2010 Chevy Corvette Grand Sport – Click above to enlarge

Chevy is bringing back the Corvette Grand Sport, and unlike the one offered at the end of the C4's run in the mid-Nineties, this one sports a long list of performance upgrades that would make even Zora Arkus-Duntov proud. Rather than treating this revival as a special model with a limited run, Chevy has decided to ditch the Z51 package entirely and offer the Grand Sport that pushes the standard Vette's performance even closer to that of the Z06.

While the 430-hp (436-hp with the two-mode exhaust) LS3 V8 remains unchanged, wider front and rear fenders allow for 18- (front) and 19-inch (rear) wheels that are also wider than before. Larger brakes are included and the special suspension tuning is now even closer to that of the Z06. You'll also notice other Z06 elements like the front splitter, rear spoiler and functional brake ducts behind the doors. Unlike the Z06, you can order a Grand Sport with a manual transmission or the Vette's six-speed automatic with paddle shifters. If you're a true track hound, though, go with the manual that also comes with a dry-sump oil system, differential cooler and rear-mounted battery.

Though available as a convertible, coupe models also feature a removable roof. The Grand Sport can also be had in all four Corvette trim levels (1LT, 2LT, 3LT and 4LT) and any standard Corvette color, and a special heritage package gives a nod to the past by adding a pair of hash marks to the front fenders. The new Grand Sport is being announced at the 12th annual C5/C6 Corvette Birthday Bash at the National Corvette Museum in Bowling Green, Kentucky as we speak and pricing has yet to be announced, so stay tuned.

BOWLING GREEN, Ky. – Grand Sport. It's one of the most storied monikers in Corvette's illustrious racing heritage and it is returning the lineup. Chevrolet announced the new, 2010 Corvette Grand Sport at the 12th annunal C5/C6 Corvette Birthday Bash, held at the National Corvette Museum, in Bowling Green, Ky.

The new Grand Sport model combines the Corvette's LS3-based powertrain with unique, wide-body styling and a racetrack-bred suspension for a distinctive, starting grid-ready performer. It is offered in both coupe and convertible body styles, with either a six-speed manual or six-speed automatic transmission. The LS3 6.2L engine is rated at 430 horsepower (321 kW)* and 424 lb.-ft. of torque (575 Nm)* with the standard exhaust system. An optional two-mode exhaust system elevates the power ratings to 436 horses (325 kW) and 428 lb.-ft. (580 Nm).

The Grand Sport replaces the Corvette's previous Z51 package and brings a greater degree of handling performance, with wider wheels and tires; revised shock, stabilizer bar and spring specifications and specific gearing. The equipment enables cornering capability of 1.0 g, as well as a 0.2-second improvement in 0-60 acceleration vs. standard LS3-powered models.

Grand Sport coupe models equipped with the manual transmission are uniquely outfitted for racetrack competition, too, with a dry-sump oiling system, differential cooler and a rear-mounted battery.

The complete list of content and special features for the Grand Sport includes
  • Wider front and rear fenders – including specific front fenders with integrated Grand Sport badges
  • Z06-style front splitter and tall rear spoiler
  • Functional brake ducts and extra cooling
  • Unique 18-inch front and 19-inch wheels; painted finish standard and chrome finish optional
  • Large 275/35ZR18 tires in front and 325/30ZR19 tires in the rear
  • Z06-size brakes, including 14-inch (355 mm) front rotors with six-piston calipers and 13.4-inch (340 mm) rear rotors with four-piston calipers
  • Specific manual transmission gear ratios
  • Specific rear axle ratio on automatic-equipped modles

With its special equipment, the Grand Sport offers a unique blend of performance and amenities. Its suspension package approaches that of the Z06, but includes a removable roof on coupes (Z06 has a fixed roof) and, of course, the availability of a convertible body style. Also, the paddle-shift six-speed automatic transmission is offered, while a manual transmission is the only choice with the Z06.

All of Corvette's exterior colors are offered on the Grand Sport and an available Heritage package adds iconic front fender hash marks offered in four colors, as well as two-tone seats with Grand Sport embroidery. The Grand Sport can be ordered with 1LT, 2LT, 3LT and 4LT trim packages, too.

