Airbus Helicopters H215 vs Bell 525 Relentless vs Airbus Helicopters H155

The Airbus H215 and Bell 525 Relentless sit in the super‑medium class, while the Airbus H155 is a lighter medium twin. In typical roles, the H215 is optimized for utility and offshore lift with a larger cabin and higher useful load, commonly carrying around 19 passengers in high‑density layouts, whereas the Bell 525 is positioned as a modern, long‑range super‑medium with a premium cabin and usually accommodates fewer passengers than an H215 in practice, often around the mid‑teens depending on configuration. The H155 is aimed more at corporate/VIP and EMS missions, with a smaller cabin and typically seats about 12–13 passengers in transport layouts. On range, the Bell 525 is generally marketed as the longest‑legged of the three, suitable for extended offshore sectors. The H215’s range is strong for its category but is typically less than the 525 when both are configured for maximum endurance. The H155 generally offers the shortest range of the trio, though it remains capable for regional passenger and medical missions where speed, comfort, and operating efficiency matter more than maximum payload.
