The New IndyCar Makes 250 Pounds of Downforce Going Sideways

The 2018 IndyCar aero kit looks great, and it packs some seriously advanced aero technology.

Back in July, IndyCar revealed its 2018 car design, and it looks amazing. Sure, it might be the same Dallara DW12 chassis underneath, but the new bodykit is a huge step up from the previous look. Now, thanks to this video from IndyCar, we get to see how that new design cuts through the air.

In order to get us a little more acquainted with the 2018 design, put together a quick video with engineer Jon Beekhuis explaining some of the new aerodynamic additions to the body.

In addition to going in a straight line, IndyCars also need to turn. So engineers have to worry about what happens to downforce once the car starts to rotate. In order to mitigate that loss of downforce as the car gets sideways, they've added two pieces: a vertical wicker that runs along the center of the car, and a lateral dome that runs along the bottom of either side of the body.

These pieces together equate to about 250 pounds of downforce if the car is traveling 90 degrees sideways. Of course, that's not how the car is meant to go around the track, but in a corner, at least some of this effect kicks in, giving the car more downward pressure.

Watch for yourself to see just what those pieces look like, and how they help next year's IndyCar take corners.
