My research question is how super cars can improve their aerodynamics. I will talk about a specific brand of super car, Nissan GTR. The Nissan GTR is the only car which needs to pay the luxury tax in Nissan. Because Nissan GTR’s price is more than a hundred thousand dollars. It is a powerful super car and has a special name called god of war. The reason that makes the Nissan GTR runs so fast is it take full advantage of the air power. This technology is called aerodynamics. The new 2015 Nissan GTR changed its normal headlights to a Multi-LED Headlights. It has a system called Adaptive Front lighting System to control these four LED lights. The lights will turn together when the car is cornering. Between these two headlights there is a big spoiler. The spoiler is creating down force to keep the car on the ground. The vents behind the front fenders are not only creating more down force but also cooling the brakes. There is a big grille between two headlight can get more air to cool down the engine. The cooling system is very important for a powerful car. The new GTR has a 3.8-liter Twin-turbocharged V6 Engine. This engine is hand-assembled by a single technician in a dust-free, temperature-controlled clean room. The GTR has a 6-speed sequential dual-clutch transmission. It can shifts as quickly as 0.15 seconds. These two part are the most important things in the car, like the heart. Because of these two part, the GTR can speed up from 0km/h to 100km/h for about 3.8 second. A sport car must has a great Braking System. It has two 6-piston front brakes and two 4-piston rear brakes. These big brakes can make the GTR stop when the driver wants it stop. (Nissan – Official Site) Super cars’ speed can improve if the aerodynamic of the super cars can decrease the air friction. When the super cars drive at high speed, the air friction will become bigger and bigger. It’s very important to decrease the air friction for a super car. The super cars usually have the wide body kit which is based on the aerodynamic technology. The wide body kit can help the super car break the air easily like the bullet. Super cars’ performance can improve if the aerodynamic of the super cars can make enough down force. In Katz Joseph’s article Annual Review of Fluid Mechanics, “In those years, cornering acceleration grew from less than the gravitational acceleration (g) to close to 4g due to the increased use of aerodynamic down force.” (30). Aerodynamic down force can improve the controllability of the super cars. Today a lot of super cars can run over 300km/h. The airplane can take off at 300 km/h, but the super cars should not leaving ground. The down force can help the super cars keep the tires on the ground, like a big hand hold on the car. It also can increase the traction when the super cars are turning.
