Specifications That Improved Efficiency
• Range: 4,455 km (2,405 nm) — slightly less than 800XP due to weight, but more efficient
• Speed: 745 km/h (402 knots) — same as 800XP
• Capacity: 8 – 9 passengers in the familiar cabin
• Winglets: Reduced fuel burn by 3 – 5% — small gain, but meaningful over time
• Production: Limited run between 2006 and 2009
The 850XP was a transitional model — better than the 800XP, but quickly overshadowed by the 900XP's engine upgrade.
