Tesla Model X Plaid (tri-motor)
95 kWh usable, peaks at 245 kW. Every figure below comes from the same engine as the calculator, run on this car's own charge curve. Charge curve estimated from published charging reports, last checked 2026-09-14. Not independently dyno-verified.
Fast charging, 10% to 80%
DC intake power against state of charge, 0 to 100%.
Highway range
The 80% to 10% window is the range most drivers plan a road trip around: you rarely arrive at a charger empty, and you rarely wait for 100%. Cold weather costs range twice, through denser air and the cabin heater; the 20°F figure has both.
This is an estimate: there is no published road test of the Tesla Model X yet, so it comes from the car's mass, drag and frontal area with the fleet's typical calibration. Scored that way on road tests it never saw, the model lands within 9% for the median car and 34% at worst.
Where these numbers come from
Tuned against public real-world 10%->80% reports (129kW average, ~31 min, up to 250kW on a warm pack near 10-20% SoC tapering to ~130-150kW by 50% and ~80-90kW by 80% - shares the base AWD X's pack - simulated 30.5 min at 131kW average) - no named benchmark in the spec.
The charge session is integrated across 1% state-of-charge steps on the curve above. In each step the rate is the lowest of the car's curve, the charger's power, the charger's current times this 400 V pack's voltage, and a cold limit that lifts as charging warms the pack. Highway range is road load: rolling resistance on 2,450 kg, drag on a 0.24 drag coefficient and 2.75 m² of frontal area, the always-on electrical load, a cold penalty and a cabin heater that works as hard as the weather asks (239 Wh/mi at 55 mph and 72°F). Formulas and their limits: how it works.
Pack age matters. These figures assume a new pack. The calculator takes a model year and odometer reading and derates both charging and range for an older one.
