At the same time as the A55 Mk II became the A60, it was given the option of a small diesel engine, a unit which was actually a beefed-up conversion of the B-Series petrol engine. At first this was an export-only model, but from summer 1962 it was made available on the British market.
As you might expect, the A60 Diesel was a much slower, noisier, rougher, but more economical car than the petrol-engined version, and for all the obvious reasons it sold very slowly indeed. Most of the cars built were used as taxis, or for similar commercial ventures, and very few survive to this day.
Only Austin and Morris cars were available with a Diesel engine.
