Yes. But the real deal is how many liters your engine is. The more liters the more power, but the more gas is used.

Absolutely not. As technology advances and computers monitor and control more and more of the functions of the engine, the engine becomes more efficient, and can produce more horsepower from the same or less fuel. Horsepower is not only related to the amount of fuel burned, it is a combination of many variables. To all those who think this is a stupid question, you are all jackholes.

Not necessarily. The energy required to move your car around is not directly dependent on how big the engine. Cars with bigger engines tend to be heavier and larger though, which means they tend to need more fuel.
If two otherwise identical cars with different maximum horsepower are driven the same speed, the useful work done (after drivetrain losses) will be the same. However, if you give in to temptation and drive the more powerful car more quickly, then you'll use more fuel.

Usually. A lot depends on the vehicle, the engine, the horsepower, driving practices, etc.

i dont think horsepower has anything to do with increasing your MPG. If anything, it lowers your mpg with the more horsepower you have... but im not sure.. heh

more HP means more dead weight normaly , . evenunder idling conditions more mass is to be driven.
actual working conditions do determine MPG. If 200 HP engine is hauling 1 ton of 10 tones of load .
Each engine has its own effciency curve wrt load and RPM.
On fiirst flush increase in dead wt does decrease MPG

No, more efficiency means more mpg, sometimes they work together, but after a point, you are making more power by far than you need and you start to become wastefull again.

no. it will increse fuel usage as will adding power options. the harder the engine has to work the more fuel is required. dont beleive all the car adds about mileage. they will say anything to sell you a car. the more cylinders the more fuel.

Most likely. Now with oil at $96 a barrell. This is not good.
