I know about how it works but which is the most efficient, does it make much difference which size engine i get?

Engine displacement is the swept volume of the engine. It shows the area of the cylinder between the top dead center position of the piston and the lowest point to which the piston travels. The formula make is clear:-
Bore x Stroke = Displacement.
In the auto industry the 2 litre engine is considered a classic and the most chosen engine option worldwide. It suits the typical motoring public and is easy on your wallet to run. All current production engines are very efficient and give you many years of carefree motoring. If you want something bigger then the 2.6 - 2.7 V6 units are also very popular. You go into the big league with any engine above 3.5 litres. So it all depends on what you want; if you choose carefully you will not go wrong.

Displacement is the volume of air "displaced" by the pistons during a single engine cycle. In terms of a single cylinder, displacement is the volume of the space traveled by the piston. The two factors that make up engine displacement are bore and stroke.
To calculate the displacement of an engine, first calculate the displacement of a single cylinder. The formula for the volume of a cylinder:
V = hr2

There is no one most efficient engine. It depends on several things. Weight, profile (aerodynamics), even the time of the year. An engine that is efficient in one model may not be efficient in another model. I usually opt for the bigger engine, better weight to horsepower ratio.

Don't be put off by bigger engines I had a BMW 540i with a 4.4 l V8 and could get 30mpg on the motorway at 70 MPH.
most performance cars are highly tuned and as efficient as they can be.
While a 2L diesel in a large 4wd will give horrendous fuel consumption figures and the diesels give out worse emissions than petrol cars , carbon particles that can pass through cabin filters and stick in your lungs causing cancer later on in life!

The internal dimentions of the cylinders with the pistons at the bottom of the stroke added together.

Well basicaly the engine displaces the capacity.
Hope i helped.
