Airbus Helicopters H225 vs Bell 525 Relentless vs Dassault Falcon 8x vs Robinson R66

The Airbus H225 and Bell 525 Relentless are large, twin‑engine helicopters aimed at offshore, search-and-rescue, and VIP transport. In category, both sit well above light utility helicopters, with the H225 generally positioned as a proven heavy/“super-medium” workhorse, while the 525 is a newer “super-medium” design emphasizing modern avionics and speed. Their range is broadly comparable for long helicopter missions, commonly in the several-hundred–nautical‑mile class, and both typically carry around a dozen to roughly twenty passengers depending on layout and mission equipment. The Dassault Falcon 8X is a long‑range business jet in a different class entirely: it offers intercontinental range measured in thousands of nautical miles and a typical executive capacity of about 12–16 passengers (with higher maximums in dense layouts), delivering far greater speed and range than any helicopter here. The Robinson R66 is a light, single‑engine helicopter focused on cost-effective utility and short-to-medium trips. It has much shorter range than the H225 or 525 and a much smaller cabin, typically seating a pilot plus four passengers.
