DETROIT – Chevrolet currently introduced a many track-capable Corvette in a brand’s story – a 2015 Corvette Z06. It stretches a opening pouch for Corvette with rare levels of aerodynamic downforce, during slightest 625 horsepower from an all-new supercharged engine, and an all-new, high-performance eight-speed involuntary delivery – all building on a modernized motorist technologies introduced on a Corvette Stingray.

“The new Z06 delivers levels of performance, record and settlement that opposition a many outlandish supercars in a world,” pronounced Mark Reuss, president, General Motors North America. “And a Z06 leverages a engineering imagination of GM, charity a choice of dual world-class transmissions, supercar opening though supercar fuel expenditure and technologies that make it easier to entirely suffer a implausible knowledge of pushing it.”

The 2015 indication is a initial Corvette Z06 to offer a supercharged engine, an involuntary delivery and, interjection to a stronger aluminum frame, a removable roof panel. The new, supercharged 6.2L engine is approaching to broach during slightest 625 horsepower (466 kW), and can be matched with possibly a seven-speed primer or an all-new, high-performance eight-speed involuntary delivery with paddle shifters for primer control. The aluminum support carries over from a Corvette Stingray and will be used radically unvaried for a Corvette Racing C7.R.

A track-focused Z07 Performance Package adds singular components for loyal aerodynamic downforce, Michelin Pilot Super Sport Cup tires for extended grip, and Brembo CO ceramic-matrix stop rotors that urge braking opening and minister to incomparable doing by reduced unsprung weight. Although growth contrast is ongoing, a Z07 package has already permitted some of a fastest path times ever for a Corvette, leading even a ZR1.

“The Corvette Z06 is a good instance of a record send between racing and prolongation Corvettes,” pronounced Tadge Juechter, Corvette arch engineer. “First, we took what we schooled on a Corvette Racing C6.R and practical that to a all-new Corvette Stingray. Then, regulating a Stingray as a foundation, a Z06 and C7.R were grown to pull a pouch of opening on a travel and a track.”

Supercharged, fit performance

The heart of a 2015 Corvette Z06 is a all-new LT4 6.2L supercharged V-8 engine, approaching to broach an estimated 625 horsepower (466 kW) and 635 lb-ft of torque (861 Nm). To change opening and efficiency, a LT4 leverages a same contingent of modernized technologies introduced on a Corvette Stingray: Direct injection, Active Fuel Management, or cylinder deactivation, and invariably non-static valve timing.

These technologies – total with a fuel-efficient multi-speed transmissions, aerodynamic settlement and lightweight construction – assistance make a new Z06 surprisingly fuel efficient.

“The supercharged LT4 engine delivers a biggest change of opening and potency ever in a Corvette,” pronounced John Rydzewski, partner arch operative for Small-Block engines. “It is one of a world’s usually supercharged engines to incorporate cylinder deactivation technology, enabling it to journey good on a highway with reduced fuel consumption, though offer some-more than 600 horsepower whenever a motorist calls adult a extensive energy reserve.”

To say a Z06’s mass and opening targets, a LT4 engine was designed with a more-efficient, more-compact supercharger. Even with a integrated supercharger/intercooler public mounted in a hollow between a cylinder heads, a engine is usually about one in. (25 mm) taller than a Corvette Stingray’s LT1 engine – while delivering scarcely 37 percent some-more horsepower and 40 percent some-more torque.

The new 1.7L Eaton R1740 TVS supercharger spins during adult to 20,000 rpm – 5,000 rpm some-more than a supercharger on a Corvette ZR1’s LS9. The rotors are shorter in length, too, that contributes to their higher-rpm capability – and enables them to get adult to speed quicker, producing power-enhancing boost progressing in a rpm band. That boost is achieved some-more efficiently, interjection to a new, some-more approach liberate pier that creates rebate turbulence, shortening feverishness and speeding airflow into a engine. 

