Yes. Roof racks and roof boxes can reduce a REEV\u2019s electric range and increase petrol consumption when the range extender is supplying energy. They add weight and aerodynamic drag, with the effect generally becoming more noticeable at motorway speeds.<\/p>\n\n\n\n

A roof box can still be useful when the boot is full. You just need to account for the extra energy use and check the vehicle\u2019s load limits before packing.<\/p>\n\n\n\n

Why Does a Roof Box Affect Range?<\/h2>\n\n\n\n

Equipment on the roof changes how air flows around the vehicle. The electric motors must use more energy to overcome that resistance, particularly at higher speeds. Additional weight also increases the energy needed to accelerate and climb hills.<\/p>\n\n\n\n

Research from the US Department of Energy confirms that roof cargo can have a greater efficiency penalty at higher speeds. An empty box still creates drag, so leaving it fitted between trips can affect consumption too.<\/p>\n\n\n\n

In a REEV, this means the battery\u2019s stored energy may cover fewer kilometres. When the range extender generates electricity, the additional demand can also increase petrol use.<\/p>\n\n\n\n
