Bell 525 Relentless vs Bombardier Global 7500 vs Gulfstream G700 vs Piaggio Avanti Evo

The Bell 525 Relentless is a fly-by-wire super‑medium helicopter, optimized for vertical access rather than long-haul cruise. Its typical range is roughly 500–700 nautical miles depending on load, and it generally seats about 16–20 passengers in a high-density configuration (often fewer in executive layouts). The Piaggio Avanti EVO is a twin‑turboprop business aircraft aimed at efficient regional flying. It typically offers about 1,400–1,800 nautical miles of range and usually carries 6–9 passengers in executive seating. The Bombardier Global 7500 and Gulfstream G700 are ultra‑long‑range business jets designed for intercontinental missions. The Global 7500 is commonly cited around 7,700 nautical miles with a typical executive load of about 8–19 passengers. The Gulfstream G700 is in the same class at roughly 7,500 nautical miles and typically seats about 10–19 passengers. Overall, the helicopter wins on access and point-to-point flexibility, the Avanti EVO targets efficient mid-range trips, and the Global 7500/G700 dominate for range, speed, and long-cabin comfort.
