I was just about to write my own comment about this: the battery capacity is the real eye-opener in this announcement, I think. The new roadster looks like a car which is rather smaller than the Model 3, certainly not larger. And as a sporty car it wouldn't be heavier either.
So how in all worlds do they fit a 200kWh battery in there?
This can only mean, it has more than twice the capacity per weight and volume than the current Tesla battery tech. Very intriguing. Of course, it could be a very obvious case of history repeating itself. The original Tesla roadster pioneered the current Tesla battery tech, what would be more appropriate (and reasonable) than to launch the next generation battery tech with the next gen roadster? The high price and corresponding smaller sales numbers allows for an easy introduction of experimental technology.
You're discounting the fact that this will be released in 2020. We've had a 4x increase in density between 2010-2016.
Also, Model 3 benefits from the new smaller gigafactory-made battery packages (at least a 35% increase in density over older Model S battery packs).
When you take all of this into account, it's very likely that they could fit an older Model S-size battery pack (which is more from 2015-2016 era) in a Roadster 2 with 2x the density.
Oh, I don't doubt, that Tesla can do it :). I just think it is interesting that the specs to the roadster point to a clear and significant increase in battery density. The Model S went from 80 to 100 kWh in 5 years, which is a nice increase but much smaller what they seem to plan with the roadster. And it would be exciting for electrical cars in general, because with that increase a more realistic 100 kWh battery changes from being something you can barely fit into a rather large Model S to something which should fit easily in much smaller cars designed for electric propulsion.
Seeing how Tesla struggles with new car production I would love to see them take a role like Samsung; they can still make popular flagship cars, but they can also become a primary battery supplier to other automakers, just like Samsung has extremely popular flagship smartphones, but also is a primary supplier of parts like OLED screens. I think selling their battery tech could help them become and stay profitable while smoothing over the wrinkles they have in car production.
This could also free up cash flow to give them more resources to work on self driving tech. Honestly, the idea of an electric Honda or Subaru with a "Powered by Tesla" logo could seems really exciting.
