Airbus Helicopters H160 vs Airbus Helicopters H175 vs Bell 525 Relentless vs Leonardo Aw139 vs Sikorsky S 76d

By category, the Airbus H160 and Sikorsky S‑76D sit in the medium twin class aimed at corporate, EMS and offshore roles, while the Leonardo AW139 is a larger “super‑medium” workhorse, and the Airbus H175 and Bell 525 Relentless compete in the upper‑medium/super‑medium offshore and utility segment with higher payload and cabin volume emphasis. In range, the H160 and S‑76D are typically optimized for short‑to‑mid missions, commonly in the roughly 450–520 nm class depending on fuel and reserves, whereas the AW139 usually lands in a similar band, often around 500–570 nm. The H175 generally stretches farther into the mid‑to‑upper 500 nm range, and the Bell 525 is designed for longer legs, frequently quoted around the 600–700+ nm class in typical configurations. For passenger capacity, H160 and S‑76D commonly seat about 10–12 passengers, the AW139 about 12–15, and both H175 and Bell 525 typically around 16–19 in high‑density offshore layouts, with VIP fits trading seats for space.
