Chevy’s 2019 Colorado ZR2 Bison is packed with unique features that make it the ultimate midsize off-road truck. From purpose-designed bumpers, skid plates, and snorkel, the teams at Chevy and AEV really put some thought into making this one really capable truck. But besides the truck’s various off-road parts, the Colorado ZR2 Bison also features a new kind of lettered Chevy Flowtie.

Chevy flowtie on 2019 Chevrolet Silverado Medium Duty truck
Four years ago, Chevy introduced a unique version of its bowtie logo on the 2014 Camaro Z/28. The logo is unique in that the inside of the logo is hollowed out, only leaving the silver outline. The new-style Chevy logo was christened as the flowtie.
In the case of the Camaro Z/28, engineers noticed that the flowtie improve airflow to the radiator, allowing three additional cubic meters of air into the engine per minute, while dropping engine coolant and engine oil temperatures by 2°F (1.2°C) during extended track sessions.
Since then, the flowtie logo has made its way to other Chevy vehicles, including the sixth-gen Camaro ZL1, 2019 Silverado Medium Duty, and the 2019 Camaro SS. The newest vehicle to adopt the technology is the Colorado ZR2 Bison, though it does it in a rather unique way.
You see, the Colorado ZR2 Bison has a front fascia that has CHEVROLET spelled out across the grille. Each of those letters is hollowed out, in turn providing better airflow to cool the engine and associated powertrain components. In many ways, it’s like another version of the flowtie, without the actual Chevy bowtie logo.
So while the Colorado ZR2 Bison won’t be doing any high speed bombing around a race track anytime soon (unless someone is crazy enough to try), additional powertrain cooling is (almost) never a bad thing.
It’s worth noting that the Chevrolet-lettered grille in question, along with its flowtie-like qualities, is also available as an official GM/Chevrolet accessory. Assigned LPO code RZB, it is compatible with Work Truck, LT, and Z71 trim levels, and not compatible with the Base or the ZR2 models.
Comments
This story where ever it came from is kind of stretching it.
This is the dealer option grill for all Colorado’s and many have already been installed. Nice option.
Agreed. The 2019 Silverado Custom has the same CHEVROLET style grille, neither truck *really* needs the additional cooling achieved by hollow lettering.
Where the story came from is close attention to detail.
So, is this NOT a new kind of flow tie, Scott?
I see a flow Chevrolet. Where is the Tie?
Ok i am game if you are trying to say this with a straight face.
So just how much more CFM is gained?
How much has it dropped cooling assuming the shutters are open on the radiator.
What is the additional square inches of cooling is this?
Will it fit a ZR2 since that nose and bumper is slightly different.
I assumed this was just a lame GM press release buy I guess it is just a lame story from….. well never mind lol!
Looks like you’re the one stretching here.
“I see a flow Chevrolet. Where is the Tie?”
That statement proves that there isn’t another term besides “flow tie” for the feature in question. Calling it flow Chevrolet is just dumb and would not make sense.
“So just how much more CFM is gained?
How much has it dropped cooling assuming the shutters are open on the radiator.
What is the additional square inches of cooling is this?”
You’re asking questions the answers to which nobody outside of GM/Chevrolet knows… and they’re not sharing it.
“Will it fit a ZR2 since that nose and bumper is slightly different.”
Another unknown, but it is listed as available from the GM partner parts distribution centers (AD) as available on WT, LT and Z71, and not avaialble on Base or ZR2.
“I assumed this was just a lame GM press release buy I guess it is just a lame story from….. well never mind lol!”
Lame to who? To you?
Here’s the bottom line: this is a feature that is unique for the 2019 Colorado. And for being unique, it is worthy of being highlighted, as it is new.
Notably, GM Authority is the only one that seems to have noticed and written about it… which should be recognized as a plus, rather than idiotically critiqued.
Now, if you don’t find it appealing, simply don’t read the story. I would hope that no one is forcing you to do so.
The fact that you’re the only one who has some kind of a problem here while thousands of others who have read this article today alone are perfectly content and happy says it all.
So outside of being a curmudgeon, does your comment have any other purpose?
Comment section is here to comment and share thoughts and opinions. We don’t need to agree with Herr Authority.
I’m with Scott.
It’s like that other article yesterday about Nissan Xterra having bumper steps first. No validity, just something that could make for a blog post. Meanwhile it was quickly shot down that the Avalanche had them years prior
What is your beef exactly, Herr Andrew?
The comment section exist to have a productive conversation that adds value to the topic at hand, not to lambast something with no rhyme or reason.
I’m about to delete this whole thread, as your and scott’s lame excuses for comments on this thread serve none of these purposes.
And allow me to remind you that commenting here is a privilege. Not a right.
PS: you might want to revisit that corner step article.
