Airbus Helicopters H225 vs Bell 525 Relentless vs Embraer Legacy 650 E vs Leonardo Aw189

The Airbus H225 and Leonardo AW189 are large, twin‑engine helicopters aimed at offshore transport and utility missions, while the Bell 525 Relentless is a newer super‑medium twin targeting similar offshore and corporate shuttle roles with modern avionics and fly‑by‑wire. The Embraer Legacy 650E is a long‑range business jet, so its category and performance sit apart from the helicopters, prioritizing fast intercity and intercontinental travel. On range, the Legacy 650E is in a different class, typically around 3,900 nautical miles, far exceeding any of the rotorcraft. Among the helicopters, the H225 generally offers the longest reach (commonly quoted around the mid‑400 nm class depending on fit), with the AW189 and Bell 525 typically in the roughly 400 nm neighborhood, again varying with payload, reserves, and mission equipment. For passenger capacity, the helicopters can be configured for higher seat counts in transport layouts: H225 often around 19 passengers, AW189 around 16–19, and Bell 525 commonly around 16–20 depending on configuration. The Legacy 650E typically carries about 13–14 passengers in executive seating.
