Supercharged, 6.2-liter V8? Check. Seven-speed manual? Check. Obsession with weight? Check.

What did you expect when Chevrolet said it was bringing a new Corvette variant to the 2014 New York Auto Show? Maybe a sticker and trim package, like the C6 Corvette Grand Sport or a tie-in deal like the Black Widow car from Chicago? On the opposite end, maybe there was an even more hardcore Z06 waiting in the wings. Who knew?

In the end, the answer shouldn't be surprising. This is the 2015 Chevy Corvette Z06 Convertible. Designed to make mincemeat of cars like the Porsche 911 Turbo Cabriolet, everything that's good about the Z06 Coupe can be found on the droptop. Supercharged, 6.2-liter V8? Check. Seven-speed manual? Check. Same obsession with weight? Check.

It's that last one that's most impressive. Traditionally, convertibles weigh a good bit more than their hardtopped brethren, thanks to the top mechanism itself, as well as extra bracing and structural enhancements to maintain rigidity. For example, a Camaro SS Coupe is 264 pounds lighter than an equivalent convertible. It's one of the big reasons we've never had a Z06 Convertible before (the C6 427 Convertible was the closest we came in the last generation). With the C7 Z06 Convertible, though, there is no need for extra bracing thanks to an ultra-stiff aluminum frame. The result is a convertible that is very nearly as light as a coupe.

"Until recently it was not possible to create a lightweight, open-roof structure strong enough to cope with the braking, cornering, and acceleration of Corvette's top performance models," said Corvette chief engineer Tadge Juechter. "The frame for the Z06 convertible leverages advancements in computer-aided engineering, metallurgy, and manufacturing techniques – many of which were not available just five years ago."

Based on Juecter's comments, it sounds like the only real difference between this car and the Z06 hardtop will be the amount of sunlight let in. The blown V8 still produces 625 horsepower and 635 pound-feet of torque, which is transmitted to ultra-fat, ultra-sticky Michelin tires on the rear axle through the owner's choice of a seven-speed manual or an eight-speed automatic. Steel or carbon-ceramic Brembo brakes are available, as are all the aerodynamic enhancements that allow the Z06 Coupe to slice through the air. And naturally, the suspension is just as track-ready as the hardtop, complete with a specially tuned version of Magnetic Ride Control.

On paper alone, there is a whole lot to like about the new Z06 Convertible. We'll be eagerly awaiting the chance to drive one. Take a look below for the full press release, direct from Chevy.

Drop-top Supercar: 2015 Corvette Z06 Convertible

NEW YORK – Chevrolet today introduced one of the most capable drop-tops on the market: the 2015 Corvette Z06 Convertible. With at least 625 horsepower, and 635 pound-feet of torque, the Z06 is also the most powerful convertible ever produced by Chevrolet.

"The Z06 Convertible is a world-class supercar in every sense," said Mark Reuss, executive vice president, Global Product Development. "Only a handful of convertibles in the world bring more than 600 horsepower and 600 pound-feet of torque. Even fewer can match the advanced technologies, aerodynamic design, and visceral driving experience of the Z06 Convertible."

This is the first Z06 Convertible offered from the factory since 1963 when the Z06 option package was introduced for endurance racing. Records show only 199 Corvette orders with a Z06 package that year, including one convertible.

Recent technological advancements enable the building of a modern Z06 Convertible, said Corvette chief engineer Tadge Juechter

"Until recently it was not possible to create a lightweight, open-roof structure strong enough to cope with the braking, cornering, and acceleration of Corvette's top performance models," Juechter said. "The frame for the Z06 convertible leverages advancements in computer-aided engineering, metallurgy, and manufacturing techniques – many of which were not available just five years ago."

The aluminum structure is 20 percent stiffer than the previous, fixed-roof Z06. As there are no structural reinforcements needed for the Z06 Convertible, its curb weight is nearly identical to the Z06 Coupe. They also share the same chassis tuning, powertrain output, driver technologies and equipment options – including the Z07 Performance Package, which adds Brembo carbon-ceramic matrix brakes, Michelin Pilot Sport Cup tires and adjustable front- and rear-aerodynamic components.

