That's the answer. What's the question ?

#382Re: Tesla Roadster
#383Bold prediction: if they manage to produce a battery capable of 620 mile range promised, it will essentially be game over for ICE cars. My bet is that next generation of Model S and X will easily be in the 400-500 mile rsnge.
When the battery can be refilled in minutes, it will be game over. Until then...
No. I disagree. When you have 600 miles of range, you're going to charge your car at home 99%+ of the time.
Even when you travel that should be enough for a full day driving, which means you will charge it at a hotel or whatever.
Only in rare occasions will the 30 minute fast-charging "inconvenience" you.
Once most EVs will have 100+ kWh batteries, the "slow charging" argument will die off. This is why I hope the 100 kWh battery becomes standard for 2021+ EVs, which should be cheaper than current 60 kWh batteries by that point.
Although I wouldn't discount most carmakers' laziness and greed for profits to keep the batteries a smaller size for as long as possible, unless Model 3 is refreshed with 100, 120, and 150 kWh battery options by 2021, which will force them to make the change, too.

#384The 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.

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 keeping the wheels on the ground at 250mph?

10,000 NM of torque. That's INSANE. I drive a car with 400NM torque and that thing scares the sh*t out of me when I accelerate. 10,000 NM? Isn't that something along the lines of a tram or a train (I'm not sure, I'm asking you guys). This is CRAZY. I'm getting one for sure.
My car has 1092nm of torque from about 1500rpm and it's mind-boggling... 10,000nm is hard to comprehend and surely more than enough to give the occupants some serious whiplash if not sat properly.

I've never had a private garage, much less a locked one I could rewire. If Tesla wants to go mainstream they need to handle apartment parking.
Here in Norway it's common for apartment buildings that have parking spots to have electric chargers outside and that seems to be working fine.
Your population density is minimal, though.

But why does Tesla need a halo car? They already have the consumers’ attention. Lots of people would buy Teslas today but can’t because Tesla is unable to mass produce the Model 3.
To get featured the list of fastest cars in magazines etc., to go to car shows, to get people into a show room, to get featured on TopGear/The Grand Tour, for kids to talk about at school and so on. All of which boost Tesla's brand (outside the tech echo-chamber, where it is already strong).
> to get featured on TopGear/The Grand Tour
I doubt they'd allow that judging by what happened the last time they were featured.

Paper stats are one thing but show me this beating even something like a GT3 in an actual circuit race, or posting a Nurburgring time worthy of the price tag. I’m sure in another 5 or 10 years they’ll get there but these figures are for headlines not the track.
Are you saying that the numbers aren't true, or that it has other weaknesses that would cause it to lose a race?
Think of it this way, if some server or database came out claiming incredible benchmark numbers you’d say okay now show me some real world workloads. Same here. 0-60 is an artificial benchmark, a circuit time is a real world workload.

Traction control has been banned in F1 since 2008, so this severely limits how quickly they can start from a standstill. The tires themselves certainly have enough grip to handle the acceleration; F1 cars routinely hit several lateral Gs in cornering (though with the help of downforce), well exceeding the ~1.4G required to accelerate to 60 in 1.9s.
