Bell 525 Relentless vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Robinson R66 vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S‑92 sit in the large, twin‑engine, IFR-certified helicopter class aimed at offshore transport, corporate shuttle, and high-utilization missions. Both typically offer the longest usable range in this group and the highest passenger capacity; the S‑92 is commonly configured for roughly 19 passengers, while the 525 is often arranged in the mid‑ to high‑teens depending on interior and mission equipment. The MD Helicopters (McDonnell Douglas) 902 Explorer is a smaller, light twin designed for utility, law enforcement, and corporate roles, with a more modest range and generally single‑digit seating—often around 7–8 passengers depending on layout. The Robinson R66 is a light, single‑engine turbine helicopter focused on cost-effective private, training, and light utility use. It has the shortest range and the smallest cabin here, typically carrying about 4 passengers plus the pilot (five seats total). Overall, capability and capacity scale upward from the R66 to the 902, then to the 525 and S‑92 at the top end.
