Duntov/Superformance LLC lost no time in turning opportunity into reality, and Duntov immediately began production of the race version of the 1963 Grand Sport, which has already raced and won a number of events this year.

Now the street version of this popular 1960’s muscle car will follow with the series production of a Turn Key Minus chassis by Superformance. The original Grand Sport – intended to be a “Cobra Killer” – was built by General Motors under the watchful eyes of Zora Arkus Duntov, GM’s chief engineer at the time.

The value of a continuation model and that of a historic original is encapsulated in its authenticity. Superformance went to great lengths to ensure that the new street version would be as like the original Grand Sport as two peas are in a pod, having acquired the original blue prints and molds off the original #2 Grand Sport.

With only five originals ever built, the Superformance Grand Sport will give buyers the opportunity to own a piece of GM’s rich history. What makes this street version an even more valuable product is that it is licensed by its originators and that is not only meant to be raced, but is equally at home as a daily driver.

The SPF Grand Sport will be available in a roadster or coupe version and the technical originality is ensured by the legendary discipline and precision that has made Superformance products the leading fully assembled rolling chassis in the world.

Each SPF Grand Sport will be professionally engineered, custom crafted and professionally assembled in the largest and most modern privately owned specialist automotive manufacturing facility in the world.

Based on the Corvette ZR1 supercar, the next-generation Corvette C6.R has even stronger links to the production version of America’s performance icon than its predecessors. The GT2 rules require the use of many production-based components, expanding the opportunities for the two-way transfer of technology between the race track and the showroom. The updated Corvette C6.R utilizes the ZR1’s body design, aerodynamic package, aluminum frame and chassis structure, steering system, windshield, and other components. The race team has prepared the cars for the rigors of endurance racing with safety and performance modifications as permitted by the GT2 rules.

“One of the many benefits of the Corvette Racing program has been the opportunity to demonstrate the technology transfer between the race car and the production car,” said Mark Kent, GM Racing manager. “The global movement toward a single GT class will allow us to compete head-to-head with more marketplace competitors while increasing both the production content of the Corvette C6.R race cars and the relevance of racing to our customers. This is a step that positions Corvette for the future of production-based sports car racing worldwide, and a move that is perfectly aligned with GM’s marketing and business objectives in racing.”

Previous versions of the Corvette C5-R and C6.R race cars have dominated the GTS and GT1 categories in the last decade, winning 77 races and eight consecutive ALMS championships. The GT1 Corvettes were retired following Corvette Racing’s sixth victory in the 24 Hours of Le Mans on June 14, 2009.

“In our decade in GT1, our primary focus has been on racing victories and the validation of the Corvette as a world-class sports car,” said Tadge Juechter, Corvette chief engineer. “As an authentic way to communicate to knowledgeable customers, nothing beats racing. As a cost-effective means to improve vehicle performance, nothing beats racing. These are the reasons racing is in Corvette’s DNA.

“Behind the scenes, the race team and the production car team have grown closer together, finding numerous ways to support each other and to make both cars better,” Juechter said. “Most automotive companies give lip service to claims like ‘racing improves the breed’ or ‘race on Sunday, sell on Monday’. For team Corvette, it is a daily reality. It is now impossible to imagine one team without the other.”

The upcoming GT regulations required a comprehensive redesign of the Corvette C6.R package. In place of the GT1 Corvette’s steel frame, the GT2 version utilizes the production ZR1’s hydroformed aluminum frame as the foundation for a fully integrated tubular steel safety cage. The GT1 version’s wide, louvered fenders are replaced by production-based ZR1 fenders with wheel flares. In accordance with the aerodynamic regulations, the rear wing is reduced 25 percent in width, the diffuser is a flat panel without fences or strakes, and the splitter extends only as far as its production ZR1 counterpart. Steel brake rotors have replaced the carbon discs used previously, and the wheels are aluminum instead of magnesium. The adjustable steering column and steering rack are sourced from the street Corvette.

“Integrating a steel safety cage that meets GM Racing’s stringent standards as well as the strength and durability targets required in racing is a challenge with an aluminum frame,” explained Corvette Racing engineering director Doug Louth. “Working in conjunction with the structure and chassis engineers in the Corvette production group, we designed, built and tested numerous examples before we finalized the configuration. We went through a similar process with the production Corvette group on the body design and aero components. It was truly a collaborative effort between the production engineers and the race team.”

In the remaining races in 2009, the Corvette race cars will be powered by 6.0-liter GM small-block V8s that are based on the 7.0-liter LS7.R that powered the GT1 version. This reduction in displacement was achieved by shortening the crankshaft stroke from 3.875-inch to 3.32-inch. The diameter of the series-mandated intake air restrictors was decreased from 30.6 mm to 28.6 mm, with a corresponding reduction in engine output from 590 to 470 horsepower. A 5.5-liter production-based GM small-block V8 is currently under development and will be introduced at the start of the 2010 season. The Corvette Racing team is continuing its commitment to green racing with the use of E85R ethanol racing fuel.

