CORVETTE BOWLING GREEN PLANT

2010-01-08T09:13:00.000-08:00

FACTS

The plant is over one million square feet under roof, or the equivalent of 22 football fields.
The Bowling Green plant assembles more than 35,000 Chevrolet Corvettes and 4,000 Cadillac XLRs per year.
Production each day ranges from 150 - 170 Corvettes and approximately 16 XLRs.
There are 387 suppliers from which the plant receives 1,376 parts. Seventy-seven percent of the car is made in the USA and Canada.
From start to finish, each Corvette spends approximately 36 hours winding seven miles of conveyor systems in the plant.
In the paint department, body panels spend ten hours winding two miles on a conveyor system.
Body panels receive three coats of paint: primer, color and clear coat. Corvette and XLR body panels are composite fiberglass, except for the front and rear bumpers, which are urethane.
The Cadillac XLR is built on a separate line from the Corvette. They share the same frame and both use fiberglass body panels.

HISTORY OF CORVETTE

2010-01-08T06:48:00.000-08:00

There have been six generations of the Corvette produced so far, sometimes referred to as C1 through C6, and various versions with differing features within each generation; the current C6 generation includes the ZR1, which has the most powerful engine used in a production Corvette to date. We look back at the Corvette History on this very website.

1953 Corvette History
The first ever Corvette was built on June 30, 1953 at the Flint, Michigan assembly plant. At the time of its introduction it was America’s only two-seater, and for decades was unchallenged as the premium domestic sports car of its day. These Corvettes were constructed in an area at the back of Chevy’s customer delivery garage on Van Slyke Ave, the first Corvette was designed by Harley Earl and named by Myron Scott after the fast ship of the same name. 300 cars were produced and about 200 are still in the hands of collectors, the 1953 corvettes remain the rarest with the first two cars are missing. By early 1954, Chev said that 315 Corvettes had been built and that production had moved to the assembly plant in St. Louis, Missouri. They predicted that 1000 Corvettes per month would be built in St. Louis by June 1954 and that 10,000 per year could be built and sold. Zora Arkus-Duntov joined Chevrolet Motor Division in 1953 and would become the chief engineer of Corvette.

THE PERSON WHO NAMED THE CAR CORVETTE

2010-01-08T06:43:00.000-08:00

Myron E. "Scottie" Scott, will always be recognized as the man who gave the Corvette, its name.

In 1937, Chevrolet hired him as an assistant director for the Public Relations department, where he was responsible for photography of new cars, designing of press kits, graphics and special events. In 1953, a special executive meeting was arranged to find a name for a new Chevrolet sports car then in the developmental stage. The company wanted a name that began with a "C" and a review of over 300 names began.

None of the 300 names made the cut , then, that night at Scott's home when he searched the C section of the dictionary and stopped at the definition of "corvette" - "a speedy pursuit ship in the British navy". Scott suggested "Corvette" the next day and the group loved it. Myron Scott retired from Chevrolet in 1971. Scottie was inducted into the National Corvette Museum hall of fame.

CORVETTE INSURANCE

2009-09-01T09:37:00.000-07:00

One very important thing to remember when purchasing a Corvette is the Corvette insurance that will also be necessary. Corvette insurance is not a luxury but a necessity. Corvette insurance not only help protects you in case of accident, but vandalism, theft, or if the Corvette is involved in a hit and run. It is important to have Corvette insurance because of the high value of Corvette cars.
To obtain your Corvette insurance, the first step is to contact a Corvette insurance company and discuss the type of insurance you will need and your financial situation with them. A Corvette insurance company will then review your driving history before offering you a Corvette insurance agreement. The Corvette insurance allows you protect or cover a Corvette in exchange for monthly installment payments. If you are involed in an accident, you must contact the Corvette insurance company, so you can get back on the road as soon as possible. Corvette insurance allows you to drive your dream car without worrying about what might happen.
Owning a Corvette, the original American sports car, has been a dream held by many luxury car enthusiasts since Chevrolet began producing them in 1953. From its original roadster attitude to its modern aerodynamic incarnation, the concept of the Corvette has become as part of the American psyche as baseball and apple pie. Sitting behind the wheel of such Corvette classics as a 1958 red and white roadster or the stealth-like Z06 is, to say the least, a dream of every luxury car enthusiast. Obtain Corvette insurance and start driving today!

THINGS TO LOOK OUT WHEN INSURING MY CORVETTE PART 1

2009-09-01T09:36:00.000-07:00

Additional research revealed there are, in fact, two types of stated policies. One is a stated amount policy in which the premium is based on an amount stated by the insured. Losses, however, are still based on the actual cash value (ACV) of the property at the time of loss, but not to exceed the stated amount. To pay the stated amount automatically would create a moral hazard in that policy holders could overvalue their cars, thus making a profit. This is contrary to the basic principle of indemnity which is to restore a person to the position they were in before the loss. (Mr. Flippin contends, however, Nationwide effectively removed the moral hazard by having their agent inspect the car prior to issuing the policy.)

