Airbus Helicopters H175 vs Bell 525 Relentless vs Bombardier Global 8000 vs Gulfstream G700 vs Leonardo Aw139 vs Leonardo Aw189 vs Sikorsky S 76d

The Airbus Helicopters H175 and Leonardo AW189 sit in the super-medium class, offering similar long-range offshore capability at roughly 500–600 nm and typically carrying about 16–19 passengers in high-density seating (often fewer in VIP layouts). The Bell 525 Relentless is a newer super-medium with comparable mission intent, generally in the same ~500+ nm range class and usually configured around 16 passengers. The Leonardo AW139 and Sikorsky S‑76D are medium twins; the AW139 is commonly set up for about 12–15 passengers with range roughly in the 500 nm class depending on tanks and reserves, while the S‑76D is typically 8–12 passengers with a shorter range around ~400 nm. In contrast, the Bombardier Global 8000 and Gulfstream G700 are ultra-long-range business jets: the Global 8000 targets about 8,000 nm range with typical cabins seating roughly 8–19, while the G700 is around 7,500 nm with a similar typical capacity (often 10–19). Overall, the jets dominate intercontinental range and cabin volume, while the helicopters prioritize vertical access and offshore/regional reach.
