The Piper Matrix, in contrast to the Piper Mirage, does not feature a pressurization mechanism, as does the Piper Mirage. While this is the most significant difference, early Matrix aircrafts also featured inferior avionics, such as the S-Tec 55X; however, this was eventually corrected when Piper supplied the same Garmin G1000 to Matrix as well as other aircraft. Aside from that, they are very identical, except for the Matrix having some more usable load capacity due to the elimination of some sections of the pressure system.
