  1. The Camaro Z/28 will be returning for an encore act and it might be using the next-generation of Chevrolet's small-block V8. Car and Driver reports that GM is working on the next-generation LT engines, codenamed LT6 and LT7. These new V8 engines will lose the pushrods and two-valve combustion chambers that have been a key part of the small-block V8. Instead, the new engines will feature dual overhead camshafts, four-valve combustion chambers, flat crankshaft, titanium connecting rods, and possibly dual injection (port and direct). For the Z/28, a 5.5L LT6 could produce 700 horsepower (that's without any sort of forced induction). Car and Driver speculates there could also be a twin-turbo LT7 that could be used in the next Corvette, high-performance Camaros, and Cadillacs. The Camaro Z/28 could arrive next year as a 2019 model year vehicle. Source: Car and Driver

  3. Chevrolet has announced the pricing for the upcoming 2014 Camaro Z/28 before it goes on sale in the spring. The base price will be $75,000 (includes a $995 destination charge and a gas-guzzler tax). While the pricetag is a bit extravagant at first glance, the number of performance parts that make the Z/28 a road going racecar more than justify it. Let's begin with what's under the hood of the Z/28: A 7.0L LS7 V8, rated at 505 horsepower and 481 pound-feet of torque. A six-speed manual transmission with a Torsen limited-slip differential that makes sure all of that power to the rear wheels. Other changes include a weight loss of 300 pounds, light-weight nineteen-inch alloy wheels wrapped in Pirelli PZero Trofeo R tires, new dampers, carbon-ceramic Brembo brakes, new body pieces, and and microfiber Recaro seats. There is only one option package available; for $1,500 you can get air conditioning and and a six-speaker audio system. Source: Chevrolet William Maley is a staff writer for Cheers & Gears. He can be reached at [email protected] you can follow him on twitter at @realmudmonster. Press Release is on Page 2 2014 Chevrolet Camaro Z/28 Priced at $75,000 DETROIT – Chevrolet today announced the 2014 Camaro Z/28 will go on sale this spring with a suggested retail price of $75,000, including a $995 destination charge, but excluding tax, title, license and dealer fees. The new Z/28 is offered in five exterior colors – Red Hot, Black, Silver Ice Metallic, Ashen Gray Metallic and Summit White. Only a single option is available: A $1,150 package that adds air conditioning and a total of six audio speakers. The standard Z/28 package includes one speaker. "The Camaro Z/28 is an uncompromising performer that's bred for the track – and every one of its unique components supports the goal of faster lap times," said Mark Reuss, president, General Motors North America. "It takes the Z/28 back to its racing roots and adds to the strong lineup of Chevrolet performance cars, including a revamped Camaro SS and supercharged ZL1, as well as the SS sedan, Corvette Stingray convertible and 2015 Corvette Z06, which we'll introduce at the North American International Auto Show next week." The Z/28's unique exterior is designed like a race car to produce downforce that presses 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 lap on Germany's legendary Nürburgring road course that was four seconds faster than the Camaro ZL1's and beat 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). The engine will be built by hand at the new Performance Build Center within GM's Bowling Green 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, for optimal traction. The differential works in unison with Chevrolet's proprietary Performance Traction Management system, allowing drivers to adjust the level of throttle and braking intervention to match their capability and driving environment. 