Time to call in that favor from Santa. Pratt & Miller Engineering will begin taking orders for its Corvette C6RS this December, confirming rumors of a production version after its official debut last week at SEMA. Deliveries of the 600-hp, 600 ft-lbs. monster 'Vette will begin in April next year, as long as you can provide a donor car (C6 coupe, convertible or Z06) and the $185,000 necessary to complete the build.

In addition to the Katech-modified 8.2-liter V8, copious quantities of carbon fiber replace many of the standard components, while 18x11-inch wheels up front and 19x13.6-inch BBS wheels out back cling to the corners of the C6RS, which is a full 1.6-inch wider than a standard Z06.

All the details are available in Pratt & Miller's press release after the jump.

Pratt & Miller Engineering Introduces Corvette C6RS Supercar for the Street
Championship-Winning Race Team Develops the Ultimate Performance Corvette for the Highway

NEW HUDSON, Mich., Oct. 30, 2007 - Pratt & Miller Engineering has designed and developed a new limited edition Corvette C6RS that provides an exceptional level of performance and refinement for enthusiasts. Inspired by the Le Mans-winning Corvette C6.R race cars, the new Pratt & Miller Corvette C6RS supercar combines advanced racing technology with everyday driveability. The first production Corvette C6RS will be available in April 2008.

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(tm) (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."

      I'd never buy it, but I don't see what's so weird about this. Yes, there isn't a huge market for a $250K Corvette, but they're not looking to sell a lot of them anyway.
      • 7 Years Ago
      Once again, why would you pay 1/4 of a million for a Corvette?
        • 7 Years Ago
        Ummm.. Cause you have more money than brains?
      • 7 Years Ago
      This is nice, but what I'm really waiting for is the Pratt and Whitney version.
        • 7 Years Ago
        25,000lbs of thrust...say goodbye to all comers!!!

        lol!

      Enough with the RS badged cars.
      • 7 Years Ago
      so its a $250k corvette?

      ill take the katech street attack z06 if im looking for a superfast vette for under $100k

        You think our government would send young Americans off to die in Iraq for oil and would let China and Cuba drill within our 12 mile limit?

        Unlikely.

        And even if they tried just outside the 12 mile limit, I kind of expect they'd just mysteriously find their drill bits snapping over and over.

        Yes, but you are only using 85% less imported fuel!!! If that is important to you then this is the performance vehicle for you!

        @pete,

        A car like this is hardly going to be a daily commuter, so lifetime volume of fuel consumed is probably going to be quite small, whatever it happens to burn.

        Even so, 85% less domestic fuel is also 85% of fuel that should be used for food. Ethanol fuel is a boon-doggle anyway. it takes about as much energy to grow it, harvest it, process it into alcohol (which is a huge water consumption) and transport it in trucks (too hygroscopic to transport in pipelines) than it gives as fuel energy.

        Gasoline, comparatively has high specific energy, and doesn't offset that with high energy costs to recover and process it. I agree that we shouldn't import as much as we do...

        but that is a matter for congressional WAY-over-regulation and stupid energy policy, rather than a policy of corvette buyers.

        BTW, China, Mexico, and Cuba are cooperating to recover oil just miles off of Key West, FL, where WE CAN'T DRILL, due to US regulation. Environmental impact will probably be the same, if not worse, than if US companies did it, and we still don't have the benefit of domestic oil supplies, out of waters that should be OURS.

        Fix the policies, and one wouldn't have to pay more for ethanol burning cars, or for corn based products that are becoming more scarce from competition with making fuel from foodstuffs. (a monumentally stupid idea in so many ways... There are other crops that have higher sugar content for alcohol production anyway!)

        One more way that histeria rules over common sense and more in-depth knowledge of the subject matter. One more way for the government to stick it's fingers into everything with subsidies and regulations.

        BTW, where in the heck can you buy E85? I live in Iowa. I can see cornfields less than a mile from my house, I can smell it when they harvest, and I have relatives in this state that are corn farmers. And there are Ethanol plants around the area... but I have yet to see a gas station with an E85 pump. A fat lot of good an E85 super-vette will do if you can't fuel up where you live.

      $250,000 Corvette should come with an officially-recognizable certificate of retardation for the buyer.
