1. "They represent around 64 percent of the aerodynamic drag , " he gripes. 2. The body completely engulfs the wheels this eliminating their additional aerodynamic drag . 3. The canopy will be as aerodynamically shaped as possible to minimize aerodynamic drag . 4. The Sierra filled the requirements for rear wheel drive and decent aerodynamic drag . 5. By riding behind the'lead out'rider, the second rider reduces the aerodynamic drag felt. 6. Aerodynamic drag was reduced, with three-bladed metal propellers that were theoretically more efficient.7. Using a 3-wheel configuration, the rolling and aerodynamic drag is reduced. 8. In spite of its unstreamlined wheels, its aerodynamic drag coefficient was only 0.30. 9. Open windows create substantial aerodynamic drag at highway speeds, which uses up fuel. 10. The wake is to be expected and is the cause of aerodynamic drag .