The LT4 engine also has several singular facilities designed to support a aloft outlay and a incomparable cylinder pressures combined by forced induction, including:

  • Rotocast A356T6 aluminum cylinder heads that are stronger and hoop feverishness improved than compulsory heads
  • Lightweight titanium intake valves and machined joining rods for reduced reciprocating mass
  • High 10.0:1 application ratio – for a forced-induction engine – enhances opening and potency and is enabled by approach injection
  • Forged aluminum pistons with unique, stronger structure to safeguard strength underneath high cylinder pressures
  • Stainless steel empty headers and an aluminum balancer that are lighter than their LT1 counterparts
  • Standard dry-sump oiling complement with incomparable cooler ability than Z51; used with dual-pressure-control oil pump.

The LT4 will be built in Tonawanda, N.Y., and during a new Performance Build Center in Bowling Green, Ky.

Eight speeds, no waiting

The supercharged LT4 is offering with a customary seven-speed primer delivery with Active Rev Match, or an all-new 8L90 eight-speed paddle-shift involuntary delivery designed to raise both opening and efficiency.

“Unlike many ultra-performance cars, a Corvette Z06 offers business a choice between dual transmissions to fit their pushing styles,” pronounced Juechter. “The seven-speed gives a motorist a control of a loyal three-pedal primer delivery with ideal shifts enabled by Active Rev Matching. The new eight-speed involuntary offers drivers a comfort and drivability of a loyal involuntary transmission, as good as lightning-fast shifts and primer control for lane driving.”

The seven-speed primer incorporates rev-matching record for upshifts and downshifts. This driver-selectable underline can be simply intent or unattached around paddles on a steering wheel. The seven-speed is used with a new dual-mass flywheel and dual-disc clutch, that broach incomparable change peculiarity and feel by revoke inertia.

The eight-speed involuntary is tuned for world-class shift-response times, and smaller stairs between gears keep a LT4 within a honeyed mark of a rpm band, creation a many of a outlay of a supercharged engine for refreshing opening and incomparable efficiency.

For opening driving, a delivery offers full primer control around steering circle paddles, and singular algorithms to broach change opening that rivals a dual-clutch/semi-automatic transmissions found in many supercars – though with a fibre and excellence that comes with a compulsory involuntary propitious with a torque converter.

In fact, a 8L90’s controller analyzes and executes commands 160 times per second, and wide-open stifle upshifts are executed adult to eight-hundredths of a second quicker than those of a dual-clutch delivery offering in a Porsche 911.

“There’s no trade-off in drivability with a new 8L90 eight-speed involuntary delivery – it was designed to broach opening on customary with dual-clutch designs, though though sacrificing refinement,” pronounced Bill Goodrich, partner arch operative for eight-speed involuntary transmissions. “It is also a highest-capacity involuntary delivery ever offering in a Chevrolet car.”

Featuring 4 gearsets and 5 clutches, artistic wrapping enables a GM-developed eight-speed involuntary to fit a same space as a six-speed involuntary used in a Corvette Stingray. Extensive use of aluminum and magnesium make it some-more than 8 pounds (4 kg) lighter than a six-speed. Along with settlement facilities that revoke friction, a 8L90 is approaching to minister adult to 5-percent incomparable efficiency, when compared with a six-speed automatic.

The eight-speed involuntary will be built during GM’s Toledo, Ohio, delivery facility.

Designed for downforce

The opening targets of a Z06 also acted a plea for a settlement team, that had to emanate a renowned settlement that also contributed to augmenting capabilities.

“Practically each extraneous change served a organic purpose, as this savage indispensable some-more of everything,” pronounced Tom Peters, Corvette settlement director, “The flared fenders accommodate larger, wider wheels and tires for some-more grip. The incomparable vents yield some-more cooling atmosphere to a engine, brakes, delivery and differential for augmenting lane capability. The some-more assertive aerodynamic package generates loyal downforce for some-more cornering hold and high-speed stability.”

