Slight tangent but what are you getting for $20K? Is it a software feature, or is there physical difference between the normal performance and "Ludicrous" model

Slight tangent but what are you getting for $20K? Is it a software feature, or is there physical difference between the normal performance and "Ludicrous" model?

There is a smart fuse composed of an inconel alloy that is pyro-actuated to protect from overcurrent conditions when performing a Ludicrous launch (~1500 amp peak current drawn). It's not software only. Very fancy circuit breaker.

  It's that the same as a Flux Capacitor?

  Do we know if that's needed with the new drivetrain?

  Interestingly, it seems SpaceX got to play a role developing the alloy https://en.wikipedia.org/wiki/Inconel#History https://en.wikipedia.org/wiki/Inconel#History

    Inconel is just a group of nickel alloys, been around for years. No indication the specific alloys spaceX has developed are being used in the fuse, although they could be, however, wikipedia indicates they are used in rockets.

      Fair point, but it seems that SpaceX business is spreading genes to the car industry.

  Honestly this sounds like /r/VXJunkies is leaking...

    I've been having issues with my transmission's cardinal grammeters going out of sync. I've heard if I get a turbo encabulator [0], it would supply an inverse reactive current into the unilateral phase destractors, which would fix the sync issue, but the price tag is more than I can swallow. I might just have to deal with the side fumbling of the ambifacient lunar waneshaft, even if it means having to regularly replace the spurving bearings.

  I am 80% sure this is a line from NCIS.
