Whether or not there's a big performance benefit, the flowtie looks great on the front of these work trucks.

Buyers of Chevrolet's new chassis cab trucks can tout having a feature previously exclusive to the meanest versions of the Camaro – the flowtie. The 2019 Silverado 4500HD, 5500HD, 6500HD models adopt this novel version of the brand's venerable emblem that has no center section to aid airflow through the grille. The border around it is chrome, so there's still a flashy touch at the front end of the trucks.

These work trucks won't be lapping the Nürburgring anytime soon, but the flowtie can still bring some small advantages in getting more air into the engine bay to keep things running cool.

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

 

Chevy introduced the new chassis cab trucks in early March. The company put an emphasis on better usability and easier servicing for the latest models. The redesigned front end allegedly gives drivers better downward visibility for the driver, which is especially useful for maneuvering at a tight job site. Fifty-degree wheel cuts allow for tighter turning, too. Mechanics reportedly have better access under the hood, too.

Inside, drivers benefit from modern amenities. There are helpful features like a wireless cellphone charging, Bluetooth, Apple CarPlay, and Android Auto.

All of these pickups come with a 6.6-liter Duramax diesel engine with 350 horsepower (261 kilowatts) and 700 pound-feet (949 Newton-meters) of torque. Buyers can pick between two- and four-wheel-drive configurations, and there are multiple chassis length options for adapting the vehicle into various uses. A rear air suspension is available, too.

The new Silverado 4500HD, 5500HD, 6500HD will be on sale in late 2018.

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.
