If only the winners ran, the interest would be sparse.

Witness the LeMons races, which has an Effluency Index.

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). The award is named after the "Index of Thermal Efficiency", a prize briefly given in LeMons' namesake the 24 Hours of Le Mans to the car that scored the highest based on a complex formula that took into account car weight, fuel usage and average speed. This Weird Panhard Is The King of Le Mans Efficiency

The Mk1 Ford GT40 was introduced to Le Mans in 1964. That’s something you immediately think of as having a low slung and slippery shape, right? That car with its “Le Mans nose” is quoted as having a coefficient of drag in the 0.35 range. What did this little Panhard streamliner achieve? Its coefficient of drag is a Le Mans record of 0.12. That’s absurdly low!

So we’ve established that the CD LM64 is extremely aerodynamically efficient. It was also extremely light weight at just 1230 pounds. Add in a supercharged 848cc flat-twin engine with 78 horsepower and you get a car that can run at 137 MPH at flat chat.

While I realize how incredibly dangerous it would be for such a thing to exist in 2019, I would have loved to have seen a modern streamliner out on track this weekend with a 250cc motorcycle engine revving to 19,000 rpm and a hybrid electric motor and active aero getting 60 miles per gallon or something equally absurd in race trim.
