The KillaCycle uses about 0.6 kWhr for each run down the track. (That includes the burnout, by the way, plus the trip back to the pits, which the ICE drag bike doesn't run, but is towed.) About 7 cents worth of electricity at local residential rates. An equivalent drag bike uses about $3.77

Interesting point. Also, the cars "draft" one another so the air resistance is quite low as well. It takes only ~0.6 HP to move per ton to propel a train 50 mph. About 5% of the energy that it takes to move a truck or a car at the same speed.
