Did Tesla say the battery capacity is 200kWh, or is that speculation? If the roadster can get 250 Wh/mi like the Model 3s, it would only need a 150kWh battery to get 600miles range.

Confirmed.
Actually some of us in the US are more familiar with Nm. The bigger issue is the use of wheel torque instead of motor torque. 10000 divided by 10:1 gear ratio divided by 3 motors is 300Nm (221ft pounds) which is pretty docile by tesla standards. I realize the car may need 7:1 ratio to reach 250mph.Why would they list it as 10,000 newton meters of torque? No one knows what a newton meter is or how to relate to it. Use FOOT POUNDS, Tesla!!!
Such a slippery car only needs about 500 kW to reach/maintain 250 mph. Look at McLaren's F1. With better cooling, a 100 kWh Tesla battery ought to be able to do that. Note than Rimac is quoting faster for their 120 kWh C-Two.Tesla isn't doing the 200 kWh pack for the 1.9 second 0-60 dash. They're doing it for the 250 mph top speed.
Are you not aware that 96% of the world population is not living in the US and thus more familiar with sound physics and math standard?Why would they list it as 10,000 newton meters of torque? No one knows what a newton meter is or how to relate to it. Use FOOT POUNDS, Tesla!!!

Yes, it really bummed me out the other day that my Bugatti ran out of gas 15 minutes into my 400 kph cruise.Yes, but to make the gas car smackdown real requires an ability to sustain 400 km/hr for 15-20 minutes (something gasoline supercars cannot do without running their tanks dry), as well as delivering range that exceeds gas cars at normal driving speeds. That can't be done with a 100 kWh pack.

You can't directly compare car weight of Roadster with ICE cars because of its low center of gravity. Lateral weight is bad for handling but vertical weight is actually good. Just think air wings if you don't see it. The weight of battery pack that sits low contributes more to vertical weight than to lateral weight. 4,000lb may not be all that bad not to mention there are plenty of 4.000 lb supercars in the world.

At a realistic 10 kW/min, New Roadster might maintain it for 20 minutes.
Then again, which Tesla ever ran nearly that long at half its peak power? Go drive at 275 kW with your P100D and see how long it lasts. I might be wrong.
I don't think there's any easy way to get the P100D to draw 275 kW continuously. Its top speed is 250 kph, and it takes less than 150 kW to sustain that speed.
Still, there are practical benefits of having a 200 kWh pack - on the Autobahn, and when driving in the less populated areas of North America. Elon reiterated in this week's shareholder meeting that the main reason Tesla is doing the 2020 Roadster is to prove that an electric car can outperform a gas car in *every* category.
I think the 200 kWh pack is more of a PR exercise than something people will actually want. Of course everyone would want the 600 mile or whatever range IF there was no weight penalty associated, but how many people would actually prefer a 300 mile range with 500 kg less battery weight? Especially in a focused sports car like this. I can see why they are doing it to prove a point, but I'm not convinced it's in the best interests of those who are actually buying the car. Until they offer a smaller pack I'm not going to buy one anyway. I don't need a 600 mile range in a car like the Roadster and I certainly don't want the weight!
I think I heard / read somewhere that a set of tires would be about $1,200 US. No clue how long they'd last, but these certainly aren't going to be for Touring.Wouldn't like to be the tyre guy on this project - haul a 2+ tonne car to 60 in < 1.9s, then cruise at 250 mph AND last for more than 600 miles before replacement!
I wonder if they'll cost $30,000 a set to replace like the Veyron...
I think they need the bigger battery to get the performance specs. The 600 mile range is a side effect and in some ways it is icing on the cake.

Please don't take this the wrong way, but this is poor use of terminology. Mass is the correct term you need to be using here (not weight) and mass is definitely the enemy when it comes to performance and handling.
