BHP (DIN) is not the same as PS. I have explained all this in another thread.
The 172 has 172 BHP (DIN) and therefore it is 172 BHP. End of story!

To clear up this whole DIN, BHP, PS, KW thing.
172 BHP (DIN) is what Renault quote. DIN is the BHP standard in Germany. Power figures are governed by PS, DIN and SAE to name a few which are all from different countrys (Japan, Germany and America). Each of these are standards to calculate power.
The power figures from each only differ because some counties refuse to use metric, and others refuse to use imperial mesurements.
Consider this: SAE say that a horse (1 BHP) has the ability to move 33,000 lbs of weight a distance of 1 foot every minute. As we all know, exact imperial to metric calculations are a pain, so DIN say that their horse can move a weight of 450,000 kgs a distance of 1cm every minute, which is roughly the same.
It works out that a SAE horsepower is 98.629% of a DIN horsepower.
Im sure that DIN is used throughout Europe since we are all using metric. A cars horsepower claims will nearly always reference the system in place for that country (or region). I think that when Japan state bhp instead of PS, they are stating DIN.
I hope this has cleared up any queries.
