for all the talk of musk being nothing more than a salesman, con artist and charlatan... i desperately want a truck that is all stainless steel. the salt is brutal where i live. and almost everyone i know wants a truck that wont be hobbled by complicated emissions equipment. try driving across Nebraska in a snow storm when the engine shuts itself down because a diesel emissions sensor, totally unnecessary for the actual operation of the truck, stops working correctly. for all the mud people sling, hes offering something that a lot of people desperately want and that the established players refuse to deliver.

Let's just hope the truck is better about the cold than the 3 is. I am quite tired of the snowflake icon and the helpful battery gage telling me how much power I can't use because it's too cold out.

How does it to in extreme heat?

yes, one of the weakest points of EVs in general. the new developments in thermals, namely the unification of the thermals and bridging of all thermal systems, stands to take a pretty big bite out of that. not to mention the heat pump. vacuum panels integrated into the pack could make it a non-issue, although i havent seen any talk of tesla doing that. for me, i would really like to be able to have a generator on board not only to extend range but also provide peace of mind for blizzards. the nice thing about that setup is that when the complicated machinery in the gas engine stops working, i can just take it off and put a new one on. or use it to power a jobsite. if the cybertruck would allow you to charge while moving, im not sure i could justify buying anything else for my personal situation.

Just curious, but what percentage (roughly) does your Tesla battery degrade with cold temps?

I tracked energy consumption (Wh/km) averaged over the time I had winter tires installed on my M3 (when temps hit 7 C or lower) and consumption was up by 20-25%.

I would have thought that, once you started moving, the battery would warm itself up and the full power would be available. Is that not the case?

I suppose that might not help if one's main use case is a lot of short, interspersed trips on very cold days. How long does it take for the battery to warm itself up?

While F150 lighting isn't stainless steel, they are made from aluminum alloy, pretty good against rust.

the chassis is aluminum? im pretty sure its steel

steel frame.

If you live in an area with harsh winters, your battery will degrade faster than usual. Do you want to a frame which is going to outlast an obsolete vehicle?

cold weather causes the battery to self-discharge at a higher than normal rate, not degrade or become damaged. but i would be happy to upgrade my pack, all of which are designed to be swapped out easily and even quickly enough for re-charge by swap in some models, when the next quantum leap in electrolyte chemistry comes along.

Opposite is true for leaf sans cooling in hot climates…

Fair enough. They are two different construction. That being said, F150L has V2V/V2H charging, so that might be useful for a lot of folks who live in areas where infrastructure isn't amazing.

Where did you see V2V mentioned? Or are you assuming it's possible due to the normal plugs? The V2H charging is an extra $7500 (included in the platinum model) for the interconnect to your house.

Plastic is the best against rust.

And worst against sun