The settlement changes began not with a extraneous panels, though a tires.

To broach a levels of hold indispensable for a Z06’s opening targets, a Z06 was propitious with incomparable Michelin tires (Pilot Super Sport tires for a Z06; Sport Cup 2 tires with a Z07 package). The P285/30ZR19 front tires are 1.5 inches wider than a tires on a Stingray, while a 335/25ZR20 back tires are dual inches wider.

To cover a wider tire tread, a fenders of a Z06 were extended by 2.2 inches (56 mm) during a front, and 3.15 inches (80 mm) during a rear. These extensions give a Corvette Z06 a wider, revoke coming offer emphasized by a singular back fascia. It incorporates a same taillamp assemblies as a Stingray, though on a Z06 a taillamps are pushed approximately 3 inches over apart, toward to edges of a body.

The tires are mounted on lightweight, spin-cast aluminum wheels that are also wider than a Stingray (19 x 10 inches in front and 20 x 12 inches in a rear). Their open, ultralight settlement showcases a large Brembo brakes, that are partial of a settlement aesthetic:

  • The Z06 facilities 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 bound 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) CO ceramic-matrix stop rotors for unchanging opening path after lap, and collectively save 23 pounds over a customary Z06 rotors.

To strap a cornering and braking hold afforded by a incomparable tires and brakes, a extraneous of a Corvette Z06 is tailored to furnish aerodynamic downforce that presses a tires to a belligerent during high speeds.

The Z06 will offer three, augmenting levels of aerodynamic downforce:

  • The customary Z06 facilities a front splitter, spats around a front circle openings, a singular carbon-fiber hood with a incomparable vent, and a back spoiler from a Corvette Stingray’s Z51 Performance Package
  • An permitted carbon-fiber aero package – in possibly black or a manifest carbon-fiber finish – adds a CO fiber front splitter with aviation-style winglets, CO fiber rocker panels, and a incomparable back spoiler with a bound wickerbill – a small, straight add-on during a corner of a spoiler that significantly increases downforce
  • The permitted Z07 package supplement incomparable winglets to a front splitter, along with an adjustable, see-through centre territory on a back spoiler for lane use. With this package, a Corvette Z06 delivers a many aerodynamic downforce of any prolongation automobile that GM has tested.

The extraneous settlement also reflects a augmenting cooling compulsory for a new Corvette Z06. For example, a filigree settlement on a front fascia was painstakingly designed to broach a many probable airflow to a supercharger’s intercooler feverishness exchanger, so many that a filigree griddle leads some-more atmosphere into a engine brook than if a grille was removed.

The singular grille also facilities dedicated brake-cooling intakes and wider grille outlets on a bottom offer as atmosphere diffusers. The grille is complemented with a incomparable hood vent, that vents prohibited atmosphere from a engine cell and contributes to downforce by permitting atmosphere driven by a grille to exit by a hood rather than being forced underneath a car, that could emanate lift.

Additional cooling elements embody incomparable front buffer vents and singular atmosphere blades over a inlets on a back fenders, that force about 50 percent some-more atmosphere into a cooling ducts for a delivery and differential coolers than those on a Stingray. To cope with a additional airflow, a Z06 has also has incomparable rear-fascia openings than a Stingray.

Standard front and back brake-cooling ducts, including Z06-signature back ducts integrated in front of a back buffer openings, are also partial of a organic settlement changes.

Inside, a Corvette Z06 is renowned from a Corvette Stingray by singular colour schemes that stress a driver-focused cockpit, and a unique, flat-bottomed steering wheel.

Like a Stingray, a Z06 will be offering with dual seating choices: a GT seat, for all-around comfort, and a Competition Sport chair with some-more assertive side bolstering, that provides incomparable support on a track. The support structure for both seats is done of magnesium, for incomparable strength and rebate weight than allied steel frames. They’re also some-more rigid, contributing to a extended feeling of support during opening driving.

