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

Airbus Helicopters’ H160 sits in the medium class, optimized for efficiency and lower noise, with a typical range around 450–480 nm and usually configured for about 10–12 passengers. The Airbus H175 is a heavier super‑medium, aimed at offshore and SAR, offering roughly 600+ nm range with auxiliary fuel and commonly carrying about 16–18 passengers in transport layouts. Bell’s 525 Relentless is also super‑medium, designed for long offshore sectors; range is typically in the 560–650 nm class depending on fuel fit, with passenger seating commonly around 16–18. Leonardo’s AW139 is a medium twin widely used for EMS, corporate and offshore; it generally offers about 550–650 nm range and typically seats around 12–15 passengers. The larger AW189 is super‑medium, prioritizing payload and offshore endurance, with roughly 500–650 nm range depending on tanks and usually about 16–19 passengers. Sikorsky’s S‑76D is a lighter medium twin focused on corporate/EMS speed and efficiency, generally around 400–450 nm range and typically configured for about 8–12 passengers. Actual figures vary with interiors, reserves, and optional tanks.
