same car ....different video (http://youtube.com/watch?v=wfFAZ5-P04I&mode=related&search=)

watch the above video.....am i the only one still stoked about this car? i had forgotten about it for a while, just saw another video of it.

how do you get 1001 horse power you ask?

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.

lets convert over to metric now.....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.....thats about 45,000 liters of air per minute.

so 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....which is a 16 liter engine.

but there isa problem: A 16-liter V-8 engine would be very large....and the pistons would be massive, so there would be no way it could turn at 6,000 rotations per minute (rpm)...at best it might turn at 2,000 rpm, meaning that you would need an immense 48-liter engine to generate 1,000 hp...and clearly an engine that big is impossible in a passenger car.

this is where the fun begins....i love turbo chargers :) (a turbo pressurizes the air coming into the cylinder so the cylinder can hold more air).....(so if you stuff twice as much air in each cylinder, you can burn twice as much gasoline. even though it's not quite a perfect ratio like that....you get the idea)

the veyron uses a maximum turbo boost of 18 PSI to double the output power of its engine...which allows the engine to downsize from a 16 liter to a 8 liter engine

what tripps me out the most about this engine is how its put together. they needed an engine that was able to keep the RPM redline high and to lower lag time when you press the accelerator.... in doing this they double the number of cylinders. the bugatti has a very rare 16-cylinder engine if you were to look at it, its 2 V-8's connected together that share the same crankshaft. both V-8's both contain twin turbo's. :) a V-16 quad-turbocharged...... i have fantisies about this idea. if you were to really look into the detail, instead of seeing a v form from the pistons, you see a W.... :) so, just replace the v-16 from above and call it a w-16 engine now :)

this W-16 engine is amazing. the engine has four valves per cylinder, for a total of 64 valves...it has a dry sump lubrication system borrowed from f-1 race cars, along with an intricate internal oil path to ensure proper lubrication and cooling within the 16 cylinders....it has electronically controlled, continuously variable cam timing to create optimal performance at different engine rpm settingsand it also has a massive radiator to deal with all of the waste heat that burning 1.33 gallons of gasoline per minute can generate.

and this engine..suprisingly is rather compact...it measures just 710 mm long, 889 mm wide and 730 mm high.

the transmission is unique, in particular because it has to harness about twice as much torque as any previous sportscar transmission, it has 7 gears, a dual clutch system, sequential shifting, and has paddle-driven computer controlled shifting system.


this computer-controlled system is identical to the sort of system found in a f1 car ....there is no clutch pedal or shift lever for the driver to operate, the computer controls the clutch disks as well as the actual shifting....the computer is able to shift gears in 0.2 seconds.

it would be almost impossible for all of the torque available from the W-16 engine to flow out to just two wheels without constant wheel-spin., therefore, the veyron has full-time all-wheel drive :) by applying the engines power to all four wheels through a computer controlled traction control system, the car is able to harness all of the engines horsepower...even at full acceleration. :evil:


so much more to talk about..... this car excited me. alot of detail also went into the body work( aerodynamics on keeping the car on the road at 253 mph), interior, finding the right tires.....ahhh, i like this car...anyone wanna spare me 1.2 mil :)

I didn't see any room to put a carseat.

You should of asked to see it when you were here DU, it was parked in the garage.

[Emerson1]

No, you saw the above ground garage.