THINGS TO LOOK OUT WHEN INSURING MY CORVETTE PART 2

2009-09-01T09:30:00.000-07:00

The other is a stated value policy, which is a true valued type of policy where both parties agree, in advance, as to the value of the property. In the event of a total loss, the company will pay the full face value of the policy. It turns out this is an Inland Marine type of policy generally used with works of art, boats and other marine equipment. There are a few companies, however, that do offer it as an automobile policy. This difference may be the reason for the wide misconceptions about stated value policies. Mr. Flippin asked eleven different Nationwide agents how the company would settle a stated value policy. None of them corrected him by saying they were actually *stated amount* polices, five of them said the company would pay the full stated amount and five of them did not know. Only one actually knew the company would not pay the stated amount in the event of a total loss. He said he chose not to sell that type of policy because the insured pays an additional premium and receives no additional protection. In fact, the insured receives less protection. The standard indemnity policy pays the ACV at the time of loss with no limit on the company's liability. The stated amount policy still pays the ACV at the time of the loss, but the company's liability is limited to the stated amount. For example: Assume a car has an ACV at the time of loss of $10,000. For an $8,000 stated amount policy, the company would only pay $8,000, where they would pay the full $10,000 under a standard indemnity policy. The insured pays an additional premium for the "privilege" of limiting the insurance company's liability.

2009 CHEVEROLET CORVETTE HATCHBACK

2009-05-27T07:19:00.000-07:00

Often referred to as America's only true sports car, the Chevrolet Corvette is one of the world's best known and longest-running nameplates. Oddly, it had a rather humble beginning, starting life back in 1953 with a straight-6 engine and a two-speed automatic transmission. The first few years saw the fiberglass-bodied two-seater from Chevrolet earn praise for its handling but criticism for its relatively tame performance. (At the time, it was soundly outgunned by a variety of European sports cars in terms of performance.)

Thankfully, a V8 engine option debuted in 1955, and by the late '50s, the Chevy Corvette could hit 60 mph in less than 6 seconds. The intervening decades have seen the Corvette pass through multiple generations. Each decade has brought its own Corvette theme, including the muscle-bound '60s, the highly stylized '70s and the electronically aided '80s. More recently, the Chevrolet Corvette has improved enough in the refinement department that many finally consider it worthy to compete against the world's best.

Highlights of the Corvette's timeline include the '57 Fuelie (the nickname for the optional fuel-injected 283 V8), the '63 Sting Ray split-window coupe, the 1965-'67 big blocks (396 and 427-cubic-inch V8s), the high-revving LT-1s of the early '70s, the ultra-high-performance ZR-1s of the early '90s and the fast yet user-friendly C5s (fifth generation) of the late '90s. Of course today's Corvette, an outright bargain when compared to sports cars from Europe, should be acknowledged as well. The current Corvette offers the performance of an all-out exotic at a third to a quarter of the price

History

2009-05-15T04:53:00.000-07:00

Entering the 1950s, no corporation even came close to General Motors in its size, the scope of its enterprise or its profits. GM was twice the size of the second biggest company in the world — Standard Oil of New Jersey (forefather of today's ExxonMobil), and had a vast conglomeration of businesses ranging from home appliances to providing insurance and building Chevrolets, GMCs, Pontiacs, Oldsmobiles, Buicks, Cadillacs and locomotives. It was so big that it made more than half the cars sold in the United States and the U.S. Department of Justice's antitrust division was threatening to break it up. In the vast 21st century, it's almost hard to imagine how overwhelmingly large GM was back then.

But it didn't make a sports car. The idea of a car coming from stodgy GM that could compete with Jaguar, MG or Triumph was almost absurd.

Still, there was room inside GM for dreams even if there wasn't any room for whimsy. Harley J. Earl, GM's chief designer (formally the head of the Art and Color Section) and the man who invented the "concept car" with the 1938 Buick Y-Job, was in charge of the corporation's ambitious musings. In the fall of 1951, Earl began ruminating about an open sports car that would sell for around the price of a mainstream American sedan — about $2,000. His ideas were rather nebulous, but he handed those notions over to Robert F. McLean, the concept came into focus and a concept car emerged.

