  2. Automobile drag coefficient - Wikipedia

    en.wikipedia.org/wiki/Automobile_drag_coefficient

    Drag is a force that acts parallel to and in the same direction as the airflow. The drag coefficient of an automobile measures the way the automobile passes through the surrounding air. When automobile companies design a new vehicle they take into consideration the automobile drag coefficient in addition to the other performance characteristics ...

  3. Chrysler Airflow - Wikipedia

    en.wikipedia.org/wiki/Chrysler_Airflow

    The Airflow was the first full-size American production car to use streamlining as a basis for building a sleeker automobile, one less susceptible to air resistance. Chrysler made a significant effort at a fundamental change in automotive design with the Chrysler Airflow, but it was ultimately a commercial failure due to a lack of market ...

  4. Drag coefficient - Wikipedia

    en.wikipedia.org/wiki/Drag_coefficient

    Drag coefficients in fluids with Reynolds number approximately 10 4 [1] [2] Shapes are depicted with the same projected frontal area. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.

  5. Mercedes-Benz Bionic - Wikipedia

    en.wikipedia.org/wiki/Mercedes-Benz_Bionic

    Mercedes-Benz reported a drag coefficient of 0.19; [7] for comparison, the production vehicle with the lowest ever C d value was the GM EV1, at 0.195. While the Bionic had a much larger internal volume than the EV1, the Bionic's larger frontal area made the EV1 more aerodynamic overall, as drag is a product of the area and the drag coefficient.

  6. Alfa Romeo BAT - Wikipedia

    en.wikipedia.org/wiki/Alfa_Romeo_BAT

    The lowest of the three cars' drag coefficient was 0.19, [2] an achievement even by today's standards. For each of the cars, Alfa Romeo provided a five-speed gearbox and a powerful four-cylinder engine that produced more than 90 horsepower (67 kW), good enough to propel the car to a top speed of 125 mph (201 km/h). [3]

  7. Porsche Taycan - Wikipedia

    en.wikipedia.org/wiki/Porsche_Taycan

    The Taycan Turbo has a drag coefficient of Cd=0.22, which the manufacturer claims is the lowest of any current Porsche model. The Turbo S model has a slightly higher drag coefficient of Cd=0.25. [47] [46] The frontal area is 2.33 m 2, with a resulting drag area of 0.513 m 2 and 0.583 m 2 for the Turbo and Turbo S, respectively. [48] [49] [50]

  8. Tatra 77 - Wikipedia

    en.wikipedia.org/wiki/Tatra_77

    The average drag coefficient of a 1:5 model of Tatra 77 was recorded as 0.2455. The later model T77a, introduced in 1935, has a top speed of over 150 km/h (93 mph) due to its advanced aerodynamic design which delivers an exceptionally low drag coefficient of 0.212.

  9. Rumpler Tropfenwagen - Wikipedia

    en.wikipedia.org/wiki/Rumpler_Tropfenwagen

    It was to be the first streamlined production car, before the Chrysler Airflow and Tatra T77. The Rumpler was already wind tunnel optimized at the Aerodynamics Research Institute in Göttingen [1] and had a drag coefficient of only 0.28, a value that astonished later engineers when they tested the Tropfenwagen in the 1970s.
