I agree, if I switch to MPH, I want to see that displayed when changing transmission settings. I figured out in game, some of us show BHP and some show HP but it’s the exact same so if a friend shares a tune that is BHP I just match mine which says HP. But I think you’re correct, in real life, BHP is different than HP from what I understood.Which brings up one of my biggest annoyances which constantly causes confusion: the displayed power output and weight being console language bound without any option to change this inside the game itself while the units selection option only switches between mph and kmh.
German gets kw/kg, US gets bhp/lbs, UK gets bhp/kg, France ch/kg and so on...
1bhp = 1.038 ch/CV/PS/hp = 0.746
1kg = 2.2 lbs
Why this is so convoluted and can't simply be switched to any type in the tuning sheet is beyond me. Especially since GT6 featured sharing of tuning sheets and even gifting whole cars... A prime example of a really useful feature being dropped from "the most complete Gran Turismo ever" for no apparent reason. Lol, just writing about this gets me anxiously frustrated.
You can google the difference and it’s funny because you’ll find articles stating BHP is at the wheels and HP is at the crank and the next article is the opposite. There is a lot of confusion surrounding this because of that I believe. Car and track might say one thing and another site says the other. I always thought BHP was at the wheels and HP was at the crank. So I went looking because of gt7 tune sharing sheets displaying different names and that’s when I found nobody can seem to agree on which is which. LolThe bolded is absolutely not true.
1bhp = 1hp. The difference between bhp and hp is the difference between a unit and a method. Brake horsepower is horsepower as measured at the crank, named as such for the method of a braking dynamometer - which applies a resisting force (braking) to the output. The units it is measured in are (mechanical) horsepower: hp. That "b" only tells you it's crank, and not anything else like wheel (as measured on a rolling road).
The horsepower unit is defined as 550lbfft/s (though the subscript "f", to mean "equivalent force" to distinguish pounds-force from pounds-mass, is often omitted). All variants of metric horsepower units are defined as 75kgfm/s.
Your equivalency formula ought to read:
1hp = 0.746kW = 1.038PS/cv/ch etc.
1PS (etc) = 0.736kW = 0.986hp
Also 1kg = 2.205lb, if you want to be consistent with three decimal places.
