The N55 3.0 Twin Scroll Single Turbocharged Inline Six engine was BMW’s replacement for the notoriously troublesome N54 Engine, which was swapped out in 2009, this engine would be one of the most commonly found engines within BMW’s line-up for the next 9 years and could be found in nearly all models ranging from the 1 Series to the X5/6.

The N55 Engine was found initially in the 335I of 2009 with just a touch over 300BHP this engine was revised multiple times and can be found with 365BHP in the BMW M2 N55 Up to 2018, this engine can be a rival for the likes of Audi’s 2.5 5 Cylinder lump found in the RS3 with similar power capabilities.
