1000 HP Electric Cars

This is one of the craziest things I have ever seen. A 1000 horespower super car. With the way it would be torked out (like an RC car) this thing probably hits a hundred in 4 seconds.
"Consider these fun facts: 110 volts times 20 amps (typical household
current) equals 2,200 watts -– that's about the draw of two good hair
dryers. In 10 minutes, that equals 0.36 kilowatt-hours. Now let's look
at the SSC: It's a super-slick, tube-frame sports car weighing 2,950
pounds. It would also have to be shod with foot-wide high-performance
tires to accommodate its purported 208-mph top speed. So add 5% for
frictional drag. It has a coefficient of aero drag of 0.348, which is
to say, it's not very slippery. It has two 375 kW three-phase AC
induction motors for a total output of more than 1,000 horsepower.
Tally it all up and you're talking about a car that would require at least 250 watt-hours per mile, estimates electric car guru Tom Gage, whose company, AC Propulsion, supplies core technology to Tesla, BMW and
others in the field. In other words, to go 200 miles on a charge, the
car would require a 50-kWh battery pack. In itself, that's plausible;
after all, the Tesla pack is 56 kWh. What's wildly, insanely not
plausible, and is in fact a monstrous load of fertilizer, is the claim
that you could recharge such a battery in 10 minutes on household
current. For that you would need to plug into 300 kilowatts, or 0.3
megawatt, roughly the equivalent of a small neighborhood substation."
