Cybertruck Highway Range Test by Out Of Spec

[Supratachophobia]

Don't forget the tonneau blocks that physical view out the back of the truck.

Details details. It's feature complete for Space-Karen. Onto the next shiny thing.

I can't imagine Tesla ignoring this one because it's a critical safety issue in the CT due to the fact that the tonneau completely covers the rear cabin window and 100% obscures the physical rear view mirror. Couple that with the huge blind spots the "sails" on the bed sides create and you have a really poor visibility situation for changing lanes,etc.. especially in dark, rainy conditions.

As someone who drove a service van without a back window for years the safety aspect of this is a little dubious. If you count semis most vehicles don't have a rear view and rely on side mirrors to operate. Sure its not as good as having the view but you can drive to overcome it.

That's true, but people who drive semis have to get a special license to do so and Tesla also deliberately made the CT so the side mirrors could be removed based on personal preference.

I used to drive a 26' box truck doing furniture deliveries and without side mirrors I would have been literally blind backing up. Same thing with your van. Or a CT with the tonneau down, dirty camera and side mirrors removed.

Saw this in the CT thread as well...

" I went from 2.05 miles/kwh to 1.72 changing from 21" road tires to 20" ATs on my R1T. "

Did you remember to unhook the 30' Airstream from behind your Rivian for the 20" tire range test?

Yep, that's me. I attribute a little lower efficiency due to a lower wheel offset. Tires track much wider than stock. Like I said, I don't think 2.01 miles/kwr is all that bad for the CT, compared to a smaller, narrower R1T.

It's hilarious that Tesla can't get efficiency better than an R1T despite looking significantly uglier. I thought efficiency was a big part of the rationale for the whack job design.

For a full size truck it is pretty efficient, the Cd is way lower than the Lightning & way way less than the Hummer

My R1T with AT tires has been averaging around 1.9 mi/WH at highway speed during winter ( 30-50 deg) here in Colorado. That translates to sub 250 miles( assuming 130 usable kWh pack).
Kyle got 2.1 with CT which is not bad. Rivian has a bigger battery pack while CT has a heat pump. My R1T got 1.6mi/wh driving up to MTN and back in cold weather ( 2-20 deg) It sat in a cold parking lot for 5 hrs. Love to see extreme cold weather range testing with CT. I usually take model X when I take a trip to Vail. Its efficiency only drops about 15 % in very cold weather. Tesla’s Supercharging network also gives me a peace of mind. Rumor has it that Rivian is working on its version of heat pump. A bigger batter pack with better thermal management should give Rivian range advantage over CT.

Is that 1.9 mi/kwhr an average of road trips or just day to day driving? In cold weather, short trips will typically be less efficient because the battery and cabin heating are a more significant portion of the energy use. I also assume you aren't running in conserve mode around town?

 

[srnyoung]

In the Elektrek writeup of the efficiency you can practically hear the Teslastan's world crashing down around him... So many tears in his CyberBeers...
"Electrek’s Take
That’s not great. I would have expected closer to 270 miles at that temperature.

Now, I am really worried about how the Cybertruck would perform at a temperature below freezing, like we have now in Quebec, and when towing any kind of significant load.

To me, it looks like Cybertruck would be somewhat limited in its capacity to be used as a work truck without the extended range pack, which itself also reduces the bed – a very useful part of a work truck."

 

[Rivian Head]

My Quad R1T with AT tires in Conserve mode in highway at 60-70mph to Mtn and back for about 160 miles distance would average 1.9 in 40 deg temp. I will get 2-2.1 mi/ wh in the summer. In single digit temp, it gets 1.6 after sitting in a cold ski parking lot for 5 hrs. So it’s about 30 % drop in single digit weather. It’s a significant drop. Likely will improve with heat pump and better thermal management.

 

[KootenayEV]

Well then you can assume the same truck on 35" ATs would fair worse. FWIW I always averaged in the 1.8 range before the camper, more like 1.6 these days and even less with my Nokian winter tires.

Interesting about the tires - I did some efficiency tests the day I swapped tires and came to the conclusion that the Pirelli's and the Nokian Hakka LT3 studded were the same (tested on same wheels). I'll eventually get a blog post with better deets together.

Different wheels too in my case, also probably normal winter efficiency losses from running the heater.

Kyle/OOS posted another video:



TLDW:
- CT is composed, competent
- Some interesting behaviors with steer by wire, both good and bad
- CT had some vibrations at speed, which they weren’t sure where it came from
- R1T performance driving seems better than CT, as R1T seems to have more predictable steering and you can turn off traction control
- R1T interior feels very welcoming in comparison, though CT seats might feel better

 

[HaveBlue]

CT getting 2.05m/kw is great. I only got 1.62m/kw this last trip.

They must have been towing a smaller trailer than me.

 

[LL75]

2.46 mi/kWh over the 14k miles I’ve driven on 21s, mostly around town with several long (1000 mi) road trips in conserve. Mid-Atlantic. Just a datapoint.

edit: photographic evidence

Nice, i'm at around 13500 miles with 2.32 mi/kwh with 21" as well and about 1500 miles in conserve mode
