Performance and a full tank of fuel
A full tank of fuel weighs a fair bit so that got me thinking.....is the 0-62 times quoted by manufacturers based on a car with a full tank? Or is this a grey area where manufacturers put in just enough so as to save weight?

a full tank of fuel is 37.5 kilos
It's why an Elise with a full tank of fuel plus a passenger has such an effect on performance
I was following an Elise at Keevil during the early part of the day when I guess it had a full tank plus a passenger and it was significantly slower.....with a car as light as an Elise any increase in fuel or a passenger will have a proportionately greater effect than with a heavier car such as the S2000

Nobody knows how they do the 0 - 62 tests. The results are always within a range and you don't know whether they got the lightest test driver and just enough fuel to get them to 62 or not.
The kerb weights quoted do make allowance for a driver - there's some EEC standard which must make an assumption on the driver's weight. You see so many different kerb weights quoted the only reliable way to found out what your car weighs is to take it down to your local authority weighbridge and pay your Fiver.
In order to weigh fuel a litre of petrol weighs 0.72 of a kilogramme ( a litre of water weighs 1 kilo and petrol is 0.72 of the equivalent amount of water.
