Bell 525 Relentless vs Enstrom 480b vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 sit in larger, medium-class twin‑engine categories aimed at offshore and corporate transport, while the MD Helicopters 902 Explorer and Enstrom 480B are lighter platforms typically used for utility, patrol/training, and short‑to‑medium missions. In passenger capacity, the S‑92 generally leads among these four, commonly configured to carry more passengers in transport roles; the Bell 525 is close behind with a high-capacity cabin for its class. The MD 902 typically carries fewer passengers than the 525 and S‑92 but more than many light singles, making it a mid‑light option. The Enstrom 480B is a light single‑engine helicopter and usually has the smallest passenger capacity of the group. For range, the S‑92 and Bell 525 tend to offer the longest practical ranges thanks to twin‑engine, transport-oriented designs and larger fuel fractions, with the 525 often positioned as a long-range modern alternative in its segment. The MD 902’s range is generally moderate, and the Enstrom 480B’s range is typically the shortest, reflecting its lighter, single‑engine role.
