German tuner Hartge is preparing to launch their own power kit for BMW’s first tri-turbo diesel engine. Based on the popular 3.0 liter inline-six (N57D30), but with an extra turbocharger, the innovative powerplant produces, in standard form, 381 horsepower and 740 Nm (546 lb-ft) of torque.

The size, arrangement and interplay strategy of the three turbos are designed to guarantee maximum power delivery across a wide rev band. The system comprises two relatively small turbochargers and one large turbo, which join forces precisely to deliver the amount of power required.

According to the driving situation, the low moment of inertia of the small turbochargers is exploited to the full to deliver razor-sharp responses, while the link-up with the large turbo is maximized to generate as much charge pressure as possible.

BMW also engineered a new aluminum crankcase, common-rail direct injection with piezo injectors and high-pressure turbocharges with variable turbine geometry.

Harge amps up the power of the innovative diesel unit to 438 horsepower and 850 NM of torque. The Hartge tuning will be available for all six tri-turbo diesel models available, M550d xDrive Sedan and Touring, the X6 M50d and X5 M50d, as well as for the facelifted BMW 750D and 750Ld xDrive.

Pricing will be announced in the near future.

    Sweet baby jesus thats a lot of torque.

    438 and 850 (instead of 900-1000Nm in my opinion) still sounds enormous , what a machine..

  • mckillio

    I’ll take this in a V12 application, please.

    A possible alternative to the 2 smaller turbos is to instead just give the big turbo electric boost to spin it up when you want power immediately (no lag). Best if also the vehicle is a mild hybrid so that electrical energy is generated efficiently. This way you just have 1 turbo, less complexity.

      Electric boost? Turbos rev at 150,000 to 200,000 RPM sir.

        It would be hard to do wouldn’t it. Subaru is trying to do it I’ve heard
