See real airflow around a reference car — free, with every feature included. No account, no subscription, no in-app purchase FlatSixDynamics is a wind tunnel you can hold. The air around the silhouette of a rear-engined sports car moves live, frame by frame, right on your device. Change the setup, and watch the air answer. No footage. No fakery. Actual physics. You set it. You see the result. Drop the ride height from stock to track, and watch the floor start to work: the air under the car speeds up, pressure falls, and the body is pulled toward the road. Deploy the rear wing, and watch the wake behind the car close. Push the speed slider from a standstill to four hundred kilometers per hour, and watch the spoiler rise on its own, exactly as it does on the real vehicle. Every setup change comes back as a number. Track stance at two hundred kilometers per hour: watch the drag figure settle against stock, while the downforce reading breathes with the wake behind the car. Not your car's certified figures. But a number you can argue with.

Verdict
