GM Says “Flowtie” Improves Airflow

A little change makes a big difference to engine cooling in the all-new Silverado HD.

The “flowtie,” first introduced on the front grille of the 2014 Camaro Z/28 is now proudly displayed on the all-new Chevrolet Silverado 4500HD/5500HD/6500HD.

The flowtie is basically the the chrome outline of the Chevrolet bowtie, but with the centre removed, allowing increased engine airflow to help improve engine cooling and performance, says GM.

“There is innovation in the design details and a great example is our Camaro Z/28-inspired Chevrolet flowtie,” said Design Manager Kevin O’Donnell. “Our engineers designed it to help win races by using airflow to lower coolant and oil temperatures on the race track.”

That concept is now making its way into the HD where the flowtie allows more air into the engine, lowering engine fluid temperatures. And since the all-new Silverado HD models are heavy-duty cycle trucks, the designers needed a solution that allowed for maximum airflow, and they found it in the flowtie.
