ktrin other words, the engine is quite inefficient... according to that article, other cars are around 1/3 loss. PopSci did a review on the car, and it was proven true from the engineers.

that's proposterous, and completley irrelevant.

THE most efficent piston-based internal combustion engines IN ALL OF EXISTANCE convert about 45% of the TOTAL energy in their fuel to actual motion, and those are DIESEL engines. that's why an average diesel powered car will get more miles to the gallon than an average petrol powered car.

an everage petrol engine converts about a third (33%) of the energy in its fuel to actual motion. its a basic rule of thumb that can be generally applied to almost any and piston based internal combustion engines. petrol or diesel.

stating that the veyron engine is inefficent because is converts two thirds of the energy in its fuel to heat and not to actual motion is exactly the same as stating that ALL piston based internal combustion engines are horribly inefficent. which is true, and science has known that since the honorable karl benz invented his first motorized tricycle...
