Airbus Helicopters H175 vs Airbus Helicopters H225 vs Bell 525 Relentless vs Leonardo Aw109 Grand New vs Leonardo Aw139 vs Sikorsky S 76d vs Sikorsky S 92

The Airbus H175 and H225 and the Sikorsky S-92 sit in the medium-to-heavy offshore/utility class. They typically offer the longest legs and the highest cabin loads in this group: the H225 and S-92 generally carry about 16–19 passengers (depending on layout) and are commonly used on longer offshore sectors, while the H175 is usually positioned slightly below them at roughly 16 passengers with long-range capability but not quite the same payload/cabin volume as the heavy twins. The Bell 525 Relentless and Leonardo AW139 are in the upper-medium “super-medium” category, aimed at fast, long-range offshore and corporate missions. They commonly seat around 12–16 passengers, with ranges broadly comparable to or slightly below the heavy twins depending on configuration, while offering strong cruise speed and modern avionics. The Sikorsky S-76D and Leonardo AW109 Grand New are lighter twins optimized for corporate, EMS, and short-to-mid-range utility. They typically carry about 6–8 passengers, with shorter range than the super-medium and heavy types, trading cabin volume for efficiency, agility, and lower operating footprint.
