Yes, very possible (2.9 that is, not 1.9). I did a few calculations in another post here and it all sort of comes together. If you are going to pull 14000 pounds up a fair grade in reasonable time it takes a lot of torque to get that weight plus the weight of the truck moving. Take the trailer off and the truck still has the torque and is going to accelerate pretty darn fast.

Yes, the torque transferred to the road is a function of slip so indeed a lot of rubber is going to be left on the road - if you choose to come out of every traffic light and stop sign at 0.94 g.

Forgive me for not knowing this but when I read that Tesla may be coming out with a Plaid Cybertruck I was thinking "Tartan? that wont look good at all!." Can someone explain to me what this really is? Thanks.
Spaceballs the movie.
It's a spoof on hyperspace jumps from Star Wars. Their ship goes to plaid, they went so fast. Great film. Time for a rewatch.

You may be right, however Tesla's current dual motor options are not synonymous with ludicrous. It may be that the tri motor CT will have a "plaid" setting for acceleration, although I doubt it. That will probably be reserved for the roadster and maybe the S/X.

In the very least, the tri-motor will be a prerequisite , other things may be added, better breaks, software tweaks, perhaps a special configuration to the power train to increase the power output, can't wait to find out.

Undoubtedly. Currently the maximum draw out of the batteries in the new update for S/X is about 615 kwh. I imagine that would be plenty to get a tri motor CT up to 60 in 2.9. I have little doubt that Tesla will figure out a way to draw the energy out even quicker as time goes by, maybe even by the time the CT comes out.

It plays into Spaceballs and the Ludicrous speed. If you haven't watched the movie Spaceballs I totally suggest you do.

Undoubtedly. Currently the maximum draw out of the batteries in the new update for S/X is about 615 kwh.
Curious as to where you got that number. Assuming the X weighs 2500 kg and is torque limited up to 60 mph and power limited beyond that the draw at 60 (reached in 4.4 sec) would be 409 kW.

I imagine that would be plenty to get a tri motor CT up to 60 in 2.9.
Assuming the CT to be heavier than the X at 2700 kg it would take 670 kW max to accelerate it to 60 in 2.9 sec.


I have little doubt that Tesla will figure out a way to draw the energy out even quicker as time goes by, maybe even by the time the CT comes out.
409 kW from the X's 100 kWh battery represents a discharge rate of about 4C. 670 kW would represent 6.7C from the 100 kWh battery in the X. But assuming the TriMotor will have a battery about twice as big as the Xs that 670 kW draw would only represent about 3.4C. IOW I think they have already figures this out.[/QUOTE]

There is a video of a guy who hooks up one of those aftermarket Tesla readers and his tops out at about 615kwh after the cheetah update. The current Model X is rated by Tesla at 2.6 to 60. That’s with a dual motor configuration. The CT will be heavier no doubt, but I’m not sure where you got your calculations. I’m sure 615kwh draw will propel the tri motor CT to 60 in 2.9, Elon wouldn’t have said it if it was patently false. Elon stretches the truth in other areas, but not performance.

My bad the, the video shows the internal read outs in the Tesla hitting 614kwh max draw
