Battery energy density of new roadster vs Model 3?

[Austindude]

Seems like the energy density per unit weight in the roadster is higher than what will be in the Model 3 or for that matter what is in the 100D? Anyone know any of specs?

It's gonna get better by 2019 for sure

It could be higher energy density. Just upping the upper limit for voltage increases pack energy capacity. It'll hurt longevity, but that doesn't matter for a demo car.

This subject is already closed by folks who live in Elons head.

They said that Elon just spouted off some 2020 numbers that aren't possible yet.

I asked this question no less than 10 times in another thread and no one would answer. I received a lot of replies, but no answers.

2020 roadster - significantly small than the current model 3 but has twice the battery range?

I remember 2 years ago the Model 3 had a tow package available per Elon.

Rumored 130 kWh Model S in light of Roadster announcement

My guess is that the Roadster 2.0 pack will have to be at least 2x the volumetric energy density of the current 100kWh S/X packs. Twice the capacity and in a smaller vehicle. Leads me to believe that Tesla is looking to use a battery technology that is not yet in mass production.

Current guesses in the Roadster forum is that they used a double stack of battery packs. The low bucket seats sort of hides the fact that the floorpan seemed elevated.

One of the advantages of Tesla's staged construction of the Gigifactory, should a new battery technology get past scaling problems to production levels, Tesla can build the new line with the new technology. One possibility is Li-S batteries, another Aluminum-Air.
