To correct a few assumptions in the comments:

- In Germany, power is NOT measured at the wheel, but at the engine outlet before the gearbox, using standard fuel; the fan, water pump, cooling air fan, fuel pump, injection pump and unloaded alternator must also be operated. (DIN 70020-6)
- The power that the engine can deliver THERMALLY (theoretically) endlessly applies.
- Until 1972, power was measured in the USA WITHOUT auxiliary units, which is why historical power figures, e.g. from muscle cars, are regularly very high.
- Since 1972, SAE J2723 is applied in the USA, the measurement of which is different but the results are very similar to those of the DIN 70020-6 measurement. Thus: this is not the reason for the differences.
- A car must be marketed with the performance specifications of the country in which it is sold anyway. I.e. a Porsche is offered in the USA with SAE PS specifications.
- Tax in Germany is NOT calculated according to performance. But insurance is (and to a few other factors, in particular the number of years without accidents)
- Most youtube channels and car enthusiasts measure their cars power with dynos. Roller dynamometers are notoriously inaccurate - deviations of 20% from the actual performance are not uncommon (for various reasons) … of course nobody wants to believe it.

And also - guys - the title of the video with "shameless liars" to then reveal that they allegedly deliberately understate performance is of course clickbait. You don't have to take that seriously!
