Original name: ホンダX170

Honda can trace its automotive roots back to 1959 when they developed their first automobile test-mule (engine and body package) called the X 170. It utilized a 360cc, overhead cam, air-cooled, 60 degree, V4 engine fed by two side-draft carburetors mounted between the heads, and front wheel drive.