Grand Sport history
Envisioned by legendary Corvette engineer Zora Arkus-Duntov as a factory-built, lightweight and race-ready production model that would trump domestic and foreign road-racing competitors, the original Corvette Grand Sport was a promising idea stymied by GM's agreement to stay out of manufacturer-backed motorsports.

The planned 125 production models required for racing-class homologation were never built, but five prototypes based on the styling of the 1963 Corvette were hand-assembled under Duntov's watchful eye. And while they looked like production models, the prototypes were purpose-built racecars that shared little with their assembly-line cousins. Duntov also oversaw the Grand Sport engine program that featured a special, 377-cubic-inch small-block V-8 and used side-draft carburetors.

Although never officially sanctioned by General Motors, the five Grand Sport prototypes saw extensive racing experience throughout the 1960s in the hands of "private" racers who had strong contacts within Duntov's engineering circle. All five original cars are accounted for today and are among the most valuable in the collector market.

Chevrolet offered a limited-edition Grand Sport production model in 1996, commemorating the original racing cars and marking the end of the C4 era in Corvette production. All of the 1,000 examples were painted Admiral Blue and featured a white center stripe and red "hash mark" graphics on the left front fender, a graphic scheme that mimicked the look of some of the original racecars.

      who cares? arent there like another 20 corvette configurations? like this will save GM from bankruptcy, they need to start following through with their future production cars like the cruze, volt. things with PROFIT. and people will actually BUY.
        • 6 Years Ago
        Yeah you're right. The C06 Corvette def. needs to go to production!


        • 6 Years Ago
        So, what do you suggest? They roll over and make Camrys only? Chevy will emerge better than they ever were.
        • 6 Years Ago
        i didnt say that, i said they need to get the products they show at car shows at dealers. instead of just giving pics of "future" vehicles.
      • 6 Years Ago
      now that is a corvette i would buy, has most of the amenities of a Z06 and is a drop top, and remember, the base engine block is the same as the zr1's so you could go to town on the engine if you'd like, (forged internals, some aftermarket heads and a supercharger or turbo would produce some very nice results) this is what they should use as the baseline instead of the stock c6(which in my eyes is no better than buying a new camaro)
        • 6 Years Ago
        Agreed. The best of both worlds.
        For me, the z06 is a better package off the shelf but this has more tuning potential.
        It fits in real nice between the Z51 and Z06.
        I'm still surprised to see folks 'complain' that this is actually a functional improvement. I dont get it, why would a person who cares about Vette want another body kit and hope that the car isnt improved?

        There are plenty 'special edition' stickered Vettes for the c6. GM got it with this one. I may actually get this new over a pre-owned Z06,put a procharger and save the change.

      Ever since 1996 the Grand Sport has been my favorite "model" of Corvette. Through the C5s and now the C6s, I always said if I bought one I would do a GS clone one just because it's just a timeless design everybody knows what it is.

      As for the car in the pictures...red??? Available in all standard Corvette colors? This is a bad move to me because a GS is blue with red stripes on the fenders, without question. The upgrades are good, but in my opinion spreading out the upgrades to other colors doesn't honor the 1963 and 1996 Grand Sports like it should. Make the Grand Sport be blue with red fender stripes, and offer the upgrades to other Vettes, but not as Grand Sport packages.

      I guess I am a little senimental here, but it's a Grand Sport, they are meant to bring up sentimental feelings.

      If LS7 Z06 prices don't go down enough in 4 to 5 years, then I might pick up one of these used and give my G8 GT to a chick that I will have probably married by then...

      Thank you GM. Unfortunately I never appreciated your performance until I got my G8. It's going to be sad to see it go away.

      Noah: your comments are hilarious.

      This is the internet I don't have to prove S to you, but if you are ever in DFW give me a ring and I can give you a ride in my Z06, email: dfwjake@gmail.com

      I love my vette - and before GM slapped every Z06 owner in the face with this car I was behind them 100%. Your logic on why i don't own a Z06 is so backwards its amusing.