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 both bump and rebound settings for high-speed and low-speed wheel motions. The wider tuning range also allows dramatically greater damper stiffness without a significant change in ride quality. Additional chassis changes include stiffer spring and bushing rates for improved cornering response. Lightweight, 19-inch forged aluminum wheels and Pirelli PZero Trofeo R tires reduce unsprung weight by 49.6 pounds (22.5 kilograms) per car compared to the 20-inch wheels standard on Camaro SS and ZL1. The massive 305/30ZR19 PZero Trofeo R tires represent the first production-car application in the industry and are believed to be the widest front tire on any productioThn car. To fully exploit their grip, the Z/28 also features Brembo Carbon Ceramic Matrix™ rotors and fixed, monoblock calipers. The large 394 x 36 mm front rotors are paired with six-piston calipers, while the 390 x 32 mm rear rotors are paired four-piston calipers. Compared to similar-size, two-piece steel rotors, the lightweight carbon discs save 28 pounds (12.5 kg) per car. The combination of tire grip and braking power enable the Camaro Z/28 to achieve at least 1.5 g in deceleration. With standard front brake cooling ducts, the Z/28 is also capable of continuous track use. Interior details On the interior, the Camaro Z/28 features trim in a distinctive, matte-metallic finish called Octane, a flat-bottom steering wheel and Recaro seats with microfiber inserts. The seats feature aggressive bolsters for high-performance driving, as well as seat cutouts inspired by the five-point harnesses found on racing seats. To save weight, both front seats incorporate manual adjustment. The rear seats of the Z/28 have also been modified for weight reduction. Nine pounds, or four kilograms, were saved by eliminating the seat-back pass-through, as well as using high-density foam in place of the rigid structure of the seat back and steel mesh of the seat bottom. Additional examples of weight savings include: Elimination of the tire-inflator kit, except for Rhode Island and New Hampshire, where it is required by law Removal of some interior sound deadener, as well as trunk carpet Use of a smaller, lighter battery Thinner rear-window glass – 3.2 mm vs. the standard 3.5 mm Elimination of high-intensity discharge, or HID, headlamps and fog lights No air conditioning except as part of the single option package. The Camaro Z/28 will be available to order in late January with the first cars delivered to customers in the spring. Rights to the first Camaro Z/28, VIN 0001, will be auctioned at Barrett Jackson Auction in Scottsdale, Ariz. on January 18. The Z/28's suggested retail price includes destination and freight charges, as well as the gas-guzzler tax. View full article

  5. By William Maley Staff Writer - CheersandGears.com March 27, 2013 Today at the New York Auto Show, Chevrolet introduced the new 2014 Camaro which features a narrower front end and revised rear end styling. These design changes add up to better aerodynamics and cooling. You still have the 3.6L V6 as the base engine, followed by the 6.2L V8 and the LSA supercharged V8. However, the star of the 2014 Camaro lineup is the new 2014 Camaro Z/28 which is the most track capable Camaro ever built. "We set out to make the fastest road-racing Camaro possible that was still street-legal. While the Camaro ZL1 offers exceptional performance on the street, the drag strip, and the track, the Z/28 is entirely focused on the track performance. The Z/28 will be too track-focused for most drivers, but offers road-racers one of the most capable track cars ever offered from an automaker,” said Camaro chief enginner, Al Oppenheiser. The heart of the Z/28 is the 7.0L LS7 V8 engine. Chevrolet isn't revealing the official figures, only saying only that the Z/28 will deliver "at least 500 horsepower and 470 pound-feet of torque". A six-speed manual is the sole transmission. Other mechanical changes include a limited-slip differential, spool-valve dampers, stiffer springs, and Brembo carbon ceramic discs. The Camaro Z/28 has also gone through a comprehensive diet, losing 300 pounds when compared to the ZL1. The diet included thinner rear glass, lighter wheels, smaller battery, removing the tire-inflator kit and sound-deadening material, and making air conditioning an option. Outside, the Z/28 has a massive front splitter tied to a lift-curbing undertray to help with aero. Out back, a unique spoiler and diffuser help keep the Z/28 on the ground while at high speed. Inside, the Z/28 comes with a matte-metallic finish trim named Octane, flat-bottomed steering wheel, and standard Recaro seats with microfiber suede inserts. One surprise in the Z/28 was the inclusion of a back seat. Chevrolet has modified it by eliminating the pass-through and using high-density foam. The new 2014 Camaro arrives at dealers later this summer. The Z/28 comes out sometime in 2014. Source: Chevrolet William Maley is a staff writer for Cheers & Gears.

