Bell 525 Relentless vs Embraer Legacy 650 E vs Piaggio Avanti Evo vs Robinson R66

The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter in the “super‑medium” rotorcraft category, aimed at offshore and executive missions. Its range is roughly in the 500–600 nautical mile class depending on reserves and payload, and it typically carries around 12–16 passengers in high-density layouts (fewer in VIP configurations). The Robinson R66 is a light, single‑engine helicopter with much shorter legs, generally around 300 nautical miles, and a 5‑seat capacity including the pilot. The Embraer Legacy 650E is a long‑range large business jet, optimized for intercontinental-style business travel; it offers about 3,900 nautical miles of range and commonly seats 13 passengers (with higher-capacity seating possible depending on layout). The Piaggio Avanti EVO is a high-speed twin‑turboprop business aircraft, positioned between light/midsize jets and turboprops; it typically seats 7–9 passengers and has an approximate 1,500–1,800 nautical mile range. Overall, the Legacy 650E leads on range and cabin capacity among fixed-wing options, the Avanti EVO trades some range for turboprop efficiency and speed, and the Bell 525 and R66 prioritize vertical lift with shorter point-to-point range.
