Piper changed gears five years after the introduction of the Malibu when it came out with an updated version, the Mirage. The most noteworthy change was to the 350 hp Lycoming TIO-540, the engine that it still uses today. It is more powerful and delivers slightly faster airspeeds, but it also burns more fuel, so the range, while good, isn't what it used to be. The Mirage also got a new, much nicer interior, better radar, heated windshield (to replace the hot plate on the Malibu) and a 200-pound weight increase to help offset the additional weight of the new systems, especially the heavier engine. It was a more substantial-feeling airplane with a nicer interior and better features and systems all around, though even with the gross weight increase, it still lost a little useful load in the upgrade.
