The BMW M57 is a turbocharged, water-cooled inline six-cylinder diesel engine manufactured between 1998 and 2013 at BMW's facility in Steyr, Upper Austria.

Description

Incorporating common rail direct fuel injection, the M57 underwent two significant updates throughout its production lifespan. It was developed as an evolution of the earlier BMW M51 engine. The initial and TÜ (Technische Überarbeitung, meaning technical revision) models feature a cast iron block and crankcase, whereas the TÜ2 iteration transitioned to an aluminum design with redesigned combustion chambers. Injection pressures increased from in the pre-TÜ variants to in subsequent models. While magnetic injectors are standard across most versions, the TÜ2 OL and TOP editions utilize piezoelectric injectors.

Bosch provides the common-rail injection system and engine control units, employing the DDE 4 ECU for non-TÜ engines and upgrading to DDE 5 ECU for TÜ versions. Every variant is equipped with turbocharging paired with intercoolers: the 2.9-liter engines found in vehicles such as the E39 530d and E38 730d incorporate a Garrett GT2556V turbocharger; the 2.5-liter M57TÜ utilizes a Garrett GT2056V; the 3.0-liter M57TÜ is fitted with a Garrett GT2260V; TÜ2 models use a Garrett GTB2260VK; and the high-performance M57D30TÜTOP combines a BorgWarner KP39 high-pressure turbo with a K26 low-pressure unit.

Compression ratios vary between 16.5:1 and 18.0:1, with lower values applied to higher-output or twin-turbo configurations. Each cylinder is equipped with two intake valves and two exhaust valves, actuated by dual overhead camshafts driven by chains. The engine's maximum speed is capped at 4750 rpm.
