Bell 412epi vs Bell 525 Relentless vs Sikorsky S 76d

The Bell 412EPi is a medium, twin‑engine utility helicopter optimized for rugged, multi‑role missions rather than maximum speed or cabin luxury. It typically carries about 10–13 passengers depending on interior configuration, and offers moderate range suited to regional transport and public‑service work. The Bell 525 Relentless is a larger, next‑generation “super‑medium” twin designed for higher cruise speeds, modern avionics, and offshore/business transport efficiency. It generally seats around 16 passengers in a high‑density layout (fewer in executive interiors) and is aimed at longer legs than the 412, giving it a clear advantage for extended overwater or point‑to‑point missions. The Sikorsky S‑76D is a light‑to‑medium twin with a strong reputation in executive and offshore roles. It commonly carries about 12 passengers (or fewer in VIP fit) and provides solid range that often exceeds utility‑focused mediums like the 412, though it is typically positioned below super‑medium aircraft such as the 525 for payload‑range capability.