While the car was conceived with rigorous attention to the bottom line and production feasibility in mind, it was still only intended to be part of GM's Motorama exhibit at the 1953 New York Auto Show. That is until Ed Cole, Chevy's then recently appointed chief engineer, saw it. Cole, then immersed in development of the world-changing 1955 "small-block" V8, is said to have literally jumped up and down with enthusiasm for the Motorama car. So before it even got to New York, and after some corporate machinations, the engineering to put it into production began.

But first Cole needed to name it. So he called Myron Scott, founder of the All-American Soap Box Derby and an assistant advertising manager for Chevrolet, into a special meeting of executives researching the name. Scott suggested "Corvette," Cole loved it and the rest is history.

Current Chevrolet Corvette

2009-05-15T04:49:00.000-07:00

The latest Chevy Corvette is offered in removable-roof coupe and convertible body styles and in three main trim levels: base Corvette, Z06 and ZR1. The latter two are ultra-high-performance versions that are only available as fixed-roof coupes. The standard Corvette comes with a 6.2-liter, 430-hp V8 coupled to either a six-speed manual or optional six-speed automatic. The Z06 comes with a 505-hp 7.0-liter V8 mated to a six-speed manual. The ZR1 moves the earth with a supercharged 6.2-liter V8 packing 638 hp and running through a six-speed manual.

Equally impressive is the Corvette's daily driver usability. The cockpit boasts friendly ergonomics and comfortable seats. As before, the car's hatchback body style provides massive cargo capacity, which stands at 22 cubic feet in the coupe. A choice of three suspensions (standard, optional Magnetic Ride Control with Sport and Touring modes and track-ready Z51) for the regular Corvette means there's a setup for everyone, and all provide a fairly smooth ride. The Z06 and ZR1, in spite of their immense capabilities, are still docile enough to handle the daily commute without making the driver grit his teeth every time he faces stop-and-go traffic or a rough section of pavement.

In reviews from our editors and posted consumer commentary, the Chevrolet Corvette earns raves for its combination of strong performance, comfortable ride, eye-catching style, affordability and relatively impressive fuel economy. Complaints include the cabin's mediocre cupholder and storage provisions, ho-hum interior materials and the car's lack of nimbleness compared to other competing European sports cars.

Used Chevrolet Corvette Models

2009-05-15T04:41:00.000-07:00

The present-generation (C6) Corvette debuted for 2005 and boasted improvements in performance, build quality and styling compared to the earlier Corvette. A revamped suspension, especially if equipped with the available Magnetic Ride Control, provided both sharp handling and a compliant ride. Design changes included the return to exposed headlamps (first time since '62), crisper fender peaks and a visual slimming of the big rear end. The cabin was upgraded with better materials and the convertible's top could be power-operated. At its debut, it had a 6.0-liter V8 developing 400 hp.

The following year brought the 7.0-liter, 505-hp Z06 model as well as a new six-speed automatic transmission. For 2007, America's sports car received larger brakes (for Magnetic Ride-equipped versions), available two-tone leather interior and a couple of special editions including an Indy Pace Car convertible and the Ron Fellows (a successful Corvette race driver) Z06. More power came about for the base versions in 2008 thanks to the now-current 6.2-liter V8. Chevy also made interior, manual transmission and steering improvements this year.

The previous Chevy Corvette (the C5) was built from 1997-2004 and marked the Corvette's transition from a capable but flawed (in terms of comfort and ergonomics) to world-class sports car. Easier to get in and out of than the C4, the C5 also boasted a new chassis that had nearly 50/50 weight distribution between the front and rear axles, a more compliant suspension, a much roomier cockpit with more supportive seats and a new "LS1" 5.7-liter V8 that made 345 hp. The transmission choices were a six-speed manual and four-speed automatic.

With a 0-60-mph time of fewer than 5 seconds and a top speed of around 175, there wasn't much that could touch this Vette short of a few big-dollar exotics from Europe. That first year saw just the hatchback body, whose styling drew barbs for its rather large hindquarters. But the benefit of the big butt was more than 20 cubic feet of cargo capacity under the rear hatch. A convertible joined the lineup for '98 and the following year brought a fixed-roof coupe. For 2001, the mighty Z06, a reincarnation of an earlier "Z06" performance package from the '60s, debuted, bringing 385 hp to an already impressive chassis. As if that weren't enough, the Z06 gained 20 hp the very next year.

2009 Chevrolet Corvette ZR1

2009-05-05T12:59:00.000-07:00

“Chevrolet’s goal with the new ZR1 is to show what an American supercar can deliver, at a price that trumps exotics that cost two, three or four times as much – and does so with exceptional driveability,” said Ed Peper, Chevrolet general manager.

