11.5 second electric street car
Check out this video. This little battery car is bad.

More like quick and not so fast.
Very impressive and I would trade my Monte Carlo for one in a heartbeat but you would think it would of picked up some major mph from the mod's. Electrics would have my full respect if they could back up there super quick ET's with some high mph. This Datsun would get murdered on a highway roll race, I wish there was a way for it to kick ass on the top end as well. |

Whats the record at for a street legal car with an internal combustion engine, 8 seconds?

The thing about electric cars is that they get all of their torque at zero RPM. However, the fastest production car I've seen one claim to go is about 125 mph which I believe was made by Tesla Motors. I could be wrong about the top speed though.

It's still just a 1972 Datsun that can go one 1/4 mile on a charge... I'll pass.
Good job though. |

I can't resist, I'm sorry. I see people saying this all the time now. They get all of their torque @ > 0 rpm. Torque at 0 rpm is impossible as it is a rotational force. . . just for future reference.

Get some small electrically powered item, like toy or one of those mini electric fans. Please don't use any sort of power tool. Hold the wheel (or whatever is supposed to rotate) and turn it on. You're going to feel it try and move while you hold it stationary. Torque at 0 rpm from an electric motor. It is even possible for an internal combustion engine to generate torque at 0 rpm. Consider a spark ignition, gasoline direct injection engine, with no starter motor and is sitting at rest. One of the cylinders is near the top of its compression stroke. Fuel is sprayed in and while its still atomized within the combustion chamber, the spark ignites it. This causes the pressure within the cylinder to skyrocket. But nothing moves, because the car is in gear and the inertia of the entire drivetrain and the static friction is enough to prevent it from moving. But, slip it into neutral and all of a sudden, the engine comes to life. For the entire time between when the fuel-air mix ignited until the engine ran, there was both torque and no movement, in a reciprocating piston engine. And no, I didn't pull that scenario out of my imagination (well, not entirely). But automakers are working that as an application for the next generation of direct injection engines, starting without a starter motor.

Hmm, maybe I'm wrong, but isn't torque = (force vector)x(displacement vector)? If there is no movement at the point at which force is applied, that means all of the force vectors have cancelled out to zero and torque can not exist. Am I wrong?

In fact, 'static torque' is far more common in the world than 'dynamic torque' is. Usually, its refered to as a moment (particularly in structural engineering circles) but it is identical in concept to torque. Whether its a beam supporting a load, or a guy trying to get a stuck lug nut off a wheel. Nothing is moving, but there are certainly forces applied at a distance, about an axis. You may be thinking of work or power. They require movement, but torque does not.

As a practical example, if you hold a weight out at arms length you feel gravity pulling it down. Consider that the applied force to your arm. To hold it still, you must exert a force to counter gravity, a reaction force. With what you seem to be proposing is that since the thing you're holding is not moving, it must therefore be weightless, which is absurd and untrue. Force exists without movement, and continues to exist despite equal opposition.

Having spent 4 years of my life learning about electricity in engineering school, one of the tortures of graduation was learning everything that you never wanted to know about electric motors. Suffice it to say that you can wind an electric motor in a fashion to blow away just about any fossil fuel motor in existance today in the 1/4 mile. If you created a car with a battery, a power control system and a motor on each wheel, and the right combination of know how, you would be pushing 300 MPH in the 1/4. The car would be very very light in comparison to any other car since you would have no drivetrain other than cables and a battery only big enough to go 1/4 mile.
Is that a practical every day car? No way! But, don't underestimate electric motors for performance. You can do amazing things with them, as the industrial world already knows.
