The BMW N52B30 is a highly regarded naturally aspirated 3.0-liter inline-six engine, known for its exceptional smoothness and reliability.
As a significant successor to the M54, its key innovations include a lightweight magnesium/aluminum composite engine block, BMW’s Valvetronic variable valve lift, and Dual-VANOS variable valve timing. Depending on the vehicle and tune, power output typically ranges from about 215 to 268 horsepower.
Higher-output versions utilize a three-stage DISA variable intake manifold for enhanced performance across the rev range, solidifying its reputation as a beloved and efficient “last-of-its-kind” naturally aspirated straight-six.