"The most impressive aspect of the Z06 Convertible may be its performance bandwidth," said Juechter. "Very few cars on the market can match its combination of extreme, supercar levels of performance; the flexibility for daily driving and long-distance commuting; and the 360-degree, open-air driving experience only true convertibles can offer."

All-aluminum, high-tech foundation
The Corvette Z06 Convertible represents the culmination of more than four years developing an all-new, all-aluminum structure for the seventh generation Corvette. That structure, built at General Motors' Bowling Green Assembly plant, was designed to the specifications of the Corvette Stingray, Corvette Z06 and the Corvette Racing C7.R.

"We wanted a frame that was lighter than the steel frame of the previous Corvette, yet strong enough for both a 600-horsepower convertible and a 24-hour endurance racer," said Ed Moss, engineering group manager for Corvette structures. "That would not have been possible without improvements in computer-aided engineering software, which allowed us to model more than 17,000 frame iterations, with each iteration improving strength and stiffness, while reducing mass."

The team used nearly 186,000 computational hours of modeling to develop the frame. It features main rails composed of five customized aluminum segments, including aluminum extrusions at each end, a center main rail section and hollow-cast nodes at the suspension interface points. The gauge of each segment varies in thickness from 2mm to 11mm, tailored – along with the shape – to meet the strength and stiffness requirements for each frame section with minimal weight.

These components are assembled using many advanced manufacturing processes, including:
• 439 spot-welds using a GM-patented process that uses a unique electrode designed specifically for aluminum
• 188 Flowdrill-machined fasteners installed by a high-speed drill that extrudes the frame material to create a strong, integral collar tapped for bolt-on fasteners
• 113 feet of structural adhesives used in conjunction with welding and fasteners to increase overall frame stiffness
• 37 feet of laser welds, which join frame sections via a precise beam of high energy that minimizes heat beyond the weld area for improved structural accuracy.
The only structural differences between the Z06 Coupe and Convertible are provisions for mounting the power-folding top, and repositioned safety-belt mounts.

High-performance aerodynamics
Like the structure, only minor design changes distinguish the Z06 Coupe from the Convertible. The Z06 convertible features an electronic top that can be lowered remotely using the car's key fob. The top can also open or clos on the go, at speeds of up to 30 mph (50 km/h).

With the top up, the Z06 Convertible is designed for a refined driving experience. A thick fabric top, offered in four colors along with sound-absorbing padding and a glass rear window, contributes to a quiet cabin and premium appearance.

Behind the seat backs, dual accent panels – either Carbon Flash-painted or available with exposed carbon fiber – enhance the character lines of the tonneau cover. Corvette Stingray's signature "waterfall" design originates in the valley between the nacelles, bringing the exterior color into the interior.

The power-operated tonneau cover necessitated moving the air intakes for the differential and transmission coolers from the rear quarter panels on the Z06 Coupe to the underbody of the Z06 Convertible.

Otherwise, both models share the same, performance-driven aesthetic.

"Practically every exterior panel serves a functional purpose to meet the performance goals of the Z06," said Tom Peters, Corvette design director, "The flared fenders accommodate larger, wider wheels and tires for more grip. The larger vents provide more cooling air to the engine, brakes, transmission and differential for increased track capability. The more aggressive aerodynamic package generates true downforce for more cornering grip and high-speed stability."

Both Z06 models are fitted with Michelin tires (Pilot Super Sport tires for the Z06; Sport Cup 2 tires with the Z07 package): P285/30ZR19 front, and 335/25ZR20 rear.

The tires are mounted on lightweight, spin-cast aluminum wheels (19 x 10 inches in front and 20 x 12 inches in the rear). Their open, ultralight design showcases the massive Brembo brakes, which contribute to the design:
• The Z06 features two-piece steel rotors, measuring 14.6 x 1.3-inch (371 x 33 mm) front and 14.4 x 1-inch (365 x 25 mm) rear, with aluminum six-piston and four-piston fixed calipers, respectively
• The Z07 package adds larger, 15.5 x 1.4-inch (394 x 36 mm) front and 15.3 x 1.3-inch (388 x 33 mm) carbon ceramic-matrix brake rotors for consistent performance lap after lap. They collectively save 23 pounds over the standard Z06 rotors.

