In the race for the reduction of fuel consumption and emissions of CO2 in the atmosphere of General Motors engineers to model Chevrolet Cruze Eco designed radiator grille with active dampers (shutters), which regulate air flow to cool the radiator.
Depending on the degree of opening of the shutter is changing the nature of the flow front of the Chevrolet Cruze Eco. When fully closed flaps drag coefficient decreases. To control the damper actuator is used.
At high speeds to reduce aerodynamic drag flaps are closed, and at low speeds, on the contrary, open. This system of regulation of air supply allows you to save as much fuel to further drive in the city and in the combined cycle, almost 1 kilometer. It is worth noting in passing that to improve the aerodynamics engineers reduced the ground clearance and weight of the car.
