The BBJ 777X is based on the new Boeing 777X airliner.
Like the commercial airliner on which it is based, the BBJ 777X will be available in both 777-8 and the larger 777-9 variants.
The BBJ 777-8 has a range of 13,400 miles while the larger BBJ 777-9 can go up 12,700 miles. That's several thousand miles further than the airliner versions of the planes can fly.
In fact, the BBJ 777X is the longest range private jet ever made. That means flights from Sydney to London or Seattle to Dubai are possible.
Power comes from GE's massive GE9X engine that returns 5% lower fuel consumption than rival powerplants while producing 29% lower emissions.
The 777X boasts a 236-foot wingspan along with a cabin that's 7.9 feet tall and nearly 20-feet wide.
The 777-9 is 33 feet longer than the 777-8 and as a result, has more room. The 777-8 boasts 3,256 square feet of interior space while the 777-9 has 3,689 square feet. That's about as much interior space as a large suburban home. A very luxurious suburban home.

BBJ did not say how much the custom interiors would cost, but it's safe to say it's in the hundreds of millions of dollars.
The Boeing 777-8 has a list price of $394.9 million. The larger 777-9 costs $425.8 million.
The Boeing 777-9 is expected to enter service in 2020 and the 777-8 is expected to follow soon after.
