320 kt cruise, fastest turboprop in production of its era
With the Garrett TPE331-10 (776 SHP) on the Marquise variant (B-60), the MU-2 reaches 320 kt in high cruise, jet-like performance that places the MU-2 among the fastest executive turboprops ever produced, comparable to early Citation jets. The speed comes from the aerodynamically optimized fuselage, short-span wing and reduced drag from the absence of ailerons (replaced by spoilers).
