    Hey guys,

    as most of you know, Tesla uses components of different manufacturer as Mercedes or Land Rover .

    Does somebody know who produces the drive shaft of the Model S? I can't believe that such a common part is really just made for the Tesla. I'm especially interested in that part that is connected to the gear box.

    Many thanks!

    I'm not sure but that's got to be one heck of a strong part to handle the amount of torque in the P85D! I think about the drive shaft often when doing launches. 0-60 with all that weight must be a tremendous strain. I wonder if a future model may take advantage of carbon fiber driveshaft technology like the BMW M4? Good way to save weight.

    I'm surprised we haven't seen broken driveshafts....

    i suspect it's teslas own development, seeing how many problems they had with the roadstar's driveshaft.

    I am not aware of problems with Roadster driveshafts. There were definitely problems with the original Roadster 2-speed transmission, which was abandoned and all early production Roadsters were retrofitted with single speed transmissions.

    The trick with carbon half shafts and drive shafts is the joint to the splines which must be steel.
