There are many types of bodies in the automotive industry. We choose to make a tubular frame. This type of body allows us a very good weight to performance ratio. Indeed, triangulation allows us to stiffen the structure while limiting the mass of materials and the construction costs.
To achieve this, we use 25CD4S steel tubes, an isotropic material, which gives us good corrosion resistance, a very high breaking limit, as well as the desired elongation and elastic limit.

The rear wing, like the front wing, helps balance the aerodynamic. Indeed, the goal is to distribute the mass at 55% on the rear wheels and 45% on the front wheels. We decided to do so because the rear wheels are the driving wheels.
In addition to that, the rear wing creates support and a vacuum under the car to ensure better handling. The flat bottom also makes it possible to create a depression, but also to limit turbulence by increasing the trail in a straight line.

The front wing has 3 main objectives. First of all, it balances the aero with the rear wing in order to have a weight distribution of 45% on the front wheels and 55% on the rear wheels (which are the driving wheels).
It also creates support, in order to flatten the car as much as possible on the ground and create a depression, which provides better handling. Finally, it allows, like the side pods, to deflect air from the front wheels to pass it around.

The side pods are shown in yellow near the rear wheels. For the front wheels, the side pods are directly linked to the wing. For the rear wheels, the sides pods are independent parts connected to the shell.
Their aim is, therefore, to flatten the car on the ground but also to deflect the air from the wheels in order to limit speed losses. They also limit the consumption of our car.

Our battery design allows us to power the two electric motors, both connected by an electronic differential. The motors have a nominal power of 30kW. This will allow us to reach 100 km/h in less than 10 seconds.
At the output of the motor shaft, our goal is to have a chain providing the reduction function to bring an adapted speed to the universal joints. They will transmit power to the wheels of our car, and give us greater acceleration.

The ground connection of the car is ensured by contact with the wheels but also by the role of suspensions, brakes, and steering. Several geometrical parameters of these systems, such as the camber and toe-in angles or the Ackermann sketch, affect the cornering and straight-line performance of the car (grip, handling ...).
We opted for double wishbone and push-type suspensions, with fairly stiff shock absorbers to encourage sporty behavior. To ensure good braking, we chose disc brakes with 2 pistons and 2 master cylinders. Steering will be provided by a classic and precise rack and pinion system. Finally, we have chosen to use tires with a diameter of 13 "and a width of 7.2" at the rear and 6.2 "at the front to have a better weight distribution between the front and rear, and to limit the resistance torque in the steering wheel.
