The present invention relates to a method for improving startability of a vehicle, said vehicle being provided with a prime mover (2) and a kinetic energy recuperation system (12). The prime mover (2) is adapted to propel the vehicle either alone or in combination with the kinetic energy recuperation system (12) which is operably coupled to the prime mover (2) and to wheels of the vehicle and is adapted to store energy at times when there is an abundance of energy and to use energy at times when there is a demand for energy. The present invention also relates to such a vehicle. The method comprises the steps of determining that the vehicle is standing still or essentially standing still (101 ); detecting a take-off assistance condition (102); detecting a level of energy in the kinetic energy recuperation system (12; 103); if the level of energy is found insufficient, connecting the prime mover (2) to the kinetic energy recuperation system (12) and running the prime mover (2) such that energy from the prime mover (2) is stored in the kinetic energy recuperation system (12; 104); and when a driver requests the vehicle to take off, running the prime mover (2) and consuming energy from the kinetic energy recuperation system (12) such that the wheels of the vehicle initiate propelling thereof (105).