Both Z06 coupe and convertible will be available with one of three, increasing levels of aerodynamic downforce:
• The standard Z06 features a front splitter, spats around the front wheel openings, a unique carbon-fiber hood with a larger vent, and rear spoiler
• An available carbon-fiber aero package delivers aerodynamic downforce four times greater than the standard Z06. It adds a carbon fiber front splitter with aviation-style winglets, carbon fiber rocker panels, and a larger rear spoiler with a fixed wickerbill – a small, vertical tab at the edge of the spoiler that significantly increases downforce. The package is available in black or a visible carbon-fiber finish
• The available Z07 package adds larger winglets to the front splitter, along with an adjustable, see-through center section on the rear spoiler enabling customers to tailor the aerodynamics to their preference.

Compared to the Corvette Stingray, the Corvette Z06 fenders are 2.2 inches (56 mm) wider at the front, and 3.15 inches (80 mm) at the rear. Those extensions give the Corvette Z06 a wider, lower appearance further emphasized by a unique rear fascia. It incorporates the same taillamp assemblies as the Stingray, but on the Z06 the taillamps are pushed approximately three inches farther apart, toward to edges of the body.

The exterior design also reflects the increased cooling required for the new Corvette Z06. For example, the mesh pattern on the front fascia was designed to deliver the most possible airflow to the supercharger's intercooler heat exchanger, so much that the mesh grill directs more air into the engine bay than if the grille was removed.

The unique grille also features dedicated brake-cooling intakes and wider grille outlets on the bottom serve as air diffusers. A larger hood vent allows air driven through the grille to exit through the hood rather than being forced under the car, which could create lift.

Standard front and rear brake-cooling ducts, including Z06-signature rear ducts integrated in front of the rear fender openings, are also part of the functional design changes.

The Z06 benefits from interior details designed for high-performance driving, first introduced on the Stingray, including a steel-reinforced grab bar on the center console for the passenger and soft-touch materials on the edge of the console, where the driver naturally braces during high-load cornering.

Like the Stingray, the Z06 comes with two seating choices: a GT seat, for all-around comfort, and a Competition Sport seat with more aggressive side bolstering, which provides greater support on the track. A magnesium frame structure for both seats provides greater rigidity and strength compared with steel frames.

Unprecedented attention to detail and build quality complements the Corvette Z06's performance. All models feature a fully wrapped interior, with every surface covered by premium, soft-touch materials. Available materials, depending on the trim level, include Napa leather, aluminum, carbon fiber and micro-suede.

The interior also features a flat-bottom steering wheel with a carbon fiber center spoke. The Z06 comes in five interior colors, including two that are unique to Z06 – blue and dark gray.

Supercharged, efficient performance
The heart of the 2015 Corvette Z06 is the all-new LT4 6.2L supercharged V-8 engine, expected to deliver at least 625 horsepower (466 kW) and 635 lb-ft of torque (861 Nm). To balance performance and efficiency, the LT4 leverages the same trio of advanced technologies introduced on the Corvette Stingray: Direct injection, Active Fuel Management, or cylinder deactivation, and continuously variable valve timing.

These technologies – combined with the fuel-efficient multi-speed transmissions, aerodynamic design and lightweight construction – help make the new Z06 surprisingly fuel efficient.

"The supercharged LT4 engine delivers the greatest balance of performance and efficiency ever in the Corvette," said John Rydzewski, assistant chief engineer for Small-Block engines. "It is one of the world's only supercharged engines to incorporate cylinder deactivation technology, enabling it to cruise efficiently on the highway with reduced fuel consumption, but offer more than 600 horsepower whenever the driver calls up its tremendous power reserve."

The supercharged LT4 comes with a standard seven-speed manual transmission with Active Rev Match, or an all-new 8L90 eight-speed paddle-shift automatic transmission designed to enhance performance and efficiency. The seven-speed manual incorporates rev-matching technology for upshifts and downshifts. A new dual-mass flywheel and dual-disc clutch deliver greater shift quality and feel through lower inertia.

The eight-speed automatic is tuned for world-class shift-response times. Smaller steps between gears keep the LT4 within the sweet spot of the rpm band, making the most of the output of the supercharged engine for exhilarating performance and greater efficiency.

