Bell 525 Relentless vs Boeing Bbj Max 9 vs Dassault Falcon 8x vs Piaggio Avanti Evo

The Bell 525 Relentless is a fly-by-wire super‑medium helicopter aimed at point‑to‑point access and vertical operations; it typically carries about 16–19 passengers in high‑density layouts (fewer in executive fit) and has roughly a 500–600 nautical mile class range depending on reserves and payload. The Boeing BBJ MAX 9 is a large, long-range VIP airliner category aircraft; it offers by far the greatest cabin volume, commonly configured for roughly 25–50 passengers in corporate layouts, and can fly about 6,000–6,600 nautical miles. The Dassault Falcon 8X is an ultra‑long‑range business jet; it usually seats about 8–16 passengers and is known for intercontinental capability around 6,450 nautical miles. The Piaggio Avanti EVO is a twin‑turboprop business aircraft optimized for speed and efficiency on regional missions; it generally seats 6–9 passengers and has about a 1,400–1,800 nautical mile range. Overall, the BBJ MAX 9 leads in capacity, the Falcon 8X leads in long-range business-jet flexibility, the Avanti EVO is the efficient regional option, and the Bell 525 is unique for VTOL access rather than runway range.
