2008 CORVETTE: ICONIC SPORTS CAR RECIEVES LARGER, MORE POWERFUL LS3 6.2L V-8 AND HOST OF DRIVING, INTERIOR REFINEMENTS

Get comfortable. There's so much new and exciting with the 2008 Corvette that you'll want to grab a hot drink, sidle up to your computer screen and absorb all the details.

The changes involve everything from an all-new, larger and more powerful V-8 engine to refinements in driving characteristics that solidify the Corvette's position as the preeminent American sports car – and further the argument that it is one of the world's best. There are also a host of exterior and interior refinements that raise the Corvette's luxury status and enhance the feeling of craftsmanship.

"Corvette is an uncompromising sports car that rewards its owners with impeccable performance and great comfort," said Ed Peper, Chevrolet general manager. "The changes and enhancements to the 2008 Corvette reflect continual improvements that speak to Chevrolet's unflagging commitment to building the best sports car – and with nearly 55 years of experience, the Corvette just keeps getting better and better."

Also back again for '08 is the 505-horsepower Corvette Z06, an American super car that has won over enthusiasts, journalists and racers around the world for its balance of racetrack-bred performance, daily-driving civility and value.

Here's a look at the new and enhanced features for '08 Corvette models:

Engine – A new, 6.2L LS3 small-block V-8 is the standard engine in Coupe and Convertible models. It is rated at 430 horsepower (321 kW)* and 424 lb.-ft. of torque (586 Nm)* with the standard exhaust system; with the new, optional two-mode exhaust system, power ratings increase to 436 horses / 325 kW and 428 lb.-ft. / 592 Nm. As a result, the standard Corvette is true supercar, capable of 190 mph. The LS3 with the six-speed paddle-shift automatic is the fastest automatic-equipped Corvette ever, with 0-60 mph capability of 4.3 seconds.

This new iteration of the storied small-block family features a revised, larger-bore cylinder block – 4.06-inch / 103.25 mm vs. the previous 6.0L's 4.00-inch / 101.62 mm bores – high-flow, LS7/L92-style cylinder heads; larger-diameter pistons; revised camshaft and camshaft timing; revised valvetrain with offset intake rocker arms; high-flow intake manifold; high-flow fuel injectors from the Z06's LS7 engine; and a new engine beauty cover.

The LS3 features an aluminum cylinder block with cast iron cylinder liners. In addition to its larger bores, which help create a 376-cubic-inch displacement, the block casting also features revisions and machining in the bulkheads that enhance its strength and improved bay to bay breathing. But while the bore of the 6.2L engine is increased when compared with the previous 6.0L engine, the engine's stroke remains at 3.62 inches (92 mm). The pistons for the larger 6.2L engine also are new and are designed for its high-rpm performance capability.

Breathing for the new 6.2L engine is accomplished via new, high-flow cylinder heads. They're based on the large port/large valve design found on the LS7 engine and other GM L92 engines, with larger-capacity, straighter intake ports. The design optimizes intake flow to the combustion chamber and the exhaust ports are also designed for better flow.

Complementing the larger-port design of the heads are commensurately sized valves. The intake valve size alone increases from 2.00 inches (50.8 mm) to 2.16 inches (55 mm) – an increase of nearly 9 percent. The intake valves feature lightweight hollow stems, which enable the engine's 6,600-rpm capability. The exhaust valves also are large, measuring 1.60 inches (40.4 mm) in diameter.

To accommodate the engine's large valves and enable more direct intake port flow, the intake-side rocker arms are offset 6 mm between the valve tip and the push rod. Actuating the valves is a new camshaft, with intake-side lobes providing more than a 5-percent percent in increase in lift, from 0.521-inch to 0.551-inch (13.25 mm to 14 mm). Exhaust-valve lift remains unchanged from the LS2. The camshaft timing was revised to optimize performance with the higher-lift intake cam profile.

Ensuring the cylinder heads receive all the air they can handles falls to a new, acoustically tuned intake manifold. The composite design is manufactured with a "lost core" process that improves runner to runner variation and reduces airflow losses. An acoustic foam material is used to reduce radiated engine noise; it is sandwiched between the outer top of the manifold and an additional "skull cap" acoustic shell. Also new beauty covers atop the engine shield the rocker covers and also feature a noise-reducing, acoustically tuned insert to provide a more refined engine sound.