The Z06 also advantages from interior sum designed for high-performance driving, initial introduced on a Stingray, including a steel-reinforced squeeze bar on a centre console for a newcomer and soft-touch materials on a corner of a console, where a motorist naturally braces during high-load cornering.

The performance-supporting elements inside a new Corvette Z06 are complemented by rare courtesy to fact and build quality. All models underline a entirely wrapped interior, where each aspect is lonesome with premium, soft-touch materials. Available materials, depending on a trim level, embody Napa leather, aluminum, CO fiber and micro-suede.

Track-proven technologies

The 2015 Corvette Z06 leverages a technologies introduced on a Corvette Stingray, including a vital use of lightweight materials and modernized motorist technologies, with singular facilities and calibrations tailored for a capabilities.

“Our goal with a seventh-generation Corvette was to make a opening levels some-more accessible, enabling drivers to feat each pound-foot of torque, each “g” of hold and each bruise of downforce,” pronounced Juechter. “It’s a truth we introduced with a 460-horsepower Corvette Stingray – and one that’s even some-more applicable with an estimated 625 horsepower during your beck and call.”

For a initial time ever, a Corvette Z06’s aluminum support will be constructed in-house during General Motors’ Bowling Green public plant. It’s a same robust, lightweight support used on a Corvette Stingray and it will be used radically unvaried for a C7.R competition cars.

The stiffer settlement of a aluminum support allows a Corvette Z06 to be offering with a removable roof row for a initial time. With a lightweight, CO fiber roof row removed, a new Corvette Z06 offers 20 percent some-more constructional acerbity than a prior model’s fixed-roof design. It is 60 percent stiffer than a prior indication with a roof row installed.

The new Z06 retains a SLA-type front and back cessation settlement of a Corvette Stingray though singly calibrated for a aloft opening threshold. The third-generation Magnetic Selective Ride Control dampers are customary on Z06. They can be practiced for furloughed comfort or limit lane opening around a customary Driver Mode Selector.

Like a Stingray, a Driver Mode Selector tailors adult to a dozen facilities of a Z06 to fit a driver’s environment, including:

  • Launch control: Available in Track mode for primer and involuntary transmissions, providing limit off-the-line acceleration
  • Active doing (StabiliTrak electronic fortitude control): A “competitive” environment is permitted in Track mode and is some-more matched for on-track conditions. It can also be disabled, giving a motorist finish control
  • Traction control: Weather mode tailors traction control and engine torque for pushing in severe conditions
  • Performance Traction Management: Available in Track mode and offers 5 settings of torque rebate and stop involvement for lane driving
  • Electronic Limited Slip Differential: Adjusts a rate during that a singular trip engages, to change between steering response and fortitude in opposite pushing conditions with some-more assertive opening in Sport and Track modes.

The intelligent electronic limited-slip differential, or eLSD, is customary on a Z06 to make a many of a torque separate between a back wheels. The complement facilities a hydraulically actuated purchase that can forever change purchase rendezvous and can respond from open to full rendezvous in tenths of a second. It shifts torque formed on a singular algorithm that factors in automobile speed, steering submit and stifle position to urge steering feel, doing change and traction.

The eLSD is entirely integrated with Electronic Stability Control and Performance Traction Management systems. Its calibrations change among 3 modes, formed on a Drive Mode Selector setting:

  • Mode 1 is a default environment for normal pushing and emphasizes automobile stability
  • Mode 2 is intent when electronic fortitude control is incited off in a Sport or Track modes. This calibration enables some-more nimble turn-in and traction while accelerating out of a corner
  • Mode 3 is automatically comparison when Performance Traction Management is engaged. This calibration has a same duty as Mode 2, though is fine-tuned to work with Performance Traction Management.

The new Corvette Z06 will be permitted in early 2015. Performance information and pricing will be announced closer to a start of production.
