Demanding specifications for the standard inter-urban service bus

Whereas the O 302 had been designed to cater for both city and inter-urban operations, there was to be a major difference between the standard inter-urban bus and the city bus, for in 1967 the VÖV had specified a low floor height for city buses to make it as easy as possible for passengers to enter and leave the vehicle. The inter-urban bus, however, was to have a luggage compartment with a capacity of at least 2.5 cubic meters which could only be accommodated beneath the floor, between the axles.

Moreover, with a length of 11.7 meters the inter-urban bus was to be slightly longer than the 11-meter VÖV city bus. Comfortable seat rows were to be provided for roughly half of the 102 passengers. Where the cockpit was concerned the working group followed the lead of the city bus. The engine output was to be in the region of 200 hp.

Daimler-Benz responds with the O 307

It was therefore clear that city and inter-urban operations could not be combined in a single model series. Nonetheless Daimler-Benz did not miss the opportunity to include its own rationalization efforts in the design concept for the inter-urban bus, and made sure that the greatest possible number of O 305 city bus components were adopted in the O 307, which was presented in 1973. These included not only frame and body components, but also the highly praised, practical and clearly arranged cockpit.

Conversely the city bus adopted the 210 hp six-cylinder OM 407h engine from the O 307 in 1973, replacing the original OM 360h which had an output of only 192 hp. This eleven-liter engine was installed horizontally at the rear, with a 180 hp low-emission variant also available on request. In 1973 Daimler-Benz also introduced a sound-insulated version, the "whispering bus". To quote a press release: "The engine encapsulation system reduces engine noise to such an extent that the engine of a passing bus can scarcely be heard."
