When you see a golden bowtie, you know you are looking at a Chevrolet. And that is completely by style. Very first introduced way back in 1913, the famed Bowtie has gone via several permutations, but it really is in no way quite been modified like it has for the new Chevy Camaro Z/28. Rather of a reliable bow, as we’;ve turn out to be accustomed to seeing, the Z/28’;s Bowtie is hollow.
According to Chevy’;s press release, which can be discovered below, Powertrain Cooling Development engineer Richard Quinn noticed in the course of wind-tunnel testing that the Z/28’;s Bowtie-emblazoned grille was pushing air away as an alternative of permitting it to hit the radiator. The answer was to minimize out the center of the emblem, leaving a chrome outline that lets air by way of.
GM’;s engineers have named the new Bowtie-shaped emblem the Flowtie. Clever, boys. An added 3 cubic meters of air is let into the engine bay per minute, lowering coolant and oil temperatures by 2°F. Scroll down below for more data from Chevy about its so-referred to as Flowtie and to observe a video.
Classic badge modified in the name of all-out track functionality.
DETROIT – In creating the 2014 Camaro Z/28, the team scrutinized every single element looking for techniques to improve track performance, lap soon after lap. Even the iconic Chevrolet bowtie faced audit.
Throughout aerodynamics testing, Powertrain Cooling Growth engineer Richard Quinn observed that the bowtie on the Z/28’;s grill was displacing air away from the radiator, which can influence engine cooling – an crucial element for all vehicles, especially track-oriented autos.
Getting rid of the bowtie altogether did not look to be an suitable resolution. Rather, Quinn took a lower-off wheel to the gold fill of the bowtie, leaving the silver outline intact. He put in the prototype on the grill and retested to see the final results.
“There are engineers in our crew that race as a hobby,” stated Quinn, “and we utilised that racer’;s mindset to seem for approaches small or huge to get much better efficiency out of the Z/28. Even the smallest specifics on the Z/28 had been weighed for cooling advantage, and this is a single that stuck.”
The “Flowtie,” as the engineers now affectionately refer to it, is just the chrome outline of the traditional bowtie, with the center eliminated. This simple remedy alone was adequate to let 3 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) in the course of extended track sessions. That seemingly small improvement was adequate to justify generating the Flowtie common on each and every new Z/28.
“The Flowtie is just one instance of the team’;s target on track efficiency,” explained Al Oppenheiser, Camaro chief engineer. “That very same focus to detail is evident during the cooling systems for the LS7 engine, as effectively as the carbon ceramic brakes and the differential.”
The naturally aspirated Z/28 weighs 300 pounds less than the supercharged Camaro ZL1 and 55 lbs lighter than the Camaro 1LE – with modifications ranging from light-weight wheels to thinner rear-window glass.
“The Camaro Z/28 has much more than 190 unique components, compared to a Camaro SS,” Oppenheiser mentioned. “Like the Flowtie, every single of these elements have been changed with 1 objective: to supply outstanding efficiency on the track – not just for the initial lap, but lap, soon after lap, right after lap.”
The 2014 Camaro Z/28 arrives in dealerships this spring.
