Below is an introduction to the N52 engine: BMW's N52 engine (including N52B25 and N52B30) is a glorious engine series, which is an inline-six cylinder engine, hailed as one of the best inline engines in the world and one of the best inline engines in history. To reduce weight, the N52 engine was the first to adopt a magnesium-aluminum engine, and it is also the last generation of civilian magnesium-aluminum engines. The characteristics of the N52 engine include an aluminum-magnesium alloy cylinder block and composite crankcase, second-generation Valvetronic, a three-stage variable valve device, and a dual camshaft variable valve timing system. There are many models equipped with the N52 engine, such as the E90's 325i/330i, E60's 525i/530i, E65's 730i, E70's X5 30i, etc.
