Bell 525 Relentless vs Dassault Falcon 8x vs Gulfstream G700 vs Piper M600 Sls

The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter aimed at offshore, SAR, and VIP missions rather than long-haul business travel. Its range is roughly 500–600 nautical miles, and typical passenger capacity is around 12–16 depending on cabin layout. The Dassault Falcon 8X is an ultra‑long‑range trijet business jet with a range around 6,450 nautical miles and usually carries 12–16 passengers in executive configurations. The Gulfstream G700 is a large-cabin, ultra‑long‑range business jet with a range about 7,500 nautical miles and typically accommodates 12–19 passengers, emphasizing maximum cabin volume and nonstop intercontinental legs. The Piper M600 SLS is a single‑engine turboprop designed for owner‑pilots and short-to-mid regional travel; its range is about 1,400 nautical miles and seating is generally up to 5–6 occupants. Overall, the G700 leads on range and cabin size, the 8X offers long range with trijet efficiency and flexibility, the M600 SLS prioritizes simplicity and cost for smaller groups, and the Bell 525 serves missions where vertical lift matters more than distance.
