The BMW M73 is a 60° V12 SOHC piston engine which replaced the M70 and was produced from 1993-2002.
Compared with its M70 predecessor, the M73 features increased displacement thanks to increased bore (85mm up from 84mm) and stroke (79mm up from 75mm), and an updated roller-rocker valve-train.While most other engines in the BMW range had switched to DOHC and 4 valves per cylinder, the M73 used SOHC and 2 valves per cylinder.
Some versions of the engine have two separate Bosch Motronic ECUs, while others use a single Siemens ECU.