While much of the hardware has changed, Corvette Racing’s roster of championship-winning drivers remains the same. Johnny O’Connell and Jan Magnussen will share the No. 3 Compuware Corvette C6.R, and Oliver Gavin and Olivier Beretta will drive the No. 4 Compuware Corvette C6. R. They will be joined by Antonio Garcia and Marcel Fassler at Petit Le Mans.

Corvette Racing also has the continued support of its long-time sponsors and technical partners. Compuware is the team’s primary sponsor, with Mobil 1 supplying low-friction lubricants and Michelin providing its world-class racing tires. Corvette Racing’s sponsors also include XM Satellite Radio, UAW-GM, Genuine Corvette Accessories, Bose, Motorola, PRS Guitars, and BBS.

“Compuware leads the world in application performance solutions, and partnering with Corvette Racing gives us another high-tech, high-performance and high-impact platform for communicating to our customers and prospects,” said Compuware Chairman and CEO Peter Karmanos, Jr. “The launch of the Corvette C6.R in GT2 is a great extension to our relationship with General Motors, Chevy and Corvette. We look forward to even more victories in the months ahead.”

The GT2-spec Corvettes were designed, built and tested on a compressed schedule. The program was approved and announced in September 2008, and construction of the first chassis began in early December. The first track test was conducted at Road Atlanta on April 8-9, followed by single-car tests in Elkhart Lake, Wis., and Sebring, Fla.

“The Corvette Racing team had to take on several challenges simultaneously to execute this program,” said Doug Fehan, Corvette Racing program manager. “We were preparing for our regular race season with the GT1 cars while designing the GT2 version. The cars were being built and tested in the midst of our preparations for Le Mans. The team was multi-tasking to the extreme, operating on a leaner budget and a faster timeline. It was a monumental effort to have these cars ready for the Mid-Ohio race.”

Advanced technology tools enabled Corvette Racing to meet the challenge. “With the short development schedule, we relied on ‘virtual’ design and computer simulation more than ever before,” said team manager Gary Pratt. “We made design, engineering and manufacturing simultaneous processes as much as possible. For example, while the first chassis was being built, we continued to run computer simulations on suspension geometry and refined the aerodynamics using CFD (computational fluid dynamics) because these areas didn’t have to be finalized until later in the production timeline. We have developed the capabilities to do finite element analysis and composite fabrication in-house, which has accelerated our design and production cycle.

“We’re not running for a championship this year, so we’re looking at the upcoming races as preparation for 2010,” Pratt said. “Our only testing from this point on will be at the races, and we’ll be doing it in the public eye. Certainly we hope to achieve the same level of success that we did in GT1, but the caliber of the competition we will face in GT2 is very high. When we started in GT1 in 1999, it took a while to win; now we have 10 years of experience that should help us to become competitive in a new category. Everyone at Corvette Racing is looking forward to the challenge.”

Fehan is confident but cautious about Corvette Racing’s prospects in the GT2 category: “In the limited testing we’ve done so far, we’ve been very impressed with the car’s durability, reliability and performance,” he said. “We’ll continue to focus on those three factors in the upcoming races. We view the rest of this year as a development cycle, and we believe that our experience as a team in preparation, race strategy, and pit stop execution should allow us to be competitive even if there is a slight performance disparity.”

The GT2 version of the Corvette C6.R will make its debut in the Acura Sports Car Challenge at the Mid-Ohio Sports Car Course in Lexington, Ohio. The two-hour, 45-minute race is scheduled to start at 3 p.m. EDT on Saturday, August 8. ABC will televise the race tape-delayed at 2:30 p.m. EDT on Sunday, August 9.

Vauxhall’s mighty VXR8 super-saloon gets a potent new V8 engine this summer, with even more power and improved performance. The new unit allows the VXR8 to raise the bar yet again among its rivals, optimising its sophisticated rear-wheel drive chassis still further and retaining its mantle as a driver’s car like no other in its class. New colour and equipment options further enhance this, the fastest car to wear the Griffin badge.

Known as LS3, the new V8 engine’s capacity grows from 5967cc to 6162cc, and thanks to various improvements over the outgoing LS2 unit, such as high-flow cylinder heads, new pistons and an enhanced valvetrain, power is up by 14PS to 431PS at 6000rpm.

This translates to a reduced 0-60mph time for cars with automatic transmissions (down from 5.0 seconds to 4.9) and improved in-gear acceleration for manual models (50-70mph in 3rd gear drops from 2.8 to 2.6 seconds; 30-50mph in 2nd gear drops from 2.0 to 1.9 seconds). And if you fancy smoking your VXR8 at a track day, you’ll see 80-100mph times fall from 4.3 to just 4.0 seconds in 4th gear.

