haha I am not very good at this. What does 1.8 litre mean? That it can hold 1.8 litres? That doesn't make sense I guess. 
What is CC then? 

 Hold on let me check this out. :p 
Like the Toyota Vitz? How many litre is that? 
BTW the average car here is 800cc. 
edit:
According to the manual it is a 2.5 litre engine, which is pretty small I guess, but not here. My dad's car is 4.8 but petrol is almost free there. 
Oh and this car in the USA is basically the Asian cousin of the Nissan Sentra.
