Tesla Model S uses only 500 watt hours to run a 12 second 1/4 Mile

Drag Times have dyno tested a Tesla Model S Performance to simulate a 12 second 1/4 Mile drag race to answer the question, how many runs will it do on one charge.

The modus operandi is as follows.

Set the regenerative braking to full.

Turn off traction control.

Floor the throttle.

Run the quarter mile and max out at 114 MPH in the quarter,

let off the throttle immediately past finish line.

Let braking regenerate on the rundown.

Going down the strip, it uses 1.1 kWh of power. Regen recoups 0.6 kWh of power, making your power spend 0.5 kWh.

The Model S Performance has an 85 kWh battery, which theoretically means it could make 170 runs before needing a charge. Of course that doesn't account for a 20% discharge capacity buffer or increasing voltage sag as the level of charge decreases. Drag Times says that at current energy costs in Florida, each run would cost just $0.06.

Coincidentally, that is the exact same amount of energy used by the former world's fastest EV drag bike, Killacycle which runs 7.82 @ 168 MPH. The A123 battery powered bike runs 500 hp worth of brushed DC motors and doesn't have brake regen.
