    This is it. The speculation, rumors and half-truths can now be set aside -- this is the 2009 Chevrolet Corvette ZR1, officially revealed for all the world to see. Powered by a supercharged LS9 6.2L small-block engine, the ZR1 hasn't even received an official horsepower number from the engineers toiling away at the General. All Harlan Charles, project manager for the Corvette team was able to tell us last week was the new high-powered 'Vette engine is "capable of producing at least 100 horsepower per liter. That's at least 620 horsepower, and approximately 595 lb.-ft. of torque." Chevrolet wasn't even able to give us a time on the 0-60. Charles was only willing to say "it's in the low three seconds." The small-block engine under the hood is only able to hit those massive numbers due to the addition of the positive-displacement Roots-type supercharger with a new, four-lobe rotor design plus an integrated charge cooling system that reduces inlet air temperature for increased performance. That's the "go" end, but the "whoa" end is just as impressive. The ZR1 gets some simply huge carbon-ceramic, drilled disc brake rotors. They're so big and are required to be so powerful they're using the same 15-inch-diameter discs found on the front of a Ferrari 599. Except on the ZR1, they go on the 20" tires in the rear. In the front, they'll be getting even larger 15.5-inch-diameter rotors. Yup, they're simply breathtaking to see up-close. For the time being everyone else will have to check out the gallery below or the full press release after the jump. In case anyone's wondering -- the magazine and website all about the Trend in Motors are the sleazy bunch of d-bags who broke the embargo seven hours early. We just followed suit. We'll have more time to talk about that later -- now go and read the press release and look at the pretty pictures.


    CHEVROLET ENTERS THE WORLD OF SUPERCARS WITH 2009 CORVETTE ZR1
    New, Supercharged LS9 V-8 is the Heart of the ZR1

    DETROIT - Chevrolet officially announced the 2009 Corvette ZR1 - an American supercar that brings the technology and engineering refinement of carbon-fiber, ceramics and electronics together in a distinctive design.

    "Chevrolet's goal with the new ZR1 is to show what an American supercar can deliver, at a price that trumps exotics that cost two, three or four times as much - and does so with exceptional driveability," said Ed Peper, Chevrolet general manager.

    The ZR1's basic stats:

    * All-new LS9 supercharged 6.2L V-8 targeted at producing at least 100 horsepower per liter, or 620 horsepower (462 kW), and approximately 595 lb.-ft. of torque (823 Nm)
    * Six-speed, close-ratio, race-hardened manual transmission
    * New, 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 carbon-ceramic, drilled disc brake rotors - 15.5-inch-diameter (394-mm) in the front and 15-inch-diameter (380-mm) in the rear
    * Larger brake calipers with substantially increased pad area
    * Standard Magnetic Selective Ride Control with track-level suspension
    * Wider, carbon-fiber front fenders with ZR1-specific dual vents
    * 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, exposed 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
    * Only two options: chrome wheels and a "luxury" package
    * Curb weight of approximately 3,350 pounds (1,519 kg)

    The specialized components of the new ZR1 work harmoniously to deliver the most powerful and fastest automobile ever produced by General Motors. Performance estimates will be announced closer to vehicle's summer 2008 launch.

    "Preliminary testing shows the ZR1 builds on the highly respected Corvette Z06 in every performance category, from acceleration and braking, to cornering grip and top speed," said Peper. "It all boils down to the power-to-weight ratio and the ZR1's is exceptional - better than the Porsche 911 GT2, the Ferrari 599 and even the Lamborghini LP640. In fact, the ZR1 is expected to be the first production Corvette to achieve a top speed of at least 200 mph."

    Supercharged LS9 engine

    The new LS9 6.2L small-block engine is the power plant the supports the ZR1's performance capability. The enabler of the LS9's performance and refinement is a large, positive-displacement Roots-type supercharger with a new, four-lobe rotor design. It is augmented with an integrated charge cooling system that reduces inlet air temperature for maximum performance.

    A sixth-generation supercharger developed by Eaton 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 LS9 is hand-assembled at GM's Performance Build Center, in Wixom, Mich., and incorporates specialty 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, ensuring 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 a new, stronger six-speed manual transmission and a twin-disc clutch that provide exceptional clamping power, while maintaining an easy clutch 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 - a change from the fifth-gear top-speed run-outs in the manual-transmission Corvette and Corvette Z06.

    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 enables a 25-percent reduction in inertia, thanks to smaller, 260-mm plates, corresponding to a pedal effort that is similar to the Corvette Z06's 290-mm single-disc system.

    The rear axle also is stronger in the ZR1 and features asymmetrical axle-shaft diameters that were developed after careful testing to provide optimal torque management. The axles are also 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 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 . Their advantage comes in low mass and resistance to wear and heat. In fact, the rotors should never show any 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 front pads are equivalent in size to the largest on any production car with a single-pad design - double that of the Corvette Z06's 70-sq.-cm. front pads.

    I'd be surprised if that "Curb weight of approximately 3,350 pounds (1,519 kg)" is accurate. The Z06 weighs less than that, and the ZR-1 has a bunch of carbon fiber components to make it lighter. I was assuming it would be more like 3,000 pounds.

    The z06 also has the same amount of carbon fiber, but i agree it should be lighter

    I wish that didnt have to supercharge it, now it seems like we are following ford with this super charger stuff. i think they could have put a 502 in it abd got the same or better hp. i prefer pure engine hp over all that turbo and super charge crap fells like your cheating when it not all motor, but thats just me thinking out loud

    It's not much different looking than a Z06.

    On a side not I think the window on the hood is stupid.

    And to think a small change of the pullies will put that thing at 700hp is just insane!

    That's where the C6-Z06 comes in my friend; 427CID under-rated at 505hp That's plenty N/A power right there to run with the best of them

    Well, of course it has to look like the Z06 (C6) we're still generation VI
    The body style of the Corvette won't change until generation VII comes along, which it would be within another 3-4 years perhaps?

    Power is power. This isn't the 60's where you needed a big block to go fast. This engine is more efficient than a huge motor would ever be.

    Right, I was just making a comment based on people saying it looked rice or ugly. A lot of the same people that make those comments drool over a Z06...it's not that much different.