Exhaust system – Optional on '08 Coupe and Convertible models is a new, two-mode performance exhaust system. Similar in design and function to the system used on the Z06, the dual-mode exhaust uses vacuum-actuated outlet valves, which control engine noise during low-load operation, but open for maximum performance during high-load operation. It is not identical to the Z06 system; the Coupe/Convertible uses a 2.5-inch-diameter exhaust, while the Z06 uses a three-inch system.

With the new, dual-mode performance exhaust, power output for Coupe/Convertible rises from 430 horsepower (321 kW) and 424 lb.-ft. of torque (575 Nm) to 436 horses (325 kW) and 428 lb.-ft. (580 Nm). This system gives the Corvette a more aggressive exhaust sound character that will appeal to performance enthusiasts.

Transmissions and axle ratios – The shifting efforts for both the six-speed manual transmission and paddle-shift six-speed automatic transmissions have been improved in '08 Corvette models. The manual transmission shifting improvements include a more positive and direct feel during gear changes, with better gate-to-gate location.

The six-speed paddle-shift automatic transmission on Coupe and Convertible is improved with new hardware and a new controller calibration that deliver quicker shifts. This change bolsters the feeling of performance and driver control when using the shifting paddles.

Also new for '08 models is the availability of the 2.73 performance axle ratio with the automatic transmission. It is included with the Z51 package.

Steering system – The Corvette's precise rack-and-pinion steering system is revised to provide improved feel at all speeds. The revisions are due to a new, premium machining process of the system's internal components, a new, stiffer intermediate shaft and controller calibration changes.

Wheels – Corvette Coupe and Convertible models come with a new split-spoke wheel design for '08. The design was introduced on the limited-edition '07 Indianapolis 500 Pace Car replicas with a Sterling Silver finish. The standard 18-inch front wheels and 19-inch rear wheels feature a Sparkle Silver finish, with a Competition Gray version optional.

Also new is a distinctive, performance-oriented forged aluminum wheel for Coupe and Convertible. It comes in a polished finish.

Exterior colors – There are two new premium exterior colors available with 2008 Corvette models: Jetstream Blue Metallic Tintcoat and Crystal Red Metallic Tintcoat; they replace Le Mans Blue Metallic and Monterey Red Metallic Tintcoat.

Custom Leather-Wrapped Interior Package – Available on Coupe, Convertible and Z06 models, the new Custom Leather-Wrapped Interior Package offers a stylish, two-tone leather-appointed cabin with details that enhance the feeling of Corvette's craftsmanship. Details include:

* Two-tone, leather-wrapped upper and lower instrument panel, door pads and seats
* Choice of new, exclusive colors: Linen or Sienna, with unique color breakup
* Padded door panel armrests
* "Corvette" embroidered on passenger-side dash pad
* Embroidered crossed flags logo on headrests
* Unique center trim plate with Bias pattern.

Interior enhancements – All models feature a new wrapped instrument panel center trim plate, with bright surrounds for the shifter and cupholder. There are also new metal-finish door sill plates that greet passengers as they step into the vehicle, as well as a new lighted control knob for the available Magnetic Selective Ride Control.

Feature changes and enhancements – All Corvette models now come standard with features that were previously optional or part of equipment packages. They include:

* OnStar with available Turn-By-Turn Navigation
* XM Satellite Radio
* Auto-dimming rearview mirrors (with compass)
* Audio input jack on all radio systems except navigation; Personal Audio Link is available as a dealer-installed item with the navigation system.

The '08 Corvettes also come with a new Keyless Access fob, which features the key and remote-function controls integrated in a single unit.

Corvette design and interior details

Dramatic fender forms and exposed headlamps combine with the grille to create a strong visual identity for the Corvette, while the tapered rear deck and fascia improve high-speed performance. The lean rear design sports round taillamps and center-exit exhaust. The fixed Xenon high-intensity discharge headlamps provide superior lighting performance. With a 0.286 coefficient of drag, the Coupe models are the most aerodynamic Corvettes ever.

The 2008 Corvette Convertible features a power-operated soft top with the 3LT package; an easy-to-operate manual top is standard. Both configurations use a five-layer fabric that conceals the underlying structure for a good top-up appearance, plus it helps preserve the car's excellent aerodynamics and reduces road noise.

