Just like the 2014 Camaro Z/28 and the 2018 Camaro ZL1, the all-new 2019 Chevy Silverado 4500HD/5500HD/6500HD heavy duty trucks have a race-inspired “flowtie” of their own.
The flowtie is the chrome outline of the Chevy bowtie logo, but without the center part, which allows improved engine airflow and results in better performance.
“There is innovation in the design details and a great example is our Camaro Z/28-inspired Chevrolet flowtie,” stated Chevrolet 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.”
During Z/28 aero tests a few years ago, engineers noticed that the car’s bowtie grille badge was displacing air away from the radiator. That’s when propulsion engineer Richard Quinn went to work and took out the bowtie’s gold fill, leaving only the silver outline intact. Thus, more air was allowed into the engine, lowering fluid temperatures during extended periods on the track.
The same principle is applied to heavy duty Silverados. “The flowtie is an elegant solution. And it’s going to work on the Silverado exactly the way it does on the Camaro,” said O’Donnell.
The 2019 all-new Silverado chassis cab also features a muscular appearance, a fiberglass tilt-hood that allows for downward range of sight for the driver, plus inlaid doors and triple door seals for in-cab quietness.
