450PS BMW M550d by VOS

In stock form with 381 PS (280 kW) and 740 Nm (546 lb-ft) on tap, the tri-turbo 3.0-liter six-cylinder has enough diesel muscle in standard configuration. For those very few with a thirst for more power, Vision of Speed is asking €2,290 to take the output level to 450 PS (331 kW) and 800 Nm (591 lb-ft).