Corvette's interior is inspired by the car's dual-cockpit heritage. High-quality materials, craftsmanship and functionality help deliver premium quality meant to enhance performance driving. The instrument panel and doors are covered with cast-skin foam-in-place trim that looks like a leather-wrapped, padded panel. It is warm and inviting and has double the life of conventional trim materials.

An AM/FM/XM radio with CD player and audio input jack is standard. An optional Bose audio system with an in-dash six-disc changer adds to the choices available to the audiophile owner. Steering-wheel mounted audio controls – introduced in '07 – are included with the Bose premium system.

A full-function OnStar system is standard and an onboard navigation system with voice recognition is available. Using a 6.5-inch (165 mm) color touch-screen display, the DVD-based system contains all the map data for the 48 contiguous states and most of Canada on one disc.

Driving dynamics

Corvette Coupe and Convertible have a hydroformed steel rail backbone structure, which features cored composite floors, an enclosed center tunnel, rear-mounted transmission and aluminum cockpit structure. Suspension cradles, control arms, knuckles, springs, dampers, bushings, stabilizer bars and steering gear have all been redesigned. New Goodyear Extended Mobility Tires (EMT) take advantage of the latest sidewall design and compound technology for run-flat capabilities.

Three suspension choices allow drivers to choose the setup that best suits their driving style. The standard suspension is tuned for a balance of ride comfort and precise handling. Corvette is now more poised at even higher handling levels, yet easier to drive.

The optional Magnetic Selective Ride Control suspension features magneto-rheological dampers able to detect road surfaces and adjust the damping rates to those surfaces almost instantly for optimal ride control. Cross-dilled brake rotors are included when this feature is selected, allowing customers to combine the larger brakes from the Z51 performance package with the comfort of Magnetic Selective Ride Control.

The Z51 Performance Package brings Coupe and Convertible performance very close to the widely admired previous generation Z06. The Z51 offers more aggressive dampers and springs, larger stabilizer bars, Goodyear Eagle F1 Supercar EMT tires, enhanced cooling and larger cross-drilled brake rotors (13.4 inches / 340 mm in front and 13 inches / 330 mm in rear) for optimum track performance while still providing a comfortable ride.

With each suspension, three standard dynamic chassis control systems – anti-lock braking, traction control and Active Handling – operate in concert. In all, the dynamic chassis control systems are smarter, less intrusive and more adept at making the total driving experience precisely what drivers have come to expect from their Corvette.

Corvette Z06 details

As the fastest, most powerful and most technologically advanced production model in Corvette's history, t he Corvette Z06 offers an unprecedented level of capability and technology, making it one of the best performance values on the market.

Design – The Z06 has an unmistakable and aggressive appearance, with design cues that include:

* A wide front fascia with a large, forward-facing grille opening, a splitter along the bottom and wheel opening extensions along the sides to provide aerodynamic downforce
* A cold air scoop in front of the hood that integrates an air inlet system for the engine
* The trailing edge of the front wheel opening is radiused to achieve improved drag, but protects the body finish with a tough molding, and a large air extractor is located behind the wheel
* A fixed-roof body style optimizes body rigidity and mass
* Wider rear fenders with flares cover the massive rear tires and a brake cooling scoop in front of the wheels visually balances the fender extractor
* A tall rear spoiler houses the CHMSL on the top of the rear fascia
* 10-spoke wheels (18-inch, front; 19-inch, rear)
* Four large stainless steel exhaust outlets
* Z06 badging on the carbon fiber front fenders

The aerodynamics of the Z06's exterior were shaped by the experiences of the Corvette racing program, where high-speed stability and cornering capability are paramount. And while the race cars use large rear wings, the Z06's elevated spoiler provides sufficient downforce to balance the road-worthy front splitter without adversely affecting aerodynamic drag. The Z06's Cd is 0.34.

For all its race-inspired functionality, the Z06 is designed to be a daily-driveable high-performance vehicle. To that end, comfort and convenience are held to a very high standard. High-Intensity Discharge lighting, fog lamps, leather seating, dual-zone air conditioning, cabin air filtration and head-up display (HUD) with track mode and g-meter are standard.

The Z06 gauge cluster displays the Z06 logo on the 7000-redline tachometer and has a readout on the oil pressure gauge to reflect the higher standard pressure of the dry-sump oiling system. The seats feature two-tone leather surfaces, with Z06-logo embroidery and contrasting stitching.

