Corvette ZR1 - Click above for high-res gallery

General Motors can clearly use all the money it can get, and for the 2010 model year, you'll have to fork over more of it to get behind the wheel of a ZR1. The 2010 638 hp supercar will cost you $109,530; an increase of $2,910 over last year's model. A larger MSRP isn't a good thing, but according to Corvette Blogger, many dealers were already charging $10,000 over sticker for an '09 model, so this could be the General's way of getting a little bigger piece of the action.

For all that dough, you still get the most powerful production Vette of all-time – and a few new items as well. The 2010 model now comes with standard side curtain airbags, launch control and Performance Traction Management System. PTMS, by the way, gives the driver more control over traction settings when in competition mode.

Also new for 2010 is the ability to choose from a far greater array of colors including Torch Red paint, Competition Gray alloys, and a Cashmere toned interior. Hit the jump to pour over the press release.

PRESS RELEASE:

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.

      Regardless of how you feel about this car, I think we can (almost) all agree that those original chromies looked tacky and needed the axe. Now about that hood...
      • 6 Years Ago
      Pushrods? No thanks. Show me you love me with a new design, one that's less than 55 years old. How about adding some ingenuity, more capacity and a blower to the 3.6 V6 that's actually a modern design?
        • 6 Years Ago
        I want breathing, from 4-5 valves/cylinder and variable valve timing. It takes GM a supercharger to approach the output/liter of an S2000 from a decade ago. You can pitch a bitch about rice or sauerkraut, but this is an ancient design, long surpassed by almost everybody who's had to pay real money for fuel for years. GM can do it. They have a fairly modern 3.6L V6.
        And the cart/truck springs don't impress me one bit. The shocks do. They're no longer exclusive, either. That's how good they are. I wish GM would put an interior in this car as good as they're capable of. The materials, switch gear and fits in my Miata are better quality.
        • 6 Years Ago
        First of all, learn to math. LS9 has more than 100 hp/liter.

        Secondly, all these engines make more horsepower per -valve- than most cars out there. Woot, I can make retarted arguements too!
        • 6 Years Ago
        I know a little more than you think. I've been an engineer nearly fifty years and have worked on this engine and others since I was 14. Any engine of the size of the Chevy will have plenty of torque regardless of its design. Your comments are both ignorant and insulting. Grow up.
        • 6 Years Ago
        TRULY... one of the dumbest... perception based comments I've seen in the last day from this site. The LS V8s are some of the most advanced engines on the planet.. . Chevy Engineers from the 50's wouldn't recognize this engine... sorry, but the current LS3-LS9 are as advanced as anything BMW has.. not to mention the Germans.

        the OHV stigma... for some reason despite the engine's contemporary configuration, superior HP and fuel efficiency and low maintenance... GM still allows peoples idiotic perceptions... caused by even more idiotic Media, to influence their use of this engine company wide as the V8 of choice. They have tested successfully Direct-Injection in the Small-Block as well as HCCI.

        We currently have these well known OHV engines on the market... and if U are lucky, u have driven at least one car that they show up in and can agree or disagree with what I'm saying:

        5.3L 303HP/323 lbs AFM

        6.0L 361HP/385 lbs AFM

        6.2L 402HP/402 lbs AFM

        6.2L 415HP/415lbs

        6.2L 426HP/420 lbs

        6.2L 430-436HP/424 lbs

        7.0L 505HP/470 lbs

        6.2L 556HP/550 lbs S/C

        6.2L 638HP/604 lbs S/C

        These are just the CAR V8s... I did not touch truck the ones simply because there is no need. This full range of V8 engines which have been mainstays on Wards "Best Engines" for years in their previous and current configs. should be held up in HIGH REGARD with in GM, and in the automotive community as a whole.

        The only other maker that matches GM's V8s in terms of power and durability is Mercedes Benz. I always liken it to the fact that both makers have been around for almost the same amount of time, and operated in every single country on the planet as the other... Giving both a diversity in Engineering that seemingly is only rivaled by each other.

        One thing that Mercedes doesn't do in a comparison between the two... is match GM's efficiency... These OHV engines in some cases are as efficient as many other makers's V6s. Imagine a Chevy Tahoe weighing 1000 lbs more than a Honda Pilot... getting almost identical F/E as that Pilot while touting about 60 more HP.