Press Release is on Page 2 2014 Camaro Z/28 the Most Track-capable Camaro Ever 2013-03-27 NEW YORK – Chevrolet today introduced the restyled 2014 Camaro line at the New York Auto Show, including the return of the Z/28, the most iconic model in Camaro history. The 2014 Camaro models feature a revised exterior design that integrates high-performance aerodynamics for more efficient cooling and stability at high speeds. The new Camaro Z/28 also features a full aerodynamics package that creates downforce at speed, which helps make it the most track-capable offering in Camaro's history. "As the ultimate track-capable Camaro, this car restores the mission of the original Z/28, and serves as a testament to the expertise of Chevrolet as the best-selling brand of performance cars," said Mark Reuss, president, GM North America. "The build sheet is the wish list of any racer: lightweight, high-revving, dry-sump LS7 engine; carbon-ceramic brakes; integrated coolers for track use; true aerodynamic downforce, and a significant reduction in curb weight. This car could only come from Chevrolet, and could only be called the Z/28." The first Camaro Z/28 was introduced in 1967, created to compete in the Sports Car Club of America's Trans-Am 2 class. It featured a smaller, lighter, 302-cubic-inch V-8 for improved weight balance, as well as quick-ratio steering and a heavy-duty suspension for track use. In keeping with its road-racing focus, the 1967 Camaro Z/28 was not available with an automatic transmission or air conditioning. While the new Camaro Z/28 is not intended to compete in a specific race series, it is solely focused on track capability. In initial testing, the Camaro Z/28 is three seconds faster per lap than the Camaro ZL1. That extra speed comes from three areas: - Increased grip: The Z/28 is capable of 1.05 g in cornering acceleration, due to comprehensive chassis revisions - Increased stopping power: the Z/28 features Brembo carbon-ceramic brakes capable of 1.5 g in deceleration, and consistent brake feel, lap after lap - Reduced curb weight: The naturally aspirated Z/28 weighs 300 pounds less than the supercharged Camaro ZL1, with changes ranging from lightweight wheels to thinner rear-window glass - Like the original, the 2014 Camaro Z/28 is offered only with a manual transmission. In a nod to modern convenience, air-conditioning is available, but only as an option. "We set out to make the fastest road-racing Camaro possible that was still street-legal," said Al Oppenheiser, Camaro chief engineer. "While the Camaro ZL1 offers exceptional performance on the street, the drag strip, and the track, the Z/28 is entirely focused on the track performance. The Z/28 will be too track-focused for most drivers, but offers road-racers one of the most capable track cars ever offered from an automaker." The new 2014 Camaro line will arrive at Chevrolet dealers later in 2013. The Camaro Z/28 is expected to be appearing at track events across the United States in spring 2014. High-performance aerodynamics highlight changes for 2014 Camaro The 2014 Camaro represents the most significant redesign since the introduction of the fifth-generation Camaro as a concept car in 2006. "The 2014 Camaro is our opportunity to apply what we have learned listening to our customers, and our continuing development of high-performance models," said Tom Peters, Camaro exterior design director. "We look for solutions that are both functional and beautiful so that the result is genuine Chevrolet – simple, powerful, honest, and more than expected." Compared to the previous model, the design represents a strong visual change front and rear, resulting in a wider, lower, more contemporary appearance. The front fascia features a wider lower opening, and a narrower upper opening that also updates the appearance of the iconic "halo ring" HID headlamps on the Camaro RS package. The functional hood vent on the Camaro SS helps reduce heat and aerodynamic lift. Moving to the rear, the sculptural decklid, horizontal lamps and diffuser complete the powerful statement. The Camaro Z/28 also features a full aerodynamic package designed to produce downforce at track speeds. At the front, the Z/28 features a large splitter, connected to an underbody panel that further reduces lift. In profile, the Z/28 features fender flares over the front and rear wheels, as well as extended rocker panels that contribute to aerodynamic stability. An aggressive rear spoiler and functional diffuser complete the aerodynamic package. On the interior, the Camaro Z/28 features trim in a distinctive, matte-metallic finish named Octane, the ZL1 flat-bottomed steering wheel, and standard Recaro seats with microfiber suede inserts. The new seats (also available on the coupe versions of the SS and ZL1 models), feature aggressive bolsters for high-performance driving, as well as seat cutouts inspired by the five-point harnesses found on racing seats. To save weight, both front seats incorporate manual adjustment. The rear seats of the Z/28 have also been modified for weight reduction. A total of nine pounds (four kilograms) was saved by eliminating the seat-back pass through, as well as using high-density foam in place of the rigid structure of the seat back and steel mesh of the seat bottom. "Unlike the Ford Mustang Boss 302, we felt it was important to keep the 2+2 configuration of the Camaro Z/28 as Chevrolet already has a world-class two-seat sports car in the Corvette," said Oppenheiser. "By modifying the construction of the rear seat, we were able to reduce the overall weight of the Z/28 while still preserving the flexibility of 2+2 seating." 