I created this spreadsheet to help me design some EV conversion projects, but it can be used to fill in the blanks to infer missing Model 3 specs from known public data.
I've assumed a slightly more conservative max motor RPM than the S, viz 16000RPM, which implies a final drive ratio of 9.34:1 on the 19" wheels for 140mph top speed.
Also implies a motor torque of about 330Nm, motor power ~ 225kW for a 5.5s 0-60.
Battery must be around 60kWh for drag of 0.23 and frontal area of 1.9 (cf BMW model 3) assuming same tyre .
Battery needs about 30 2170 cells in parallel to get a 4C 600A+ discharge rate required by the accel curve
Kept the modules /pack at 96 to maintain the same motor voltage cf the Model S
Predicts a 0-100 mph time of ~11s, and about 24s to reach 140.
Make a copy of the sheet and have a play, see what you can find out!
