The BMW N73 is a naturally aspirated V12 petrol engine which replaced the BMW M73 and was produced from 2003-2016. It was used in the BMW 7 Series (E65) and Rolls. There are four distinct versions of the N74, all with varying displacement but largely identical technology.
Compared with the predecessor N73, the N74 uses the same direct-injected DOHC VANOS design, but eschews Valvetronic (BMW branding for variable valve lift) in favor of twin turbos mounted outside of the V. N73 6.0 V12. Design The original M70 V12 entered production in 1987 and didn't change much during it's 16 year production life.
It never incorporated the technologies used in other BMW engines from the same period. So the N73 was a big jump forwards in that regard. It finally used four valves per cylinder and one coil per cylinder.
Over time, BMW had four V12 engines in production series cars: the M70, M73, N73 and N74. But it's the latter which will hold a special place in everyone's hearts. The N74 was the first.
Though the S70B56 didn't sell in the same numbers as the M70 (some have called it the forgotten BMW V-12), the M division did take another swipe at the first-generation BMW V-12, starting with the S70/2, the engine that it built after fielding a request from Gordon Murray for an ultra.

The BMW N73 V12 powered the E65/E66 760i and later Rolls-Royce models. Here's what makes it special, what fails, and how much tuning is realistic. The BMW N73 is a direct-injection 12-cylinder V-twin gasoline engine that was produced from 2003 to 2016.
The BMW N73 replaced the M73 engine, and from 2008 it was gradually replaced by its turbocharged successor, the N74. The N73 was the world's first production V12 engine with direct fuel injection. The BMW N74 is a twin-turbo V12 petrol engine which replaced the N73 and has been produced since 2008.
It is BMW's first turbocharged V12 engine and is also used in several Rolls. The BMW N73 is a V12 DOHC piston engine which replaced the M73 and was produced from 2003-2008.
