However, the factory settings curb weight designed with reserve to ensure stable operation of all systems. When choosing a package, you should pay attention to the presence of air conditioning, an audio system and other options, as they also add weight to the overall figure.
⚠️ Attention: When calculating payload, always subtract the weight of the driver and passengers from the gross weight to avoid exceeding the permissible limit for the suspension and tires.
Gross weight and permissible load
Gross weight is the maximum permissible weight of the vehicle, including the weight of the vehicle itself. Nissan Sunny FB15, driver, all passengers and cargo in the trunk. For this model, this parameter is usually about 1580–1650 kg, depending on the sales market and specific engine modifications. Exceeding this value is strictly prohibited, as this leads to accelerated wear of parts and reduced safety.
When planning long trips with your family or transporting large loads, you need to calculate the total weight in advance. For example, if there are four passengers in a car weighing 80 kg each, and there is 100 kg of cargo in the trunk, then the total weight will be the sum of the curb weight and these additional kilograms. The remaining difference to the total mass is your reserve, which is better not to exceed.
Rear suspension design FB15 designed for certain loads, and regular overload can lead to sagging springs or damage to shock absorbers.
