Bugatti Interiors

Posted by ankilsanghvi on November 15, 2007

The Veyron seats two in lavish style. The interior is swathed almost completely in leather — the dash, seats, floor and sides are all leather. Only the instruments and a few metal trim pieces interrupt the leather experience.

The car also surrounds its occupants with every sort of electronic nicety, including a remarkable stereo system, navigation system, etc.

Is all of this worth a million bucks? Who knows. But regardless, the Veyron represents a remarkable technological achievement.

The Veyron is also likely to represent the far end of the automotive performance spectrum for some time to come. To create a car much faster will require adding even more weight, and delivering even more power to the wheels. The added weight means diminishing returns in the power-to-weight domain. Additional power means more wheelspin.

Look at a Champ car and consider how radical its appearance is compared to a passenger car. Consider also that a Champ car does not go much faster than the Veyron. The Veyron probably approaches the outer limits of the passenger car envelope, and we are unlikely to see much beyond the Veyron in terms of performance.

This is, in other words, as good as it gets.

Some near comparisns of Bugatti Veyron engine

  • 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.
