The O 321 was the world's first bus with unitary body construction and the second bus with a rear engine (the first was the Mercedes O 6600 H of 1951). This design provided good handling and braking. The O 321 was also relatively light for a midsize bus. Research and initial designs began in the early 1950s but it wasn't until 1954 that the O 321 was ready. The cockpit was designed with ergonomics and simplicity in mind.
Throughout much of its production span in Mannheim, it was powered by a 5.1-litre 6-cylinder inline diesel engine with antechamber design and 110 hp. Later, a 5.7-litre 6-cylinder diesel with 127-hp was offered. The O 321 was a sales success; by 1964 over 30,000 had been sold, a third of them overseas with the bus being popular in the Middle East, Africa and South America.