Z06 options include a Bose audio system with an in-dash six-CD changer, polished, Competition Gray or chrome wheels, a telescoping steering wheel, heated seats, side-impact air bags, a navigation system with GPS and universal home remote.

LS7 engine – The Z06's LS7 7.0L engine delivers 505 horsepower (377 kW) in a 3,132-pound (1,421 kg) package – a combination that delivers 0-60 performance of 3.7 seconds in first gear, quarter-mile times of 11.7 seconds at 125 mph and a top speed of 198 mph (as recorded on Germany's Autobahn). It also provides maximum lateral acceleration of 1.04 g and 60-0 braking in 111.3 feet; it also circuited Germany 's famed N ü rburgring in a time of 7:43 .

The LS7 reintroduced the 427-cubic-inch engine to the Corvette lineup. It is easily identified under the hood by red engine covers with black lettering. The LS7 shares the same basic Gen IV V-8 architecture as the Corvette's 6.0-liter LS2, but it uses a different cylinder block casting with pressed-in steel cylinder liners to accommodate the engine's larger diameter, 4.125-inch (104.8 mm) cylinder bores.

Internally, the LS7's reciprocating components make use of racing-derived lightweight technology, including titanium connecting rods and intake valves, to help boost horsepower and rpm capability. The rpm fuel shut-off limit is 7,100 rpm. The LS7's details include:

* Dry-sump oiling system
* Unique cylinder block casting with large, 104.8-mm bores and pressed-in cylinder liners
* Forged steel main bearing caps
* Forged steel crankshaft
* Titanium connecting rods with 101.6-mm stroke
* Cast aluminum flat-top pistons
* 11.0:1 compression
* High-lift camshaft
* Racing-derived CNC-ported aluminum cylinder heads with titanium intake valves and sodium-filled exhaust valves
* Low-restriction air intake system
* Hydroformed exhaust headers with unique "quad flow" collector flanges.

One of the clearest examples of the LS7's race-bred technology is its use of titanium connecting rods. They weigh just 464 grams apiece and besides being lightweight, which enhances high-rpm performance and rpm range, titanium makes the rods extremely durable.

The LS7's CNC-ported aluminum cylinder heads are designed to meet the high airflow demands of the engine's 7.0-liter displacement. A hydraulic roller camshaft with 0.588/0.593-inch valve lift is used to allow plenty of air to circulate in and out of the engine. To ensure optimal, uninterrupted airflow, the LS7's heads have straight, tunnel-like intake runners. Very large by production-vehicle standards – even racing standards – they are designed to maintain fast airflow velocity, providing excellent torque at low rpm and exhilarating horsepower at high rpm. The heads feature 70-cc combustion chambers that are fed by huge, 56-mm-diameter titanium intake valves. They are complemented by 41-mm sodium-filled exhaust valves.

To accommodate the large valve face diameters, the heads' valve seats are siamesed; and, taken from experience with the engines of C6.R racecars, the LS7's valve angles are held at 12 degrees – vs. 15 degrees for the LS2 – to enhance airflow through the ports.

The LS7 has a dry-sump oiling system designed to keep the engine fully lubricated during the high cornering loads the Corvette Z06 is capable of producing. An engine compartment-mounted 8-quart reservoir delivers oil at a constant pressure to a conventional-style oil pump pick-up at the bottom of the engine. The pressurized oil feed keeps the oil pick-up continually immersed in oil at cornering loads exceeding 1 g.

Oil circulates through the engine and down to the oil pan, where it is sent back to the reservoir via a scavenge pump. The large-capacity reservoir, combined with a high efficiency air-to-oil cooler, provides necessary engine oil cooling under the demands of the engine's power output. With the dry-sump system, oil is added to the engine via the reservoir tank – which includes the oil level dipstick.

Drivetrain – The Corvette Z06's powertrain and drivetrain systems are matched to the LS7's performance capability. The light, four-into-one headers discharge into close-coupled catalytic converters and through two-mode mufflers. The mufflers each feature a vacuum-actuated outlet valve, which controls exhaust noise during low-load operation but opens for maximum power.