The ZR1’s basic stats:

All-new LS9 supercharged 6.2L V-8 targeted at producing at least 100 horsepower per liter, or 620 horsepower (462 kW), and approximately 595 lb.-ft. of torque (823 Nm)
Six-speed, close-ratio, race-hardened manual transmission
New, high-capacity dual-disc clutch
Higher-capacity and specific-diameter axle half-shafts; enhanced torque tube
Specific suspension tuning provides more than 1g cornering grip
Twenty-spoke 19-inch front and 20-inch rear wheels
Michelin Pilot Sport 2 tires – P285/30ZR19 in front and P335/25ZR20 in the rear – developed specifically for the ZR1
Standard carbon-ceramic, drilled disc brake rotors – 15.5-inch-diameter (394-mm) in the front and 15-inch-diameter (380-mm) in the rear
Larger brake calipers with substantially increased pad area
Standard Magnetic Selective Ride Control with track-level suspension
Wider, carbon-fiber front fenders with ZR1-specific dual vents
Carbon-fiber hood with a raised, polycarbonate window – offering a view of the intercooler below it
Carbon-fiber roof panel, roof bow, front fascia splitter and rocker moldings with clear-coated, exposed carbon-fiber weave
ZR1-specific full-width rear spoiler with raised outboard sections
Specific gauge cluster with boost gauge (also displayed on the head-up display) and 220-mph (370 km/h) speedometer readout
Only two options: chrome wheels and a “luxury” package

The specialized components of the new ZR1 work harmoniously to deliver the most powerful and fastest automobile ever produced by General Motors. Performance estimates will be announced closer to vehicle’s summer 2008 launch.“Preliminary testing shows the ZR1 builds on the highly respected Corvette Z06 in every performance category, from acceleration and braking, to cornering grip and top speed,” said Peper. “It all boils down to the power-to-weight ratio and the ZR1’s is exceptional . In fact, the ZR1 is expected to be the first production Corvette to achieve a top speed of at least 200 mph.”

Transmission and axle

2009-05-05T12:57:00.000-07:00

The LS9 engine is backed by a new, stronger six-speed manual transmission and a twin-disc clutch that provide exceptional clamping power, while maintaining an easy clutch effort. ZR1-specific gearing in the transmission provides a steep first-gear ratio that helps launch the car, and top speed is achieved in sixth gear – a change from the fifth-gear top-speed run-outs in the manual-transmission Corvette and Corvette Z06.

As the term implies, the twin-disc clutch system employs a pair of discs, which spreads out the engine’s torque load over a wider area. This enables tremendous clamping power when the clutch is engaged, while also helping to dissipate heat better and extend the life of the clutch.The twin-disc clutch system also contributes to the ZR1’s exceptional driving quality, with smooth and easy shifting.

The twin-disc system’s design enables a 25-percent reduction in inertia, thanks to smaller, 260-mm plates, corresponding to a pedal effort that is similar to the Corvette Z06’s 290-mm single-disc system.

The rear axle also is stronger in the ZR1 and features asymmetrical axle-shaft diameters that were developed after careful testing to provide optimal torque management. The axles are also mounted on a more horizontal plane that correlates with the wider width of the rear wheels and tires.

Ride and handling

2009-05-05T12:54:00.000-07:00

The ZR1 is built on the same aluminum-intensive chassis as the Corvette Z06 and features similar independent SLA front and rear suspensions, with aluminum upper and lower control arms. Where the ZR1 differs is the suspension tuning, which was optimized for the car’s steamroller-wide front and rear tires.

Magnetic Selective Ride Control is standard and tuned specifically for the ZR1. The system’s ability to deliver a compliant ride with nearly instantaneous damping adjustments enabled engineers to develop a surprisingly supple ride quality in a supercar that still delivers cornering grip of more than 1g.

From a high-performance perspective, Magnetic Selective Ride Control helps the rear axle remain planted during launch for smooth, hop-free acceleration. It also helps suppress axle movement when cornering on broken or uneven pavement.

Brakes, wheels and tires

2009-05-05T12:51:00.000-07:00

Commensurate with the ZR1’s engine output is the braking system, which is headlined by carbon-ceramic brake rotors. Found on only a few exotics and more expensive supercars, carbon-ceramic brake rotors are made of a carbon-fiber-reinforced ceramic silicon carbide material . Their advantage comes in low mass and resistance to wear and heat. In fact, the rotors should never show any corrosion or require replacement for the life of the vehicle, when used in normal driving.

Clamping down on the high-tech rotors are six-piston front calipers and four-piston rear calipers, each painted a ZR1-exclusive blue. The front pads are equivalent in size to the largest on any production car with a single-pad design – double that of the Corvette Z06’s 70-sq.-cm. front pads.

