I know what effluence is but had to look this one up!
from the Wiki article:
"Index of Effluency (or IOE) is the top prize awarded in the 24 Hours of LeMons automotive racing series. General criteria to win this award is a car that is too
unreliable to be driven effectively on the streets yet manages to complete a decent number of laps on the race track. IOE can be awarded to a vehicle that was
deemed unreliable from the factory (e.g. Volkswagen Karmann Ghia) or a more reliable car with an unwise engine transplant (e.g. Ford Thunderbird with a
BMW diesel engine)."
