Aerodynamics In Race Vehicles

Automotive racing has evolved into one from the most preferred and highly-priced types of sports in recent years. People go crazy for their favourite teams and drivers and are normally awestruck by the complex race car designs which touch speeds as much as 370 km/hr! A number of amongst them are curious enough to scratch the surface of this deep world of motorsport engineering where engineers put their heart and souls to come up with such ingenious race car designs and elements which impact and shape it.

Aerodynamics, because the name suggests, deals with the flow of air about the car and its corresponding effects. It truly is the newest and therefore the least understood of all subsystems. Aerodynamics wasn’t even deemed relevant for improving lap instances till the 1960s. But now its effects are becoming thought of to deliver better lap timings.


The driving, braking, and cornering forces are created at the contact patch of your tires within a car which can be very affected by the vertical force acting on the tires in conjunction with getting curtailed by a certain maximum coefficient of friction. As a result, if we could enhance this vertical force, we can improve the traction involving the surface as well as the tires resulting within a obtain of cornering forces. This would allow us to reach higher cornering speeds and that as well devoid of sliding!

Growing the car’s weight would enhance this downward force but that would adversely have an effect on the acceleration of your car. Here’s where the astonishing world of aerodynamics wields its magic. The downforce produced by aerodynamic devices present around the car’s body produces a vertical force named ‘aerodynamic downforce’ which increases the load on the tires without having to add a lot extra weight. Hence aerodynamic downforce leads to superior cornering speeds without the need of getting to pay the weight penalty improving the overall lap timings!


Drag reduction was the primary philosophy behind the conception of aerodynamics and remains one of the major regions of modern world aerodynamics. Drag could be the resistive force faced by the car when in motion as a result of surrounding air.

Friction among the car’s surface plus the air is one of the major causes of drag in race vehicles. Drag is proportional towards the square with the velocity from the car and therefore plays a significant part in slowing it down in particular at high speeds. Thus, the physique of a race car is polished and smoothened for hours before a race as it lowered the drag as a consequence of friction. An additional sort of drag is brought on by the distinction in pressure between the front and rear end with the car on account of its motion. Certain aerodynamic devices are used to reduce them by tackling the distinction in pressure.



Racecar wings are aerodynamic devices that assistance to make downforce by exploiting Physics which helps an airplane liftoff. It produces an exactly opposite effect of an airplane wing within a race car. A distinction in speed on its two sides is designed by a wing which in turn produces a force as demonstrated by the famous Bernoulli’s Principle.


Because the name suggests an undertray is an aerodynamic device that provides a smooth passage for air to flow beneath the car. It not only positively affects the downforce generation but also has one in the best drag to downforce ratio among all aerodynamic devices.


A splitter is definitely an aerodynamic device which is somewhat parallel to the ground and is aimed at maintaining the high-pressure air on top rated from the physique surface, thus developing a net downforce.


A diffuser is often a portion on the underbody which can be shaped to create a location of increasingly larger air volume beneath the rear of your car. This makes it possible for for fast-moving low-pressure air underneath the car to decelerate and expand in the rear of the vehicle. The diffuser helps to accelerate the air underneath the car which reduces its pressure, as a result improving downforce. It could also assist redirect the airflow upward, additional improving the downforce.

The world of race car aerodynamics is quite promising inside the near future since it is growing at a speedy pace with constant improvement in technologies. Computational Fluid Dynamics is allowing for an ever-widening space for research and development to try to lower even the slightest possible lap instances which may well be the key for any podium finish.