The brakes are visible through the ZR1’s exclusive wheels: 20-spoke alloy rims that measure 19 inches in diameter in the front and 20 inches in the rear. They come standard with a bright, Sterling Silver paint finish and chrome versions are optional. The wheels are wrapped in Michelin Pilot Sport 2 tires developed specifically for the ZR1, measuring P285/30ZR19 in front and P335/25ZR20 in the rear.

Exclusive exterior

2009-05-05T12:48:00.000-07:00

The ZR1 is instantly recognizable, with perhaps the most identifiable feature a raised, all-carbon-fiber hood that incorporates a clear, polycarbonate window. The window provides a view of the top of the engine’s intercooler, with the legend “LS9 SUPERCHARGED” embossed on the left and right sides, and an engine cover with the Corvette crossed flags logo debossed at the front

The underside of the hood has an exposed carbon-fiber-weave. Exposed carbon-fiber is used on the roof, roof bow, rocker molding and front splitter. These exterior components are protected by a specially developed glossy, UV-resistant clear coat that resists yellowing and wear.Widened, carbon-fiber front fenders with specific, dual lower vents, and a full-width, body-color rear spoiler incorporating the center high-mounted stop lamp, are also unique to the ZR1. All of the exterior features of the car were developed to enhance high-speed stability and driver control.

Interior details

2009-05-05T12:45:00.000-07:00

The ZR1’s interior builds on the brand’s dual-cockpit heritage, with high-quality materials, craftsmanship and functionality that support the premium-quality experience promised by the car’s performance. The ZR1’s cabin differs from the Corvette and Corvette Z06 with the following:

The “base” ZR1 (RPO 1LZ) comes with accoutrements based on the Z06, including lightweight seats and lightweight content. The uplevel interior package includes unique, power-adjustable and leather-trimmed sport seats (embroidered with the ZR1 logo); custom, leather-wrapped interior available in four colors; navigation system, Bluetooth connectivity and more.

By the numbers

2009-05-05T12:42:00.000-07:00

In addition to the exterior cues and powertrain, ZR1 models will be distinguished from other Corvette models by their VIN. Each will carry a unique, identifying VIN digit, as well as a sequential build number. This makes it easy to determine the build number of a specific car – information treasured by enthusiasts and collectors. For example, a ZR1 with a VIN ending in “0150” would indicate it is the 150 th ZR1 built for the model year.

Chassis and Ride

2009-05-05T12:37:00.000-07:00

Its supercharged engine twists out more than 600 horsepower and nearly 600 lb.-ft. of torque. Its racing-inspired dual-disc clutch channels that power to a set of massive, 20-inch by 12-inch rear wheels, helping push the ZR1 to more than 200 mph (320 km/h). It also delivers more than 1g of lateral acceleration and stops with exceptional immediacy.Yet for all its astounding performance attributes, the 2009 Corvette ZR1 has a refined driving experience that makes it a daily-driveable supercar.

The ZR1 is a car anyone can drive confidently and comfortably,” said Tom Wallace, vehicle line executive. “From the very beginning, refinement, balance and compliance were targets that were as important as the car’s maximum performance.

”More than simply scaling wheel, tire and brake sizes to match the powertrain’s output, the ZR1’s engineers harmonized the chassis and suspension components to deliver a driving experience that combines an exceptional ride quality with racing-inspired performance. Enabling elements include standard Magnetic Selective Ride Control and new, Michelin Pilot Sport 2 tires that were developed specifically for the car.

“The ZR1’s handling performance builds on the Z06, but has ride compliance more like the base coupe,” said Tadge Juechter, Corvette chief engineer. “Every element from the stabilizer-bar diameters to the composition of the tires was carefully matched to deliver a balanced driving experience – it’s a supercar that doesn’t sacrifice ride quality for performance.”

Lightweight structure

2009-05-05T12:33:00.000-07:00

The ZR1 has an aluminum structure for optimum stiffness and low mass. It is the same structure used on the Z06, but with specific body panels and drivetrain components mounted to it.The chassis is constructed with perimeter rails made of strong, single-piece hydroformed aluminum members featuring cast suspension nodes. Other castings, stampings and extrusions are combined into the structure with state-of-the-art manufacturing technologies. Advanced structural composites featuring carbon-fiber are bonded to the aluminum structure. The passenger compartment floors, for example, combine carbon-fiber skins with an ultra-lightweight balsa wood core.

Like the Z06, the ZR1 has a magnesium cradle that serves as the attachment point for the engine and some front suspension components, with the new LS9 engine sitting slightly lower in the chassis than the Z06’s LS7 engine. Magnesium is lighter than aluminum yet incredibly strong. The magnesium cradle helps improve the front-to-rear weight distribution, as do the carbon-fiber front fenders, hood and wheelhouses.To optimize the weight balance, the battery is located in the rear cargo area, behind the right rear wheel.

