In electric cars, isn't it basically the same?
Even if there is not a traditional transmission, there is still a gearbox behind the electric motor. Tires only rotate at ~1000 RPM on the freeway where the electric motor in a Tesla might be at 10k rpm. That 10x reduction still needs to be factored in.

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…
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 R…

From Wikipedia's F1 page [0]: > The 2016 F1 cars have a power-to-weight ratio of 1,400 hp/t (1.05 kW/kg). Theoretically this would allow the car to reach 100 km/h (62 mph) in less than 1 second. However the massive power cannot be converted to motion at low speeds due to traction loss and the usual figure is 2.5 seconds to reach 100 km/h (62 mph) Even adjusting for 60 mph = 2.4s, I don't see how the traction of the T…
Per your links, the minimum permissible weight of an F1 car is 731kg including the driver, but not fuel. For FE it is 800kg. The 2011 Tesla Roadster weighed 1235kg, sans driver. The 2011 Bugatti Veyron 1834kg. The very long range also suggests that this car will weigh considerably more than the old Roadster. Maybe there is an improvement to traction with all that extra weight? Or maybe the weight just helps with keep…
The Tesla roadster specs are insane! No exotic carmaker will be able to match it (taking price as a consideration). (no Ferrari, or Lambo, can get that close. This is Formula 1 acceleration speeds). Plus 620 miles of range, and it is a 4 seater. Expensive as hell, but this is exotic car territory. Base Specs Acceleration 0-60 mph1.9 sec Acceleration 0-100 mph4.2 sec Acceleration 1/4 mile8.8 sec Top SpeedOver 250 mph…

Ah, but do the doors go like this ^(o_o)^ or like this \(o_o)/ not like this

I wonder at what speed you get that range. Those specs are in Bugatti Veyron league, even beating it at acceleration (for 1/8 the price tag), but at full speed, the Veyron empties its full tank in... 12 minutes. I'll let you calculate how many miles that is at 250mph.
Also I wonder how many times you can accelerate like that... maybe only once with full charge?
They can't waste a large portion of battery capacity, because the heat from that much energy getting wasted would blow up the car.

Then again, how many people actually care? I don't think they'll have trouble finding buyers.
All nice and good. We see the EV revolution in front of our eyes. But nobody speaks about the EV infrastructure.
At least for the roadster, it doesnt seem to matter that much. The people who will buy this will do it for the flashy logo and the ridiculous (And dangerous) speed of course.
But the revolution is simply the battery. They claim ~1000km on one charge.
This is impressive and might do something about the missing infratructure.
