how can small engines have more horsepower then bigger enignes

that test is retarded. obviously if you drive a car as fast as it can go it will eat up fuel. if they drove the bimmer as fast as it could go it probably would not even do 10 laps on one tank of gas.

i know, but the test just shows if u drive a small engine all out fuel efficiancy goes down. if u drive a big engine within its limits your fuel consumption goes down, cuz it doesnt have to try.
and yuli your right about the f1 stuff, BUT, with a 18,000 rpm limit....thats MUCH higher than any road vehicle, faster it spins, the more air and fuel it gets in, the more power it makes.
being a 2.4L v8 it uses such light parts in the engine that it can spin that fast and not grenade. there is a lot of technology in those engines you will not find in a street engine for many years, usually F1 creates it, once manufacturers realize that it works great, they adapt it into there engines,
F1 Teams spend hundreds of millions of dollars a year on R&D,if they didnt have engines that could do that, id be wonderin where all the money went went...lol

You cant be serious.....
http://en.wikipedia.org/wiki/Boeing_777#Specifications
Maximum range = 5235 nmi converted to 6024.3mi
assuming maximum range uses ALL FUEL (which is retarded)
Fuel Capacity = 31000 US Gal.
Gives us 0.1943mpg
http://en.wikipedia.org/wiki/Formula_One_car
"Race fuel consumption rate is normally around 75 liters per 100 kilometers traveled (3.1 US mpg - 3.8 UK mpg - 1.3 km/l)"
Throw some grade 4 math into the mix 3.1/0.1943 which makes the F1 car almost 16x more fuel efficient than the boeing 777
Of course this is crude math using wikipedia as a reliable source but it demonstrates how out of the park that statement is.

Airbus says the fuel consumption of the A380 will be 2.9 liters (0.76 gallon) per passenger per 100 kilometers (60 miles), assuming seating for 555 passengers. If you consider the maximum seating can be 850, the consumption per passenger is even less. I could not however find any mention that it is also the greatest air disaster in history that is yet to happen...

Just to add some more cool facts, 1986 was the most powerful year in formula 1, turbo 1.5 liter 4 cyl engines producing upwards of 1500hp (rumored to be more but f1 dynos only went as high as 1500hp) these motors were designed to last only 1 race and then be replaced.

As for the question at hand, the horsepower an engine produces is dependent on a large amount of factors. For instance the amount of air and fuel you introduce to the engine and the way you introduce it will weigh in on how much power it will produce. The way you ignite the combustible vapors and how you expel them from the engine will also have an effect on the vehicles final horsepower rating. Another factor is how much the fuel/air is compressed inside the combustion chamber at the point of ignition. Weight, design, and quality of parts will also have a factor, as well the way a motor behaves closer to the top end of it output potential. Things such as Variable Valve Timing can change the way the air and fuel are introduced into the motor at higher speeds, a vehicle without VVT has issues with intake valves closing prematurely at higher speed. This will not allow sufficient volumes of air and fuel into the system to continue building power, whereas VVT allows the motor to "Take a deeper inhale" at higher Revolutions. Engine performance even gets as specific as air temperature affecting final hp!
these are just a small amount of dependent factors in engine horsepower, i tried to make this as easy to understand without all the technical jargon but may have just made it more confusing - i hope it helps anyways.
Understand that the way you put all these factors together gives you the final product, and not all engines use the same combination or style of each component.

I personally have a turbocharged car. I upgraded the ecu with a aftermarket software so that my car gained 20hp more. I do find that my fuel consumption goes down from 12L/100KM to 11L/100kM. I think some turbo engines are just very well made(Audi, Saab). They can be tuned and get 10-30hp with ease and stay in pretty much the same fuel consumption.
