Tesla roadster: 8.8 1/4 from the factory.

K1 speed is a go cart track here in So. Cal. Its indoors on a high traction tarmac and they use electric carts. Those are so quick that your back hurts after a few laps. Ive seen the Formula E international race, and its sleepy time boring when there is NO SOUND! They sound like huge slot cars zipping down the track., Just the buzz of the transmissions. And they got a battery change mid race. Electrics just dont tickle it yet.