        Its your silly attitude that has M5, 911 Turbo, and such.. getting their asses beat out their on the road by the sweetness that is... SMALL BLOCK HEAVEN
        • 6 Years Ago
        Mr. Ed: How many "New & Improved" engines have Audi, BMW, Ferrari, Jaguar, Toyota, Honda, MB and even GM (Quad 4 and Northstar) themselves have built and discarded since the LS motors came into existence?

        This motor, is the best most consistent engine built this side of the gas turbine.

        The only thing this motor needs now is Direction Injection. I'm betting that the 5.3 liter LS motor could be promoted to base Corvette duty when DI hits the LS motor. A supercharged 5.3DI motor would be nice in the CTS-V.
        • 6 Years Ago
        Show me a DOHC that has over 400 ft-lbs of torque at 1300 rpm.

        That's right, you can't find any.

        Your Honda S2000 as an example? That thing has 120 hp/l naturally aspirated, but rolls like a Honda Civic at low rpm. Sorry, I'd take a low-tech V-8 that has a broader torque curve than a glorified DOHC that needs 5000+ rpm to haul ass, like those S2000s or Ferraris. But you don't know anything about cars. All you know is some made-up fanboy stat called "hp per liter" and overlooking the fact that the OHV has been dominating LeMans in GT1 so much, or that a good chunk of RX-7 owners replace their rotaries (ZOMG 100hp/l) with LS1 Corvette engines.

        Seriously Mr. Ed, you know nothing about engines.
        • 6 Years Ago
        Mr Ed,
        If you want to see something innovative, I encourage you to wikipedia the Corvette's suspension and read about the electromagnetic dampers and composite transverse leaf springs. Also, if you want something more engine specific, read about the Corvette's inverted 2.3 liter Eaton supercharger with intergrated air charge coolers built into the intake plenum. There are some really interesting technologies on this car that few or no other cars have.

        Given this vehicle's capabilities, pushrods obviously aren't hurting it's performance...
        • 6 Years Ago
        Technology less than 55 years old? I assume you mean overhead camshafts... Which date back to at least 1912 when Fiat used them...

        There's nothing wrong with pushrods.
        • 6 Years Ago
        All the versions of this engine give less than 100HP/L. OHC heads would solve it. GM won't do it and I won't buy it. And don't forget the Cavalier quality interior...
        • 6 Years Ago
        It took a blower to get over a hundred horse/liter. There are plenty of engines (all OHC) that beat that without the extra pressure. And people who've worked on the first V8's sure will know how to wrench the new ones. It's nice to be able to pay for the tooling with some mods over 55 years. I expect and pay for better.
        • 6 Years Ago
        considering DOHC engines have been around since the 1910s and the Wankel in the 50s, what kind of engine do you consider "New"?
      • 6 Years Ago
      alright - this is autoblog, we all love cars right? why do some people feel the need to bash a car because of something it has. The ass hats here bashing because it uses pushrods? Lame.

      So you think a 7 Liter engine, that revs to 7000rpms, pushes out 500+HP, and gets close to 30mpg on the highway is "low tech"?

      Whoever is stalking me and doesnt like it when i talk about my Z06 will probably chime in, but we all know you are just jealous. The seats do suck in the current vettes. They are great for city, highway driving but you will know what I'm talking about if you ever hit a track. Having to use your knees and hands just to keep yourself in the center of the seat isnt fun when you are trying to concentrate on driving.

      For 100K+ I would expect some better seats GM. If you can pull it off in your 550HP+ caddy, why not the vette? At LEAST make it an option, I'd give up my sat nav system + cash for a good set of seats.
      • 6 Years Ago
      I wonder how much this PTMS could help this car around a road course? I would think that even an experienced driver could use some help managing 638 hp out of the corners. Perhaps this system should be tested around an old track in Germany....
      • 6 Years Ago
      What interests me is the Performance Traction Management:
      "When full throttle is applied upon exiting a corner, it automatically manages acceleration dynamics."

      I've heard that this easily improves lap times for all but the best drivers... I'd love to see it in action.
      • 6 Years Ago
      how hard is it to put some nice seats in this car! I dont think it will add that much money anyways.
      • 6 Years Ago
      What happened to the obtainable super car?? Plus the GTR is cheaper and it holds its own against the ZR-1, plus it has good seats.
        HotRodzNKustoms

        You sir, just fail.

        "What happened to the obtainable super car??"

