Because Europe measures horsepower differently than we do.

There are DIN HP and SAE HP.

1 DIN HP = 0.9860 SAE HP.

They are also standardized to slightly different temperatures
and pressures.

In short, 511 PS (or DIN HP) = 505 SAE HP.

Well, in reality, 505 SAE = 512+ PS, but with the different
conditions, it's 511 ;)

An AMERICAN HP is bigger than a European HP :usa:

Brake horsepower (bhp) Brake horsepower was a term commonly used before the 1970s in the (North American republic containing 50 states - 48 conterminous states in North America plus Alaska in northwest North America and the Hawaiian Islands in the Pacific Ocean; achieved independence in 1776) United States, and is still common in the (A monarchy in northwestern Europe occupying most of the British Isles; divided into England and Scotland and Wales and Northern Ireland) United Kingdom. It indicates the brake, the device for measuring the true power of the engine. Stating power in 'bhp' gives some indication this is a true reading, rather than a calculated or predicted one. However, several manufacturers started to strip their engines of essential ancillaries for the purposes of getting a high horsepower figure to use in marketing the car.

hp (SAE)In the United States the term fell into disuse after the American Society of Automotive Engineers (SAE) recommended manufacturers use "hp (SAE)" to indicate the power of the engine, given that particular car's complete engine installation. This may also be stated as "SAE net hp" or simply "net hp". The British market seemed not to need the correction.

Because BHP (brake horsepower) is a different unit than SAE HP. Essentially 511 BHP = 505 HP.
These guys shouldn't worry or forget that the first 25 or more Z engines hot tested came up north of 500HP, most were between 515 and 527 BHP. So I wouldn't be worried after all, SAE has no fear in labeling (proving) the car to have at least 505 BHP.
