Introduced for the model year 1969, the larger, Baron 58 was developed from the Baron 55, introducing club seating, double aft baggage doors, and new gross weight of 5,400 lbs. Depending on the variant, the Baron 58 is fitted with either the Continental IO-520 or IO-550 300-hp engine. The Baron 58 can cruise at 200 knots (370 km/h) at 7000 ft (2100 m). The lengthening of the fuselage increased rear baggage space, as well as providing more comfortable six-place seating over the Baron 55 and 56TC.
