Range Extender Battery Pack increases range to 470+ miles and costs $16K 🔋

[Crissa]

You have got to be kidding me. Looks like more than 1/3 of the bed. Decreased payload. At $16K! Frankly Tesla should have gone with a software locked extended battery. While not a 470 mile range, say 390-400 miles would be better than this bizarre (stupid) option.

Software locked lump in the bed?

If I understand you correctly,
then you believe they had room in the base battery structure for more cells
but what if they did not have room for more cells (ie. > 123 kWh worth)
so they must have felt they could do nothing OR find their_deemed_best_location.

Should be no problem tossing that in the back. Although it’s probably a bit lighter if it’s 4680 cells. I think they said 16% weightb savings. So maybe around 700+lbs.

The weight savings of the 4680 cells do not apply to bulk storage. The expansion battery isn't replacing structure.

Anyhow. I was paying attention. No one from Tesla said they'd miss the range on their top-tier model. We did get warned they wouldn't hit their price target.

They missed it by a rate several times larger than inflation, tho.

No, main battery pack, like Tesla did with the Model S years ago.

The Cybertruck has larger 4680 cells. I do not know if Tesla could stick more in the main pack. Maybe the 4680 cells are not as energy dense as Tesla had hoped. Maybe it’s a manufacturing yield issue, but something happened in the Cybertruck development that caused Tesla to settle for this inelegant and stupid solution. I need the entire bed and I need at least 400-450 miles of range. Have a Silverado EV reservation.

Looks like the top of the extender is finished like the bed floor, and there is quite a bit of space above it before you reach the bed cover. So you don’t truly lose 1/3 of the bed, you just lose 1/3 of a consistent flat bed floor.

Seems like either you have a certain view of what is “quite a bit” of space, or you’re not quite understanding the geometry of the bed

the bed floor to the top of the rear window is 28”, while the tailgate end of the bed is 19.8” high. The tonneau track and tonneau etc eats up 1.5” off the topmost height.

So ~26.5” headroom max at rear window, with ~18” headroom at the tailgate

the extender comes up to the L-track, so is about 16-17” off the bed floor

that means that at the rear window, there is ~9.5” above the extender, at the rearward lip of the eave about 8.5” over the extender, and at the rearmost edge of the extender ~7”

basically, over the extender, there is a wedge-shaped void that’s is

51” wide X ~30” deep with a height running from 9.5” at its high side ~9.5” tall and low side around ~7” tall

Sthere space there? Yes.

Is there “quite a bit”?

I mean, there’s space for this tent:

meanwhile, folks shouldn’t be fooled by Musk’s off-hand comment that it only takes up 1/3 of the bed, as being about the depth it reaches into the bed

to your point, I believe he was at best referencing taking up 1/3 of the VOLUME of the bed

that extender reaches back into the bed closer to 1/2 than it does 1/3

I expect it’s right at about 35” back from the 6’ mark at bed floor, so leaving ~38” between the extender and the tailgate

Those are just volume and dimension stats.

in terms of utility, I think it reduces the bed’s utility by half to 2/3rds depending on use case

I suspect that the battery-in-the-bed range extender makes it DOA for most due to losing so much of the bed function.

And yet, some were clamoring for a fifth-wheel configuration, which similarly nerfs the bed space ?‍

5th wheel hitches are made to be removable, but I doubt the range extender will be.

Interesting. In my line of work you say what you mean and what you intend and you deliver exactly that or more. In my experience there are lines of work where that is not the case, and they routinely refer to themselves as intelligent. I had no right to think that Elon Musk could deliver what he said he would deliver but I won’t make that mistake again.

I am really curious about your line of work!
I dont know a single industry in US that doesn't overpromise and then under-deliver

I followed the Silverado EV and watched a several youtube videos from their showcases that let people tow/drive them. There have been some good interviews with engineers as well.
I think it will do well if they can produce them as they meet the spec's they claim.

Not sure if you've seen other threads here with videos and discussions (example):

Here is my spreadsheet that I've continually updated as I've gathered more details.

That Rivian Max miles/kWh doesn't make sense.

Every fifth-wheel hitch I've seen bolts to the bed floor, not easily removed.

The point I was making is that people who need towing need towing, people who need hauling need hauling, and people that need both at the same time are shopping in the wrong vehicle class.

All the ones I've seen and used are easily removable with 4 pins in the bed. They're heavy (130+ lbs), but doable.
