Bell 525 Relentless vs Gulfstream G700 vs Leonardo Aw189 vs Piaggio Avanti Evo

The Bell 525 Relentless and Leonardo AW189 are super‑medium helicopters, suited to point‑to‑point missions where vertical lift matters more than speed. The 525 typically carries around 16–20 passengers in high‑density layouts (fewer in VIP), with practical range on the order of roughly 500–600 nautical miles depending on load and reserves. The AW189 is in a similar category, commonly configured for about 16–18 passengers, with a broadly comparable practical range often around 450–550 nautical miles. The Gulfstream G700 is an ultra‑long‑range large‑cabin business jet, optimized for intercontinental travel. It carries up to about 19 passengers in a high‑density configuration (often fewer for executive layouts) and offers roughly 7,500+ nautical miles of range, far exceeding the helicopters and enabling nonstop long‑haul missions. The Piaggio Avanti EVO is a pressurized twin‑turboprop business aircraft, bridging utility and executive travel. It typically seats about 7–9 passengers and offers medium range, roughly around 1,000–1,500 nautical miles depending on configuration, with cruise speeds closer to light jets than most turboprops.
