Airbus Helicopters H225 vs Bell 525 Relentless vs Leonardo Aw189 vs Piaggio Avanti Evo

The Airbus H225, Bell 525 Relentless, and Leonardo AW189 are all large, twin‑engine helicopters aimed at offshore transport and utility missions, while the Piaggio Avanti EVO is a twin‑turboprop fixed‑wing business aircraft optimized for fast point‑to‑point travel. By category, the H225 is the heaviest and most “super‑medium/heavy” oriented, the Bell 525 and AW189 sit in the modern super‑medium class, and the Avanti EVO is a pressurized executive aircraft rather than a rotorcraft. In range, the Avanti EVO typically offers the longest practical point‑to‑point capability (roughly 1,400–1,800 nm depending on payload and reserves). Among the helicopters, the H225 and AW189 are commonly configured for offshore legs on the order of a few hundred nautical miles, with the H225 generally strongest for longer offshore profiles; the Bell 525 is designed to be competitive in similar super‑medium missions with comparable medium‑to‑long helicopter range. For passenger capacity, the H225 usually carries the most in typical offshore layouts (often around 16–19), the AW189 and Bell 525 are broadly similar in the mid‑teens depending on configuration, and the Avanti EVO is typically arranged for about 6–9 passengers in executive seating.
