Press Release
2014 Camaro Z/28 a Most Track-capable Camaro Ever
Chevrolet currently introduced a restyled 2014 Camaro line during a New York Auto Show, including a lapse of a Z/28, a many iconic indication in Camaro history.
The 2014 Camaro models underline a revised extraneous pattern that integrates high-performance aerodynamics for some-more fit cooling and fortitude during high speeds. The new Camaro Z/28 also facilities a full aerodynamics package that creates downforce during speed, that helps make it a many track-capable charity in Camaro’s history.
“As a ultimate track-capable Camaro, this automobile restores a idea of a strange Z/28, and serves as a covenant to a imagination of Chevrolet as a best-selling code of opening cars,” pronounced Mark Reuss, president, GM North America. “The build piece is a wish list of any racer: lightweight, high-revving, dry-sump LS7 engine; carbon-ceramic brakes; integrated coolers for lane use; loyal aerodynamic downforce, and a poignant rebate in quell weight. This automobile could usually come from Chevrolet, and could usually be called a Z/28.”
The initial Camaro Z/28 was introduced in 1967, combined to contest in a Sports Car Club of America’s Trans-Am 2 class. It featured a smaller, lighter, 302-cubic-inch V-8 for softened weight balance, as good as quick-ratio steering and a heavy-duty cessation for lane use. In gripping with a road-racing focus, a 1967 Camaro Z/28 was not accessible with an involuntary delivery or atmosphere conditioning.
While a new Camaro Z/28 is not dictated to contest in a specific competition series, it is usually focused on lane capability. In initial testing, a Camaro Z/28 is 3 seconds faster per path than a Camaro ZL1. That additional speed comes from 3 areas:
- Increased grip: The Z/28 is means of 1.05 g in cornering acceleration, due to extensive framework revisions
- Increased interlude power: a Z/28 facilities Brembo carbon-ceramic brakes means of 1.5 g in deceleration, and unchanging stop feel, path after lap
- Reduced quell weight: The naturally aspirated Z/28 weighs 300 pounds rebate than a supercharged Camaro ZL1, with changes trimming from lightweight wheels to thinner rear-window glass
Like a original, a 2014 Camaro Z/28 is offering usually with a primer transmission. In a curtsy to complicated convenience, air-conditioning is available, though usually as an option.
“We set out to make a fastest road-racing Camaro probable that was still street-legal,” pronounced Al Oppenheiser, Camaro arch engineer. “While a Camaro ZL1 offers well-developed opening on a street, a drag strip, and a track, a Z/28 is wholly focused on a lane performance. The Z/28 will be too track-focused for many drivers, though offers road-racers one of a many means lane cars ever offering from an automaker.”
The new 2014 Camaro line will arrive during Chevrolet dealers after in 2013. The Camaro Z/28 is approaching to be appearing during lane events opposite a United States in open 2014.
High-performance aerodynamics prominence changes for 2014 Camaro
The 2014 Camaro represents a many poignant redesign given a introduction of a fifth-generation Camaro as a judgment automobile in 2006.
“The 2014 Camaro is a event to request what we have schooled listening to a customers, and a fortitude growth of high-performance models,” pronounced Tom Peters, Camaro extraneous pattern director. “We demeanour for solutions that are both organic and pleasing so that a outcome is genuine Chevrolet – simple, powerful, honest, and some-more than expected.”
Compared to a prior model, a pattern represents a clever visible change front and rear, ensuing in a wider, lower, some-more contemporary appearance. The front fascia facilities a wider revoke opening, and a narrower top opening that also updates a coming of a iconic “halo ring” HID headlamps on a Camaro RS package. The organic hood opening on a Camaro SS helps revoke feverishness and aerodynamic lift. Moving to a rear, a sculptural decklid, plane lamps and diffuser finish a absolute statement.
The Camaro Z/28 also facilities a full aerodynamic package designed to furnish downforce during lane speeds. At a front, a Z/28 facilities a vast splitter, connected to an underbody row that serve reduces lift. In profile, a Z/28 facilities buffer flares over a front and behind wheels, as good as extended rocker panels that minister to aerodynamic stability. An assertive behind spoiler and organic diffuser finish a aerodynamic package.
