new 7-series offers this kind of rear seating at under $100K though - you can have a 740i so equipped at around $100k out the door.
Then there's the top of the line. The Rolls Royce Phantom is well over $400K, I don't even know what the EWB version costs. And the Bentley Continental Flying Spur W12 Mulliner is... I don't know how much those cost, either. But it is worth noting that Volvo isn't really competing as much for the old money folks. Many of them are happy riding around in their classic Rolls and Bentley's which show off family legacy and aren't just about having the nicest and newest things in life.
Edit: Also realize that these vehicles are not always purchased by private individuals. They're often leased by businesses as security vehicles, driven by corporate security rather than a chauffeur, and used to get high level executives from one meeting to the next. The Maybach, RR SVAutobio, Rolls Royce, and Bentley might fly for a private with loads of money to spend, but the more affordable options are usually chosen when there's a corporate board to keep happy.