        That would be the Z06

        - GTR: $85k

        Some people like GOOD LOOKING fast cars and not the ugly aspirational car of Joystick Lovin' Nerds who think Fast and the Furious I, II, III, and IV were all Osca worthy
        • 6 Years Ago
        Wow these guys act like you called their baby picture ugly!
        @Aron spending 85K on a car and voiding the warranty the transmission is better than spending 100K on a car from a bankrupt company with probably no warranty at all. Besides where are you going to drive these beasts hard enough to break them?
      • 6 Years Ago
      Definitely an amazing car, I do agree about the seats/interior. And no, it's not nitpicking. Sure you can say that if you can afford a car that costs $110k you can afford to swap stuff out, but you shouldn't have to.

      In regards to the GTR thing, people need to get over that. You can race that car all day on a track and as long as you don't actually abuse the car it will be covered under warranty. Only having the tranny fail while having VDC off(which was required to use the launch control, which was never an advertised feature of the car) would void your warranty. And in reality, there's really no reason to even have the VDC off it's apparently pretty conservative and there's really nothing you can throw at that car to warrant having it off during spirited driving. In fact most of the incredible numbers that car put up were without the use of launch control with VDC on. The ZR1 and GTR are both incredible performance cars at great prices for the performance you get. The whole 1st production year tranny thing is the only thing the GTR haters have to use against the car so they'll never let it go.
      • 6 Years Ago
      Man after all the awards the LS engines has won, the fact that the pushrod scared away the GT1 competition in LeMans/ALMS, people still think pushrod is some sort of POS?

      Dude, I don't care about how an engine is made, as long as its reliable (and the LS engines are), compact and lightweight (yes, lighter than DOHC, you can see them stuffed in RX-7s no problem) and has power and torque. Yeah, most naturally aspirated DOHCs like the ones in BMWs and Ferraris has some lol torque at 1500-2000 rpm, but not the LS series.

      Did I mention that the BMW M3 (414 hp) has the same 14city/20hwy mileage as the ZR1 (638 hp)? Not to mention a better, flatter, higher torque curve?

      Not knocking on the BMWs here, but just my unfortunate example to prove a point that these LS engines are among the best internal combustion engines in production right now.
      • 6 Years Ago
      STILL... $50K cheaper than it should be.. maybe even $100K less than it should be. The only thing that a Ferrari has over this car is a slightly... and I mean SLIGHTLY better interior. They both have the same racing heritage, and all the "Wish they Could Have Ones" in the world who never driven one can not deny that they perform damn near the same. Hell this goes for the Base Vette and Z06 as well.

      Oh.. and please don't anyone say... "Ferraris are HANDBUILT" because I will counter with

      : "Every example of HAND BUILT I've seen come outta that company lands U in the SHOP 300 days outta the 365 day in the year"

      THe ZR1 is perfection
        HotRodzNKustoms
        • 6 Years Ago
        Having owned many handbuilt cars I have to agree, all that handbuilt means is its $hit and not as well built as a car they don't make by hand.
      • 6 Years Ago
      Is there any photoshop with the headlamp fills blackened?

      Since this car has been born I have kinda (platonic) issues with how it looks, in particular the headlamps - I can't stand the body-color under the transparent cover. (Same applies to Ferrari 360.)
        • 6 Years Ago
        Unless the car is BLACK.. U can exchange the body colored HEADLIGHTS for black ones which does what U are asking. Tinting the lenses also would do it but that could damage the light as heat emmited from the HIDs is a bit intense and the Tint may cause issues
        • 6 Years Ago
        Yes, that would be it... I will just google again then, harder, deeper :)
        thnx
        • 6 Years Ago
        The headlights on the C6 Vette are criminally cheap looking.
      • 6 Years Ago
      Let me guess you've never owned/driven a v8 car. Can you name any "modern" DOHC engine that has equal or more torque and HP throughout it's entire powerband that can fit in an engine bay the size of the Vette and have the car weigh in as light as this car?

      BTW OHC dates back to the 1920's OHV dates back to the 1950's, so which one is more modern again?

      And no real supercar should be burdened with a blown v6. It just can't make great sounds unless you think a blender sounds good, the big bore v8 rumble makes a car feel even more special than it may be.
        • 6 Years Ago
        You've obviously never heard a NSX with a blower.
        • 6 Years Ago
        Wrong. OHV pushrod engines were invented in the early 1900s by David Buick. OHC came a few years later in the 1910s
