GVM = gross vehicle mass, usually calculated when the car has a full stock of fluids including petrol and a driver but no passengers.
Tare Weight = in car terms, is the amount of weight it is rated to carry, basically the number of average passengers and total cargo over and above the GVM (tare = gross - net).
Kerb Weight = calculated by the maufacturer of the car and is the car's sprung weight (ie: sitting on the road on its wheels, not weighed on a a chassis scale) which includes full fluids (incl. petrol) but no driver, passengers or luggage.
Hope there is no more confusion

So I should use kerb weight to calculate weight/power ratio.
I'm thinking how EJ8 compares to EH9 (data from red book)
EJ8 is 1029kg/93kw = 11.06 kg/kw
EH9 is 1088kg/96kw = 11.33 kg/kw
EJ8 seems to be faster by a hairline .. I was thinking between those two. I'm glad I chose EJ8... though a sunroof would be better
Check out the IZZ rolla: 1081kg/100kw = 10.81 kg/kw
very close with DC4 (Gsi): 1075kg/101kw = 10.64 kg/kw
You would actually be better off calculating power to weight using GVM since it has the driver on board. Any time your actually moving about, ie: when a power to weight is relevant, there tends to be a driver on board Just a thought.. It's more of a real world calculation...

GVM = kerb + driver's weight
What's the weight of driver used in that calculation? Commo driver's weight will be more than Honda driver's weight... cos Australian is heavier than asian . Assuming same driver drives those car, then kerb weight is more suitable then.
Maybe all drivers is better to follow Jenny Craig program before go for tracking... hehehehehe

funny since ive seen a few more asian people in commodores and white people in Hondas (myself included )
Seriosuly though , id think there is some "average" human weight which is taken into factoring the "GVM" of a car.
