For around 2,4 million euros, you can get one of only 500 planned Bugatti Chiron with 1.500 hp and a top speed of 420 km/h Call your own. The enormous power of the bolide comes with a huge engine 4 turbochargers and 8-liter displacement generated. But what does the term displacement actually mean? Simply put, the displacement indicates the power a car has. That means the larger the compression area, the more power can generated by the engine. Using the Bugatti Chiron as an example, the compression area has 8 liters. Thus, a performance of from 1.500 HP to be generated.

As the cylinder displacement of vehicles for calculating the vehicle tax is used, but in the case of the Bugatti you can go with do not expect any exemption from vehicle tax. According to the currently valid tax formula, per 100 cubic centimeters or part thereof a fee is payable. That is why the “actual” cubic capacity values are always somewhat under the rounded figures of the vehicle. Therefore, for a car with a displacement of 1,7 liters, the vehicle registration document shows 1.711 cubic centimeters rather than 1.689 cubic centimeters. Because only in this way can the vehicle tax for a vehicle with 1,7 liter cubic capacity be calculated accordingly.
Conversion Cubic Inch - Cubic Centimeter
Cubic inches (in³) and cubic centimeters (cc or cm³) are common units of volume. Cubic inch is a unit primarily used in the United States, while cubic centimeter is a metric unit. Our calculator can also convert from cubic inches to cubic centimeters (ccm³) or vice versa. One cubic inch is 16,3871 cubic centimeters.
The cubic capacity calculation in detail:
If you want to really show off at the next meeting with your friends, then it is best to remember the following formula for calculating the compression area.
The formula is: ? x (d / 2) ² xsxz
But what do these abbreviations mean?
- "?" Is the Circle number (3,1416)
- "D" stands for Cylinder diameter or the Bore diameter
- "S" stands for Piston stroke
- "Z" stands for number of cylinders
Here's an example:
Let's go with an engine 12 cylinders each of which measures 90 millimeters and has a bore diameter of 85 millimeters.
This results in the following formula: 3,1416 x (85/2) ² x 90 x 12
Using this formula, a total volume of 6,017 cubic centimeters calculated for the aggregate. This equates to a little more than 6 liter displacement. However, if you're not a math genius, just take one Displacement calculator to help.
Here's another amazing hint:
According to the American service provider WardsAuto, by 2020 a little more than half of all passenger car engines produced (exactly 52%) should only have a cylinder displacement between 1,0 and 1,9 liters feature. Thus there is a trend towards the so-called downsizing increasingly recognizable in order to be able to comply with the ever stricter CO2 requirements.
Where is the information about the cubic capacity of my car listed?
All information on the displacement can be found in the registration certificate part 1 can be read. With older models you will usually find the calculated cylinder displacement in field 8, while for new cars or current registration certificates in Box P.1 is listed.
How does the actual engine capacity affect the vehicle tax to be paid?
Basically for cars the from July 1, 2009 a base value was permitted. This is for gasoline engines 2 euros for every 100 cubic centimeters or part thereof. In the case of diesel engines, this value is even 9,50 Euros. In addition, a CO2-dependent tax amount has to be paid if your car exceeds 120 grams of CO2 per kilometer ejects. If this is the case, there are additional charges per kilometer 2 Euros per gram of CO2 emitted.
Here's an example: A diesel vehicle with a displacement of 2 liters has CO2 emissions of 150 grams, so the base amount would have to be 190 euros and an additional 60 euros in CO2 tax. You can get the road tax even easier with one Vehicle tax calculator determine. And you can find it here!
Why does a gasoline engine have more horsepower than a diesel with the same cylinder capacity?
This question is answered quickly: The performance per liter is namely with one uncharged diesel engine significantly lower than with a gasoline engine, since the diesel engine has to be operated with a considerable excess of air so that its soot emissions are reduced to a permissible value.
Can the displacement be increased later?
Of course, the displacement can be increased, which in combination with further modifications is a significant one performance increase has the consequence. This is because more fuel can be burned in the enlarged combustion chamber due to the higher air volume. This leads to an increase in performance.
What options are there to increase the displacement?
- On the one hand, the cylinders can be bored to the greatest possible oversize. This changes the compression ratio in the entire cylinder.
- In addition, a crankshaft with a larger stroke could be installed so that the injection system can adapt to the increased demand.
Even if an increase in displacement in the course of tuning provides more power, it also brings some risks with it: The expansion of the displacement can lead to higher engine temperatures and a significantly higher load on the drive train and the brake system. In addition, the Exhaust gas values deteriorate, which means a downgrading to a worse pollutant category, the loss of the manufacturer's guarantee or even the closure of the vehicle would be connected.
Of course, that wasn't the end of it!
