At Reynolds numbers under 2 million, wings are actually more efficient with more chord, not less. I could have made a high aspect ratio wing the full width of the car, but this would result in a very small chord. That’s a large wing, but because front-wheel drive cars have proportionately less weight on the rear of the car, they don’t need as much rear downforce. ![]() ![]() Most rules limit wings to body width, which on a Veloster N is 71.3″ (181cm). As a rule of thumb, you want the widest wingspan allowed in your racing rules, because this lessens the detrimental effect of wing-tip vortices. There’s a higher lift version called the S1223 RTL, but it really only has an advantage at the steepest angle of attack, and otherwise has less lift.ĭesigning aero for FWD hatchbacks is new to me, and there’s definitely some guesswork involved. This time I opted for a Selig S1223 airfoil. There are a lot of good off the shelf wings, but I wanted to make my own (again). It makes downforce, but not enough to counteract a decent splitter. What the wing/spoiler does is straightens out airflow and cancels some of the lift created by the downward-sloping roof. It’s not exactly a spoiler either, because air goes both on top and underneath it. ![]() The OEM wing on a Veloster N isn’t really a wing, because it doesn’t have an airfoil shape. I wanted a proper wing for my Veloster, that makes enough downforce to match my splitter.
