A range is a result of various factors such as driving style, use of comfort features, aerodynamics and road conditions. The most important factor is your driving style: a driving style that includes awareness of your surroundings and planning ahead in good time has a positive effect on the recovery of braking energy and thus increases the distance travelled. You can also reduce the power of comfort features such as air conditioning and heating and, if you need to install any outdoor accessories (e.g. a roof box), choose those that are as aerodynamic as possible.
