Hp and BHP are just measured differently and the difference isn't a lot.
1hp is the equivalent to just under 0.99bhp, but 300hp would then be 296bhp.

I sort of agree🤔
my truck is 620hp and will happily pull a loaded trailer up windy hill👍
now a super car with 700+hp will struggle 😂

so it’s all about big flat torque curves 💪
So any idea what the torque figure is for your 620hp truck mog ?

Oh dear.

For an engine, indicated HP is a calculation of fuel/air burn, engine speed, i.e. A theoretical figure. BHP is what is measured at the dynamometer, or “brake” and will be lower due to internal frictional losses, but is the true figure of what is delivered at the flywheel. Wheel Horsepower is lower again due to power train losses, and is the power applied to the road through the wheels. Clue is in the name. Also not quoted by manufacturers as it doesn’t sound as good As the BHP figure.

1 HP is 1 HP whether it’s HP, IHP, BHP or WHP, the name indicates where it’s measured. The metric equivalent is PS, which is app. 0.986 blah blah HP.

MM, to your point about the 620 BHP truck vs the 700 BHP super car, look at the rpm where peak torque is developed. You could gear the super car engine to generate the same torque at the wheels but the gearing to achieve this would increase losses between the flywheel and road wheel, plus in this day and age the fuel costs might be a crippler. A bit like when Ford, GM and International all brought out competing gas turbine trucks in the sixties. Naff all torque, 100,000+ rpm and huge gear trains that were bigger than the diesel engines they displaced.

About 2800 Nm from 1,000 to 1,500rpm
So for example an Aventador produces 759 BHP and 720 Nm at 8500 rpm. Be a much more pronounced torque curve though, hence the power curve would follow. But theoretically this engine could power your wagon, but would burn a lot more fuel and would probably last until your second or third drop of the day.

But hell I'd love to sit at 8500 rpm with 44t behind up a long drag 😎🤜

She’d scream, for sure. Ever sat on anything with a Detroit under the covers? They didn’t rev that high, but it sounded like it.
Don't think so but it's on the list. Love the sound of them.

Curious where you found this nugget of information.
