Interesting, cause ZX3 and ZX5 ( in euro version ) is also called Focus Hatchback....

Litres make you confused? ok....

Let's see..

1.25 L = 76.27 cubic inches ( around 75 bhp )
1.4 L = 85.43 cubic inches ( around 90 bhp )
1.6 L = 97.63 cubic inches ( around 105-115 hp if it has vvt-i tehnology )
1.8 L = 109.84 cubic inches ( around 120 - 130 bhp )
2.0 L = 122.04 cubic inches ( around 140 - 150 bhp )

Now, remember, this is the European Ford Fiesta, I presume, that this will be engine offer ( at least it has been by now, for Fiesta and Focus )...
The above engines are rather good except 1.4 which is a little lazy on the throttle...They are all inline 4 cyl. which is a good thing, since the consumption is not great...dependable on weight of the car....It goes around
2.64 gallons on 62.13 miles ( 10 litres per 100 kilometres...) Those are facts for 1.4 and 1.6 engines... ( calculation based on my 2001 Ford Focus 1.4 L engine )