On a interior, a Camaro Z/28 facilities trim in a distinctive, matte-metallic finish named Octane, a ZL1 flat-bottomed steering wheel, and customary Recaro seats with microfiber suede inserts. The new seats (also accessible on a coupe versions of a SS and ZL1 models), underline assertive bolsters for high-performance driving, as good as chair cutouts desirous by a five-point harnesses found on racing seats. To save weight, both front seats incorporate primer adjustment.
The behind seats of a Z/28 have also been mutated for weight reduction. A sum of 9 pounds (four kilograms) was saved by expelling a seat-back pass through, as good as regulating high-density froth in place of a firm structure of a chair behind and steel filigree of a chair bottom.
“Unlike a Ford Mustang Boss 302, we felt it was critical to keep a 2+2 pattern of a Camaro Z/28 as Chevrolet already has a world-class two-seat sports automobile in a Corvette,” pronounced Oppenheiser. “By modifying a construction of a behind seat, we were means to revoke a altogether weight of a Z/28 while still preserving a coherence of 2+2 seating.”
7.0L, LS7 a heart of a Camaro Z/28’s track-capable performance
Like a original, a new Camaro Z/28 forgoes ultimate horsepower and torque for softened weight change and lane performance.
In 1967, a most-powerful engine accessible in a bureau Camaro was a 396 cid V-8 with 375 horsepower. To ready a Camaro Z/28 for highway racing, engineers specified a lighter, 302 cid V-8, strictly rated during 290 horsepower. While a 302 was not a choice for drag racers, it valid ideal for sports-car racing.
Today, a most-powerful engine offering is a Camaro ZL1’s supercharged 6.2L LSA, that delivers 580 horsepower. The heart of a 2014 Camaro Z/28 is a lighter, naturally aspirated 7.0L LS7 initial introduced in a Corvette Z06.
“The LS7 is ideal for highway racing since it delivers extraordinary opening in a compact, lightweight package,” pronounced Jordan Lee, Small Block arch operative and module manager. “The extended torque bend and high redline of a LS7 meant fewer shifts are compulsory for any lap, while a lightweight pattern improves a front-to-rear weight change for softened handling.”
Co-developed with Corvette Racing, a hand-assembled 7.0L (427 cid) V-8 uses a series of high-performance components, including:
- Titanium intake valves and joining rods, and sodium-filled empty valves
- CNC-ported aluminum cylinder heads
- Forged-steel crankshaft and categorical temperament caps
- High-lift camshaft
- Hydroformed empty headers
- 11.0:1 focus ratio, and a 7,000 rpm redline.
- 10.5-quart, dry-sump oiling system
For a Camaro Z/28, a LS7 facilities unaccompanied initiation and empty systems, and delivers during slightest 500 horsepower (373 kW) and 470 lb-ft of torque (637 Nm).
The racing-style, cold-air initiation complement and vast KN atmosphere filter yield limit atmosphere flow.
The customary twin mode empty complement and larger-diameter pipes capacitate softened atmosphere flow. By bypassing a mufflers during acceleration, a complement increases both a torque and sound generated by a LS7 engine.
The Camaro Z/28 is exclusively offering with a Tremec TR6060 primer transmission. The six-speed facilities close-ratio gearing and 3.91:1 final expostulate ratio, both optimized for a energy characteristics of a LS7.
Power is distributed to a behind wheels around a limited-slip differential featuring a scrolled rigging set, rather than normal purchase packs. The new pattern enables a motorist to request some-more energy and get by corners faster, by invariably adjusting a torque disposition to maximize accessible traction.
The differential works in unanimity with Chevrolet’s exclusive Performance Traction Management system, that allows drivers to adjust a turn of stifle and stop involvement to compare their capability and pushing environment.
Unlike some competitors’ “track package” offerings, a Camaro Z/28 creates customary all a cooling systems compulsory for lane use. This includes a dry-sump oiling complement for a LS7, that is connected to an constituent liquid-to-liquid cooling complement for engine oil.
A second liquid-to-liquid complement provides cooling for a delivery and differential. This complement pumps overcooled delivery liquid to a feverishness exchanger in a behind differential before roving to a transmission. This reduces differential temperatures as many as 100 degrees F.
