Tesla unveiled Tuesday at its Battery Day event a new 4680 battery cell, a larger form factor that would increase range by 16%. Tesla said the new cells will have a 5x increase in energy and a 6x increase in power capacity. The new cell is 46mm by 80mm, featuring a “tabless” design that enables the...

Other companies are still trying to figure out how to get batteries for their prototypes while Tesla just figured out how to change the entire game. Range increases 16% from form factor + 20% from anode and 14% from structural battery. That puts a model 3 at 495 miles.

The total range increase is 54%!

I will freely admit to not understanding the computation that shows such an increase in range (the stated increase ought to give a 300 mile range auto another 50 miles or so of range??). My intent is to order our MY in Oct (long story as to why then). I was hoping for a longer range vehicle then is now the case. Not sure that's going to happen.

No, it won't happen for your MY. Probably not for any MY because the improvement is for a new form factor, tabless battery whose factory is at least a year away from volume production capability. Very likely that the battery pack design would not be compatible with M3 or MY, in the same way that MS and MX are still using 1650 batteries instead of 2170.

How do you propose they get to 520+ miles on the Plaid Model S then? I doubt having an extra motor is going to provide more space to cram 1650's into it.

I believe the 54% range increase is mostly related to power efficiency. The regular Model S LR+ has a 100 kWh battery pack with an EPA combined 117 MPGe (29 kWh/100 mi.). The Plaid Model S may have the same equivalent 100 kWh battery pack with an EPA combined 180 MPGe (19 kWh./100 mi.).

I think the main takeaway from the entire presentation is:
16% increase in range based on battery design alone (read: better cell geometry = more capacity). Also important is this is not vaporware... these are batteries being produced, right now, at a scalable prototype facility. A ~50% increase in power transfer rate due to tabbed design (i.e. improved thermal characteristics) (read: decrease in charging time) while not directly stated in the presentation the insane power output of an electric vehicle is merely a direct correlation of a battery's ability to discharge at the same (or greater) rate that it charges. As charging times decrease power output for a battery pack naturally increase.
- You can order your Plaid Model S now (<2 second 0-60) ...btw it's a family sedan.
- Tesla has secured its own lithium source... locally... in the U.S. to be used in it's own Gigafactory(TeraFactory?) using a new process that removes most of the current manufacturing steps. Said lithium source is enough to "electrify" the entire U.S. vehicle fleet should the entire reservoir be purchased and only in that one state. (there will be no lithium shortage.)
- new battery pack design will be structurally integrated into the car increasing overall car strength while decreasing overall gross vehicle weight. While not currently available for your new model Y, it was directly stated that this will be the way all their cars are built as new factories come online and/or it is feasible to retool.
- Plans for the TeraFactory... seriously they built a GigaFactory in 18 months. Only the ignorant are betting against this.

Any one of these talking points would have other vehicle manufactures throwing a media commercial parade... for Tesla just a Wednesday...

Truly a watershed moment when Elon said he never know just how that trailing zero got into the name of the 18650 Panasonic cell. So from now on it is just a '1865 cell'. All those needless zeros, all those years . . . :rolleyes:

That was a disappointment. I'd thought that when my M3 batteries died, I'd be able to replace them with the better battery, but it looks like they won't fit in my M3.
