A substantial amount of downforce is available by understanding the ground to be part of the aerodynamic system in question, hence the name "ground effect". Starting in the mid-1960s, 'wings' were routinely used in the design of race cars to increase downforce (which is not a type of ground effect). Designers shifted their efforts at ...
This effect is referred to as "aerodynamic grip" and is distinguished from "mechanical grip", which is a function of the car's mass, tires, and suspension. The creation of downforce by passive devices can be achieved only at the cost of increased aerodynamic drag (or friction), and the optimum setup is almost always a compromise between the two.
The Lotus 88 is an innovative Formula One car designed by Colin Chapman, Peter Wright, Tony Rudd and Martin Ogilvie of Lotus in an effort to maximise the downforce produced by ground effect. The Lotus 88 made its debut at the first practice session of the 1981 season opener, the US Grand Prix West at Long Beach.

The FW07 became FW07B in 1980, and Alan Jones, now with Carlos Reutemann, developed the FW07 further, working especially on setup and suspension strengthening.The car was now so efficient in creating downforce from its ground effect design that the front wings were unnecessary.
A ground vehicle has fewer degrees of freedom than an aircraft, and its motion is less affected by aerodynamic forces. Passenger and commercial ground vehicles have very specific design constraints such as their intended purpose, high safety standards (requiring, for example, more 'dead' structural space to act as crumple zones), and certain ...
By raising the nose cone of the car, Postlethwaite and his team increased the volume of air that was able to pass underneath the car. Conversely, the efficiency of the front wing aerofoils are increased the closer they are to the ground. These conflicting requirements led to the design of the 019's distinctive inverted-V, anhedral front profile.
By utilising the integrated aerodynamic fan, the T.50 can suck the air under the car at a 90-degree angle and provide a significant increase in overall downforce as it provides a laminar flow of air passing over the rear diffuser, thus, creating a greater level of suction in tandem with the Venturi effect, created underneath the car, ahead of ...