At the rear of the LS7 engine, a single-mass flywheel and lightweight, high-capacity clutch channel torque to the rear transaxle. The six-speed manual transmission has been strengthened to handle the LS7's increased torque load. The transmission includes a pump that sends transmission fluid to the front radiator for cooling. Upon its return, the fluid removes additional heat from the differential lube before returning to the transmission. The six-speed transmission connects to a limited-slip differential, with enlarged ring and pinion gears. Stronger axle half-shafts with tougher universal joints transmit power to the rear wheels.

Structure – The Z06 has a unique aluminum body structure for optimum stiffness and light weight for the fixed-roof bodystyle. Perimeter rails are one-piece hydroformed aluminum members featuring cast suspension nodes, which replace many welded steel components on other Corvette models. Other castings, stampings and extrusions are combined into the innovative structure with state-of-the-art manufacturing technologies.

Advanced structural composites featuring carbon fiber are bonded to the aluminum structure. The wider front wheelhouses, for example, are carbon composites and the passenger compartment floors combine carbon-fiber skins with an ultra-lightweight balsa wood core.

The Z06 has a new magnesium cradle that serves as the attachment point for the engine and some front suspension components. Magnesium is lighter than aluminum yet incredibly strong. The magnesium cradle helps improve the front-to-rear weight distribution, as do carbon-fiber front fenders and wheelhouses. Engineers also moved the battery from underhood to a position in the rear cargo area, behind one of the rear wheels.

The mass reductions are offset by some added performance enablers, including dry-sump lubrication, exhaust system with outlet valves, larger wheels and tires, larger brakes and larger roll stabilizers.

Suspension and brakes – The Z06 retains the 105.7-inch (2686-mm) wheelbase of other Corvette models, as well as the short-long arm suspension and transverse leaf spring design, but it rides on all-new wheels, tires, brakes, as well as its own rear spring and roll stabilizer.

The firmer suspension works harmoniously with large 18 x 9.5-inch cast-spun aluminum wheels and 275/35ZR18 tires in the front, and 19 x 12-inch cast-spun aluminum wheels with 325/30ZR19 tires in the rear – the largest wheel-and-tire combination ever offered on a Corvette. The tires use the latest extended-mobility technology from Goodyear to provide a satisfactory ride, but still allow the vehicle to achieve lateral acceleration of more than 1 g. The extended-mobility tires eliminate the need – and weight – for a spare tire and jack or inflator kit, while also reducing the chance of a sudden loss of handling capability.

Complementing the suspension system and large rolling stock is an equally capable four-wheel disc brake system, consisting of 14-inch (355 mm) vented and cross-drilled front rotors and 13.4-inch (340 mm) vented and cross-drilled rear rotors.

The front rotors are acted upon by large, red-painted six-piston calipers that use six individual brake pads. Individual brake pads are used because they deliver more equalized wear compared to what would otherwise be a pair of very long single-piece pads. For the rear brakes, four-piston calipers with four individual brake pads are used. A Delphi four-channel ABS system is standard, as is a very competent active handling system – complete with a Competitive Driving mode.

You've waited long enough to hear the real deal on the 2009 Chevrolet Corvette ZR1, right? The nonstop, server-frying deluge of speculation, hoaxes, misinformation, wild-ass guessing and publicity-stunt silliness has dragged on just short of three years now.

In anticipation of the ZR1's introduction at the 2008 Detroit auto show in January, Chevrolet at last has opened the proverbial hood on this, the most powerful, most expensive and most highly anticipated Corvette in the model's half-century history.

Here, finally, is the real story.

"Greater Than 620 Horsepower"
All right, so there's one thing that we can't put a final figure to and that's the important one: the ZR1's power output.

But Ron Meegan, the assistant chief engineer for the new 2009 Chevrolet Corvette ZR1's supercharged V8 (and formerly a member of the original ZR-1's engine team from 1990-'95), says he expects that once the new car's supercharged 6.2-liter V8 is certified, it will produce "greater than 620 horsepower at 6,500 rpm and 595 pound-feet of torque in the 3,600-to-4,000-rpm range, depending on some last-minute tuning items."

So even GM doesn't have a final power figure yet. Although you can be sure that if Meegan's superiors allowed him to mention any figure to us, they're not worried about making those numbers. Remember, when the current-generation Z06 was unveiled, it came with a claim of 500 hp, and when the production car arrived it had a rating of 505 hp.