7.0L, LS7 the heart of the Camaro Z/28's track-capable performance Like the original, the new Camaro Z/28 forgoes ultimate horsepower and torque for improved weight balance and track performance. In 1967, the most-powerful engine available in a factory Camaro was a 396 cid V-8 with 375 horsepower. To prepare the Camaro Z/28 for road racing, engineers specified a lighter, 302 cid V-8, officially rated at 290 horsepower. While the 302 was not the choice for drag racers, it proved ideal for sports-car racing. Today, the most-powerful engine offered is the Camaro ZL1's supercharged 6.2L LSA, which delivers 580 horsepower. The heart of the 2014 Camaro Z/28 is the lighter, naturally aspirated 7.0L LS7 first introduced in the Corvette Z06. "The LS7 is ideal for road racing because it delivers amazing performance in a compact, lightweight package," said Jordan Lee, Small Block chief engineer and program manager. "The broad torque curve and high redline of the LS7 mean fewer shifts are required for each lap, while the lightweight design improves the front-to-rear weight balance for better handling." Co-developed with Corvette Racing, the hand-assembled 7.0L (427 cid) V-8 uses a number of high-performance components, including: - Titanium intake valves and connecting rods, and sodium-filled exhaust valves - CNC-ported aluminum cylinder heads - Forged-steel crankshaft and main bearing caps - High-lift camshaft - Hydroformed exhaust headers - 11.0:1 compression ratio, and a 7,000 rpm redline. - 10.5-quart, dry-sump oiling system For the Camaro Z/28, the LS7 features unique induction and exhaust systems, and delivers at least 500 horsepower (373 kW) and 470 lb-ft of torque (637 Nm). The racing-style, cold-air induction system and large K&N air filter provide maximum air flow. The standard dual mode exhaust system and larger-diameter pipes enable improved air flow. By bypassing the mufflers during acceleration, the system increases both the torque and sound generated by the LS7 engine. The Camaro Z/28 is exclusively offered with a Tremec TR6060 manual transmission. The six-speed features close-ratio gearing and 3.91:1 final drive ratio, both optimized for the power characteristics of the LS7. Power is distributed to the rear wheels via a limited-slip differential featuring a helical gear set, rather than traditional clutch packs. The new design enables the driver to apply more power and get through corners faster, by continuously adjusting the torque bias to maximize available traction. The differential works in unison with Chevrolet's proprietary Performance Traction Management system, which allows drivers to adjust the level of throttle and brake intervention to match their capability and driving environment. Unlike some competitors' "track package" offerings, the Camaro Z/28 makes standard all the cooling systems required for track use. This includes the dry-sump oiling system for the LS7, which is connected to an integral liquid-to-liquid cooling system for engine oil. A second liquid-to-liquid system provides cooling for the transmission and differential. This system pumps overcooled transmission fluid to a heat exchanger in the rear differential before traveling to the transmission. This reduces differential temperatures as much as 100 degrees F. Camaro Z/28 chassis delivers 1.05 g in cornering grip The singular focus of the Camaro Z/28 is most evident in the chassis, where the most has been made of every component for track use, from the ultra-high performance tires to race-proven dampers. "We used the very best components in the industry to deliver uncompromised performance, lap after lap," said Mark Stielow, Camaro Z/28 engineering manager. "We made nearly 200 changes to improve the track performance, which cumulatively make the Z/28 capable of 1.05 g in cornering. For perspective, with all other things, equal increasing maximum grip from 1 to 1.05 g can cut up to four seconds per lap." The Camaro Z/28 is the one of the first production cars fitted with race-proven, spool-valve dampers. Compared to a conventional damper that offers only two-way tuning for bump and rebound, a spool-valve damper allows four-way adjustment to precisely tune both bump and rebound settings for high-speed and low-speed wheel motions. The wider tuning range allowed engineers to dramatically increase the damper stiffness on the Camaro Z/28 without a significant change in ride quality. Additional chassis changes include stiffer string rates and suspension bushings for improved cornering response. The Camaro Z/28 features 19-inch diameter wheels and tires, which reduce unsprung weight by 42 pounds (19 kilograms) per car compared to the 20-inch wheels standard on Camaro SS and ZL1. In addition, the