~ much more torque than can practically be delivered between the tires and the ground, which is why using a vacuum to improve the traction and eliminate the transient squatting motion of the vehicle is so important in a short race.

Drag racers have had this problem for a long time; those races last less than 5 seconds. This hill climb is interesting because it's only a bit longer, half a minute, which really changes the equations for electric race cars vs. something like Pikes Peak which is 8 minutes to the top (and is now also totally dominated by electric cars).