Whether the ZR1 is rated at 625 hp or 633 hp or whatever, it won't just be the most powerful Corvette production vehicle ever (including ones measured by the grossly overstated "SAE gross" figures of pre-1972), it won't even be close. The power produced by the ZR1's LS9 engine will be roughly the equivalent of three 1980s-era Corvette small-block V8s bolted together. It'll produce more power than the Corvette C6.R that races at the 24 Hours of Le Mans.

The Nordschleife on Chrome Rims, Y'all
ZR1 chief engineer Tadge Juechter says, "If a buyer really wants them, he can get chrome wheels on it," although he's letting us know that he would never do such a thing and he thinks you shouldn't either. But the ZR1 isn't a racecar.

Think of the Corvette lineup in Porsche 911 terms. The base coupe and convertible Corvette are analogous to the standard Carrera and Carrera S. The Z06 is the GT3 — the loud, hard-core choice of the performance junkie. The ZR1 is the Porsche Turbo. It's devastatingly fast, but it's also intended to be civilized. It's available with a head-up instrument display, power-adjustable seats, high-end audio and Delphi's smooth-riding MagneRide suspension dampers. It's no raw-boned racer. Hell, at 3,300 to 3,400 pounds, the ZR1 is almost 300 pounds heavier than a Z06.

Juechter adds, "It's sort of like the Turbo but for less money and with performance — more like the Carrera GT."

That's big talk. But, while Chevrolet is not yet making specific performance claims, Juechter notes that the ZR1 will be faster, quicker and more responsive in every way than a Z06. "You won't see a huge difference in 0-60 mph because even the Z06 is traction-limited through most of that," he says. "But in the quarter-mile and tests from zero to 100 mph to zero, there will be big differences."

And just to up the ZR1's chest-puffing quotient, Juechter notes this car "will be able to take the production-car track record at any racetrack." Ex-squeeze me? And no, the company has not done an officially timed run at the Nürburgring yet.

As for top speed, Juechter says only that the 200-mph speedometer of the standard and Z06 Corvettes has been replaced with a 220-mph unit, because the standard one is "grossly inadequate."

Hot Wheels
By now you probably have noticed that the ZR1 looks like, well, a C6 Corvette. The silhouette is, of course, the same and the overall dimensions are essentially identical to a Z06.

But there's a goodly helping of racecar bluster applied to this vehicle. It's hard to miss the hole in the hood that measures roughly 19 by 16 inches, for example. A clear polycarbonate window lets you see the intercooler cover with its fancy script. This is the ZR1's signature styling flourish. Truth be told, it's a bit Hot Wheels for our tastes. The hood is made from carbon fiber, and while the exterior has been painted, the underside retains its carbon-fiber's undressed matte finish.

The front fenders with their ZR1-specific twin-port gills are also made from carbon fiber. The prominent aerodynamic front splitter is — you guessed it! — carbon fiber. It sticks out proud of the nose by 4 inches at the edges, making it a dandy place to rest your Hummel figurine collection. Clear-coated carbon rocker extensions make the vehicle look almost subterranean. The top and B-pillar are covered in clear-coated panels of the stuff as well. This car will look wicked in black.

According to Juechter, GM has used a special super-secret additive to the clear coat to protect the unpainted carbon from the sun's ultraviolet rays. (UV rays can break down the resin that helps give carbon fiber its stiffness.) He claims that the substance costs $60,000 per gallon. But since the clearcoat needs only 3 percent of the stuff, the resulting clearcoat costs merely an absurd $2,000 per gallon. This mystery material was originally designed to protect circuit boards from UV. Juechter acknowledges only that the substance has no chemical similarity to mayonnaise and says, "We should probably not imply that it is edible anyway."

The front aero splitter is matched in the rear by a spoiler of a relatively modest height that is taller at the edges than in the center, a measure to combine an optimum balance between a decrease in aerodynamic lift and an increase in aerodynamic drag.

The wheels are a new design produced by Speedline, measuring 20-by-12 inches in the rear and 19-by-10 inches up front. They are covered (barely) by Michelin Pilot Sport PS2 tires, specifically formulated for this vehicle. At 335/R2520, the rear tires resemble something you might find in a steamroller; the fronts are a not-much-more-modest 285/R3019.

The interior is essentially identical to the regular Corvette. ZR1 badging and a boost gauge in place of the voltmeter are the only changes to the cabin.

Traction Limited
Even with the gigantic meats bolted to the backside, the ZR1 will be what is euphemistically called "traction limited." In other words, all that power just goes up into expensive smoke when you try to lay the power down.

