Grille technology can improve performance

　　While grilles come in all shapes and sizes, some technology using them can even improve performance. Many modern cars like the 2016 Chevy Volt and the 2016 GMC Canyon have aerodynamic technology that will close some of the grille grating when the vehicle is moving at top speeds. This reduces drag and improved aerodynamic flow. Other vehicles like the elite performance trims of the Chevy Camaro have specializes airflow paths built into the hood so that air can easily move through the engine and out in such a way that the Camaro can maintain its tight hold on the track and efficiently cool the radiator.