Despite the VXR8’s enhanced performance credentials, its LS3 produces the same emissions and fuel consumption as the outgoing LS2 unit. In addition, the VXR8 automatic receives a transmission oil cooler as standard.

Buyers for the LS3-engined VXR8s also receive the choice of an all-new body colour – Heron White – at no extra cost, as well as the option of factory-fit 20-inch rims for the first time on this model.

Prices for both manual and automatic versions of the LS3-powered VXR8, which are on sale now, rise by £485 to £35,695.

For years the Corvette has been representative of the very embodiment of the quintessential sports car amongst true motorsport fans. Thanks to Corvettes newest models and their successful racing prototypes performing world wide – most notably in the legendary 24 hour race at Le Mans – the Corvette has evolved to rightfully inspire fear in the eyes of supporters of Porsche and Co.

The Corvette C6 ’s acquisition price of almost 75,000 Euro is one trait that is not to be underestimated. Relative to its features and talents it’s a good value for the money. Although it takes a little more than 10,000 Euro on top to attain the status of the fierce Z06, when compared to the Porsche 911 or the Audi R8 the Vette is a true bargain.

GeigerCars, the American car specialists situated in the Bavarian metropolis of Munich present their own Black Edition of the Corvette Z06. Its modification is not flashy nevertheless it embodies very striking customizations. The Z06 is powered by the familiar V8 block engine possessing a phenomenal 7 liters of capacity, 505 horsepower and an impressive torque of max 5638 lb-in (469.8 lb-ft) at 4,800 revolutions per minute. Thanks to Geiger’s own exclusive Tuning Kit the addition of an extra 78 horsepower is mustered up – increasing maximum performance up to an impressive 583 horsepower. The modifications include an exhaust header with high-performance catalytic converters, a stainless steel exhaust system with four 100mm size tailpipes, an airbox incorporating a 100mm size airflow meter. The v8 motor gains considerable fierceness due to the customized throttle valves, a modified intake system, new valve springs, valve heads made of titanium steel and not to mention the installation of a specially designed camshaft.

An overhauled engine management system ensures that the 8 cylinders generate its 583 horsepower performance smoothly. The total price for this impressive Tuning Kit lies at 13.999 Euro. Untypical for an American vehicle, the Geiger Corvette is outfitted with a 6 gear manual transmission, adding only more fun to the overall package. Thanks to a curb weight of only 1.48 tons a level of road performance is attained that would make any Porsche fan go pale in the face.

Driving pleasure is increased significantly by GeigerCars own low rider design with adjustable high performance shock absorbers. In the front, 10×18 black varnish alloy wheels with 275/35 ZR18 tires mediate contact to the road. In the back 12×19 black varnish alloy wheels with 325/30 ZR19 tires perform their task with pride. With so much torque to tame, it isn’t a problem in the least that the back tires won’t always have everything perfectly under control. Quite the contrary, the brake away tail end only prompts a little smile on your face if you’re one of the more trained drivers- besides; the Corvette Black Edition from Geiger also has a front spoiler as well as a modified rear end diffuser.

A legendary brand such as Corvette leaves plenty of traces. Traces which deserve to come under the spotlight. So now fans can order two very special limited edition models: one based on the Corvette Indy 500 pace car, and one as a salute to the unforgettable ‘big-block’ Stingray models from the 60’s.

Corvette Indy 500 Pace Car

For ten years – including the last five years in succession – Corvette has provided the official pace car for the world-famous 500-mile race at Indianapolis (Indy 500). To celebrate this milestone, the manufacturer is building five hundred pace car replicas based on both the C6 Coupe and the Convertible. Only twenty Coupes and five Convertibles are available for Europe, all black with a Titanium Grey interior and equipped with automatic transmission. The Convertible has a gray soft top.

The replicas are immediately identifiable from the striking stickers of the pace car, including the Indy 500 logos. What is special is that each one will carry a signature and serial number by former Indy winner Emerson Fittipaldi. Furthermore, each vehicle is fitted with the new polished five-spoke alloy wheels, a Z06 rear spoiler, a DVD navigation system and the Luxury Package. The latter includes heated seats, head-up display with G-force meter, a Bose® 7-speaker system and an automatically dimming rear-view mirror.

Corvette Z06 427 Limited Edition

The 60’s gave rise to many great memories. One of them is undoubtedly the ‘big-block’ Corvette Stingray. With the introduction of the Corvette 427 Limited Edition Z06, Corvette is also awakening memories – in an exclusive way. It is building 505 of these limited edition vehicles, of which only 52 will be coming to Europe.

