When it comes to making cars faster on the raceway, it is amazing to see the level of detail that goes into squeezing out an extra fraction of a second. In the case of Chevrolet’s 2014 Camaro Z/28, even the little logo on the grille can make a difference.
Like every Chevrolet, the Camaro carries the little Chevy logo on its front, what’s known within the company as the “bowtie” because of its shape.
During aerodynamics testing, engineer Richard Quinn noticed that the bowtie on the Z/28’s grille was blocking air away from the radiator. Not a lot, but enough that it could potentially make a difference when it comes to engine cooling.
