The invention relates to a method for controlling a platoon (10) of vehicles (1, X), wherein the platoon (10) comprises a leading vehicle (1) and at least one following vehicle (X) following the leading vehicle (1), wherein the leading and the following vehicle (1, X) at least to a certain extent are commonly controlled by a platoon control system (500) so as to drive at a common speed, wherein the method comprises the steps of: —transmitting data (200) from each vehicle (1, X) to the control system (500) comprising information on a current maximum engine torque output and a potential maximum torque output of respective vehicle (1, X); —identifying (300) which one of the lead and the at least one following vehicle (1, X) that limits an average speed (Va) of the platoon (10); and —increasing (400) the setting of the maximum engine torque output for the vehicle (1, X) identified to limit the average speed (Va) of the platoon (10).