smaller diameter wheels lower the center of gravity by 33 millimeters, further improving handling. At all four corners, the lightweight, forged aluminum wheels are wrapped in massive 305/30ZR19 tires. This is the first production application of ultra-high performance Pirelli PZero Trofeo R tires, and believed to be the widest front tire on any production car. To fully exploit the grip of the Pirelli tires, the Camaro Z/28 also features Brembo Carbon Ceramic Matrix™ rotors and fixed, monoblock calipers. The large 394 x 36 mm front rotors are paired with six-piston calipers, while the 390 x 32 mm rear rotors are paired four-piston calipers. Compared to similar-size, two-piece steel rotors, the lightweight carbon discs save 28 pounds (12.5 kilograms) per car. The combination of tire grip and braking power enable the Camaro Z/28 to achieve up to 1.5 g in deceleration. With standard front brake cooling ducts, the Z/28 is also capable of continuous track use unmatched brake feel, lap after lap. "What makes the Z/28 so addictive is it inspires confidence through every section on the track," said Stielow. "The incredible, balanced performance helps you carry much more speed through every corner: the brakes are so good you can adjust your braking points later and later; the grip and suspension damping allows you to carry more speed through the apex; and then the limited slip allows you to make the most of the LS7 as you power out of the corner." Extensive lightweighting saved 300 pounds over the Camaro ZL1 To optimize the track performance of the Camaro Z/28, the engineering team subjected it to an intensive lightweighting program, saving 100 pounds (45 kilograms) compared to the naturally aspirated Camaro SS and 300 pounds (136 kilograms) to the supercharged Camaro ZL1. "We looked at every subsystem for opportunities to save weight," said Oppenheiser. "Our goal was to get rid of everything that didn't make the car faster, and keep only what was required by law. For example, we wanted to eliminate the audio system completely, but we had to keep a single speaker for the seat-belt chime to meet safety requirements." Other examples of weight savings include: Eliminated the tire-inflator kit, except for Rhode Island and New Hampshire, where it is required by law Removed interior sound deadener, and carpeting from the trunk Replaced the standard LN4 battery with a smaller, lightweight, LN3 battery Specified thinner, 3.2-mm glass for the rear window, compared to 3.5-mm glass on the standard Camaro HID headlamps and foglights are not available Air conditioning is only available as a stand-alone option "The team was so fanatical about saving weight, we even stripped the unused wiring out of the harness when we eliminated the fog lights, speakers, and air conditioning," said Oppenheiser. "Every ounce saved contributed to making this the most track-capable Camaro we have ever built, and a worthy successor to the Z/28 name." View full article
  6. By William Maley Staff Writer - CheersandGears.com March 27, 2013 Today at the New York Auto Show, Chevrolet introduced the new 2014 Camaro which features a narrower front end and revised rear end styling. These design changes add up to better aerodynamics and cooling. You still have the 3.6L V6 as the base engine, followed by the 6.2L V8 and the LSA supercharged V8. However, the star of the 2014 Camaro lineup is the new 2014 Camaro Z/28 which is the most track capable Camaro ever built. "We set out to make the fastest road-racing Camaro possible that was still street-legal. While the Camaro ZL1 offers exceptional performance on the street, the drag strip, and the track, the Z/28 is entirely focused on the track performance. The Z/28 will be too track-focused for most drivers, but offers road-racers one of the most capable track cars ever offered from an automaker,” said Camaro chief enginner, Al Oppenheiser. The heart of the Z/28 is the 7.0L LS7 V8 engine. Chevrolet isn't revealing the official figures, only saying only that the Z/28 will deliver "at least 500 horsepower and 470 pound-feet of torque". A six-speed manual is the sole transmission. Other mechanical changes include a limited-slip differential, spool-valve dampers, stiffer springs, and Brembo carbon ceramic discs. The Camaro Z/28 has also gone through a comprehensive diet, losing 300 pounds when compared to the ZL1. The diet included thinner rear glass, lighter wheels, smaller battery, removing the tire-inflator kit and sound-deadening material, and making air conditioning an option. Outside, the Z/28 has a massive front splitter tied to a lift-curbing undertray to help with aero. Out back, a unique spoiler and diffuser help keep the Z/28 on the ground while at high speed. Inside, the Z/28 comes with a matte-metallic finish trim named Octane, flat-bottomed steering wheel, and standard Recaro seats with microfiber suede inserts. One surprise in the Z/28 was the inclusion of a back seat. Chevrolet has modified it by eliminating the pass-through and using high-density foam. The new 2014 Camaro arrives at dealers later this summer. The Z/28 comes out sometime in 2014. Source: Chevrolet William Maley is a staff writer for Cheers & Gears.

