been trying to find out what 1.1, 1.3, 1.4, 1.8 and 2.0 litres on a engine mean.
1, does it mean how much petrol the engine will be burning or how much petrol is in the engine, i just dont have a clue.
2, Whats the difference in the amount of petrol a 2.0 litre Golf burn and a 2.0 litre scooby burn if both driven the same
3, For example would a 2.0 litre scooby with 208BHP burn more petrol than a 2.0 litre Golf with 120BHP (bothe driven the same)

Is it not the displacement, which is effectively the volume of the holes are when the pistons are at the bottom? That's why you can increase displacement with a stroker kit (make the pistons go up and down more) or shorter pistons.
Amount of fuel used will be a function of:
displacement
air/fuel ratio
rpm

These figures are a capacity measurement, it just means that a 1.1 litre engine has a cubic capacity of 1.1 litres. These figures are only a guide as a Scoob is 2 litres but is actually 1998cc (cubic capacity)
Oh and the scoob(cammel) would burn more fuel.

A scooby will use more fuel because its a HIGH performance car, hence..more fuel faster the car.
The golf is not a high performance car so will not use as much petrol.
There is loads of other reasons but i'll leave that up to the techies on here.

mpg is rather complex & depends on a lot more that just the engine. Having a car shape not dissimilar to a dropped brick doesn't help. But the difference between a turbo & non-turbo car is fairly simple, or can be made so. In both situations, assume under load, and correct fueling is used:
non-turbo: 2 litres means 2 litres of air + the fuel to make it go bang correctly
turbo: 2 litres at +1 bar, means 4 litres air crammed into the 2 litre hole, + fuel to make it go bang. So that'll be twice as much fuel.
A bit simple, but sort of does the job!