"There's no trade-off in drivability with the new 8L90 eight-speed automatic transmission – it was designed to deliver performance on par with dual-clutch designs, but without sacrificing refinement," said Bill Goodrich, assistant chief engineer for eight-speed automatic transmissions. "It is also the highest-capacity automatic transmission ever offered in a Chevrolet car."

Featuring four gearsets and five clutches, creative packaging enables the GM-developed eight-speed automatic to fit the same space as the six-speed automatic used in the Corvette Stingray. Extensive use of aluminum and magnesium make it more than eight pounds (4 kg) lighter than the six-speed. Along with design features that reduce friction, the 8L90 is expected to contribute up to 5-percent greater efficiency, when compared with a six-speed automatic.

Track-proven technologies
The 2015 Corvette Z06 Coupe and Convertible leverage the technologies introduced on the Corvette Stingray, with unique features and calibrations tailored for its capabilities.

"Our mission with the seventh-generation Corvette was to make the performance levels more accessible, enabling drivers to exploit every pound-foot of torque, every 'g' of grip and every pound of downforce," said Juechter. "It's a philosophy we introduced with the 460-horsepower Corvette Stingray – and one that's even more relevant with an estimated 625 horsepower at your beck and call."

The new Z06 retains the SLA-type front and rear suspension design of the Corvette Stingray but uniquely calibrated for the higher performance threshold. The third-generation Magnetic Selective Ride Control dampers, adjustable for touring comfort or maximum track performance via the standard Driver Mode Selector, are standard on Z06.

Like the Stingray, the Driver Mode Selector tailors up to a dozen features of the Z06 to suit the driver's environment, including:
• Launch control: Available in Track mode for manual and automatic transmissions, providing maximum off-the-line acceleration
• Traction control: Weather mode tailors traction control and engine torque for driving in inclement conditions
• Performance Traction Management: Available in Track mode and offers five settings of torque reduction and brake intervention for track driving
• Electronic Limited Slip Differential: Adjusts the rate at which the limited slip engages, balancing steering response and stability in different driving conditions with more aggressive performance in Sport and Track modes.

The smart electronic limited-slip differential, or eLSD, is standard. It features a hydraulically actuated clutch capable of infinitely varying clutch engagement. The system enhances all aspects of performance by constantly tailoring the clutch-pack engagement based on a unique algorithm that factors in vehicle speed, steering input and throttle position to improve steering feel, handling balance and traction.

Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 140 countries and selling more than 4.9 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature spirited performance, expressive design, and high quality.

      God that blue is gorgeous. Whenever I build my C7 on the Chevy website(because odds are thats the closest ill ever come to owning one lol) I always go with black on black but that color is beautiful. I do know one thing I would do if I owned that car and that would be to black out those amber reflectors, they look really out of place.

        And black out the rear stop lights while you're at it, so people behind you can't see whether you're braking or not. Brilliant! /sarcasm

      It's gonna be interesting to see how the SCCA and other sanctioning bodies deal with these cars (for those owners who actually track them). Most sanctioning bodies won't let verts do track days unless they've got a cage, rollbar, or hard top.

        The HPDE I instruct for uses the "broomstick rule". It'll be interesting if the aftermarket comes up with a rollbar solution. But I expect anyone serious about the track will get a Z06 will get the coupe. The convertibles will be left with for the gold chain set.

          Audisp0rta4, 911s have pop-up roll bars. For some organizers (though not many), that's sufficient for approval to run at the track. But Corvettes have no rollover protection at all, which frankly would concern me a bit even if I weren't at the track....

          • 10 Months Ago
          @JayP
          Audisp0rta4, the broomstick rule determines whether a convertible is approved to run at the track, and it works like this: a broomstick (or similar object) is laid such that one end rests on the top of your windshield frame and the other end rests on the top of your roll bar. The top of both the driver and passenger's helmets must be under that broomstick. Some organizers specify that they must be under with an inch or more gap between the helmet and broomstick. 911s I assume would fail this test because their popup roll bars don't come up until the car detects a rollover, so they can't be tested in advance -- and of course even if they would be tall enough, there's always the risk that a mechanical failure might prevent them from deploying when they're needed. I don't think the 911 provides a way to raise them manually.

