Bell 525 Relentless vs Piaggio Avanti Evo vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are both twin‑engine helicopters, while the Piaggio Avanti EVO is a twin‑turboprop fixed‑wing business aircraft. In category terms, the 525 is a super‑medium helicopter aimed at offshore, corporate, and utility missions; the S‑92 is a larger heavy helicopter commonly used for offshore transport, search and rescue, and high‑capacity utility roles; the Avanti EVO is a pressurized business aircraft optimized for fast point‑to‑point travel between airports. For range, the Avanti EVO generally offers the longest legs because it is a fixed‑wing airplane, typically around 1,700–1,800 nautical miles depending on configuration. The Bell 525 is designed for long offshore-style helicopter missions, roughly on the order of 500–600 nautical miles. The S‑92’s range is broadly similar but often a bit lower in typical passenger configurations, roughly in the 450–550 nautical mile class. For passenger capacity, the Avanti EVO is usually configured for about 7–9 passengers, the Bell 525 commonly around 12–16, and the S‑92 typically around 18–19 (and can be configured higher in utility layouts).
