[10] A streamlined motorcycle designed by Charly Perethian with a 185 cc Yamaha motor achieved 372 miles per US gallon (0.632 L/100 km; 447 mpg‑imp) at the 1983 challenge, and is now displayed in the Smithsonian Institution.
Additionally, winners were declared by cost spent on pump gas (or electricity), not strictly mileage, significant as there is a mix of motor types.
Craig Vetter hit a deer while riding his stream-lined Honda Helix on August 14, 2015.
