Such beauty in an Earthly object is surely a sin.
I don't mind the PGO Speedster...I saw a few at the Paris show this year.bone said:

qube said:US use Net Horsepower which is the power to the wheels and about 75% of the Euro BHP.
This is why the HP figures for US sportscars often look low in comparison to their Euro rivals.

Though with more powerful engines the difference between the SAE and the DIN standard becomes bigger. Since it isn't neccesary to drive the auxiliary equipement not required to operate the engine, with the SAE standard. But it’s mandatory to do the measurements with the whole engine including all extra equipment with the DIN standard.Dr. Woo said:No, no no no...PS is short for Pferdest?rke (quite literally "horsepower"), which is a different method of measuring engine power, though ends up with very similar results to the SAE measure of engine power.
Japanese don't use DIN, certainly not in Japan, since it's a German standard. They use JIS, although the methods of this Japanese standard are almost exactly the same as for the DIN standard.LoudPipe said:British BHP and US hp are SAE based units, SAE net to be exact, and as such they are the same. European & Japanese use DIN hp (or ps) so they, again are the same.
I think you got mixed up, because SAE numbers are always lower than DIN numbers. I think this small difference is why the new M5 will have 507hp DIN: so it can be advertised as 500hp SAE in America. As a comparison, the Mercedes S600 is 500hp DIN/493hp SAE.Wutputt said:Though with more powerful engines the difference between the SAE and the DIN standard becomes bigger.

Idd I got mixed up, with the current SAE standard, the measurement is done with all auxiliary equipment mounted on the engine, so the same as with the DIN standard. The only diference is the fact the conditions between the SAE and DIN standard are different, so the DIN ratings give a bit higher power outputs as the SAE ones (about 1,4% which complies with your examples).chaos386 said:I think you got mixed up, because SAE numbers are always lower than DIN numbers.
