Bell 525 Relentless vs Leonardo Aw189 vs Md Helicopters (mcdonnell Douglas) 902 Explorer

The Bell 525 Relentless and Leonardo AW189 are both modern, medium-category twin‑engine helicopters aimed at offshore, corporate, and high-utility missions, while the MD Helicopters 902 Explorer is a lighter twin designed more for EMS, law enforcement, and general utility. In category terms, the 525 and AW189 sit in the medium class with higher takeoff weights and more space; the 902 is typically considered a light twin. For range, the Bell 525 and AW189 generally offer substantially longer legs than the MD 902, reflecting larger fuel capacity and more efficient cruise in the medium class. Between the two medium helicopters, published range varies by configuration, but both are commonly suited to longer offshore sectors, with the 525 often positioned as a long-range performer in its class. Passenger capacity follows the same pattern. The AW189 and Bell 525 are typically configured around 16–19 passengers in high-density layouts (with fewer in VIP or missionized interiors), whereas the MD 902 commonly seats about 7–10 including crew depending on cabin fit and mission equipment.
