Automotive aerodynamics differs from aircraft aerodynamics in several ways: The characteristic shape of a road vehicle is much less streamlined compared to an aircraft. The vehicle operates very close to the ground, rather than in free air. The operating speeds are lower (and aerodynamic drag varies as the square of speed).
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
The term drag area derives from aerodynamics, where it is the product of some reference area (such as cross-sectional area, total surface area, or similar) and the drag coefficient. In 2003, Car and Driver magazine adopted this metric as a more intuitive way to compare the aerodynamic efficiency of various automobiles.
Mercedes-Benz also produced several models of RR cars in this period, starting with the 130H (1934). The radical 1930s Tatra format (air-cooled, rear engine and streamlined, teardrop design) was an influence on Ferdinand Porsche's 'People's Car' for Adolf Hitler. As well as being the most produced car ever, it set a trend for RR small cars that ...
Aurel Persu on a 2010 Romanian stamp Aurel Persu automobile. Aurel Persu (26 December 1890 – 5 May 1977) was a Romanian engineer and pioneer car designer, the first to place the wheels inside the body of the car as part of his attempt to reach the perfect aerodynamic shape for automobiles.

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 ...
Aerodynamic rule changes are expected to make Formula One cars one-and-a-half seconds slower per lap in 2019, the governing FIA said on Thursday. Speaking at the Spanish Grand Prix, the ...
