Chevrolet presents a new feature of the 2014 Camaro Z/28. The brand's bowtie was actually displacing air away from the radiator, which affects engine cooling.

So Powertrain Cooling Development engineer Richard Quinn came up with a way to replace the golden bowtie with just the chrome outline of the shape. They tested the results:

“There are engineers in our team that race as a hobby 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,” Quinn says.

The "Flowtie" appears a minor detail to some but it actually improves the cooling efficiency by allowing three additional cubic meters of air into the engine per minute.

Engineers found the Flowtie dropped the temperatures of the engine coolant and engine oil by 2°F (1.2°C) during extended track sessions, so they decided to make it a standard feature on every CamaroZ/28.
