Electric vehicles tend to be heavier than their petrol or diesel counterparts due to a number of factors. The biggest being the battery – as the weight of a battery required to power a vehicle is great, sometimes making up a quarter of a vehicle’s total weight. Due to the importance of the battery, the bodywork required to protect the battery also adds weight to a vehicle. Thicker, more robust metal framework is put in place to ensure a battery is not damaged – including strong shell around the battery. Due to the increases in weight, components such as suspension tend to be more robust in EVs, again adding to the overall weight.
