Bell 525 Relentless vs Piaggio Avanti Evo vs Piper M600 Sls vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are helicopters, while the Piaggio Avanti EVO and Piper M600 SLS are fixed‑wing turboprops; that category split largely drives their differences. For range, the fixed‑wing aircraft generally lead: the Piper M600 SLS is oriented toward long, efficient owner-flown trips, while the Piaggio Avanti EVO typically offers similarly strong or greater point‑to‑point range with higher cruise efficiency and speed in the turboprop class. The Bell 525 targets medium-to-long helicopter missions, commonly offering longer legs than many medium twins but usually less point‑to‑point range than comparable fixed‑wing turboprops. The Sikorsky S-92 is a larger, heavy helicopter optimized for offshore and utility work, with solid range but again generally constrained versus fixed‑wing aircraft on pure distance. Passenger capacity separates them most: the Piper M600 SLS is a single‑pilot capable aircraft typically seating around six, the Avanti EVO usually carries more (often seven to nine). The Bell 525 commonly accommodates a larger cabin load (often up to the low teens depending on layout), while the S-92 is the clear high-capacity option, frequently configured for roughly 19 passengers.
