From 2006, the ready to start weight is applied instead of unladen weight. It corresponds to the unladen weight plus the weight of the propellant (water, oil and fuel) as well as the drivers weight. For passenger cars the weight of the driver and the propellants is standardized at 125 kg. In the statistical data for 2006, 125 kg is deducted from motor vehicles with ready to start weight and are distributed to the original groups of unladen weight.
