Airbus Helicopters H135 vs Bell 525 Relentless vs Leonardo Aw109 Grand New

The Airbus Helicopters H135 is a light, twin‑engine helicopter best suited to short to medium missions such as EMS, police, and utility work. Its typical passenger capacity is around five to six passengers plus one or two pilots (depending on interior and mission fit), and its practical range is generally in the few‑hundred‑nautical‑mile class, optimized more for flexibility and operating cost than long legs. The Leonardo AW109 GrandNew is also a light twin, but it is usually positioned as a faster, more premium light helicopter for corporate and VIP transport. It typically carries about six to seven passengers plus one or two pilots, with a range broadly comparable to the H135—again generally a few hundred nautical miles—though configured to emphasize speed and executive comfort. The Bell 525 Relentless is a larger “super‑medium” twin designed for longer‑range missions and higher payload, including offshore transport. It offers substantially greater passenger capacity, commonly up to about sixteen passengers in typical layouts, and a materially longer range, commonly on the order of several hundred nautical miles and often approaching or exceeding the ~500‑nautical‑mile class depending on configuration.
