One of the key elements of automotive aerodynamics is the management of airflow around a vehicle.

It was redone five times due to several issues. The loft wasn't done correctly and wasn't saved, the hole in the back was missing, and a circle was used instead of an arch.Problems with conversion properties occurred, with the wrong options selected for the hole and lines.
Many hours were spent repeating steps and troubles, trying to fix the issues and figure out what went wrong, it wasn't possible to set the requested radio (3) or even (2); only one radius was accepted, which is why the final result appears slightly different.

2/7/2025: We raced our cars, and I raced my car next to Sam's. I beat him with a time of 3.19 seconds, and overall, I finished in second place.
I had to make some modifications because, as you can see, my car was moving in a zigzag pattern. The problem is the wheels are hitting the car. My two solutions are adding washers or changing the wheels to thinner ones, but there’s a risk that it might not work or the car could fall to the side.

2/10/2025: Raced against Zack's car and achieved the best time (first place) compared to others in the class, with a time of 2.7 seconds. Made changes to the car, including getting new wheels, cutting the axles, and adding a washer to the fourth wheel.

2/11/2025: I received second place with a time of 2.308. This time, I changed one wheel on my car, and it was aligned. I also sanded all the holes in my car so it can spin better.
