Design, development and variant notes

The N54 uses two turbochargers, direct injection with piezo injectors, double-VANOS and an electric water pump; it does not use Valvetronic. BMW's 'TwinPower Turbo' marketing name should not be read as a universal turbocharger count across different engines.

The initial 225 kW version and later higher-output applications have distinct calibrations. Alpina also produced modified versions with changes including cooling and internal components.
