Tesla roadster 0-60 in UNDER 2 seconds

This car has...wait for it:
7367 lb-ft of torque. Not a typo.
No V8 or any gas/diesel engine can match those torque figures.
7367 ft. lb and it only runs a high 8.

"Only"
That's not the torque the motor makes, that's the amount of torque to the wheels

Remember, torque is just a measure of force. A gas-powered car could have 7368 ft. lb. of torque at the wheel with the proper gearing; that by itself doesn't make it fast.
Horsepower - or, equivalently, kW - is a measure of a powerplant's ability to deliver force at speed. *that* will dictate how fast the car accelerates once it's going fast enough that the motor can no longer spin the tires. Using the data provided by Tesla and a bit of guesswork, we can have:
Roadster weight w/driver: 4000 lbs [guess]
0-60 mph: 1.9 secs [given from advert]
0-100 mph: 4.2 sec [ditto]
Kinetic Energy @ 60 MPH: 650K watt-seconds
Kinetic Energy @ 100 MPH: 1800K watt-seconds
Power delivered between 60 and 100 MPH: (1800K - 650K) / (4.2-1.9) = 1160 K / 2.3 = 504 kW or 670 HP at the tires.
Seems plausible. I'll be curious to see if they can hit their weight targets with the expanded battery pack, but the math otherwise checks out.
I'm less sure about the 1/4 mile ET quoted. The Roadster's spectacularly quick for a street car, but getting into the 8's is all about the 1/8th, and the quoted figures would be well behind my CobraJet (0-60 in 1.5, 0-100 in 3.2) and that car's "just" running 8.7s. So I bet when all's said and done, the Roadster runs mid/high 9.s. Which would be just fine with me
Meh, it's fast but I'll stick with my muscle cars.
im all for tesla. keep bulling cars, selling then lll snag a used P100D model S and replace my SRT jeep with it.
fast is fast, i suspect the answer is taking hybrid tech and going mclearn with it and using it only for going fast. this is why i see the hybrid mustang coming, and being great.

Are you already in?Remember, torque is just a measure of force. A gas-powered car could have 7368 ft. lb. of torque at the wheel with the proper gearing; that by itself doesn't make it fast.

After all these years, you already know the answer to that question
Haha, well hopefully there aren't any delays and you can give us a review.After all these years, you already know the answer to that question
C “Where’s my 3?”
T “Look! 7000ft lbs of tq!!”
C “But I put 30k down on a 3 already”
T “0-60 in 1.9!”
C “My 3 was supposed to go 600 miles”
T “8.8 in the 1/4.....”
C “where is my 3 though?”
T “give us 100k to reserve now!”
C “ I’d love to see the 3 I ordered before you guys make this”
T “ WE ARE THE FUTURE! GIVE US MONEY PEASANT!”

It looks like they opened production to the regular reservation holders (over the employee and family orders), which could potentially point to them getting over some of the teething issues.
Could you even put down $30k on one? I thought it was only $1k.
Musk is now saying that the car might be able to fly "short hops" with rocket technology and that it was only a matter of safety. The sad part is he doesnt seem to be joking.

Wtf.
That seems stupid if you ask me. Like if there was a downed tree in front of you, you would just jump over it?
