Rear view of a "rail"-style dragster, with external wheels. The hollow container for the carbon dioxide cartridge can be seen towards the rear of the car. CO 2 dragsters are cars used as miniature racing cars which are propelled by a carbon dioxide cartridge, pierced to start the release of the gas, and which race on a typically 60 feet (18 ...

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.
In theory, the wedge body offered an aerodynamic advantage, decreasing turbulent airflow over the rear wheels, as well as increasing downforce; [3] in practise, the extra weight exceeded any advantage. Miller ran the car for the 1974 season, but had "mixed results"; [1] the car had no obvious edge over more conventional rear-engined dragsters.
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).
Wynns Stormer is a streamliner dragster. [1]Built in 1972 by Woody Gilmore (who also produced Don Prudhomme's wedge digger), on a Woody chassis, [2] the car had bicycle front wheels and dropped front axle, a very pointed nose, and an engine cover with broad, wedge-like fairings over the exhaust pipes, ahead of the rear tires; the fairings sloped steeply from track level to the top of the tires.
Specifications judging Specifications judging is a detailed inspection process where the race car is assessed for compliance with the STEM Racing Technical Regulations. . Scrutineering is conducted within the confines of parc fermé where judges use a series of specially manufactured gauges and accurate measuring tools to check the car's compli
A number of early European automobile manufacturers experimented with the automotive use of aircraft engines, including Hispano-Suiza, Renault, and Rolls-Royce, although it was Fiat that made perhaps the first true aero-engined car when it created the Tipo S76 in 1910. [1]
