    • N63TU V8 breaks into the 10's on factory turbos - BMW F06 650i Gran Coupe runs 10.98@125.09 1/4 mile tune only

      A 10-second factory turbo N63TU 4.4 liter V8? That is exactly what we have here with a BMW F06 650i Gran Coupe breaking into the 10's with just a tune. What makes this even more impressive is that it was done with the heavy F06 Gran Coupe variant of the 6-Series.


      Keep in mind this is an N63B4401 motor known as the N63TU or N63 Technical Update. This is not the newer N63B44T02 or N63TU2 from the G12 750 and G30 M550 xDrive models.

      The slip unfortunately was not posted but you can see in the video the 650i Gran Coupe does indeed post a 10-second time.
