New Engines Drive Change From Falcon 5X to 6X
Once it had taken the decision to swap Silvercrest for PW800s, it didn’t take long for Dassault to define the 6X.

When Dassault decided late last year to drop Safran's Silvercrest engine that had already delayed its Falcon 5X by three years (the actual engine delay was four years), the obvious replacement choice was the PW800. However, the higher thrust range would necessitate a redesign, and for this reason, among others, the company decided to ditch the 5X name and “relaunch” the Falcon 6X. Dassault made the announcement in late February and followed up with a technical briefing on March 8.
