C7 Corvette Rendering

In a move to shore up public confidence following its stint in bankruptcy court, General Motors on Tuesday unveiled its 2-year product plan for the four core brands: Chevrolet, Cadillac, Buick and GM. Included in the Chevrolet news is that production of the C7 Corvette will start in April 2012 for the 2013 model year. GM also added that the Corvette will maintain the front-engine layout that has defined the sports car for 57 years.

This is great news as earlier estimates had pushed back the C7 through 2014. This also means that the Corvette Team will now have the resources and the corporate edict to move full speed ahead on a new design that could see changes to America’s sports car that include a smaller, lighter body, greater use of advanced weight-saving materials like carbon fiber, aluminum and magnesium and perhaps a smaller engine but one that will still provide the power-to-weight ratio that Corvette owners have become accustomed to. Superchargers for everyone?

At the Birthday Bash earlier this year, Corvette Chief Engineer Tadge Juechter reassured the enthusiast gathering that the team is always thinking about the next generation Corvette and how to make it better. Now that the mid-engine layout has once again been tossed aside, Tadge’s engineering team will have essentially just a couple of years to make these engineering decisions and test them in mules which we could see as early as 2011.

As for the actual design of the car, prior this summer we believed the new C7 will again be more of a transition of the C6 body style. However, the public and Corvette enthusiasts were immediately smitten with the Transformer’s Corvette Stingray Concept introduced earlier this year at the Chicago Auto Show. Perhaps the design team will see that owners would accept more of a radical departure from the looks of the C5/C6.

July 2009 Corvette Sales

by Keith Cornett on August 3, 2009

Corvette sales took a bit of dip last month as GM reported 966 deliveries in the month of July. The 966 units is the lowest since January’s 842 deliveries and was 30% lower than the 1,396 Corvettes sold in June 2009. However, based on July sales of Corvettes in 2007 and 2008, the decline is most probably due to smaller dealer inventories and consumer anticipation for the 2010 model which the factory started building last week.

Corvette Racing: GM to Unveil ALMS GT2 C6.R on Tuesday

Our friends at BadBoyVettes have alerted us to a GM Press conference on Tuesday August 4th at 1pm EST for the introduction of the new ZR1-homologated GT2 Corvette C6.Rs. BBV says the new Corvettes will be sporting a new livery created by the GM Design Center.

We can tell you the Corvettes will be yellow and Jake will be there. Corvette Racing’s Program Manager Doug Fehan confirmed as much back in April while talking about the GT2 Corvettes at the Corvette Museum’s Birthday Day Bash:

“Yellow will be the predominant color. We have a tremendous amount of equity built up in that and its not just here in the United States, its around the world…Photographers love it, magazine publishers love it, art people love it, so when you look at all the ancillary stuff that we are able to achieve by retaining that velocity yellow color, that will be the base color on the car but I can assure you that graphically, they will be very distinguishable in the way they look.”

The Corvette Racing team returns to the ALMS grid this weekend for the Acura Sports Car Challenge at the Mid-Ohio August 6-8th. The two-hour, 45-minute race is scheduled to start at 2:10 p.m. ET on Saturday, August 8. The race will be televised same-day tape-delayed on NBC at 4 p.m. ET.

We are checking with some of the Chevrolet communications people to see if the press conference will be available online. We’ll share any details we learn as well as provide full covereage of the unveiling on Tuesday afternoon. Until then, you can catch up again on some of the GT2 Corvette’s details by watching the Doug Fehan/GT2 Corvette video.

Final 2009 Corvette Production Stats

by Keith Cornett on July 29, 2009

2009 Corvette Production

2009 was a year of highs and lows for Corvette. The high was most definitely the introduction of the Corvette ZR1. With a supercharged 638 horsepower engine, it’s the most powerful production Corvette ever built by GM. The new ZR1 garnered the attention of automotive journalists everywhere who showered the car with awards and accolades. When we talk about the low points, it’s the global automotive recession that resulted in a 52% decline in sales from the 35,310 Corvettes built in 2008 to just 16,956 built in 2009.

The Corvette Coupe remains the best selling model in the Corvette lineup with 8,737 produced (49.4%). For the second year in a row, the Z06 outsold the Convertible albeit with a much smaller margin 3,461 vs 3,342 (20.4% vs 19.7%). Finally, the ZR1 model with its base price slightly north of $100,000 saw 1,415 produced for an 8.3% market share.

Black remains the most popular exterior color with a 21.6% of Corvettes produced. However, the real surprise was Cyber Gray, which was a new color addition to the Corvette lineup in 2009. Cyber Gray was selected on 18.3% of all Corvettes and was the most popular color chosen for the combined Z06/ZR1 model. Victory Red was a solid third with a 13.2% share. Just one Corvette was painted LeMans Blue – the very first Corvette ZR1 built – purchased by Dave Ressler for $1 million at 2008′s Barrett-Jackson auto auction.

