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.
The smooth body of the T77a gave a coefficient of aerodynamic drag of 0.212. Some sources, though, claim that this figure was based on a 1:10 scale-model test, and it has been confirmed recently that the drag coefficient for the real full-size car is 0.36. [8] [9] [10]
The Kammback, along with other aerodynamic modifications, gave the prototype a drag coefficient of 0.25. [12] The earliest mass-produced cars using Kammback principles were the 1949–1951 Nash Airflyte in the United States and the 1952–1955 Borgward Hansa 2400 in Europe. [7]
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.
In 2021 and 2022, Autocar and Auto Express named it as one of the best hardcore sports cars. [181] [182] [183] Road & Track mentioned the GT-R as one of the best daily drivers, while Evo Magazine claimed it as one of the best coupes in 2022. [184] [185] Carwow temporarily named the GT-R as one of the best sports cars of 2023. [186]
It can accelerate from 0–100 km/h (0–62 mph) in 2.8 seconds and attain a theoretical top speed of 439 km/h (273 mph). The Agera R has a drag coefficient of Cd=0.37, or Cd=0.33 at high speed due to its adaptive rear wing, while producing 300 kg (660 lb) of downforce at 250 km/h (155 mph). This adaptive rear wing system is lighter than ...
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]
Each of the three cars was presented at the Turin Auto Show, in 1953, 1954 and 1955 respectively. 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 ...
