The BMW N55 engine is a turbocharged, direct-injected, 3.0-liter inline-six engine that was introduced by BMW in 2009. It was a significant evolution from its predecessor, the N54, featuring a single twin-scroll turbocharger instead of the N54's twin turbochargers. This design change resulted in smoother power delivery and improved fuel economy, while still delivering impressive performance. The N55 engine was initially offered in various BMW models like the 335i, 535i, and X3 xDrive35i. Its popularity and versatility led to its adoption in a wide range of BMW models, including the 1 Series, 2 Series, 3 Series, 4 Series, 5 Series, 6 Series, X1, X3, X4, and X5.

The N55 engine was praised for its combination of performance, efficiency, and reliability. It offered smooth and responsive power delivery thanks to its single twin-scroll turbocharger, which offered quicker spool-up times than the N54's twin turbochargers. The engine's direct injection system provided efficient fuel consumption and lower emissions. The N55 also featured a variable valve timing system, which further enhanced fuel economy and reduced emissions. Over the years, the N55 engine went through several updates and revisions, including the introduction of the N55B30A, which featured a modified turbocharger and an updated engine management system, further improving performance and efficiency. The N55 engine was ultimately replaced by the B58 engine in 2016, but it remains a popular and reliable engine choice for BMW enthusiasts. For those who own or work on BMW vehicles with the N55 engine, the BMW N55 Engine Workshop Service Repair Manual is a valuable resource that provides comprehensive information on all aspects of the engine, from maintenance and repairs to diagnostic procedures.
