1 PS = 75 kilopond·metre/second ~= 735.5 newton·m/s ~= 735.5 W ~= 0.7355 kW ~= 0.98632 hp

I got it from here

It's correct. PS, i believe stands for Pferdest rke and is the German for Horse power. Looking at the conversion(.98 against 1), one can assume that the German horses are weaker than European ones.

I guess nowadays companies are sticking to PS since it turns out to be 1-2 more than bhp. Eg. i10 Kappa: 80PS. Psychologically 80 sounds more than 78.x.

BHP is the British system and PS is used as metric system

1 PS = 75 kg x 1 g (9.8065 mts/sec2) x 1 mtr/sec = 735.4875 Watts

1 BHP is about 746 Watts

To avoid confusion, some countries are using SI units for Power (Kilowatt)

Why can't the industry use one standard format accross the board ? Life would be much simpler. I think HP is the most widely understood & accepted term. If all companies stick to that, comparisons would be far simpler !!

Instead of BHP / HP / PS / Kw..etc etc




Cheers

bhp is the real thing (team bhp) while PS(photoshopped) is what you get to make it more pleasing. 78bhp = 90PS. See.
