The Global Express XRS (which has now been renamed the Global 6000), which has a range of 6200nm. The G550, the other competitor, has a range of 5800nm.

The Gulfstream G650 will have a range of 7000 nm at Mach 0.85, and 5000 nm at Mach 0.90.
I think that as you get much further than the G650 the planes will have to get bigger. And not just bigger in the "bigger planes fly farther" engineering sense. In order to be usable for missions approaching 16-18 hours people are going to need more cabin space and amenities. Things like actual beds as opposed to divans and onboard showers are going to become necessary along with more space to make such flights practical. Plus the potential for additional crew, space for more provisions, etc. It can be done, but it's just a matter of how much it would cost and how many people are willing to pay for it.

Well if you look at the price tags on the aircraft Wingscrubber posted, it starts making sense or cents why a used but nice 757 starts looking much more economical.
You would probably leave the gold plated equipment that Trump installed behind but cost wise that would make a used 57 with about a million or so for interior furnishings, beds and showers look viable.

Yes and no. It's cheaper to buy, really most used airliners would be. But it will cost more to operate and does not have the same performance as a Gulfstream or Global Express. Maintenance for older airframes is probably going to be an issue as well.

I don't think folks who haven't spent several hours on a biz-jet realize how confining and limiting the cabins are for really long flights.
Remember these cabins are not bigger than a CRJ. If you are making a 6 to 8 hour trip with three pilots, an FA and two primaries - that is okay.
If you are making a 12-14 hour trip with three pilots, an FA and five primaries - the airplane is crowded and not terribly easy to move around, to get up and stretch, etc.
The company I used to work for bought a G-550 partially for the justification that they could fly from the midwest to Shanghai. After a couple non-stop trips, they have now standardized on a tech stop at Anchorage. Just a 30-45 minute stop, but enough time to stretch their legs and work out the kinks.

Quoting 26point2 (Reply 9): A Boeing or Airbus product can't operate to/from KTEB which is a deal breaker for most....
I'm not sure it's as big a deal breaker for as many people as you'd think. TEB is not the only airport for the New York area and there are significant numbers of BBJs and other airliner based designs in corporate use. Not as many as Gulfstreams or Global Expresses, but still significant.
The TEB issue is further trivialized by the rise of charter and fractional operations. If you really, really must fly to TEB then you just book a smaller plane. For other trips, use something bigger and more comfortable.

You can fit the thing out however you like, but eventually it's still hours in a smallish space. I do wonder how a larger business jet might do in the marketplace. Use new engines, give it more range than the G650, and make it larger. Say split the difference between a G650 and BBJ in terms of cabin space.

Correct, those interested in this level of plane are not going to pass simply because of TEB. They will gladly take the extra few miles to depart from EWR.

Quoting corey07850 (Reply 13): Which is the market the Global 7000/8000 is after
In terms of range, yes. In terms of size, the cabin of the Global 7000/8000 will be virtually identical to the G650. Now, that's a comfortable plane for sure, but do you really want to fly 16+ hours without an actual bed or stateroom? Or a shower, at the beginning or end of a day of doing business?
What Bombardier is doing is building a business jet that has a marginally higher weight but virtually the same size as current offerings and using the new technology to give customers more range and lower fuel burn with the new Passport engines. I wonder what the market for a plane that uses new engines to get more range out of a larger plane with approximately the same fuel burn as current planes would look like.
