This range of 2.5 and 3.0 BMW 6 cylinder, twin camshaft 16v. gas engines, were launched in 2004 and are the most widely used engines in BMW 3 and 5 Series models.

There are 2 engine types within the range N51/N52/N52K are valvetronic engines. The Valvetronic layout incorporates a conventional inlet camshaft and a secondary eccentric shaft, with intermediate levers and followers, activated by a stepper motor. The stepper motor changes the phases of the eccentric shaft, altering the action of the inlet valves. N53/N54 are direct injection engines.These engines do not have the Valvetronic system. All N51/N52/N53/N54 engines have VANOS variable valve timing units on both the inlet and exhaust camshafts.
