2015 Chevrolet Corvette Z06 Convertible was just introduced. Like its coupe sibling it delivers 625 horsepower (466 kW) and 861 Nm (635 lb-ft) of torque, making it the most powerful convertible ever produced by Chevrolet. The car is built on an aluminum structure, which is 20 percent stiffer than the previous. Its curb weight is nearly identical to the Z06 coupe. Both cars share the same chassis tuning, powertrain output, driver technologies and equipment options, including the Z07 Performance Package. The latter adds Brembo carbon-ceramic matrix brakes, Michelin Pilot Sport Cup tires and adjustable front- and rear-aerodynamic components. Corvette Z06 Convertible features an electronic top that can be lowered remotely via key fob. The top can also open or close on the go, at speeds of up to 30 mph (50 km/h). The thick fabric top is offered in four colors along with sound-absorbing padding and a glass rear window. Behind the seat backs there are dual accent panels in either Carbon Flash-painted or with exposed carbon fiber. Both versions of the vehicle share the same aesthetics. They are fitted with Michelin Pilot Super Sport tires for the Z06 and Sport Cup 2 tires for the Z07 package. Precisely, they are in size P285/30ZR19 at the front and 335/25ZR20 at the rear. Of course, they come coupled with spin-cast aluminum wheels: 19 x 10 inches at the front and 20 x 12 inches at the rear. 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. On the other hand, 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. They collectively save 23 pounds over the standard Z06 rotors. In terms of aerodynamics, 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. In addition, there is an available carbon-fiber aero package that adds a carbon fiber front splitter with aviation-style winglets, carbon fiber rocker panels, and a larger rear spoiler with a fixed wickerbill.  The package is available in black or a visible carbon-fiber finish. As an option, there is also available Z07 package with larger winglets to the front splitter and see-through center section on the rear spoiler. 2015 Corvette Z06 features wider and lower appearance. Its front 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 unique grille also features dedicated brake-cooling intakes and wider grille outlets on the bottom serve as air diffusers. Z06 Convertible also benefits from interior enhancements such as steel-reinforced grab bar on the center console for the passenger and soft-touch materials on the edge of the console. It comes with two seating choices: a GT seat, for all-around comfort, and a Competition Sport seat with more aggressive side bolstering. The interior is fully wrapped with Napa leather, aluminum, carbon fiber and micro-suede. It 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.  At the heart of this cabrio is the new LT4 6.2L supercharged V-8 engine. It delivers at least 625 horsepower (466 kW) and 635 lb-ft of torque (861 Nm). The engine features direct injection, Active Fuel Management and continuously variable valve timing. As a standard, the LT4 comes with a seven-speed manual transmission with Active Rev Match. Optional is the new 8L90 eight-speed paddle-shift automatic transmission, tuned for faster shift-response times. 2015 Corvette Z06 Coupe and Convertible sport technologies introduced on the Corvette Stingray. Such are the SLA-type front and rear suspension design and the third-generation Magnetic Selective Ride Control dampers, adjustable for touring comfort or maximum track performance via the standard Driver Mode Selector. They come as a standard. The smart electronic limited-slip differential, or eLSD, is also standard. It includes a hydraulically actuated clutch capable of infinitely varying clutch engagement.
