Cars with hybrid powertrain substantially reduce the fuel consumption and the environmental pollution, especially at medium and low speeds, because they uses mostly electrical propulsion. The paper presents the mathematical calculation for working regimes of a car with parallel hybrid powertrain system, mathematical model which permits calculation of the propulsion power and torque, as well as the power and mechanical couple at the electrical generator. Dynamics performances for a car with a parallel hybrid powertrain system are presented and compared with the dynamics performances of the same car equipped only with same gasoline internal combustion engine and without hybrid system. From the point of view of performances, hybrid-powered cars can achieve higher accelerations and traction forces than classic cars during autonomy of electric system, due to the propulsion with this system.