And since launching a car with so much horsepower can become a violent, axle-hopping mess, Chevrolet has come up with two novel countermeasures.

First are the rear shocks. When you're stopped and the clutch pedal is depressed and you pile on some revs, the car assumes you want to launch it hard. It automatically softens the compression damping of the rear shocks, and this allows the rear end to squat and effectively shift more weight to the rear of the car for added traction. At the same time, the rebound damping of the rear shocks goes up to 99 percent of full stiffness. This means that the rear cannot spring back up under power in the up-and-down monkey motion of axle hop.

All this is perhaps the cleverest use of adjustable shocks that we've ever heard of. Also, according to Juechter, the standard magnetic shocks allow the ZR1 chassis team to use softer springs than the Z06 for a more compliant ride. To further mitigate power hop, Chevy has also fitted the ZR1 with axle half-shafts of different diameters (33mm on the right and 40mm on the left).

We'll see how all of this works next year when we finally get to drive the thing. We might just try a hard launch or, you know, several.

Stop, I Say
There should be no dispute about the effectiveness of the ZR1's brakes. The rotors are as large as or larger than most wheels were just a decade ago.

In what must be a very sweet moment for a longtime Corvette engineer, Juechter notes that the monster 15-inch Brembo carbon-ceramic rotors fitted as standard to the ZR1's rear wheels are the brakes originally designed for the front of Ferrari's 650-hp Enzo supercar. In the front of the ZR1, you'll find even larger 15.5-inch carbon-ceramic units.

Juechter says, "The only vehicle I know of that has these brakes as standard equipment is the 1,000-hp Bugatti Veyron." Then he adds with a grin, "Although I think you can get them as a $20,000 option on the Ferrari 599." We get the sense Juechter will be using these laugh lines many, many times in the near future.

The Price of Production
Chevrolet isn't about to tell us the price it intends to charge for the 2009 Chevrolet Corvette ZR1. But it tells us that the prime motivator for the project has been GM honcho Rick Wagoner, who asked, "What would a $100,000 Corvette look like?" The ZR1 is apparently the answer and we expect the car's list price will be near enough to the $100,000 mark.

Chevy says it is constrained by production of the carbon-fiber bits to only 2,000 ZR1s per year, and since it seems to us as if we've met almost as many Corvette nuts in our career with the funds to bid up the price significantly, we think the list price might be strictly academic in the first year's production.

So that's it. There's no more mystery Corvette. We'll have to just go ahead and go through the arduous task of driving the thing and testing it.

Shortly thereafter we'll begin speculating on the C7 Corvette and the circle of life will continue.

2011 CORVETTE Z06 CARBON LIMITED EDITION
Taking track-to-street technology to a new level

DETROIT -- When the 2006 Corvette Z06 was introduced, it represented the closest connection to the Corvette race cars ever. The 2009 Corvette ZR1 closed the gap between racing and production even further. This year, Corvette continues its tradition of track-to-street technology transfer with the 2011 Corvette Z06 Carbon Limited Edition.

"Designed to further incorporate technology developed through racing, the Corvette Z06 Carbon Limited Edition is a tribute to the 50th anniversary of Corvette's first race in the 24 Hours of LeMans," said Jim Campbell, Chevrolet General Manager. "With a limited production of 500 units, this car is a must-have for the true Corvette collector and driving enthusiast."

The Corvette Z06 Carbon Limited Edition is another example of the expanded Corvette line-up. Five years ago, customers had the choice of a Corvette coupe or convertible. With the addition of the Z06, Grand Sport coupe and convertible and ZR1, Corvette enthusiasts now have more choices than ever.

"For track use, the Z06 Carbon is the best balanced Corvette yet. It combines the lightweight and naturally-aspirated Z06 engine with the road-holding and braking of the ZR1," said Tadge Juechter, Corvette Chief Engineer. "For technical tracks like Laguna Seca, the Z06 Carbon could shave up to three seconds off the Z06 lap time."

This limited edition Z06 will boast Brembo carbon ceramic brakes with specific dark gray metallic calipers. These powerful brakes were first introduced on the ZR1. Black 20-spoke 19-inch front/20-inch rear wheels complement the car's Michelin PS2 tires. Other mechanical features include Magnetic Selective Ride Control for the first time on the Z06 and enhanced cooling. The car also features a special carbon pattern engine cover.