Suspension tuning and Magnetic Selective Ride Control

2009-05-05T12:28:00.000-07:00

The ZR1 retains the 105.7-inch (2,686-mm) wheelbase of other Corvette models, as well as the short-long arm suspension and transverse spring design, but it rides on all-new, wider wheels and tires, stops with carbon-ceramic brakes and features specific spring and stabilizer bar rates – the largest-diameter stabilizer bars available on a Corvette. Also, the axle half-shafts are angled more horizontally to align with the different geometry created by the ZR1’s larger-diameter and wider rear wheels.

Magnetic Selective Ride Control (MSRC) is standard and tuned specifically for the ZR1. It is a real-time damping system that replaces conventional mechanical-valve shocks with electronically controlled shocks filled with a synthetic fluid containing minute iron particles. Under the presence of magnetic charge, the iron particles align to provide damping resistance almost instantly.

MSRC “reads” the road in 1-milisecond intervals (a thousand times per second), making it the world’s fastest-reacting damping system. Its ability to deliver a compliant ride with nearly instantaneous damping adjustments enabled engineers to develop a surprisingly supple ride quality in a supercar that still delivers cornering grip of more than 1g.

“The damping control of MSRC allowed for front and rear springs that have a slightly lower rate than the Z06, which enhances the car’s ride quality,” said Juechter.From a high-performance perspective, Magnetic Selective Ride Control helps the rear axle remain planted during launch for smooth, hop-free acceleration. It also helps suppress axle movement when cornering on broken or uneven pavement.

Carbon-ceramic brakes

2009-05-05T12:24:00.000-07:00

The ZR1 comes standard with carbon-ceramic brake rotors and large-capacity calipers at all for corners. The exotic carbon-ceramic rotors are made of a carbon-fiber-reinforced ceramic silicon carbide material, which offers low mass and exceptional resistance to wear and heat.

The vented and cross-drilled rotors on the ZR1 measure 15.5 inches (394 mm) in diameter in the front and 15 inches (380 mm) in diameter in the rear – making them among the largest carbon-ceramic rotors available on any production vehicle. And while large in size, they are low in mass, saving approximately 11 pounds (5 kg) per corner over comparably sized cast iron rotors.

The rotors are acted upon by six-piston front calipers and four-piston rear calipers, each painted a ZR1-exclusive blue. The front pads are equivalent in size to the largest on any production car with a single-pad design, measuring 148 sq. cm. in surface area – double that of the Corvette Z06’s 70-sq.-cm. front pads.

Michelin Pilot Sport 2 tires

2009-05-05T12:20:00.000-07:00

The ZR1 rides on Michelin Pilot Sport 2 (PS2) tires, measuring P285/30ZR19 in front and P335/25ZR20 in the rear. And while the PS2 tire is familiar with enthusiasts, those on the ZR1 were engineered specifically for the car.

We didn’t merely specify a set of off-the-shelf PS2s for the ZR1,” said Juechter. “Michelin’s engineers worked with GM to develop tires for the car that took into account factors such as the ZR1’s performance goals, expected horsepower, curb weight, weight distribution, aerodynamic downforce, top speed and more. The construction of these tires is unique to the ZR1.”

To save weight, there is no spare tire in the ZR1; the PS2 tires feature Michelin’s ZP technology and can be driven for a short distance with zero pressure until servicing can be attained.

Racing-inspired wheels

2009-05-05T12:17:00.000-07:00

The ZR1 rides on exclusive 20-spoke alloy rims that measure 19 inches by 10 inches in the front and 20 inches by 12 inches in the rear, making them the largest ever offered on a Corvette. Their design was inspired by the multi-spoke racing wheels used on Corvette C6R racecars, which enhance the strength of the wheel at the rim. A bright, Sterling Silver paint finish is standard and a chrome version is optional.

The wheels, while slightly larger in mass than the smaller wheels of the Z06, were developed to be as lightweight as possible, minimizing the ZR1’s unsprung mass.

Design

2009-05-05T12:14:00.000-07:00

In 1990, the Corvette ZR-1 caused a stir with its wider quarter panels, convex rear fascia and squared taillamps. They were the visual clues that identified the special car, enhancing its status as an instant legend.Spotting the ’09 ZR1 at a glance is a snap, too, with its unique, carbon-fiber dual-port fenders, exposed carbon-fiber roof panel, rockers and front splitter, as well as a unique rear spoiler. Also exclusive to the ZR1 is a raised, carbon-fiber hood with a polycarbonate window that provides a view of the supercharged engine’s intercooler that proclaims “LS9 SUPERCHARGED.”

