A recent dealer presentation in the Netherlands has revealed some further specifications and more concrete evidence for BMW's long rumored 5-Series diesel from M division.

According to the leaked specs, the tri-turbo six-cylinder diesel will benefit from 381 PS (375 bhp / 280 kW). Although this doesn't sound like M division territory, the torque figure of over 700 Nm (516 lb-ft) makes it a viable alternative to the BMW 550i with 408 PS (402 hp / 300 kW) and 600 Nm (440 lb-ft) of torque.

Officially, BMW has yet to confirm the model representative of a diesel M5. However, M division's global marketing manager, Brian Watts has previously confirmed the model is under consideration.

In light of this new information, speculation abounds about the M550d being offered in both F10 sedan and F11 wagon variants. Furthermore, the tri-diesel engine could also find its way into the X5M/X6M SAVs.
