In 1970, the rear-engine OH 1313 and the front-engine OF 1313 bus chassis were unveiled. One year later, a new integral coach was unveiled – the O 362 – featuring a larger luggage compartment than its predecessor, the O 321. Yet another integral bus was presented by Mercedes-Benz do Brasil – the O 355 – in 1974. The OH 1517 rear-engine chassis was also presented that year. One year after the first three-axle bus was built in Brazil (based on the Mercedes-Benz LPO 1113 front-engine chassis) made its debut in 1977, the new O 364 integral bus was presented by Mercedes-Benz do Brasil in two versions – one with a 130-hp engine, and the other with a 170-hp engine. Also in 1978 the production of the O 362 was discontinued, after more than 35,100 units were produced in Brazil.
