Abstract[English]
The present invention is directed to a novel vehicle configuration with at least one tunnel (2) enclosed inside the vehicle body, wherein the tunnel (2) comprises an inlet (9), an outlet (10) and a middle section forming a neck (14) of the tunnel (2), wherein the tunnel (2) is narrower at the neck (14) than at the inlet (9) and outlet (10) to achieve Venturi effect The tunnel (2) is applicable to any vehicle type, with all propulsion systems, and especially to electric sports cars. The vehicle configuration with the at least one enclosed tunnel (2) has the following main advantages: reduced drag coefficient, increased downforce, increased vehicle structural rigidity, and better stability of the vehicle travelling at high speeds.[French]
La présente invention concerne une nouvelle configuration de véhicule comportant au moins un tunnel (2) enfermé dans la carrosserie de véhicule, le tunnel (2) comprenant une entrée (9), une sortie (10) et une section centrale formant un col (14) du tunnel (2), le tunnel (2) étant plus étroit au niveau du col (14) qu'au niveau de l'entrée (9) et de la sortie (10) pour obtenir un effet Venturi. Le tunnel (2) peut être appliqué à tout type de véhicule, comportant tous les systèmes de propulsion, et en particulier aux voitures de sport électriques. La configuration de véhicule comportant ledit tunnel (2) enfermé présente les avantages principaux suivants : un coefficient de traînée réduit, une force descendante accrue, une rigidité structurale de véhicule accrue, et une meilleure stabilité du véhicule se déplaçant à des vitesses élevées.
