Bell 525 Relentless vs Bombardier Global 7500 vs Piper M600 Sls vs Robinson R66

The Bell 525 Relentless and Robinson R66 are helicopters, while the Bombardier Global 7500 and Piper M600 SLS are fixed‑wing airplanes; they serve very different missions and budgets. In category and role, the Global 7500 is an ultra‑long‑range business jet optimized for intercontinental travel at high speed and altitude, whereas the Piper M600 SLS is a single‑engine turboprop aimed at owner‑pilots and regional point‑to‑point trips. The Bell 525 is a large, fly‑by‑wire super‑medium helicopter designed for offshore, corporate, and utility missions, while the R66 is a light turbine helicopter focused on short-range transport and training. In range, the Global 7500 is the clear outlier at roughly 7,700 nautical miles, enabling nonstop long-haul routes. The M600 SLS typically offers around 1,400 nautical miles. Helicopters generally have shorter legs: the Bell 525 is on the order of 500–600 nautical miles depending on configuration, and the R66 is typically around 300–350 nautical miles. In passenger capacity, the Global 7500 commonly carries about 8–19, the Bell 525 around 12–16, the M600 SLS up to 6, and the R66 seats 5 including the pilot.