Enthusiasts may consider the ZR1’s hood a crystal-clear glimpse at the soul of the ultimate Corvette.“There is nothing subtle about the ZR1,” said Kirk Bennion, exterior design manager. “It is a car that isn’t shy about its capability.”While the exposed carbon-fiber elements and windowed hood symbolize the car’s character, there are numerous other design details that are less obvious yet no less important to the ZR1’s performance. They include:

Designs detail

Carbon-fiber front fenders widened to accommodate the ZR1’s larger front wheels and tires
ZR1-specific twin vents in the front fenders
Full-width rear spoiler with raised outboard sections incorporates the center high-mounted stop lamp

ZR1-specific 20-spoke alloy wheels in Sterling Silver (chrome available)
Nineteen-inch front wheels and 20-inch rear wheels inspired by C6R racecars
Michelin Pilot Sport 2 tires; P285/30ZR19 in front and P335/25ZR20 in the rear
ZR1-specifc blue-painted brake rotors visible through the wheels

The ZR1 has a performance-driven design,” said Bennion. “There is an aesthetic element to all of the unique features, but they were developed first and foremost to support the car’s performance capability.”Bennion cites the front splitter and rear spoiler as prime examples.

“Because of its top-speed and handling capabilities, the ZR1 requires more downforce than the Z06, and the splitter and rear spoiler were carefully shaped and wind-tunnel tested to meet that requirement,” he said. “The front fenders were widened to cover the wider wheels and their new, twin-outlet vents provide a path for hot air to escape.

”The ZR1 shares the front fascia with the Z06, but the brake-cooling ducts are revised to channel more air to the brakes. Even the front suspension’s A-arms were aerodynamically optimized – they feature air deflectors that direct air to the carbon-ceramic brake rotors.

Exposed carbon-fiber

2009-05-05T11:56:00.000-07:00

A lightweight material pioneered in racing circles, carbon-fiber has an undeniable air of exoticness and only a few production cars have ever employed the relatively expensive composite in their exterior panels. The 2004 Corvette Z06 Commemorative Edition featured a carbon-fiber outer hood and the current Z06 has carbon-fiber fenders and floor panels.

On the ZR1, the roof panel, roof bow, lower rocker moldings, front splitter and the underside of the hood feature exposed-weave carbon-fiber. The other carbon-fiber parts of the ZR1 include the front fenders and hood. The front fascia, doors, rear fenders and rear fascia are made of various other composite materials and all are painted body-color.

The carbon-fiber panels contribute to the car’s visual identity – particularly the exposed-weave panels – but they also serve an important purpose: They save weight. The carbon-fiber roof panel and roof bow, for example, weigh about 7.7 pounds (3.5 kg) less than the already lightweight composite panels on the Corvette Z06.

Ironically, the identifiable and intricate weave pattern of carbon-fiber on most production cars is hidden beneath a shell of paint, because the weave is very susceptible to ultra-violet (UV) light damage, which can cause yellowing or a generally dull appearance. But thanks to a specially developed material that ensures a deep, lustrous and long-lasting finish, the ’09 ZR1’s exposed-weave panels feature a clear coat that protects like paint.

“The clear coat is applied to the exposed carbon-fiber panels that are exposed to sunlight,” said Mark Voss, designing engineer. “In addition to preventing damaging UV rays, the coating has the chip and scratch resistance of conventional paint.”

Powertrain

2009-05-05T11:49:00.000-07:00

Incorporating the engineering experience already found in the Corvette Z06’s LS7 engine and the new-for-2008 6.2L LS3 of the Corvette, GM Powertrain is targeting 100 horsepower per liter for the LS9, or 620 horsepower (462 kW), and approximately 595 lb.-ft. of torque (807 Nm); final SAE-certified power levels will be available in early March 2008.

When you experience the LS9 in the Corvette ZR1, the terms performance and refinement take on a new meaning,” said Tom Stephens, group vice president for GM Powertrain and Quality. “The LS9 demonstrates an outstanding performance range, with smooth driveability at low speeds, and surprisingly fierce performance when the customer wants more power.”

Performance range

2009-05-05T11:45:00.000-07:00

More than just its tremendous peak horsepower and torque numbers, the supercharged LS9 makes big power at lower rpm and carries it in a wide arc to 6,600 rpm. GM Powertrain testing shows the engine makes approximately 300 horsepower (224 kW) at 3,000 rpm and nearly 320 lb.-ft. of torque (434 Nm) at only 1,000 rpm. Torque tops 585 lb.-ft. (793 Nm) at about the 4,000-rpm mark, while horsepower peaks at 6,500 rpm. The engine produces 90 percent of peak torque from 2,600 rpm to 6,000 rpm.Heavy-duty and lightweight reciprocating components enable the engine’s confident high-rpm performance, while the large-displacement Eaton supercharger pushes enough air to help the engine maintain power through the upper levels of the rpm band.

