The name XD came from oddly shaped rear lights (X-shaped) and "D" beginning letter of the company's name.(they have changed the name since then) [2] Loox can travel over 250 km on a single charge with lithium iron phosphate batteries. [3] The car has a low drag coefficient factor of only 0.35.
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 ...
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.
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 design emphasizes mainstream rather than exotic materials, extreme low weight (less than 450 kg (1000 lbs)) and very low aerodynamic drag (coefficient of drag <0.16). [4] Significant design innovations include in-wheel suspension and safety design derived from endurance auto racing.
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 ...

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.
