1998–2008•6 cyl•Longitudinal•Aluminium / Cast iron
The BMW M57 is a 3.0-liter, straight-six diesel engine produced from 1998 to 2013. Renowned for its exceptional durability, smoothness, and massive torque, it became a staple across BMW sedans, wagons, and SUVs. It features high-pressure common-rail injection and ranges from 148 to 282 horsepower.
Features
- Engine Block: Early versions used a highly robust cast-iron block, while later revisions shifted to a lightweight aluminum block to reduce weight.
- Cylinder Head: Features an aluminum 24-valve, DOHC (Dual Overhead Cam) design.
- Fuel System: Utilizes a highly efficient common-rail direct injection system that optimizes fuel atomization for better power and emissions.
- Turbocharging: The engine underwent several updates that progressively upgraded the forced induction system, moving from single variable-geometry turbochargers (VNT) to highly responsive sequential twin-turbo setups.
