I would be curious to know how a 10HP car pulls a family of 4 around ? The (up to) 40 mpg I can understand, cause it ain't got no dang power 😂
Ten horses, hitched to a wagon, pulled a whole lot of tonnage back in the day.
I have an older Toyota Paseo that makes an excellent little road "skate", and while I'm fairly certain that it has a bit more than ten horsepower, it does get about 40 mpg on a fairly regular basis!