      If i did NOT own a vette I would be happy thing thing is coming out so I could have a cheaper Z06 LOOKING car, thing is I paid 75K for my Z06 and along comes this much cheaper much the same looking knock off for far less.

      I can't understand why people don't see this car for what it really is, selling out the image of the Z06 with a drop top but none of the actual engine parts ot make it faster.

      I actually kinda like the new front fender extractor vents, and the chevrons on the fender. (Blue with white or red chevrons would be nice...)

      Not the biggest fan of the wheels, and while better than C5, the C6's front bumper cover has always been a little to thick-looking with rectangular and wide-radiused details, and the GM-mandatory Playskool interior treatment.

      Knowing GM, it has a black box recorder, and mandatory OnStar cell modem.

      Nice car to look at, but due to those things, still wouldn't own one.
      • 6 Years Ago
      idk looks a little photoshopped to me. The front wheel well cracks me up because it's soo not round. Plus, the area around the vents are so vivid, it contrasts against the rest of the car.

      I'll believe it when its on Chevy's website.
        • 6 Years Ago
        You probably don't want to see the convertible trying to handle that kind of power.
        • 6 Years Ago
        There is a little black baffle just behind the tires on the wheel arches, front and rear, which makes the wheel openings appear to be "not so round". These are aero pieces from the Z06.
      • 6 Years Ago
      April Fools joke? Oh wait it's the 23rd....seriously though, is this what GM needs right now?
        • 6 Years Ago
        carmaniac, I wish i could of voted you down a few more times. Who cares if this is what GM needs right now, its a GrandSport! And its glorious.
        • 6 Years Ago
        Using mostly off the shelf parts to put together a $4000+ package that's mostly profit? Giving Corvette buyers the exact car they've wanted for the past 4 years? Making the base Corvette even more of a performance bargain? What's the problem?

        Contrary to popular belief, not everybody is lining up for the Prius and Volt.

      If they go into bankruptcy do you think these cars will sell for less?
        • 6 Years Ago
        These will not be on the dealers lots before they go BK. I would say they will hold their value as much as any Covette seeing as they will not be as common as the base version. Chevy needs to keep the Corvette, just improve the seats!
        • 6 Years Ago
        I've always loved the idea of the Corvette, but the interior always kills it for me. I'd support the idea of a revised interior on the same everything else...
      • 6 Years Ago
      Jeff Johnston who do you think your kidding ?

      Since the ZR1 has come out you Z06 owners have been conning dealers to sell you all the ZR1 carbon body parts that were confined to be only used for ZR1s
      Guys are fools spending $1200 plus for a carbon front spoiler and about the same for the rear one so you can look like a ZR1 and your crying about a Z06 that will be dead within the next year.

      Your the type of owner we true Vette owners like to get rid of and hope you go back to a riceball with fart pipes drifting in a parking lot.
        • 6 Years Ago
        Where in my post did you get that I was a ricer? with a fart can exhaust?

        The only thing Ive done to my Z06 is a Halltech Killer be intake, 2 piece slotted lightweight rotors, a mild2wild switch and some tint.

        I race my vette at Motorsports Ranch in Cresson TX - I havent done any cosmetic mods and even though your tone is very ugly I agree with you that I think spending all that money to make a Z06 look like a ZR1 is stupid.

        I don't understand the obsession that people have in taking something designed AS something else and making it look like something it's not. I find your tone to be not in line with what a "true vette" man would actually say. My attack is on GM and their decision to try and bring this out at the worst possible time. You make the comment of dressing a Z06 as a ZR1, logically you would think you would agree with me that dressing a base C6 as a Z06 from the factory is something you wouldn't exactly like either. I'd like to have a rational discussion with you, but your argument and attack on me contradicts any point I think you are trying to make. My name is Johnson too - not Johnston.

        As a "true vette person" i would figure you too would be sad to see the Z06 getting ripped off and sold down river for a quick sale. I'm just really confused because your thoughts do not line up with your words buddy.

      I generally don't like convertibles, but this one's at the top of my list. Love it!
      • 6 Years Ago
