Bell 525 Relentless vs Dassault Falcon 8x vs Gulfstream G700 vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are helicopters, while the Dassault Falcon 8X and Gulfstream G700 are long-range business jets, so their strengths differ fundamentally. The Bell 525 is positioned as a modern super-medium helicopter for regional missions, typically carrying about 12–16 passengers depending on configuration, with a practical range around 500–600 nautical miles. The Sikorsky S-92 is a larger, heavy helicopter commonly used for offshore and utility/VIP roles, often seating about 18–19 passengers, with typical range roughly 500–600 nautical miles. By contrast, the Falcon 8X is an ultra-long-range trijet business jet optimized for efficiency and access to shorter runways, typically seating about 12–16 passengers, with range around 6,450 nautical miles. The Gulfstream G700 is a flagship large-cabin, ultra-long-range jet focused on maximum cabin space and speed, typically accommodating about 13–19 passengers, with range around 7,500 nautical miles. Overall, the helicopters trade intercity range for vertical-lift access, while the jets dominate nonstop intercontinental travel.
