Driving Model X 200 kph/125 mph for over 100 km/60 mi

.

Many people claim that a Tesla can’t drive at high speed for many minutes without overheating. This is not true. So I prove that it can be done. After 28 minutes, I started seeing dotted line. This is probably due to battery overheating. The stators would overheat much quicker if I did full accelerations.

After the run, I calculated a whopping 7 kWh heat loss that was not counted in the trip meter. This was due to battery and motors heating up due to high power output. So the real power consumption was actually 630 Wh/km, 1014 Wh/mi.

Based on past tests, it seems like the optimal speed to drive between superchargers with a Model X is 140-160 km/h. At higher speeds, air resistance and heat loss is too high compared to the supercharger speed. And it also means that you have to charge to higher SoC in order to reach the next supercharger (which is slow).
