aerodynamics plays a very important role in the vehicles, not only to better penetrate the air and as well fuel saving and will also achieve better performance in a straight line, but, in addition, make a car more stable in the step for the curve and avoid take off from the ground at high speeds and in a hump, for example. The cars, especially in competition, are designed to get a large balance between aerodynamic support and the least resistance to the air as possible.
In the decade of the 70 in the Formula 1 began to speak of the ground effect. Was to make a few designs on the underside of the car were completely flat and the rear of the car was slightly more elevated than the front. This means that, when you go so close to the asphalt and high speeds, the air is channeled by the low when it comes to the rear of the car generates a suction, suction which gives a higher grip to the vehicle. Just the reverse of the wings of a plane.
This method will employment for the first time in Formula 1 team Lotus. The Brabham BT48b sought a solution similar to to get to be as fast as the Lotus in the cornering, but far more eye-catching to the eye. Installed a powerful fan in the rear of the car, on the diffuser. With this it is achieved that the air flowing at an increased speed below the vehicle, which led to even more grip and a greater ground effect. Little lasted them the invention, since a few races after it was banned by the FIA. Now, the prototype Ariel Atom Aero-P uses a design similar to clearly inspired by the Brabham.
This concept has two powerful electric fans in their low that are activated when it is necessary a high thrust aero (known as Down-Force), that is, on curves and in braking. Instead of resorting to tweaks and ways that would criminalize the always minimalist image of the models of Ariel, the car generates the ground effect in this way. What is most curious is that the designers are working on to find that suction even in a stationary, to allow a acceleration from 0 faster, because it would prevent in part the tendency to drift in the first few meters in the acceleration from a standing start.
Would be very difficult to see something as well marketed in the market. In fact, Ariel has any intention of doing so. Just want to study it and develop it in order to, subsequently, apply it to other functions as the cooling of the engine or batteries in electric vehicles.
