New Video of Tesla's Mass-Market Electric Car
Slatterz writes "The Tesla Roadster has almost mythical status among electric car enthusiasts. It's fast, with high torque over a wide RPM range, and can beat a Ferrari in terms of acceleration. Now Tesla has released new video of its upcoming new electric car, called the Model S, which Tesla Motors claims is the world's first mass produced fully-electric vehicle. Unlike the Lotus-Elise based Roadster, the Model S is a traditional sedan of the type millions of commuters might actually drive. Tesla claims it will fit seven people (if two of them are 'children under 10'), and has mounted a rather large 17in LCD in the dash. Key to Telsa's future will be the evolution of lithium-ion battery technology. Tesla Motors claiming the new Model S can travel up to 300 miles on a single charge, but the battery will still take 45 minutes to quick-recharge." (And for those in countries where it matters, this article mentions that it should also be available in right-hand drive.)
At $50,000 do they think it is too expensive to call it the model T? Do they think calling it the model T would be too arrogant? Maybe the next one will be cheaper and then they will go ahead and give it the next name. After all we would all like to see the model T version of the electric car that will get us off of expensive oil.
Instead of wasting energy making it accelerate unnecessarily quickly, how about giving it a usefully long range
Why would you assume they can trade battery life for low end torque? One property of electrical engines is they allow for faster acceleration on the low end. It's not like they can somehow get rid of this acceleration while still having an electrical motor with the same top speed and I don't see how they can get more battery life out of the same either.

This is electric, not gas. That isn't a tradeoff. Any electric motor capable of acceptable performance at highway speeds will accelerate very well: it's the way electric motors are. If you put in a feeble motor barely able to go 65mph on the level you would only gain a little range, and nobody would buy it. And it could still lay rubber.

So the Tesla Roadster actually has better acceleration than the Rapide, and considering Wikipedia quotes the Rapide at $240k USD compared to the $110~120k USD for the 2009 Roadster, I'd say the roadster wins on bang for buck there. The Model S in tfa is set to cost ~$49k USD and is still one helluva luxury car. And more than just the initial price, the Model S (supposedly according to Tesla marketing anyway) will cost only $4 dollars to fully recharge from empty.
I could probably rant all day, but the point is, the offerings from Tesla Motors puts an electric car with performance as high as the gas equivalent in the price range of mere mortals and doesn't require you to be an Apple stock millionaire or sell your ocean front property just to buy the damned car...
STOP THAT NONSENSE! Lithium is CHEAP. You can extract it from the saltwater for $50-70 per kg. if all else fails, but right now it's just easier to buy it for $20 per kg. in Bolivia.
Lithium so far is SO CHEAP that it makes no sense to make geological surveys specially for it.
Also, it's almost perfectly recyclable.
Top Gear is full of it. I own a Tesla Roadster and regularly get 180-200 mile range with ordinary driving, and the car recharges empty to full in 3.5 hours on the fast charger.
Weeks of coding saves hours of planning.
Lithium scarcity is one of those myths that just won't die. It's based on a few misguided notions: 1) that lithium makes up most of a lithium-ion battery (it doesn't); 2) it's its most expensive element in a lithium-ion battery (it isn't); and 3) a gross misunderstanding of how reserve figures work.
In reference to the latter case, everyone needs to get in their heads that reserve figures are based on A) what's been found, at B) the current price, and C) current technology. In reference to lithium, A) people haven't really been looking for it because it's so cheap; B) it's dirt cheap; and C) the tech to produce it cheaper hasn't really been needed so it hasn't been worked on.
Even with current tech, a figure of li-ion EVs could easily be sustained through seawater extraction indefinitely. Isn't that the beginning and end of the issue right there?

Hello? Top Gear is for entertainment not facts. They lied for laughs.
It's important to note where the cash burn came from. Initially Tesla was looking at a car that'd only cost $60k to build; they discovered, through an audit partway through development, that it actually cost over $120k to build. They jacked up the price to $109k and have been optimizing it for a while, and finally have it down to where they make about $10k per Roadster -- not a lot for a car that expensive, but not pocket change either. At the same time, as a company, they're still losing money, as they're pumping a lot into Model S development. But they got the loan because they met the DOE's requirement to have a profitable core business (in this case, the Roadster).

so if you drive a car for 5 hours at 30KW then want to recharge it in 10 minutes that means you need 900KW of power. it also means the wires in the car need to be able to handle 30 times the typical driving load.
if the connector was a 208V connector then that's about 4000 DC amps for ten minutes.
you'll be able to degauss your hard drive while you wait!
