Bell 525 Relentless vs Embraer Legacy 650 E vs Robinson R66 vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are medium, twin‑engine helicopters aimed at offshore, corporate, and mission roles. The S-92 is the heavier, higher-capacity transport, typically configured for roughly 19 passengers, while the Bell 525 is generally configured for fewer, often around 12–16 depending on layout. Their practical ranges vary by configuration and reserves, but both commonly fall in the several-hundred–nautical-mile class, with the 525 often cited around the high‑400s to ~500 nm and the S‑92 often around the ~500–600 nm neighborhood. The Robinson R66 is a light, single‑engine helicopter designed for private and utility use; it carries about 4 passengers plus a pilot and has a shorter range, roughly in the ~300–350 nm class. The Embraer Legacy 650E is a large‑cabin business jet rather than a helicopter; it typically seats about 13 passengers (with higher-density layouts possible) and has a far longer range, roughly ~3,900 nm, making it suited to intercontinental city pairs that are well beyond rotorcraft reach.
