It's so simple, and yet utterly a thing of true genius.
We knew from the get-go that the new Chevrolet Camaro Z/28 was one hell of an incredible car, especially on the track. Aerodynamics obviously plays a huge role, but during testing, the Z/28’s Powertrain Cooling Development engineer realized something most wouldn’t have. That famous Chevy bowtie on the Z/28’s grille was actually displacing air away from the radiator. This minor, though relevant issue, was deflecting air away from the radiator, which can affect engine cooling.
The solution turned out to be very, very simple: instead of removing the bowtie altogether, this engineer created the "Flowtie," a chrome outline of the bowtie with the center removed. And, low and behold, the "Flowtie" helped decrease engine coolant and oil temperatures.