Camaro Z/28 framework delivers 1.05 g in cornering grip
The unaccompanied concentration of a Camaro Z/28 is many clear in a chassis, where a many has been done of each member for lane use, from a ultra-high opening tires to race-proven dampers.
“We used a really best components in a attention to broach uncompromised performance, path after lap,” pronounced Mark Stielow, Camaro Z/28 engineering manager. “We done scarcely 200 changes to urge a lane performance, that cumulatively make a Z/28 means of 1.05 g in cornering. For perspective, with all other things, equal augmenting limit hold from 1 to 1.05 g can cut adult to 4 seconds per lap.”
The Camaro Z/28 is a one of a initial prolongation cars propitious with race-proven, spool-valve dampers. Compared to a compulsory check that offers usually two-way tuning for strike and rebound, a spool-valve check allows four-way composition to precisely balance both strike and miscarry settings for high-speed and low-speed circle motions. The wider tuning operation authorised engineers to dramatically boost a check rigidity on a Camaro Z/28 though a poignant change in float quality. Additional framework changes embody stiffer fibre rates and cessation bushings for softened cornering response.
The Camaro Z/28 facilities 19-inch hole wheels and tires, that revoke unsprung weight by 42 pounds (19 kilograms) per automobile compared to a 20-inch wheels customary on Camaro SS and ZL1. In addition, a smaller hole wheels revoke a core of sobriety by 33 millimeters, serve improving handling.
At all 4 corners, a lightweight, fake aluminum wheels are wrapped in vast 305/30ZR19 tires. This is a initial prolongation focus of ultra-high opening Pirelli PZero Trofeo R tires, and believed to be a widest front tire on any prolongation car.
To entirely feat a hold of a Pirelli tires, a Camaro Z/28 also facilities Brembo Carbon Ceramic Matrix™ rotors and fixed, monoblock calipers. The vast 394 x 36 mm front rotors are interconnected with six-piston calipers, while a 390 x 32 mm behind rotors are interconnected four-piston calipers. Compared to similar-size, two-piece steel rotors, a lightweight CO discs save 28 pounds (12.5 kilograms) per car.
The multiple of tire hold and braking energy capacitate a Camaro Z/28 to grasp adult to 1.5 g in deceleration. With customary front stop cooling ducts, a Z/28 is also means of continual lane use unmatched stop feel, path after lap.
“What creates a Z/28 so addictive is it inspires certainty by each territory on a track,” pronounced Stielow. “The incredible, offset opening helps we lift many some-more speed by each corner: a brakes are so good we can adjust your braking points after and later; a hold and cessation damping allows we to lift some-more speed by a apex; and afterwards a singular trip allows we to make a many of a LS7 as we energy out of a corner.”
Extensive lightweighting saved 300 pounds over a Camaro ZL1
To optimize a lane opening of a Camaro Z/28, a engineering group subjected it to an complete lightweighting program, saving 100 pounds (45 kilograms) compared to a naturally aspirated Camaro SS and 300 pounds (136 kilograms) to a supercharged Camaro ZL1.
“We looked during each subsystem for opportunities to save weight,” pronounced Oppenheiser. “Our idea was to get absolved of all that didn’t make a automobile faster, and keep usually what was compulsory by law. For example, we wanted to discharge a audio complement completely, though we had to keep a singular orator for a seat-belt carillon to accommodate reserve requirements.”
Other examples of weight assets include:
- Eliminated a tire-inflator kit, solely for Rhode Island and New Hampshire, where it is compulsory by law
- Removed interior sound deadener, and carpeting from a trunk
- Replaced a customary LN4 battery with a smaller, lightweight, LN3 battery
- Specified thinner, 3.2-mm potion for a behind window, compared to 3.5-mm potion on a customary Camaro
- HID headlamps and foglights are not available
- Air conditioning is usually accessible as a stand-alone option
“The group was so immoderate about saving weight, we even nude a new wiring out of a strap when we separated a haze lights, speakers, and atmosphere conditioning,” pronounced Oppenheiser. “Every unit saved contributed to creation this a many track-capable Camaro we have ever built, and a estimable inheritor to a Z/28 name.”
