It is called the Ka in the UK.
“Environment and sustainability
Each of the engines available is low-carbon, emitting less than 120 g/km CO2. Choose from the responsive and economical 1.2 litre Duratec petrol engine and the advanced 1.3 litre Duratorq TDCi diesel. The Ka is also impressively economical when it comes to making your fuel go far – achieving 67.3 mpg combined.”
They do not produce the Ka in the US. In fact, they don’t even produce the Fiesta in the US. I’d wager that particular car is manufactured in Colone, Germany, but that is just a guess....
The smallest car that they make in the US is the Focus (C-Platform.)
