Do some cae makers still add 75 kg to the kerb wieght of a motor? I think Vauxhall did, can't find specs now.

Have new van (as earlier post) checking weights. Weigh bridge has car at 1800kg if I add 75 kg pretty healthy kerb weighy that.

No long explanations please, Car is master of the fully loaded new van.

If you have weighed the car empty then you can add 75kg if you are looking at the towing ratio. The published kerb weights are often not specific to your car, but may cover a number of variations so may not be that accurate.

That was why I checked dealer had kerb weight at just above 1600gk knew that was not right.

There's different definitions of unladen weight - some include full fuel tank but no driver, others include driver and 90% fuel.

If the 75 kg makes a difference, I guess you're close to the 100% Towing Ratio.

Don’t get concerned now that you’ve weighed the car. Adding 75 kg isn’t going to make one jot of difference to the reality. As said above the spec of the car isn’t always defined where kerbweight is quoted, and different definitions can be used by car makers.

Kerbweight, by legal definition, doesn't include the driver so there's no need to take any 75kg into account.
Mass in service/mass in running order includes 75kg for the driver and sundry items, but kerbweight doesn't.

Nowadays I don't bother really about kerb weights as they don't show a a true tow weight. My car will never be at kerb weight with all the stuff I carry as normal. Ie. Tow rope. grip mats, first aid kit, fire extinguisher, jump leads, tyre pump, probably another ,20 kg. Then when towing all the basic stuff. Probably another 25 kg.

Whether or how you calculate weight ratio is up to you. There's no fixed rule (at least not in the UK), but sources making a weight ratio recommendation base it on a worst case scenario of the car in its lightest possible condition coupled to a trailer in its heaviest possible state. Any other method of calculating the weight ratio would not provide comparable results with other outfits and one might as well forget it altogether.
