It’s common sense that loading your car up with extra weight will negatively impact its fuel economy – but the message hasn’t got through to all drivers. The top five offenders are tools, wellies and outdoor clothing, sports equipment and golf clubs, pushchairs and baby equipment, and multiple pairs of shoes. According to the RAC, an additional 50kg of weight can reduce your fuel economy by as much as two per cent. Over time, this seemingly small increase could cost you a lot in fuel. Not only that, but continued heavy loads in the rear could leave your suspension overloaded, while additional weight will also increase your car’s braking distance. The advice is clear: only travel with what’s necessary for your journey, and empty your boot of clutter regularly.
