Bell 525 Relentless vs Robinson R66 vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are both in the medium, twin‑engine offshore/utility helicopter class, while the Robinson R66 is a light, single‑engine turbine helicopter aimed more at private, training, and light commercial missions. In range, the R66 is generally suitable for shorter point‑to‑point trips and local operations, whereas the Bell 525 is designed for longer overwater legs and higher-speed regional missions; the S-92 also targets extended offshore routes and typically supports long-range operations with robust payload and systems, often optimized for oil-and-gas transport. Passenger capacity follows the same pattern: the R66 commonly carries about four passengers plus a pilot (configuration dependent), the Bell 525 is typically configured in the mid‑teens for passengers for corporate or offshore transport, and the S-92 is usually configured for larger groups, commonly around 19 passengers in offshore seating, with variants and layouts influencing the exact numbers. Overall, the R66 prioritizes simplicity and lower operating scale, the 525 emphasizes modern avionics and efficient medium-lift capability, and the S-92 focuses on higher-capacity, heavy-duty transport.
