In 1973 a small group of engineers entered a 1959 Opel P1 in a mpg contest.

Shell Opel

The contest required a minimum of 30 mph speed.
They achieved 376 miles per gallon in their record run.
They eliminated the radiator and super insulated the engine. A tiny Tillotson lawnmower carburetor with a 3/4” bore was used. It used a direct drive chain from the clutch to a live axle. No suspension. The rear wheels were pushed closely together. It was stripped, chopped and lowered.


I know about that Opel, and they allowed hypemiling as well.

It was just a little game with Shell engineers amount themselves.

And like my testing and on the Bonneville Flats the testing is done with a flying run.
