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 ...
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 ...
Hall had attempted several times to make a flying car, but stuck with a more conventional design for this car. The streamlined styling was considered to be modern and quite appealing, and its tiny wheels made the car look larger than it actually was. It used a large amount of aluminum and plastic to reduce its weight.
As the number of electronic control units in a vehicle grows, the amount of connectivity needed also increases. The average vehicle includes several miles of copper wire - weighing up to 150 lbs ...
Persu car (1922–23), designed by Romanian engineer Aurel Persu, who improved on the Tropfenwagen by placing the wheels inside the car body; Burney car (1929-1931), working prototypes designed by Dennis Burney and manufactured by Streamline Cars; Dymaxion (1933–1934), U.S. "teardrop" car [44] Stout Scarab (1932–35, 1946), aerodynamic US car
Lowering the drag coefficient comes from streamlining the exterior body of the vehicle. Streamlining the body requires assumptions about the surrounding airspeed and characteristic use of the vehicle. Cars that try to reduce drag employ devices such as spoilers, wings, diffusers, and fins to reduce drag and increase speed in one direction. [4]
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 ...
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.
