Summary

This project has shown the limits of downsizing approach applied to a small vehicle. For aspects thermal engine is essentially the low rpm torque, which remained below the targets, this need to use a gearbox with shorter gear ratio, but unfavourable effect on consumption. However, the association of this engine with electric hybrid system has helped make the performance acceptable for both occasions heavy loads for takeovers and urban traffic.
