The 1.6 put in the ST was made to be put in much bigger cars. It was most prominent in the Escape in the US.
Ford reduced the displacement to 1.5 to meet China's requirements, but they just tuned it to make the same power.
The FiST only came with the 1.6. If you bought one in China, you paid extra for it.
Of course, people who bought these cars new, knew what they were getting into.
These days, most cars are about having all the accoutrements. Most people see cars as conveyances. They don't see them as "fun."
I'm old. I remember fun cars.
