Piper M500 vs Piper M600 Sls

The Piper M500 and Piper M600 SLS are both single‑engine turboprop aircraft in Piper’s Meridian/M‑Class family, aimed at owner‑operators and small business travel, but they sit in different performance tiers. The M500 is the earlier, slightly lighter and lower‑power model, typically positioned as the more cost‑conscious entry point into pressurized turboprops, with solid cross‑country capability for regional and medium‑range trips. The M600 SLS is the newer, more powerful step‑up variant, designed to cruise faster and generally go farther, making it better suited to longer nonstop missions and higher‑utilization travel. In range, the M600 SLS generally offers a modest advantage over the M500 under comparable conditions, although real‑world range for either depends heavily on payload, winds, altitude, and reserve requirements. In passenger capacity, both aircraft are commonly configured for one pilot plus up to five passengers (six seats total), with similar cabin class and mission profile, but the M600 SLS more consistently delivers that capability with stronger performance margins.
