Dassault Falcon 6X vs Bombardier Challenger 650
The Matchup
The Falcon 6X is Dassault's newest large-cabin jet — cutting-edge fly-by-wire with the widest cabin in its class. The Challenger 650 is one of the most proven platforms in aviation — over 1,100 built across the Challenger 600 series. This comparison pits brand-new technology against battle-tested reliability. If you're deciding between the latest and the proven, here's how they stack up.
Head to Head
| Dassault Falcon 6X | Spec | Bombardier Challenger 650 |
|---|---|---|
| 5,500 NM at Mach 0.85★ | Range | 4,000 NM at Mach 0.80 |
1,500 NM more range. This is a major advantage — the 6X covers transatlantic routes, Dubai to East Asia, and other intercontinental city pairs that the Challenger 650 simply can't reach nonstop. | ||
| Mach 0.90★ | Max Speed | Mach 0.85 |
Significantly faster cruise capability. On a 3,000 NM sector, the 6X arrives 20–30 minutes earlier. | ||
| 8 ft 6 in★ | Cabin Width | 7 ft 11 in |
Seven inches wider — and the 6X's 8'6" matches the G650ER for the widest cabin in business aviation. This is a flagship-level cross-section in a sub-$60M aircraft. | ||
| 40 ft 4 in★ | Cabin Length | 28 ft 5 in |
Nearly 12 feet longer. The 6X's three-zone cabin dwarfs the Challenger's two zones. For groups of 8+ passengers, the difference is dramatic. | ||
| 6 ft 6 in★ | Cabin Height | 6 ft 1 in |
Five inches taller — the tallest cabin height in the large-cabin segment. Full stand-up headroom for virtually any passenger. | ||
| 12–16★ | Passengers | 10–12 |
| 51,000 ft★ | Ceiling | 41,000 ft |
10,000 feet higher. The 6X cruises above weather and traffic; the Challenger's 41,000 ft ceiling means more turbulence encounters and air traffic interactions. | ||
| 5,480 ft | Takeoff Distance | ★4,910 ft |
The Challenger needs less runway to get airborne — 570 feet less. A practical advantage at shorter airports. | ||
| 2,260 ft★ | Landing Distance | 2,440 ft |
The Falcon's fly-by-wire precision delivers 180 feet shorter landing. Dassault's fighter-jet heritage shows up here. | ||
| 2× Pratt & Whitney Canada PW812D (13,000 lbs each)★ | Engines | 2× GE CF34-3B (9,220 lbs each) |
The PW812D is a new-generation engine. The CF34 is one of the most reliable engines ever built. The Falcon has more thrust for its missions; the Challenger has decades of proven reliability. | ||
| $44.11M–$59.4M Vref (July 2026) | 2026 Acquisition Market Reference | $18.995M asking — 2016 SN 6084 |

Falcon 6X
Wider, longer, taller, higher ceiling. The 6X's cabin is a generation ahead of the Challenger 650 in every dimension. If passenger comfort is your top priority, the 6X is transformative.
Challenger 650
Deep fleet, strong brand recognition, bulletproof reliability, lower operating costs. The Challenger 650 is one of the most popular charter types globally.
Falcon 6X
Full fly-by-wire, FalconEye combined vision system, 51,000 ft ceiling, and a brand-new airframe. The 6X is the most technologically advanced aircraft in this comparison by a wide margin.
The Final Take
If you can afford the Falcon 6X and your missions require its range, speed, and cabin capabilities, it's the better aircraft in almost every measurable way. The fly-by-wire precision, the 51,000 ft ceiling, and the G650-matching cabin width set it apart from the Challenger. Buy the Falcon 6X if you need intercontinental range and premium cabin comfort. Buy the Challenger 650 if you value proven reliability, operating economics, and the best pre-owned value in large-cabin aviation.
