Since Ra27 is the second generation Solar Car of Near East University Solar Racing Team has some experience. Ra25 was a looking beautiful car but had too much aerodynamic drag on it. So this new car had to be designed from the scratch with keeping in mind what was wrong on the previous car.
Ra27 design is based on several NACA airfoil designs. Body is a from of a supersonic wing design. This design will make the wind speed very fast on the center of the car which creates low pressure on the most heaviest part which is carrying the driver and the batteries. Also canopy and wheel cover designs are based on NACA airfoil designs.