Press Release is on Page 2 2014 Camaro Z/28 the Most Track-capable Camaro Ever 2013-03-27 NEW YORK – Chevrolet today introduced the restyled 2014 Camaro line at the New York Auto Show, including the return of the Z/28, the most iconic model in Camaro history. The 2014 Camaro models feature a revised exterior design that integrates high-performance aerodynamics for more efficient cooling and stability at high speeds. The new Camaro Z/28 also features a full aerodynamics package that creates downforce at speed, which helps make it the most track-capable offering in Camaro's history. "As the ultimate track-capable Camaro, this car restores the mission of the original Z/28, and serves as a testament to the expertise of Chevrolet as the best-selling brand of performance cars," said Mark Reuss, president, GM North America. "The build sheet is the wish list of any racer: lightweight, high-revving, dry-sump LS7 engine; carbon-ceramic brakes; integrated coolers for track use; true aerodynamic downforce, and a significant reduction in curb weight. This car could only come from Chevrolet, and could only be called the Z/28." The first Camaro Z/28 was introduced in 1967, created to compete in the Sports Car Club of America's Trans-Am 2 class. It featured a smaller, lighter, 302-cubic-inch V-8 for improved weight balance, as well as quick-ratio steering and a heavy-duty suspension for track use. In keeping with its road-racing focus, the 1967 Camaro Z/28 was not available with an automatic transmission or air conditioning. While the new Camaro Z/28 is not intended to compete in a specific race series, it is solely focused on track capability. In initial testing, the Camaro Z/28 is three seconds faster per lap than the Camaro ZL1. That extra speed comes from three areas: - Increased grip: The Z/28 is capable of 1.05 g in cornering acceleration, due to comprehensive chassis revisions - Increased stopping power: the Z/28 features Brembo carbon-ceramic brakes capable of 1.5 g in deceleration, and consistent brake feel, lap after lap - Reduced curb weight: The naturally aspirated Z/28 weighs 300 pounds less than the supercharged Camaro ZL1, with changes ranging from lightweight wheels to thinner rear-window glass - Like the original, the 2014 Camaro Z/28 is offered only with a manual transmission. In a nod to modern convenience, air-conditioning is available, but only as an option. "We set out to make the fastest road-racing Camaro possible that was still street-legal," said Al Oppenheiser, Camaro chief engineer. "While the Camaro ZL1 offers exceptional performance on the street, the drag strip, and the track, the Z/28 is entirely focused on the track performance. The Z/28 will be too track-focused for most drivers, but offers road-racers one of the most capable track cars ever offered from an automaker." The new 2014 Camaro line will arrive at Chevrolet dealers later in 2013. The Camaro Z/28 is expected to be appearing at track events across the United States in spring 2014. High-performance aerodynamics highlight changes for 2014 Camaro The 2014 Camaro represents the most significant redesign since the introduction of the fifth-generation Camaro as a concept car in 2006. "The 2014 Camaro is our opportunity to apply what we have learned listening to our customers, and our continuing development of high-performance models," said Tom Peters, Camaro exterior design director. "We look for solutions that are both functional and beautiful so that the result is genuine Chevrolet – simple, powerful, honest, and more than expected." Compared to the previous model, the design represents a strong visual change front and rear, resulting in a wider, lower, more contemporary appearance. The front fascia features a wider lower opening, and a narrower upper opening that also updates the appearance of the iconic "halo ring" HID headlamps on the Camaro RS package. The functional hood vent on the Camaro SS helps reduce heat and aerodynamic lift. Moving to the rear, the sculptural decklid, horizontal lamps and diffuser complete the powerful statement. The Camaro Z/28 also features a full aerodynamic package designed to produce downforce at track speeds. At the front, the Z/28 features a large splitter, connected to an underbody panel that further reduces lift. In profile, the Z/28 features fender flares over the front and rear wheels, as well as extended rocker panels that contribute to aerodynamic stability. An aggressive rear spoiler and functional diffuser complete the aerodynamic package. On the interior, the Camaro Z/28 features trim in a distinctive, matte-metallic finish named Octane, the ZL1 flat-bottomed steering wheel, and standard Recaro seats with microfiber suede inserts. The new seats (also available on the coupe versions of the SS and ZL1 models), feature aggressive bolsters for high-performance driving, as well as seat cutouts inspired by the five-point harnesses found on racing seats. To save weight, both front seats incorporate manual adjustment. The rear seats of the Z/28 have also been modified for weight reduction. A total of nine pounds (four kilograms) was saved by eliminating the seat-back pass through, as well as using high-density foam in place of the rigid structure of the seat back and steel mesh of the seat bottom. "Unlike the Ford Mustang Boss 302, we felt it was important to keep the 2+2 configuration of the Camaro Z/28 as Chevrolet already has a world-class two-seat sports car in the Corvette," said Oppenheiser. "By modifying the construction of the rear seat, we were able to reduce the overall weight of the Z/28 while still preserving the flexibility of 2+2 seating." 7.0L, LS7 the heart of the Camaro Z/28's track-capable performance Like the original, the new Camaro Z/28 forgoes ultimate horsepower and torque for improved weight balance and track performance. In 1967, the most-powerful engine available in a factory Camaro was a 396 cid V-8 with 375 horsepower. To prepare the Camaro Z/28 for road racing, engineers specified a lighter, 302 cid V-8, officially rated at 290 horsepower. While the 302 was not the choice for drag racers, it proved ideal for sports-car racing. Today, the most-powerful engine offered is the Camaro ZL1's supercharged 6.2L LSA, which delivers 580 horsepower. The heart of the 2014 Camaro Z/28 is the lighter, naturally aspirated 7.0L LS7 first introduced in the Corvette Z06. "The LS7 is ideal for road racing because it delivers amazing performance in a compact, lightweight package," said Jordan Lee, Small Block chief engineer and program manager. "The broad torque curve and high redline of the LS7 mean fewer shifts are required for each lap, while the lightweight design improves the front-to-rear weight balance for better handling." Co-developed with Corvette Racing, the hand-assembled 7.0L (427 cid) V-8 uses a number of high-performance components, including: - Titanium intake valves and connecting rods, and sodium-filled exhaust valves - CNC-ported aluminum cylinder heads - Forged-steel crankshaft and main bearing caps - High-lift camshaft - Hydroformed exhaust headers - 11.0:1 compression ratio, and a 7,000 rpm redline. - 10.5-quart, dry-sump oiling system For the Camaro Z/28, the LS7 features unique induction and exhaust systems, and delivers at least 500 horsepower (373 kW) and 470 lb-ft of torque (637 Nm). The racing-style, cold-air induction system and large K&N air filter provide maximum air flow. The standard dual mode exhaust system and larger-diameter pipes enable improved air flow. By bypassing the mufflers during acceleration, the system increases both the torque and sound generated by the LS7 engine. The Camaro Z/28 is exclusively offered with a Tremec TR6060 manual transmission. The six-speed features close-ratio gearing and 3.91:1 final drive ratio, both optimized for the power characteristics of the LS7. Power is distributed to the rear wheels via a limited-slip differential featuring a helical gear set, rather than traditional clutch packs. The new design enables the driver to apply more power and get through corners faster, by continuously adjusting the torque bias to maximize available traction. The differential works in unison with Chevrolet's proprietary Performance Traction Management system, which allows drivers to adjust the level of throttle and brake intervention to match their capability and driving environment. Unlike some competitors' "track package" offerings, the Camaro Z/28 makes standard all the cooling systems required for track use. This includes the dry-sump oiling system for the LS7, which is connected to an integral liquid-to-liquid cooling system for engine oil. A second liquid-to-liquid system provides cooling for the transmission and differential. This system pumps overcooled transmission fluid to a heat exchanger in the rear differential before traveling to the transmission. This reduces differential temperatures as much as 100 degrees F. Camaro Z/28 chassis delivers 1.05 g in cornering grip The singular focus of the Camaro Z/28 is most evident in the chassis, where the most has been made of every component for track use, from the ultra-high performance tires to race-proven dampers. "We used the very best components in the industry to deliver uncompromised performance, lap after lap," said Mark Stielow, Camaro Z/28 engineering manager. "We made nearly 200 changes to improve the track performance, which cumulatively make the Z/28 capable of 1.05 g in cornering.