2010 Corvette Z06 Details and Pricing Announced

by Keith Cornett on June 18, 2009

2010 Corvette Z06

Once the toast of the town, the Corvette Z06 has recently been overshadowed in the news by its two stable mates, the supercharged 638-hp Corvette ZR1 and the new 2010 Corvette Grand Sport. But that doesn’t mean the Corvette Z06 performance and looks have been diminished in any capacity. Far from it. The 505-hp Corvette Z06 remains one of the best performance values on the market and to make sure the Corvette stays within reach of its target market, GM is only upping the price of the 2010 Z06 by $360 over the 2009 model.

Like the other 2010 Corvettes, new to the Z06 is Launch Control and side airbags. On the 3LZ package, buyers will also get power sport seats and power passenger seats. As for the trim, the Corvette Z06 will be offered in all eight standard Corvette colors including Arctic White, Crystal Red Metallic and the new Torch Red.

One the inside, buyers will be able to select a new Cashmere interior later this year and two new console trims called Orbit and Gunmetal will debut. The cross-flags logo can also be embroidered on the seat headrests.

Pricing for the 2010 Corvette Z06 starts at $75,235 which is an increase of $360 over 2009′s MSRP of $74,875.

Here is the full press release from General Motors on the 2010 Corvette Z06

Corvette Z06 details

With racing-inspired powertrain and suspension features, t he Corvette Z06 delivers exceptional levels of capability and technology, making it one of the best performance values on the market. It has an aluminum frame, with carbon-fiber fenders and door panels, making it the lightest Corvette model available.

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 behind the wheel
  • A fixed-roof body style optimizes body rigidity and mass
  • Wide 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 spider-design 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. 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.

For all of its race-inspired functionality, the Z06 is designed to be a daily-drivable 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.

LS7 engine – The Z06’s LS7 7.0L (427 cubic inches) engine delivers 505 horsepower (377 kW) in a 3,175-pound (1,440 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).

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 body style. Perimeter rails are one-piece hydroformed aluminum members featuring cast suspension nodes, which replace many welded steel components on other Corvette models. 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 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.

Suspension and brakes – The Z06 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 wheels, tires and 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 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.

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. The rear brakes use four-piston calipers with four individual brake pads. A four-channel ABS system is standard, as is a very competent active handling system – complete with a Competitive Driving mode.

*SAE certified.

GM Increases 2010 Corvette ZR1 MSRP by $2,910

by Keith Cornett on June 16, 2009

2010 Corvette ZR1

The cost to own America’s own 638-horsepower supercar just got more expensive. GM recently released prices of all Corvette models to dealers and the 2010 Corvette will now start at $107,830. Add the required $1,700 gas guzzler tax for the Corvette ZR1 and the new out the door price increases to $109,530, an increase of $2,910 over the 2009′s MSRP + gas tax of $106,620.

Although no one likes to see prices increases year to year, we’re not at all surprised as dealers routinely sell the Corvette ZR1 for $10,000 or more over the MSRP. The new price adds a little more profit to GM and well-healed buyers probably won’t balk at the new pricing.

GM has not yet released the Options Package pricing yet, but we expect that to remain in the neighborhood of $10,000 for the 3ZR package. In addition to the Chrome ZR1 wheels, the 2010 Corvette ZR1 will feature a new competition gray wheel which we expect pricing to be similar to the 2009 wheel upgrade price of $2,000. So using 2009′s pricing as the basis for calculating the price of a loaded 2010 Corvette ZR1, expect to pay $121,530.

The 2010 Corvette ZR1 does feature several new enhancements over the current model. New is the Performance Traction Management technology, Launch Control and standard side air bags. A new cashmere interior will be available later this fall and now the Corvette ZR1 can be ordered in any of the Corvette’s standard colors including Torch Red, Arctic White and Crystal Red Metallic.

We spoke with Dave Salvatore of Kerbeck Corvette in Atlantic City about the 2010 Corvette and he thought the new pricing was in line considering the new upgrades coming in 2010. If you’re interested in buying one of his three in-bound 2009 ZR1s or ordering a new 2010 model when the factory begins production next month, call him today at 877-537-2325 or visit Kerbeck on the web at: Kerbeck Corvette

Here is the official press releases from Chevrolet about the 2010 Corvette ZR1:

2010 CORVETTE ZR1: PERFORMANCE TRACTION MANAGEMENT ENHANCES AN ALREADY WORLD-BEATING DRIVING EXPERIENCE

After taking on the world’s best supercars and proving a better value and performer by the global automotive press, the Corvette ZR1 returns for 2010 with new Performance Traction Management (PTM) technology. It is an advanced system that is part of a new Launch Control feature, which optimizes traction for greater and more consistent on-track performance.

