:: Pratt & Miller Chevrolet Corvette C6RS Additional Information :: |
(From
Pratt & Miller Press Release) 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™ (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."
Founded in 1989 by Gary Pratt and Jim Miller, Pratt & Miller
Engineering & Fabrication provides
automotive and non-automotive
clients with leading-edge engineering and low-volume
manufacturing
solutions. For more information, visit the Pratt & Miller website

(From General Motors Press Release) GREEN AND MEAN: JAY LENO’S
E85-CAPABLE Z06-INSPIRED
C6RS CORVETTE BOASTS 600 HP AND
ALTERNATIVE-FUEL CAPABILITY
LAS VEGAS – “Tonight Show” host Jay Leno’s predilection for
performance cars is no secret, but
many fellow enthusiasts may not
know that he is keenly interested in alternative fuels. To prove
that red-blooded power mixes easily with a touch of green, Leno
partnered with Pratt & Miller
the engineering company that
builds and campaigns C6.R Corvettes – to develop a modified
Corvette Z06 that is capable of running on E85 ethanol. It was
unveiled at the 2007 SEMA Show.
More than merely a conversion of the stock LS7 engine to E85
capability, Leno’s alternative-fuel
supercar is powered by a
custom, 8.2L (500-cubic-inch) all-aluminum small-block V-8 that
pumps
out approximately 600 horsepower and 585 lb.-ft. of torque.
“The C6RS is the result of an idea we hatched to prove that
high-performance cars and
alternative fuel technology weren’t
diametrically opposed concepts,” said Leno. “I love the idea of
having 600 horsepower at my disposal, but using a homegrown
alternative to gasoline.”
The engine is built around a custom aluminum cylinder block that
was CNC-milled from a single
block of billet aluminum. And while
the cylinder heads, intake system and dry-sump oiling system
are
stock LS7 components, the engine – which has larger bore and
stroke dimensions than the
7.0L (427-cubic-inch) LS7 – uses a
one-off reciprocating assembly, including a forged steel
crankshaft, forged rods and forged pistons. Katech Engines, the
company that builds engines for
the Corvette C6.R racing program,
developed the engine.
The fuel system and engine control computer were modified to
accommodate E85, and spent
gases exit through a Corsa exhaust
system. Supporting the 600-horse engine’s power is a
blueprinted
and strengthened T-56 six-speed transmission and a
high-performance Centerforce
dual-friction clutch.
C6.R inspiration
On the outside, Leno’s bad and black C6RS emulates the styling of
C6.R racecars, with wider
front and rear fenders and a wider rear
fascia with an integrated spoiler on top and a racing-style
diffuser at the bottom (the diffuser incorporates an LED-lit
backup lamp). A C6.R-style waterfall
hood front fender louvers,
rockers and lower grille opening further define this special
Corvette –
and all of the car’s front-end panels are made of
carbon-fiber, including custom brake air ducts
routed through the
front fenders. With all of its body modifications, Leno’s C6RS is
1.6 inches
wider than stock.
The C6.R’s – and production Corvette’s – aerodynamically styled
bodywork is designed to slice
efficiently through the wind, which
helps enhance fuel mileage.
The race-ready look of the car is enhanced with a quartet of BBS
wheels that feature racing-type
locking center hubs. The forged
aluminum 18-inch front wheels and 19-inch rear wheels ride on
Michelin P295/30ZR18 and P345/30ZR19 tires, respectively.
Adding authenticity to the car’s custom bodywork was the
involvement of Pratt & Miller. The
company took on the task of
crafting Leno’s Corvette into a street-going replica of the
racecars,
which included installing or fabricating a host of
unique components, including:
• A custom DeWitt high-capacity radiator with dual cooling fans
• A carbon-fiber ram-air induction system
• Carbon-fiber inner fender panels that vent hot air from the
engine compartment
• Brembo brakes with six-piston mono-block calipers in front and
four-piston rear calipers
• Dyna-Mat used throughout the cabin and chassis to reduce
interior noise
While the exterior and drivetrain were inspired by the racetrack,
the C6RS’s cabin exudes luxury,
with premium touches and
enhancements from Genuine Corvette Accessories that include a
two-
tone shift knob and boot; leather-covered console armrest,
parking brake handle and boot; an
interior trim kit, racing-style
pedal covers and more.
With its 600 horses on tap and domestically produced E85 fuel in
the tank, Jay Leno’s
alternative-fueled C6RS is an all-American
supercar that proves high performance and
environmental
consciousness go together like the Corvette and checkered flags.
