Bell 525 Relentless vs Gulfstream G700 vs Robinson R66 vs Sikorsky S 92
The Bell 525 Relentless and Sikorsky S-92 are large, twin‑engine helicopters, while the Gulfstream G700 is an ultra‑long‑range business jet and the Robinson R66 is a light, single‑engine helicopter. In range, the G700 is in a different class, capable of roughly 7,000+ nautical miles, suitable for intercontinental nonstop missions. The Bell 525 is a medium helicopter with a typical range on the order of 500–600 nautical miles, aimed at offshore and corporate shuttle roles. The Sikorsky S-92, a heavier transport helicopter, is broadly comparable in mission type, generally around 500 nautical miles depending on configuration, and optimized for offshore, SAR, and utility transport. The Robinson R66 has the shortest reach, roughly 300+ nautical miles, and is commonly used for private, training, and light commercial work. For passenger capacity, the G700 typically carries about 10–19 passengers in executive layouts. The S-92 can carry about 19 passengers in high‑density seating, while the Bell 525 is typically around the mid‑teens. The R66 usually seats about 4 passengers plus a pilot.