Cylinder block and reciprocating assembly

2009-05-05T11:43:00.000-07:00

The LS9’s aluminum cylinder block features steel, six-bolt main bearing caps, with enlarged vent windows in the second and third bulkheads for enhanced bay to bay breathing. Cast iron cylinder liners – measuring 4.06 inches (103.25 mm) in bore diameter – are inserted in the aluminum block and they are finish-bored and honed with a deck plate installed. The deck plate simulates the pressure and minute dimensional variances applied to the block when the cylinder heads are installed, ensuring a higher degree of accuracy that promotes maximum cylinder head sealing, piston ring fit and overall engine performance.

Nestled inside the cylinder block is a forged steel crankshaft that delivers the LS9’s 3.62-inch (92 mm) stroke. It features a smaller-diameter ignition-triggering reluctor wheel and a nine-bolt flange – the outer face of the crankshaft on which the flywheel is mounted – that provides more clamping strength. Other non-supercharged 6.2L engines, such as the base Corvette’s LS3, have a six-bolt flange. A torsional damper mounted to the front of the crankshaft features a keyway and friction washer, which also is designed to support the engine’s high loads.

Cylinder head details

2009-05-05T11:41:00.000-07:00

The basic cylinder head design of the LS9 is similar to the L92-type head found on the LS3 V-8, but it is cast with a premium A356T6 alloy that is better at handling the heat generated by the supercharged engine – particularly in the bridge area of the cylinder head, between the intake and exhaust valves.In addition to the special aluminum alloy, each head is created with a rotocast method. Also known as spin casting, the process involves pouring the molten alloy into a rotating mold. This makes for more even distribution of the material and virtually eliminates porosity – air bubbles or pockets trapped in the casting – for a stronger finished product.

Camshaft and valvetrain

2009-05-05T11:40:00.000-07:00

The broad power band enabled by the LS9’s large-displacement supercharger allows it to make strong low-end torque and great high-rpm horsepower, which allowed engineers to specify a camshaft with a relatively low lift of 0.555-inch (14.1 mm) for both the intake and exhaust valves. This low-overlap cam has lower lift and slower valve-closing speeds than the Z06’s 505-horsepower (377 kW) LS7, helping the LS9 – with its approximately 620 horsepower – deliver exemplary idle and low-speed driving qualities.The camshaft actuates a valvetrain that includes many components, including the lifters, rocker arms and valve springs, of the LS3 engine. However, LS7 retainers are used to support the engine’s high-rpm performance.

Supercharger and charge cooler details

2009-05-05T11:38:00.000-07:00

The LS9’s R2300 supercharger is a sixth-generation design from Eaton, with a case that is specific to the Corvette application. The supercharger features a new four-lobe rotor design that promotes quieter and more efficient performance, while its large, 2.3-liter displacement ensures adequate air volume at high rpm to support the engine’s high-horsepower aspiration. Maximum boost pressure is 10.5 psi (0.72 bar).

Additional engine details

2009-05-05T11:36:00.000-07:00

Oiling system: The LS9 uses a dry-sump oiling system that is similar in design to the LS7’s system, but features a higher-capacity pump to ensure adequate oil pressure at the higher cornering loads the ZR1 is capable of achieving. An oil-pan mounted oil cooler is integrated, too, along with piston-cooling oil squirters located in the cylinder block. The expanded performance envelope of the Corvette ZR1 required changes to the dry sump system also used in the Z06. System capacity is increased and scavenge performance improved to meet the demands of Chevrolet’s highest-performance sportscar.

Water pump: To compensate for the heavier load generated by the supercharger drive system, an LS9-specific water pump with increased bearing capacity is used.

New six-speed manual transmission

2009-05-05T11:32:00.000-07:00

The Corvette ZR1’s LS9 engine is backed by a Tremec TR6060 six-speed manual transmission, with a twin-disc clutch system. It is based on the new-for-2008 TR6060 six-speed, but upgraded to handle the LS9’s torque output and delivers improved shift quality.The twin-disc clutch system provides exceptional clamping power, while maintaining an easy clutch effort. The system employs a pair of 260-mm discs, which spreads out the engine’s torque load over a wider area, enabling tremendous clamping power to channel the LS9’s torque. It also dissipates heat better and extends the clutch life (in normal driving).Thanks to comparatively small plates, the twin-disc system enables similar disc inertia to the Corvette Z06, which has a 290-mm single-disc system, contributing to low shift effort and providing exceptionally smooth engagement and light pedal effort. In fact, the more powerful ZR1 has a pedal effort similar to the Z06.
