example:- a car weighs 635 kgs with 221 bhp, so
1 tonne divided by 0.635 tonne = 1.574 approx.. so 221 bhp times 1.574 = 347.854 bhp per tonne...
Does anyone know how to work out power to weight. thanks.
quite simply.
you divide the power of your car by the weight:p
as for getting the figures, a weighbridge and a rolling road are about your best options.
have a look at some of the online calculators or data websites if you have a standard engine for the power output.

Take the weight and find the number required to multiply to take it to a tonne.. then multiply the horsepower by the same amount...

Metric Tonne is 1000 Kg
Your car is 600 Kg
Your BHP is 150.
Divide 600 X 150 = 0.25 and multiply by 1000. = 250 BHP per Tonne
the way i work it out is
metric tonne is 1000kg or 1
your car is 600kg or 0.600 of a tonne
your bhp is 150 per tonne
so 150 bhp divided by 0.600 should work out the output of the car
150 / 0.600 = 250 bhp per tonne
hope this help in some way
Maybe its just me but in cars this light , the drivers weight should be included. But that is just me.

If you are trying to compare your cars spec to known production cars then just use the wet weight. ie full of fuel and fluids but no driver.
If you want to know the overall on road figure then use wet weight plus driver.
Most people use wet weight minus driver.
I think many weights quoted are pretty much dry, only incl a few vital fluids.

SVA weight is all fluids, full tank, no driver or passenger.
The standard SVA test does not give you a true vehicle weight (unless you specifically ask for it) It merely weighs individual axles.

surely adding the axle weights will give the wet weight?
