Airbus Helicopters H160 vs Airbus Helicopters H175 vs Airbus Helicopters H225 vs Bell 525 Relentless vs Leonardo Aw139 vs Leonardo Aw189 vs Sikorsky S 76d vs Sikorsky S 92

Airbus H160 and Sikorsky S-76D sit in the medium twin class: they typically carry about 12 passengers (depending on layout) and offer medium-range capability suited to regional offshore, EMS, and corporate missions. The Leonardo AW139 and Airbus H175 are “super-medium” twins, generally configured around 12–16 passengers with longer legs than H160/S-76D, making them common for offshore transport and SAR where speed and cabin volume matter. Bell 525 Relentless also targets the super-medium segment, with a similar 12–16 passenger class cabin and competitive range intended for longer offshore sectors. Moving up, the Leonardo AW189 bridges super-medium to heavy, often arranged around 16–19 passengers with extended range options optimized for offshore lift. The heavy twins Airbus H225 and Sikorsky S-92 are the largest in this group, commonly carrying roughly 19 passengers in offshore layouts and providing the longest practical range and payload margins for demanding offshore, SAR, and utility missions. Overall, capacity and range generally step up from H160/S-76D, to AW139/H175/525, to AW189, and peak with H225/S-92.
