The only reason Quad-Motor would be beneficial would be to provide hyper-efficient torque vectoring. If we were talking about a Rimac Nevera, torque vectoring without sacrificing power by using brakes might be worth the cost/weight/complexity of four motors, but we're talking about a pickup truck. A pickup truck with more than enough power to tow 44,000 lbs! Unless you're planning on using income from your racetrack winnings to pay for your CyberTruck, YOU DON'T NEED FOUR MOTORS!!!
Torque vectoring while rock crawling, or hill climbs in the snow, etc. will never need the maximum torque that any dual-motor CyberTruck can supply. Using the Sensify Brembo Brakes in a Dual-Motor set up should give you all the fine torque control and power you'll ever need.
When the Semi was revealed Elon told us that if the quad motored Semi had two motors fail during a job, two motors would be enough to complete the trip, still with enough power to outperform most diesel tractors. Now perhaps we should account for the possibility that that is only because the Semi would be using carbon wrapped rotors and differently ratioed gearbox that depended on ultra-high RPMs to achieve that torque, we're talking about 82,000 lbs loads. The CyberTruck will never need even a third of that power.
Yes, Elon did say there would be a Quad-motor CyberTruck, but he also said the Semi would have four motors too. When the reality of the capability of the motors becomes clear, Tesla has proven that they will depart from what they originally presented and go only with what is needed.
If they do stick with a Tri-Motor version I feel it will largely be for bragging points and wanting to avoid a bait-and-switch accusation the FUDsters will deploy. Three Model 3 motors will be well suited and sized to provide what the CyberTruck needs in the space available that Rear Wheel Steering will allow. If Tesla releases a Dual-Motor CyberTruck with as much range as the higher trims provide, I will step back from my Tri-Motor reservation to opt for the cheaper version (sink my savings back into $TSLA)
