The Aero Problem Nissan Solved Between the R32 and R35 GTR

How did Nissan go from a car that generated lift at speed to one that produces downforce — while also reducing drag? In this video, I break down the aerodynamic evolution from the R32 Skyline GT-R to the R35 GT-R using detailed CFD simulations. Rather than guessing, I ran computational fluid dynamics on both cars under the same conditions to understand: Why the R32 generates lift How the R35 controls airflow and produces downforce Where drag is actually being created on each car What 20 years of aerodynamic development really changed The R32 simulation in this video was commissioned by a viewer (Matthew), and it's a great example of how modern CFD can help with car design. 🔍 What’s covered in this analysis Velocity and pressure distributions Underbody and wake behavior Streamlines and drag production Lift vs downforce comparison Drag coefficient comparison All results shown come directly from CFD. 🚗 Want CFD run on your own car?
