Aerodynamic drag is the pesky invisible force that slaps against your vehicle as it hurtles through the air, trying its best to slow you down. Simply put, it’s the air resistance opposing the forward motion, caused by the shape, size, and speed of the object. The more sleek and streamlined your ride, the less drag it faces, which means better fuel efficiency and higher top speeds. It's measured in Newtons (N), and the key players here are drag coefficient (Cd), frontal area, and air density. Reducing drag is why sports cars look like they’re perpetually mid-race and why your average hatchback isn’t.
For the pedants, check your vehicle's manual or engineering specs to see the exact drag coefficient figures.
