A six cylinder in line diesel introduced by Leyland for trucks in 1946 but used in their buses from 1947 until 1972. It was used in double deck PD2, PD3, Lowlander and some early Atlantean models as well as single deckers of the period.

The engine took its name from the 600 cubic inch displacement and was a development of the 7.4 litre engine. It was used with a flexible engine mount which made it smoother and quieter than the 7.4. The 0.600 was teamed with an improved PDI transmission which included synchromesh on 2nd, 3rd and top gear and was the first heavy-duty synchromesh transmission used in a UK bus.