The Corvette Z06 Carbon will be available in two colors: Inferno Orange and the all-new Supersonic Blue. Black headlamps and mirrors, a ZR1-style body color spoiler, body color door handles, carbon fiber raised hood, and black carbon fiber rockers and splitter enhance the Z06's dynamic design and reduce mass and aerodynamic lift. For track events, customers can also install the Euro-styled racing numbers that come with each car.

The Z06 Carbon's ebony leather and suede interior is complemented by blue or orange seat stitching to match the exterior color chosen. Other features include a unique steering wheel emblem, sill plate and logoed headrest. The suede used on the steering wheel, shifter, seat inserts, armrests and doors add to the luxury of this limited edition Z06.

An optional Z07 performance package that includes the mechanical upgrades introduced on the Z06 Carbon can be added to a regular 2011 Z06. This package also includes Competition Gray 20-spoke wheels and all the chassis and cooling upgrades.

The CFZ Z06 carbon fiber package includes black carbon fiber rockers, splitter and roof panel with the full-width body color spoiler. It can also be purchased with or without the Z07 package on regular Z06 models.

The 2011 Corvette Z06 Carbon Limited Edition, as well as the new Z07 and CFZ Z06 option packages will be available in late summer.

2012 Chevrolet Centennial Edition Corvette Celebrates Racing Heritage
Z06 Centennial Edition to be auctioned at Barrett-Jackson Palm Beach sale

DETROIT – Chevrolet, founded by a racing pioneer 100 years ago, celebrates its performance heritage with the 2012 Chevrolet Centennial Edition Corvette, which features a sleek black color scheme, unique design elements and Corvette's trademark sports car technology.

The 2012 Centennial Edition package will be available on all Corvette models – including Grand Sport, Z06 and ZR1 – starting this summer.

The special package was inspired by Chevrolet's racing-bred foundation, which continues with Corvette's international racing excellence and production sports car prominence.

"Racing and performance are the roots of Chevrolet, a tradition carried forward today by Corvette," said Rick Scheidt, vice president of Chevrolet marketing. "The Centennial Edition not only celebrates our 100 years, it once again pushes Corvette forward for a new generation of sports car fans."

Chevrolet will auction a Corvette Z06 Centennial Edition at the Barrett-Jackson collector car auction in West Palm Beach, Fla., on April 9, with the proceeds to benefit the Austin Hatcher Foundation for Pediatric Cancer. It will be the 100th 2012 Corvette off the assembly line, with a vehicle identification number ending in "00100."

The Chevrolet Centennial Edition Corvette expresses racing heritage, but does so with a sleek, modern, even sinister-looking appearance. The Centennial Edition package comes exclusively in Carbon Flash Metallic, with satin-black graphics and unique Centennial Satin Black wheels and red brake calipers. The wheels are constructed of lightweight cast-spun aluminum and include a thin red outline around the perimeter of its surface on the Z06. The wheels are specific to the respective Corvette models, including 18-inch/19-inch for Coupe, Convertible and Grand Sport; and 19-inch/20-inch for Z06 and ZR1.

Magnetic Selective Ride Control, the world's fastest-reacting suspension and a technology advance initiated by Corvette, is included on all Chevrolet Centennial Edition Corvette models.

The Centennial Edition also features special badges that signify Chevrolet's racing history. A graphic logo featuring an iconic image of Louis Chevrolet appears on the B-pillars, the center caps of the wheels, and the center of the steering wheel. The seat headrests also carry an embossed centennial logo.

Aficionados will note one other small detail: The historic crossed flags badge contains a small adaptation, with "100" in place of the traditional fleur-de-lis symbol, only for the Centennial Edition.

The exterior color scheme is reinforced inside the car, with the Ebony leather-wrapped instrument panel and doors complimented by red stitching on the steering wheel, seats, console and shifter. Microfiber suede accents on Centennial Edition seats, steering wheel, shifter and armrests were first used on the 2011 Z06 Carbon Limited Edition.

The Chevrolet Centennial Edition will be available on all Corvette models via order code ZLC. Pricing will be released this summer prior to the start of availability.

"Louis Chevrolet was a fearless racing pioneer who also designed our first car," Scheidt said. "Corvette is a natural fit to honor that legacy, while creating a compelling new package for sports car drivers."
