Bugatti Veyron

If you have read How Car Engines Work, you know that if you want to create a 1,000-horsepower engine, it has to be able to burn enough gasoline to generate 1,000 horsepower. That works out to about 1.33 gallons (5 liters) of gasoline per minute.


How much gas is that?
Here's a quick calculation, which you can ignore if you hate math:
1,000 horsepower is equivalent to roughly 2.6 billion joules per hour. A gallon (3.8 liters) of gasoline contains 132 million joules, so a 1,000-hp engine has to be able to burn just over 20 gallons of gasoline per hour.
However, car engines are only about one-quarter efficient -- three quarters of the gasoline's energy escapes as heat rather than as power to the wheels. So the engine actually has to be able to burn at least 80 gallons per hour, or 1.33 gallons (5 liters) per minute.
Let's convert over to metric. Gasoline requires about 14.7 kilograms of air to burn 1 kilogram of gas. Air weighs 1.222 kilograms per cubic meter at sea level. A gallon of gasoline weighs 2.84 kilograms. So the engine has to be able to process 2.84*1.33*14.7 kilograms of air per minute, or roughly 45 cubic meters of air per minute. That's 45,000 liters of air per minute.
If a V-8 engine is turning at 6,000 rpm, it can inhale a total of 24,000 cylinders' full of air per minute. If it needs to inhale 45,000 liters of air per minute, it works out to roughly 2 liters per cylinder-full. That's a 16-liter engine.

Is your car getting good mileage you do the math.....

 

Acura TL is not a sport sedan, it's front wheel driving dressed up Accord. I think G35 is the best car for the money. I was interested in bmw 335i but the cost was too high! Lexus IS350's interior room is just too small and design could be better. G35 suppose to have 268 torque and the 06' bmw M3 is 280, slight difference but when I drive my friend's stock M3 with it feels much much more torque-ier.

Not denying your math here, but isn't a basic element missing - engine speed? If instead of 1,000 hp, a vehicle is geared to only develop 100HP based on its powerband and RPM at highway speed, it should use a lot less gas than one developing 200HP. There's also how much HP is required to run at highway speeds, etc. etc.

That said, excellent info. And I personally couldn't care less that my G runs at 3k on the highway, it means I can pass faster when necessary

 

hahaha, your right the torque steer was a joke imagine how bad it go with the blower on it! Whoever I raced would have a length on me while I'm trying to get my front wheels from spinning! Frustrating!

 

Absolutely NO remorse, love this car every time I get behind the wheel, or just walking up to it, they nailed most every aspect of this car.
I still can't believe so many complaints about mileage. I get aprox 26 MPG on the highway, and could care less about my city figures as this car is just too badda$$ around town
My hwy figures are going 80MPH too

 

It'll fit one pair of skis, likely NOT in a ski bag.

 

City mileage is hard to figure anyway, so much stop and go, waiting at lights, in lines, sitting in traffic, etc. Lot's of 0 MPG going on, no matter what you drive!

 

I love this car, but I do regret one thing... That my partner and I bought one at the same time, so now we don't have an "old" car to go out and get dirty in! Our trip to Death Valley next weekend won't be as much fun without the off-roading experience of the Saturn SL-1 or Honda Accord that we both left for the G35.

 

Just rent a car for the trip, I do!

 

absolutly zero regret!! i actually look forward to driving it everyday... however, having the back seats down would be nice... so that way i can slide the snowboards through the truck instead of having it standing up.

 

Good insight in here

 

Buying this car is without a doubt the best decision I have ever made. I bought an 08' fully loaded and this car is unbeatable. My friend just bought a bmw335i - it doesn't have half the options/features that my car has and he paid 10 grand more!

this is the best looking and best driving vehicle you can get for your dollar.

 

I must say I completely agree... every time I look, drive, or modd the car a smile still comes to my face, I dont think it will ever go away!
