Cybertruck just did 185.8 mi in 90+ degree temps using <50% of battery

[carsly]

downhill.

Gemini calls it ~150 of elevation difference. So yes, nominally downhill I suppose over 180+ miles.

"Therefore, the elevation change between Silver Spring, MD and Princeton, NJ is approximately between 141 and 151 feet, meaning Princeton is lower in elevation than Silver Spring. "

Drove for 3.5 hours today, covered 185.8 miles from Silver Spring, MD to Princeton, NJ. Highway speeds with one 10 minute slowdown. AC blowing cold on a hot day.

Was stunned to find that I used only 48.2% of the battery. Doing the quick math, that means in the dead of summer it's possible to drive a Cybertruck AWD on 35" all terrains at highway speeds for seven straight hours covering 370 miles before stopping to charge. What the what?!

Yep, I get similar results in the summer at those speeds.

This likely means is that we have better throttle control than the people who can't even get close to that (or you are making good use of FSD). Some people, for whatever reason, are very inconsistent on the throttle and can't seem to hold a steady throttle for the life of them. They have very crude inputs to the throttle pedal. That kills efficiency far more than some people seem to realize. Because they are going into regen when they shouldn't be.

Other people think they are running the correct tire pressure if they look down and see the TPMS reporting 50 psi (in the warm part of the day, and/or after they have been driving for 30 minutes). They think, "Oh, my tire pressure is close enough so I can just procrastinate another month", not realizing they might be 5 psi below specifications (or that 5 psi even matters).

These types of people come on the Internet and complain about poor efficiency, as if it's the vehicle's fault they can't provide consistent throttle input, or that they don't know what "50 psi cold" actually means. The Cybertruck is a driver's truck, and a high-performance one at that.

I've even seen idiots with less efficient aftermarket tires that have terrible rolling resistance complain that Tesla lied about the range. It takes all types, I guess.

Looks like a slight tailwind, at a angle, for half the trip and a similar headwind, at an angle, for the other half of the trip. Was on the road from around 10:45a - 2:15p

I can't get 150 miles out of 300 miles charge.

You must live in the mountains, or have a lead foot, or both! How quickly you going through tires?! Have you tried chill mode?

You're spot on regarding throttle control and tire pressures, I always check and adjust cold pressures before any long trip and check every few days in the display out of habit. I think my cold pressures this time were 51-52 PSI across all four tires, some of that variation could have been because I wasn't parked on a level surface.

And FSD did 95+% of the driving, it's gotten much, much better at throttle control. I remember the first version for Cybertruck at the end of September was all over the place. This was very, very smooth. I was on chill and relaxed FSD with lower ride height.

Interestingly, tire pressures do not change with added cargo or the tilt of the parking spot.

What happens is more weight on a tire increases the size of the tire's footprint, but the pounds per square inch remains a constant, unless you add or subtract air or the temperature changes.

Wow, my efficiency in summer goes waaaaaay down, but I keep the AC at 70°. Maybe I should turn off the seat heater?

Cybertruck pulls more power than my house AC (3 ton?) when initally cooling down. >6kW vs ~4.

Regarding weight, it does change, but not significantly. Turning more of the tire from a torus to a rectangle at the ground contact point reduces the volume thus causing an increase in pressure.
Similarly, tilt redistribute weight; but again, minimal impact.

Florida. 70 mph. 70 AC
My S has 230k miles. Im not a rookie Tesla owner. My 100D got 225 easy

I usually start the climate before leaving the house ("Alexa, start the truck!") so that the AC pulls from shore-power, as I'm typically plugged-in.

Yep, that's how I measured it.

That explains how the Cybertruck can chill so quickly on a hot day! And as someone who prefers cool temperatures, I love that!

If you're not towing, who needs a bigger battery? BTW, I did have crossbars mounted, one passenger and luggage for two of us (along with a full-sized spare) all cutting into my efficiency.

I took a screenshot of your video to look at your trip display. The two things I noticed were, how smooth and flat your trip appeared to be, since there were almost no wiggles. And two, you can check the elevation figure of -0.7%, so a tiny benefit.

And if you look to the far right, you can see it says there was a 2 mph wind, and it helped 1.7%. Great result!

 

[Sousray]

Yup, I also get similar milage on mine. Set for relax, chill, lower height and I am getting 360-370 range based on my driving back and fourth to work 40 miles one way at 60-65 mph and some city traffic. I average 335 - 345 kw/mi in most trips. Definitely do not have a heavy foot.

Gravity always wins..

If you keep the CT at or under 70 pretty consistently, you should be getting great efficiency. It really starts falling off a cliff there and 80+ is a pretty large hit. Second factor is temps... and more cold than hot. These cells like to be >50f and close to 70-75f (truck will attempt to heat the batteries to at least 60 if you're not in chill mode). Hotter doesn't hurt them (to a reasonable level), just causes some extra AC usage. Cold has the truck heating the cabin, but also putting a ton of heat into the cells. If you are cruising under ~70 and the temps are >50-55f, you should get very good efficiency.

TLDR this trip hits the major factors, warm but not overly hot and not high rates of speed. Plus a slight wind boost. Though where I'm at, I'll never see below 2 mph winds. It is a nice day to be under 10.
