A vehicle, system and method for improving driving efficiency for a first host vehicle with at least one propulsion unit and at least one energy storage unit are provided. The method comprises; determining a first set of parameters which affects driving efficiency before a driving session with the first host vehicle is initiated and providing input indicative thereof to a user interface or an autonomous or semi-autonomous driving system of the first host vehicle, monitoring a second set of parameters which affects driving efficiency during the driving session of the first host vehicle, comparing parameters of the first and second set of parameters with corresponding parameters received from at least one second host vehicle, and in response to identified differences between parameters of the first and second host vehicle, and providing input indicative thereof to the user interface or the autonomous or semi-autonomous driving system of the first host vehicle.
