Challenger 605 vs Falcon 6X
The Falcon 6X leads, topping 7 of 7 compared metrics.
Cross-shopping the Bombardier Aviation Challenger 605 (introduced 2006) against the Dassault Aviation Falcon 6X (introduced 2023) is a common decision, and the two sit closer on paper than the badges suggest. Both are business jets, which makes them natural cross-shopping rivals. The clearest separation between them is range, where the Falcon 6X has the advantage. We line the numbers up below, then translate them into the mission each aircraft actually wins.

Challenger 605 vs Falcon 6X: the key differences
- The Falcon 6X delivers 38% more range (Challenger 605: 4,000 nm; Falcon 6X: 5,500 nm).
- The Falcon 6X delivers 5% more cruise speed (Challenger 605: 459 kt; Falcon 6X: 480 kt).
- The Falcon 6X delivers 33% more passenger capacity (Challenger 605: 12 seats; Falcon 6X: 16 seats).
- The Falcon 6X is the newer design (introduced 2023 versus 2006 for the Challenger 605), a gap of 17 years that usually shows up in avionics, cabin systems and fuel burn.
- The Falcon 6X is the larger aircraft by maximum takeoff weight (72,000 lbs versus 48,300 lbs), which typically buys more cabin and payload at the cost of higher trip economics.
Which mission suits which aircraft
Both aircraft are built for long-haul and transatlantic missions, so outright range rarely separates them — the call leans on cabin (the Falcon 6X seats more), trip economics and what is actually available on the market. Match the airframe to how you fly most weeks, not to the headline range figure.
Which should you choose?
On published specifications the Falcon 6X leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The Challenger 605 can still be the smarter buy on acquisition cost, operating economics, runway performance, or current availability — the factors that rarely show up in a spec sheet. Our acquisition advisory team can model both against your actual mission profile before you commit.
