That’s right; Subaru’s first car to be introduced in large numbers to the U.S., the 360, was fuel efficient enough to achieve 100 miles per gallon when paired with a specifically-built 3-wheel chassis.
From Subaru of America:
In the early 1970s, a three-wheel, aerodynamically shaped Subaru vehicle achieved 100 miles per gallon. The testing took place in Japan, where the car was driven by a female Japanese racecar driver. Previously located in SOA’s research and development office in California, the car is now stored in the attic.
