Summary[edit]

Description
Nederlands: Vermogen van auto's van verschillende merken (Ferrari, Porsche, Kadett, Panda in kW) als functie van de topsnelheid.
English: Figure A.13. Powers of cars (Ferrari, Porsche, Kadett, Panda in kW) versus their top speeds (km/h). Both scales are logarithmic. The power increases as the third power of the speed. To go twice as fast requires eight times as much engine power. From Tennekes, Simple science of flight (1997).
