Modern society is becoming more and more dependent on mobility, with light vehicles being the main option adopted, which has caused serious impacts. The volume of vehicles in the transport sector added to that of the automobile sector is responsible for levels of greenhouse gas emissions that are almost equal to those caused by the industry. The consequences can be perceived by public health indicators, mainly with the financial expenses to treat the diseases caused by this pollution. Hybrid electric vehicles come as an intermediate option between the conventional combustion engine vehicle and the electric vehicle, to accelerate the process of reducing emissions and consumption. However, the costs of technology raise the price of hybrid vehicles overconventional ones. Thus, this work proposes to evaluate the reduction of fuel consumption of a conventional vehicle with characteristics of a compact national of 999cc. In order to minimize the changes in the vehicle, the proposal is to perform the hybridization through the parallel hybrid architecture of separate axes, known in the literature by Through-The-Road Parallel, making use of a nine-phase induction machine as the motor of the electric traction system, integrated to the rear axis of the vehicle.This work uses driving cycles adopted by the Brazilian standard and a real urbanriving cycle, measured in one of the main corridors of Belo Horizonte - MG. The conventional vehicle was modeled and simulated in the software ADVISOR, and from this, performance and consumption tests were performed between the real and the simulated vehicle. Taking ownership of the conventional vehicle model, modifications were made to implement the hybrid vehicle model, and with that, to evaluate the gains obtained with reduction in consumption, efficiency and emission of pollutants. Finally, a comparison is made between the vehicles hybridized by the Parallel-TTR architecture, and the Start and Assistance Parallel, Known as Parallel-SA.
