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.
SCOTTSDALE, Ariz. – Chevrolet will auction the rights to purchase the first retail-production 2014 Camaro Z/28 and the first limited-production 2014 COPO Camaro this week at the Barrett-Jackson Scottsdale collector car auction with proceeds going to education and veteran empowerment groups.
The COPO Camaro will cross the block first, on Friday evening, Jan. 17, and Fox Business News will air the auction live. Carrying serial No.1 for 2014, the race car features a new, LS-based supercharged 350-cubic-inch engine and a one-off COPO Ice Blue Metallic satin paint scheme. Proceeds will benefit the Achilles Freedom Team of Wounded Veterans.
The Camaro Z/28 – with the vehicle identification number ending in 0001 – is being sold on Saturday evening, Jan. 18, to benefit Detroit’s Cornerstone Schools. The National Geographic Channel will broadcast the auction.
Bids for both cars can be submitted in person at the auction or online at barrett-jackson.com.
“Chevrolet is excited to offer these two milestone cars for the Barrett-Jackson bidders, with all the proceeds going to help a pair of very worthy groups,” said Jim Campbell, General Motors U.S. vice president of Performance Vehicles and Motorsports.
The Achilles Freedom Team of Wounded Veterans is dedicated to helping wounded veterans participate in marathons and share their success within a supportive community and their families. The Cornerstone Schools, lauded as a model in urban education, have a 95-percent graduation rate and 91 percent of graduates pursue higher learning.
In addition to the sales of the Z/28 and COPO Camaro, a Chevrolet display at the event showcases the cars, along with performance-enhancing parts that can be added to regular-production Camaros. They include COPO Camaro drag-racing components and street- and track-level components for Camaro V-6 and SS models, including 1LE suspension and ZL1 brake upgrades.
The parts are available through the Chevrolet Performance catalog, available from Chevrolet dealers or downloadable for free at chevrolet.com/performance.
Also on display are concept suspension, induction and exhaust parts derived from the new Z/28, which are being evaluated for possible future release.
2014 Camaro Z/28
The 2014 Camaro Z/28 is the fastest production Camaro ever on a track, with unique exterior elements designed like a race car to produce downforce, pressing the tires against the track for greater grip – up to 1.08 g in cornering acceleration – and faster lap times.
The aerodynamically optimized design helped the Camaro Z/28 log a 7:37.40 lap on Germany’s Nürburgring road course. The Z/28’s lap is four seconds faster than the Camaro ZL1, and it beats published times for the Porsche 911 Carrera S and the Lamborghini Murcielago LP640.
Power comes from the 7.0L LS7 engine, with dry-sump oiling, rated at an SAE-certified 505 horsepower (376 kW) and 481 lb-ft of torque (652 Nm). It is built by hand at the new Performance Build Center within GM’s Bowling Green, Ky. assembly plant.
A close-ratio six-speed manual transmission is the only transmission offered and power is distributed to the rear wheels via a Torsen limited-slip differential featuring a helical gear set, rather than traditional clutch packs, to make the most of traction. The Camaro Z/28 is also one of the first production cars fitted with race-proven, spool-valve dampers, which allow four-way damping control, enabling engineers to precisely tune bump-and-rebound settings for high- and low-speed wheel motions.
It arrives in dealerships in spring.
