Bell 525 Relentless vs Embraer Legacy 650 E vs Gulfstream G700 vs Sikorsky S 92

The Bell 525 Relentless is a super‑medium helicopter aimed at offshore and corporate shuttle missions. Compared with the jets, its range is far shorter—roughly in the high hundreds of nautical miles—and it typically carries around a dozen-plus passengers in high‑density layouts (fewer in VIP), trading speed and endurance for vertical lift and point‑to‑point access. The Sikorsky S‑92 is a larger, heavy helicopter optimized for offshore transport and SAR; it generally carries more people than the 525 in transport configurations (often around 19) with a similar “under ~1,000 nm” class range depending on fit and reserves. The Embraer Legacy 650E is a long‑range large‑cabin business jet, commonly configured for about 13–14 passengers, with intercontinental capability around the 3,900 nm class. The Gulfstream G700 is an ultra‑long‑range flagship jet with a much larger cabin and typical seating in the mid‑teens to high‑teens (up to around 19), and a range around 7,500 nm, enabling true global city‑pairs and substantially higher cruise speed than the Legacy 650E and either helicopter.
