- The Formula One World Championship gathers the best of engineering to produce the safest and the fastest cars in straight lines and corners. The new FIA budget restrictions and the cost of testing push the teams to use numerical simulations for the development of their car, aiming to reproduce the behaviours of the vehicle on different racetracks. Current published models use a rigid body representation of the chassis to describe the motion of the car. This omits the influence of the powertrain, in particular by not fully representing the action of the Motor Generator Unit-Kinetic (MGUK) system acting on braking. The aim of this work is to predict the vehicle dynamics performance of a Formula One car from a powertrain perspective on three circuits of the Formula One Championship race Calendar. The vehicle model developed on GT-Suite and which complies with the FIA 2022 technical regulations, includes the main elements for predicting vehicle dynamics, such as the vehicle body, wheels, tyres, suspensions and anti-roll bars. The model takes its tire forces and tractive torques inputs from an engine-powertrain F1 model, validated for the 2020 regulations. This work will provide a systematic methodology for integrating a power unit model to a Formula One car model, meeting 2022 technical requirements. The approach used in this model can be used for a parametric study to evaluate vehicle dynamics and powertrain performances of an F1 car for future regulations.
