The Problem With Tesla's Differential Strategy

First half is how a differential works. 2nd half comes to the conclusion that cost is the constraining factor.



$500-1000 on top of the cost of a three motor Cybertruck doesn't sound onerous to me. He doesn't mention that Jack Rikard [RIP] acquired the North American franchise for the Quaife torque sensing differential for the Tesla Model S. It's on the EVTV catalog: EVTV Motor Verks Store: Quaife ATB Limited Slip Differential for Tesla Model S, OEM Electric Vehicle Items, QuaifeATB.

Their $1,795 list price tracks with his $500-1000 estimate.

I'd been following this guy on his 3D printer videos, now I have discovered his CyberTruck content.

The Tesla CyberTruck Is So Much Better Than I Originally Thought!

The first 10 minutes is on the structural shell, then on to 'it drives itself!'. The thing [I believe] he misses is that the inside of the four wheelwells are same as the outer shell, not the stamped inner pieces. Making each corner a monocoque box.

I may be wrong about that, but I don't care I based my CyberHaus design on the principle.

youtu.be/4TQH_Fv4inU?t=1154. He decides that it will have independent suspension and not the solid axle he thinks a truck requires. Apparently not aware that Rover figured out in the 60s or 70s to put a slip joint in their De Dion axle so they could leave them out of the axle shafts.
