Aerodynamics is the study of a vehicle's aerodynamics. Aerodynamics represents the vehicle's resistance to air at a given speed. When aerodynamic drag is optimized, the vehicle's energy consumption is reduced. But also, to improve its circulation by taking into account the conditions outside the vehicle.
Aerodynamics has an impact on :
- Vehicleautonomy
- Energy consumption (petrol, electricity, etc.)
- CO2 emissions
Aerodynamics is an important criterion in the design of electric vehicles. Especially when it comes to designing increasingly "clean" vehicles. Aerodynamics account for 20% of energy consumption.
The main factors to be taken into account for better vehicle aerodynamics are - Lift, Thrust, Weight, Drag.
The coefficient used to calculate a vehicle's aerodynamics is :
How do aerodynamic optimization tests work?
In the laboratory, the Volt undergoes dynamic wind tunnel testing. A propeller produces a wind (~222 km/h) in the room, whose effect on the vehicle is determined by a smoke that the engineers also emit. This smoke is used to study the action of the wind on the vehicle, and thus to rework the aerodynamic curves of the bodywork, and finally to maximize air circulation on the vehicle's walls.
Technical solutions to improve vehicle aerodynamics:
Active Spoiler | Aerodynamic Flaps | Active Wheels | Narrow Tires | Lowering the vehicle's trim

Aerodynamics is one of the factors that determine the aesthetics of a vehicle.
