Bell 525 Relentless vs Enstrom 480b vs Gulfstream G700 vs Piaggio Avanti Evo

The Bell 525 Relentless and Enstrom 480B are helicopters, while the Gulfstream G700 and Piaggio Avanti EVO are fixed‑wing business aircraft, so their range and cabin expectations differ substantially. The Bell 525 is a modern super‑medium helicopter aimed at offshore and corporate missions, offering longer helicopter range and a roomier cabin than light piston/turbine singles, typically configured for around a dozen-plus occupants depending on layout. The Enstrom 480B is a smaller utility helicopter with much shorter range and a far lower passenger load, generally suited to a pilot plus a few passengers. Among the airplanes, the Gulfstream G700 is a long‑range, large‑cabin business jet designed for intercontinental missions, carrying a relatively high number of passengers in executive comfort and delivering the greatest range of the four by a wide margin. The Piaggio Avanti EVO is a high‑speed twin‑turboprop business aircraft, usually seating fewer than large jets but more than small helicopters, with medium range suited to regional to transcontinental legs depending on payload and reserves.
