• This front layout has the disadvantage of requiring a relatively large carrier structure length between the center of the front wheel and the front end of the vehicle. This length has the consequence, on the one hand, to increase the overall length of the vehicle and, on the other hand, to increase the front overhang. Too long a length of this overhang front detracts from the "style", the aerodynamics, the mass and the cost of the vehicle, the radius of turning between walls, and reduces the angle of attack, c that is to say the maximum inclination of the ascending slope that can approach the vehicle without damaging the bottom of the body. To overcome one or more of these difficulties, it has already substantially changed the implementation of the aerothermal module, or at least one of the elements that constitute it.
