Airbus Helicopters H160 vs Airbus Helicopters H175 vs Bell 525 Relentless vs Leonardo Aw169 vs Leonardo Aw189 vs Sikorsky S 76d

All six are modern twin‑engine civil helicopters, but they split into light‑intermediate and super‑medium roles. The Airbus H160 and Leonardo AW169 sit in the lighter/medium segment, typically carrying about 6–10 passengers in offshore or corporate layouts, with ranges commonly in the roughly 450–500+ nautical mile class depending on tanks and payload. The Sikorsky S‑76D is also in this general light‑intermediate bracket, usually configured around 6–8 passengers, with a broadly similar medium range profile. Stepping up, the Airbus H175 and Leonardo AW189 are super‑mediums aimed at offshore and SAR missions, commonly arranged for about 12–16 passengers and offering longer practical ranges, often around the 500–600+ nautical mile class with appropriate fuel options. The Bell 525 Relentless competes in the same super‑medium space, typically seating roughly 12–16 passengers and targeting comparable medium‑to‑long ranges, often cited around the 500+ nautical mile class. In short, H160/AW169/S‑76D emphasize smaller cabins and flexibility, while H175/AW189/525 emphasize higher passenger capacity and offshore‑style range.
