+44% More Downforce? What the Lexus GS350 F Sport Actually Changes

Is the Lexus GS350 F Sport actually more aerodynamic — or does it just look that way? In this video, I run CFD simulations on the standard Lexus GS350 and the F Sport package to see what really changes aerodynamically. This isn’t about styling — it’s about lift, drag, flow separation, and pressure distribution. Using identical simulation conditions, we compare: Velocity, pressure, and streamline behavior Where lift is generated on a sedan How the F Sport package changes flow without creating true downforce Why Lexus focused on stability and lift reduction, not maximum grip The result: a 44% reduction in lift, with only a small drag tradeoff — and a much clearer picture of what the F Sport package is actually doing. 🧪 Want your own car simulated?
