Airbus Helicopters H225 vs Bell 525 Relentless vs Piaggio Avanti Evo vs Sikorsky S 92

The Airbus H225 and Sikorsky S-92 are heavy, twin‑engine helicopters optimized for offshore transport, search and rescue, and utility work; both typically carry around 16–19 passengers in offshore-style seating, with operational range commonly in the roughly 450–550 nautical mile class depending on configuration and reserves. The Bell 525 Relentless is a modern “super‑medium” twin helicopter, generally a step below H225/S‑92 in lift category, aimed at offshore and corporate missions; it typically seats about 16 passengers and is marketed with range in a similar mid‑500 nautical mile bracket, again highly dependent on payload and mission rules. The Piaggio Avanti EVO is a pressurized twin‑turboprop fixed‑wing aircraft rather than a helicopter; it is usually configured for about 6–8 passengers, cruises much faster than the rotorcraft, and typically offers longer point‑to‑point range (often around 1,000–1,500 nautical miles) but lacks vertical lift and hover capability. Overall, H225/S‑92 emphasize heavy-lift offshore capacity, Bell 525 balances speed and modern avionics in the super‑medium class, and Avanti EVO prioritizes fast regional transport with fewer passengers.
