The BMW N53 is a naturally aspirated straight-6 petrol engine which was produced from 2006 to 2013. The N53 replaced the BMW N52 and was released in 2006 in the post-facelift E60 5 Series.
BMW never sold the N53 engine in North American, Australian and Malaysian vehicles, due to the high sulphur content of the fuel available in these markets.[1] Instead, these regions continued to use its predecessor, the N52 engine.
The N53 is the final naturally aspirated straight-six engine produced by BMW, ending a history of continuous production of this engine configuration since the BMW M30 in 1968. The N53 began to be phased out following the introduction of the BMW N20 turbocharged four-cylinder engine in 2011.
There is no BMW M version of the N53. The BMW N54 turbocharged straight-6 engine was produced alongside the N53.