The PTM system holds a predetermined engine speed while the driver pushes the throttle to the floor. That allows the driver to quickly release the clutch and the system modulates engine torque 100 times per second to maximize the available traction. The system is capable of approaching a skilled driver’s best effort and repeats it consistently.

PTM also integrates the ZR1’s traction control, active handling and selective ride control systems to enhance race track driving consistency and overall performance. When full throttle is applied upon exiting a corner, it automatically manages acceleration dynamics.

The new PTM technology is the newest element that affirms the Corvette ZR1 is an American supercar with the technology and engineering refinement to take on the world’s best – but at a much lower price.

The ZR1’s highlights include:

  • LS9 supercharged 6.2L V-8 rated at 638 horsepower (476 kW), and 604 lb.-ft. of torque (819 Nm)
  • Six-speed, close-ratio, race-proven manual transmission
  • 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 Brembo carbon-ceramic, drilled disc brake rotors – 15.5-inch-diameter (394-mm) in the front and 15-inch-diameter (380-mm) in the rear
  • Blue-painted brake calipers
  • Standard Magnetic Selective Ride Control with track-level suspension
  • Wider, carbon-fiber front fenders with ZR1-specific dual ports
  • 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, visible 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
  • Curb weight of 3,333 pounds (1,512 kg).

The specialized components of the new ZR1 work harmoniously to deliver the most powerful and fastest automobile ever produced by General Motors. It has a top speed of 205 mph (330 km/h).

In addition to PTM, the following features are also new for 2010:

  • Standard launch control
  • Available Torch Red exterior color
  • Available Cashmere interior color
  • Available Competition Gray wheels.

Supercharged LS9 engine

The supercharged LS9 6.2L small-block engine is the power behind the ZR1’s performance. A sixth-generation Eaton supercharger helps the LS9 make big power and torque at lower rpm and carries it in a wide arc to 6,600 rpm, as it pushes enough air to help the engine maintain power through the upper levels of the rpm band – the area where supercharged performance tends to diminish. Heavy-duty and lightweight reciprocating components enable the engine’s confident high-rpm performance.

The Roots-type supercharger uses a unique, four-lobe rotor design. It is augmented with an integrated charge cooling system that reduces inlet air temperature for maximum performance.

The LS9 is hand-assembled at GM’s Performance Build Center in Wixom, Mich., and incorporates special processes typically seen in racing engines to produce a highly refined and precise product. For example, cast iron cylinder liners are inserted in the aluminum block and 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. This ensures a higher degree of accuracy that promotes maximum cylinder head sealing, piston ring fit and overall engine performance.

Transmission and axle

The LS9 engine is backed by an upgraded, stronger six-speed manual transmission and a twin-disc clutch that provide exceptional clamping power, while maintaining an easy clutch pedal 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.

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 allows higher torque capacity with inertia and pedal effort similar to the Corvette Z06. It enables a 25-percent reduction in inertia, thanks to smaller, 260-mm plates; the Corvette Z06’s uses a 290-mm single-disc system.

The rear axle also is stronger in the ZR1 and features asymmetrical axle-shaft diameters – 33 mm on the right side and 40 mm on the left – that were developed after careful testing to provide optimal torque management. The axles are mounted on a more horizontal plane that correlates with the wider width of the rear wheels and tires.

Ride and handling

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

Commensurate with the ZR1’s engine output is the braking system, which is headlined by Brembo 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 . The advantages of these rotors are low mass and resistance to wear and heat. In fact, the rotors should never show corrosion or require replacement for the life of the vehicle, when used in normal driving.

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.

Clamping down on the high-tech rotors are six-piston front calipers and four-piston rear calipers, each painted a ZR1-exclusive blue. The brakes are visible through the ZR1’s exclusive wheels: 20-spoke alloy rims that measure 19 x 10 inches in diameter in the front and 20 x 12 inches in the rear. A Sterling Silver paint finish is standard; chrome and Competition Gray 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

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 a visible carbon-fiber-weave. Visible 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 ports; 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 were developed to enhance high-speed stability and driver control.

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

  • ZR1-logo sill plates
  • ZR1-logo headrest embroidery
  • Specific gauge cluster with “ZR1” logo on the tachometer and a 220-mph (370 km/h) readout on the speedometer
  • Boost gauge added to the instrument cluster and head-up display.

The standard ZR1 (RPO 1ZR) comes with accoutrements based on the Z06, including lightweight seats and lightweight content. The uplevel interior package (RPO 3ZR) includes power-adjustable, heated and leather-trimmed sport seats (embroidered with the ZR1 logo); Bose premium audio system; navigation system; Bluetooth connectivity; power telescoping steering column; custom leather-wrapped interior available in four colors; and more.

By the numbers

In addition to the exterior cues and powertrain, ZR1 models are distinguished from other Corvette models by their vehicle identification number, or VIN. Each carries 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 150th ZR1 built for the model year.