          I'm not familiar with the broomstick rule, but my friend used to take his 911 cab to a few track days at Laguna, Thunder Hill and Sonoma. He didn't have a cage. I guess it depends on the sanctioning body. But yes. Anyone serious will just buy the coupe.

      My wife wants an automatic C7 convert. I want the Z06. Sad to say to all the die hards but now that this is an automatic convert Z06 this will be the ultimate compromise. I really can't see anything else coming close to the performance, price , and livability a this. We would love to have this car and I will seriously consider buying one. I'm sure it will be a blast to drive even if it's not the perfect track car. This car looks awesome and I can't wait to drive one....maybe buy one

      I'm a little surprised and confused. The new Z06 Coupe will for the first time include a removable roof panel, which stows easily in the trunk. I understand that's a bit more effort and allows a bit less light in than pressing a button to drop the entire roof and rear glass, but I wouldn't have expected that difference to justify a separate model. There's also the fact that unless this new Z06 Vert includes pop-up roll bars (previous Corvette verts haven't), then this model will be banned at most track events, which kind of defeats the point of having a Z06.

        1. Personally I'd be happy with a targa top (Corvette coupe, Elise, NSX, etc.) but there seems to be enough people out there that prefer one over the other that other automakers, such as Porsche with their 911, can produce both a targa and traditional vert and have both sell. 2. Even pop-up roll bars are banned in many events; a fixed roll bar is the ONLY way many events (though not all) will allow you on a track. 3. Some folks just want the faster drivetrain and racy bits on a convertible without ever planning on driving the car on a track. Different strokes...

      The C6 Grand Sport came with previous Z51 package (no longer available after GS existed), Z06 wheels/tires, body panels, and dry sump oiling. A bit more than a "sticker and trim package". Corvette is certainly guilty of sticker and trim packages unfortunately, but the C6 GS was not one of them.

      Hey, if you can get an Aventador, or 650S in a roadster version, why not a Z06? I love it! But should come with an active roll bar IMHO.

      This car is still lacking passion in design...interior looks terrible and childish...hell even the engine bay looks cheap..people dont understand that GM can attempt to compete with Porsche Audi Ferrari etc but its not about the track numbers and power...its about the experience and quality and brand when your purchasing a car like Porsches . When you tell someone that you drive a Porsche or A Ferrari etc study their reaction...now mention you drive a corvette its like oh? I see your 40 years and still act like a child...

        I love how you say this car lack passion, and then turn around and mention Audi in a favorable light. It's the snobby/elitist mentality that gives the European brands a bad name, and could care less what some know-nothing yuppy with an Audi, who probably doesn't even know how to unlatch the hood of his car thinks of me. This car IS about the track numbers, not some status symbol for tools to cruise around in while thinking everyone's in awe of them. Audis are dime a dozen, so owning one really doesn't set one apart like you think, and in south Florida, it seems every Guido there drives either an MB, Audi, BMW, or Porsche.

        Ok so we know a Ferrari, Porsche etc are very nice cars and I agree that there is a whole "experience" with their ownership. However if you buy one just because of what image you want to portray to others your are a tool. Just like all those European exotics, the Corvette has a uniuqe ownership experience. All of us on here are driving enthusiasts in one form or another and with that being said , the Corvette will always have its place amoung the world sports car arena.

        The Corvette looks childish because??? Because it has a black, all leather interior with bits of aluminum, carbon fiber and racing style bucket seats?! Because you can opt for red, tan or alcantera inserts? Dafuq you talkin 'bout foo. That's the same sh!t that's available in a Ferrari or Porsche. The only difference is that the Z06 will blow the doors off any Porsche in the same price range and most (maybe all) Porsches/Ferraris under 500k when it hits the track. There's nothing childish about the Corvette. Everything on that car has been put there to help it embarrass cars costing 2-3x as much as the vette. The interior may not be AS substantial as a 100-200k 911, or a 200-350k Ferrari, but the performance is. The funny thing is that ******* like you will continue to hold the European brands on a higher level than the car that kicks their ass, because your manhood (or lack thereof) relies on what others think of you. You're not a true car enthusiast. I will agree that the engine cover/blower assembly looks terrible though. But even that is for a reason. They compacted everything to maintain a low profile. And flat is never beautiful. :/
