From racetrack to worksite: Chevrolet’s all-new 2019 Silverado chassis cab trucks adopt racing-inspired flowtie

LAS VEGAS — The all-new #chevrolet #silverado 4500HD/5500HD/6500HD trucks took a design cue from an unlikely source: the #chevrolet #camaro. The “flowtie,” first introduced on the front grille of the 2014 #camaro Z/28 and now standard on the 2018 #camaro ZL1, is the chrome outline of the traditional #chevrolet bowtie but with the center removed, allowing increased engine airflow to help improve performance.

“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.”

Why a flowtie?

During Z/28 aerodynamics testing, engineers noticed that the bowtie on the grille was displacing air away from the radiator, which can impact engine cooling. So, propulsions engineer Richard Quinn took a cut-off wheel to the bowtie’s gold fill, leaving the silver outline intact. He installed the prototype flowtie on the grille and a retest revealed that it allowed more air into the engine, lowering engine fluid temperatures during extended track sessions.

The conventional cab Silverados are heavy-duty cycle trucks, and the designers needed a solution that allowed for maximum airflow with the truck’s pumped-up grille. They found their solution in the performance car toolbox.

“The flowtie is an elegant solution. And it’s going to work on the #silverado exactly the way it does on #camaro,” said O’Donnell.

Other exterior design highlights:

  • Muscular look with a broad wide bumper, strong center bar and fenders that grow out of the hood
  • A powerful hood form that maintains downward range of sight to provide driver perspective
  • Fiberglass tilt-hood with integrated hand grips to aid serviceability
  • Cab with inlaid doors and triple door seals for in-cab quietness

“Chevy’s designers and engineers were obsessed with making this #silverado the most customer-focused medium-duty truck among its major competitors — and this is evident in every design decision,” said Ed Peper, U.S. vice president, GM Fleet.
