Airbus Helicopters H225 vs Bell 525 Relentless vs Enstrom 480b vs Robinson R66

The Airbus H225 sits in the heavy, long-range offshore/utility category, offering the greatest reach and the highest passenger throughput of this group, typically carrying around 19 passengers (configuration dependent) and designed for demanding overwater and SAR missions. The Bell 525 Relentless is a large “super-medium” twin aimed at offshore transport with modern avionics; it generally provides long range competitive with offshore needs and usually accommodates roughly 16 passengers, balancing speed, payload, and cabin comfort below the H225’s heavy-lift class. The Enstrom 480B is a light single-engine turbine utility helicopter with a much shorter range than the offshore twins and a small cabin, typically seating 5, optimized for patrol, training, and general utility rather than high-capacity transport. The Robinson R66 is also a light single turbine, commonly configured for 5 seats, and is oriented toward private, training, and light utility roles; its typical range is modest, generally in the same broad “light helicopter” bracket as the 480B and well below the twin-engine offshore aircraft.
