Chevy FlowtieWhen you see a golden bowtie, you know you're looking at a Chevrolet. And that's completely by design. First introduced way back in 1913, the famed Bowtie has gone through several permutations, but it's never quite been modified like it has for the new Chevy Camaro Z/28. Instead of a solid bow, as we've become accustomed to seeing, the Z/28's Bowtie is hollow.

According to Chevy's press release, which can be found below, Powertrain Cooling Development engineer Richard Quinn noticed during wind-tunnel testing that the Z/28's Bowtie-emblazoned grille was pushing air away instead of allowing it to hit the radiator. The solution was to cut out the center of the emblem, leaving a chrome outline that lets air through.

GM's engineers have named the new Bowtie-shaped emblem the Flowtie. Clever, boys. An additional three cubic meters of air is let into the engine bay per minute, lowering coolant and oil temperatures by 2°F.

Modified Chevrolet Bowtie Makes Z/28 Even Cooler
Traditional badge modified in the name of all-out track performance.

DETROIT – In developing the 2014 Camaro Z/28, the team scrutinized every component looking for ways to improve track performance, lap after lap. Even the iconic Chevrolet bowtie faced audit.

During aerodynamics testing, Powertrain Cooling Development engineer Richard Quinn noticed that the bowtie on the Z/28's grill was displacing air away from the radiator, which can impact engine cooling – an important aspect for all vehicles, especially track-oriented cars.

Removing the bowtie altogether did not seem to be an appropriate solution. Instead, Quinn took a cut-off wheel to the gold fill of the bowtie, leaving the silver outline intact. He installed the prototype on the grill and retested to see the results.

"There are engineers in our team that race as a hobby," said Quinn, "and we used that racer's mindset to look for ways small or large to get better performance out of the Z/28. Even the smallest details on the Z/28 were weighed for cooling benefit, and this is one that stuck."

The "Flowtie," as the engineers now affectionately refer to it, is just the chrome outline of the traditional bowtie, with the center removed. This simple solution alone was enough to allow three additional cubic meters of air into the engine per minute. Engineers found the Flowtie dropped the temperatures of engine coolant and engine oil by 2°F (1.2°C) during extended track sessions. That seemingly small improvement was enough to justify making the Flowtie standard on every new Z/28.

"The Flowtie is just one example of the team's focus on track performance," said Al Oppenheiser, Camaro chief engineer. "That same attention to detail is evident throughout the cooling systems for the LS7 engine, as well as the carbon ceramic brakes and the differential."

The naturally aspirated Z/28 weighs 300 pounds less than the supercharged Camaro ZL1 and 55 pounds lighter than the Camaro 1LE - with changes ranging from lightweight wheels to thinner rear-window glass.

"The Camaro Z/28 has more than 190 unique parts, compared to a Camaro SS," Oppenheiser said. "Like the Flowtie, each of these parts were changed with one objective: to deliver incredible performance on the track – not just for the first lap, but lap, after lap, after lap."

The 2014 Camaro Z/28 arrives in dealerships this spring.

      Hell, I like it better! The gold bowtie is cheesy looking.

        Yes, but that's an observation that easily carries to the entire car, so in for a penny...

      I wonder how much airflow is restricted by (Some States) mandating license plates on the front of a car?

        Depends on how, where and if it's mounted. I say if because let's face it--especially in California--how many cars do you see every day missing a front plate?

        Much of the "grille" on modern cars does not actually open to the engine bay. Unless one things than an A4 has the cooling needs of a P51 Mustang. It's cosmetic. I don't think's generally an issue. The Automaker and move the "open" part of the grille away from the plate mount usually quite easily.

      I wonder if they considered a clip-on Bowtie.
      • 1 Year Ago
      When is GM going to raise the price on it?
      • 1 Year Ago
      Or if you want to go fast around a track just get a Z51 vette and save some money.

      This makes sense and probably doesn't cost, how long until this is applied to all GM models with an emblem in the grille? We shall see.

        GM is more concerned with aero drag than cooling in most of their line-up. That's why grills are getting smaller, or have shutters.
      • 1 Year Ago
      Clearly GM is capable of actual engineering. They just need to do it more consistently.

        White with blue trim? ...Yeah, I'd rock that.

      Not the first Flowtie! I guess my 1992 Z24 was a technological marvel of it's time with a Flowtie:

      Why not mount the bowtie on the bumper or hood where no flow would be obstructed?
        • 1 Year Ago
        Because then it would look like a gaudy Caprice.
      • 1 Year Ago
      A smaller bow tie would've been my solution

      Hollow Bowtie for a hollow company. Never trust a man in a bowtie. Real men don't wear bowties.

        Bill Nye wears a bow tie and he is unquestionably awesome.