The number 427 refers to the cylinder capacity in the American unit of measurement, cubic inches. In the years 1966 to ‘69, the most powerful Corvette engines had this capacity – also the cubic inches equivalent to the 7.0 litre LS7 ‘small block’ in the current Z06.

The special limited edition of the Z06 is characterised by a number of unique 427 styling features, such as the Crystal Red Tintcoat metallic paint with ‘stinger style’ graphics, exclusive chromed rims, a leather interior with embroidered 427 logo on the seats and floor mats, ‘Z06’ inscription in the sill strips, and a centre armrest with serial number and signature by Corvette factory director Wil Cooksey.

Both special models are available for order now, with delivery scheduled for this summer. Please contact your local Corvette dealership for price information.

Powered by a Katech Performance 8.2-liter (500ci) all-aluminum small-block V-8 engine that produces 600 horsepower and 600 lb.-ft. torque, the Pratt & Miller Corvette C6RS employs a purpose-built carbon fiber body to reduce weight and improve aerodynamic efficiency. A computer-controlled adjustable suspension system, center-nut forged aluminum BBS wheels with Michelin tires, and massive Brembo monoblock disc brakes enhance vehicle dynamics. A two-tone leather interior and a comprehensive sound control system produce a quiet, comfortable environment for driver and passenger.

“Our goal was to create a Corvette supercar that delivers an extremely high level of performance with extraordinary comfort and reliability,” said Gary Pratt, co-owner of Pratt & Miller Engineering. “The Corvette C6RS was inspired by our Corvette race program, but it’s not a race car for the street. You can take the Corvette C6RS on a 300-mile road trip, or drive it to a track day and run fast laps.”

Conceived, designed, developed and constructed by the championship-winning Pratt & Miller team, the Corvette C6RS bristles with sophisticated materials and race-inspired technology. The aggressively styled lightweight body, made entirely of carbon fiber, measures 1.6 inches wider than a production Corvette Z06. The carbon fiber front fascia has integrated brake ducts and ram air induction. Aerodynamic enhancements include functional front fender louvers, a carbon fiber underwing and rear diffuser, enlarged front wheel vents and rear brake ducts, an integrated rear spoiler, and a front splitter.

“Every body modification has a purpose,” Pratt explained. “The features were modeled on the C6.R race cars, and there are no nonfunctional styling elements.”

The C6RS chassis is upgraded to complement the improved aerodynamic grip. A Dynamic Ride Height Control suspension system provides three driver-adjustable settings: Low, Drive and High. In the Low mode, the system lowers the ride height to improve handling, while the High setting increases ground clearance to negotiate steep driveways and ramps. The suspension is upgraded with Pratt & Miller-tuned dampers and heavy-duty wheel hubs and bearings.

The same manufacturers who supply tires, wheels, and brakes for the Corvette C6.R race cars also provide the rolling stock for the Pratt & Miller C6RS. The street car’s BBS forged aluminum wheels (18 x 11-inch front, 19 x 13.6-inch rear) have racing-style center nuts. The stunning black chrome wheels are wrapped in Michelin Pilot Sport tires (P295/30-18 front and P345/30-19 rear). The Brembo Grand Tourismo brake system delivers impressive stopping power with six-piston monoblock front calipers with 14-inch rotors and four-piston monoblock rear calipers with 13.5-inch rotors.

With 600 horsepower on tap, the 8.2-liter C6RS engine rivals the performance of the restricted 7.0-liter engines that powered the C6.R race cars to five GT class victories in the 24 Hours of Le Mans and seven consecutive American Le Mans Series championships. Developed by engine partner Katech Performance, the 500ci small-block V-8 is based on a high-strength 6061-T6 billet aluminum Dart block with linerless Nicom-coated 4.205-inch diameter cylinder bores. The rotating assembly features a forged steel crankshaft (4.500-inch stroke), forged 4340 steel connecting rods, and 11:1 compression forged aluminum pistons. The custom-built CORSA stainless steel exhaust system employs the company’s patented Reflective Sound Cancellation™ (RSC) technology to optimize interior and exterior sound quality. An aluminum flywheel and twin-disc clutch transfer the engine’s torque to a blueprinted T56 six-speed transmission.

A luxurious interior is the counterpoint to the Corvette C6RS’s cutting edge technology. A Dynamat sound insulation system produces a quiet refuge, while the instrument panel, doors, console, steering wheel and seats are wrapped in premium quality leather with French seams.

“Our goal with the Corvette C6RS was to capture the soul and spirit of the Corvette C6.R race car in a premium GT car for the street,” said Pratt. “The C6RS is a car with a legendary racing heritage and an unrivalled engineering pedigree. Just as the Corvette C6.R race car has become the benchmark in production-based sports car competition, we believe that the Pratt & Miller Corvette C6RS will set the new standard for sports car performance and luxury on the highway.”
