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.
Rolls Royces says the flowing robes of the ornament were reshaped to be more realistic and are lower, making the ornament more aerodynamic. The new ornament stands 83 mm (3.3 in) tall, compared to the predecessor's 100 mm (3.9 in), [ 9 ] and bringing it closer to the earlier examples. [ 10 ]
The Subaru XT is a two-door, front- or all-wheel drive, four passenger 2+2 coupé [1] manufactured and marketed by Subaru for model years 1985-1991, with a facelift in 1987. . At introduction, the XT was the most aerodynamic car marketed in the US market, [1] heavily influenced by noted designer Alex Tremul
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).
[9] [10] Its automobile drag coefficient is as low as 0.20, making it the most aerodynamic car in production at the time of its introduction. [11] [12] The car is powered by a water-cooled permanent magnet synchronous motor from Valeo Siemens in the EQS 450+ model, and by two of these motors in the EQS 580 4MATIC model. The torque is sent from ...
[5] [10] The Calibra remained the most aerodynamic mass production car for the next ten years, until the Honda Insight was launched in November 1999, with a Cd of 0.25. [11] All later 16V, V6, 4x4 and turbo models had a worse Cd of 0.29, due to changes in cooling system, underbody, use of spoked wheels and glass detail. [12]
The Trans Am body would continue to improve aerodynamically over the years, and by 1985 would be the most aerodynamic vehicle to ever be released from General Motors with a 0.29 coefficient of drag. Wind tunnels were used to form the third-generation F-Body's shape, and these aerodynamic developments were fully taken advantage of by Pontiac's ...
The Calibra coupé followed in 1989, which was officially the most aerodynamic production car in the world on its launch. Falling between the Cavalier and Senator was the Opel-built Carlton (Opel Rekord and later Opel Omega elsewhere) – relaunched in 1986, and was voted 1987 European Car of the Year , a large four-door family saloon.
