Driving Model X 200 km/h, 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).

The supercharging speed right after the run was at normal speed. No reduction due to heat.

  1. Just a Question

    It's funny how much people bitch about distance. If you have a car that can drive 400-600km on a full charge and that charge can be replenished the second you aren't driving, so you can drive for 4-6 hours straight at 100kmph…if you're driving 4-6 hours at highway speed without a break, every day, you fucked up on home location.

    I wish we had autobahn roads in the UK, they're so wide and straight compared to ours. You won't find 100km of uninterrupted motorway anyway here. You'll be lucky to go 70mph for more than 10 miles at a time.
