  2. Automotive aerodynamics - Wikipedia

    en.wikipedia.org/wiki/Automotive_aerodynamics

    A boattail can greatly reduce a vehicle's total drag. Boattails create a teardrop shape that will give the vehicle a more streamlined profile, reducing the occurrence of drag inducing flow separation. [17] A kammback is a truncated boattail. It is created as an extension of the rear of the vehicle, moving the rear backward at a slight angle ...

  3. Kammback - Wikipedia

    en.wikipedia.org/wiki/Kammback

    The design paradigm of sloping the tail to reduce drag was carried to an extreme on cars such as the Cunningham C-5R, [14] resulting in an airfoil effect lifting the rear of the car at speed and so running the risk of instability or loss of control. The Kammback decreased the area of the lifting surface while creating a low-pressure zone ...

  4. Spoiler (car) - Wikipedia

    en.wikipedia.org/wiki/Spoiler_(car)

    The goal of many spoilers used in passenger vehicles is to reduce drag and increase fuel efficiency. [4] Passenger vehicles can be equipped with front and rear spoilers. Front spoilers, found beneath the bumper, are mainly used to decrease the air underneath the vehicle to reduce the drag coefficient and lift.

  7. Drag (physics) - Wikipedia

    en.wikipedia.org/wiki/Drag_(physics)

    A body is known as bluff or blunt when the source of drag is dominated by pressure forces, and streamlined if the drag is dominated by viscous forces. For example, road vehicles are bluff bodies. [8] For aircraft, pressure and friction drag are included in the definition of parasitic drag. Parasite drag is often expressed in terms of a ...

    Automakers would need to meet a new test simulating a head-to-hood impact and reduce the risks of serious-to-fatal head injuries in impacts at vehicle speeds of up to 25 mph (40 km/h), which ...

  9. Car suspension - Wikipedia

    en.wikipedia.org/wiki/Car_suspension

    Certain modern vehicles have height adjustable suspension in order to improve aerodynamics and fuel efficiency. Modern formula cars that have exposed wheels and suspension typically use streamlined tubing rather than simple round tubing for their suspension arms to reduce aerodynamic drag. Also typical is the use of rocker-arm, push rod, or ...
