Airbus Helicopters H160 vs Beechcraft King Air 360 vs Bell 525 Relentless vs Leonardo Aw139 vs Piaggio Avanti Evo

The Airbus Helicopters H160 and Leonardo AW139 are medium twin helicopters optimized for vertical access; the H160 is typically configured for about 6–12 passengers with roughly 450–500 nm range, while the AW139 commonly carries about 8–15 passengers with around 550–600 nm range depending on fit and reserves. The Bell 525 Relentless is a larger, long-range super-medium helicopter, generally aimed at about 12–16 passengers with roughly 600–700+ nm range, emphasizing offshore-style legs and higher cruise speed for a rotorcraft. The Beechcraft King Air 360 and Piaggio Avanti EVO are pressurized fixed‑wing turboprops designed for runway-to-runway efficiency and longer legs than most helicopters. The King Air 360 typically seats about 6–9 passengers with about 1,500+ nm range, prioritizing short-field capability and utility. The Avanti EVO usually carries about 7–9 passengers with roughly 1,300–1,700 nm range and stands out for higher cruise speed and cabin comfort relative to many turboprops. Actual figures vary by payload, reserves, and interior.
