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 ...
The idea was to create vehicles with the lowest possible drag coefficient. All the cars featured large rear bumpers and curved fins. They were built upon the Alfa Romeo 1900 chassis. 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 ...
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.
As the size of the car prohibited meaningful wind tunnel testing, the streamlined shape of the car was refined entirely through the use of computational fluid dynamics by MIRA Ltd, which has enabled the car to obtain a very low coefficient of drag of only 0.147 and a C d A value (drag coefficient × frontal area) of only 0.129 m 2. The fuel ...
The Aptera has a claimed coefficient of drag that is very low, at 0.13 as of January 2023. [14] The car was tested at an Italian wind tunnel, the results of which were described by co-CEO Chris Anthony as "pretty pictures".

Rear view Interior. When production of the Hyptec GT begins, it will have the lowest-ever wind resistance coefficient of any mass-production car at 0.19 cd. The GAC research and development team used aerodynamic design cues featured in previous concepts such as the GAC ENO.146 and TIME to achieve the low drag coefficient of the Hyptec GT.
A new car that costs under $20,000, once an unofficial threshold of affordability, is all but history in the United States. Blame it on automakers abandoning the low-profit small-car business as ...
