Design, development and variant notes
The M73 enlarged the M70 to 5.4 litres and introduced roller-rocker valve actuation while retaining a single camshaft per bank and two valves per cylinder.
The article describes two Bosch engine-control units coordinated with a Siemens EML throttle controller. The later technical update added emissions and cooling changes, including electrically heated catalysts.
