Z06 Detail

Every lane is victory lane.
Le Mans. Sebring. Daytona. Detroit. All conquered by the C8.R race car in its pursuit of racing glory. And now, that same technology comes to the streets with the all-new Corvette Z06.
Purpose-built to dominate the track, its flat-plane V8 is capable of 670 horsepower making it the most powerful naturally aspirated V8 in production and will take you from 0 to 60† in 2.6 seconds.

Sounds like a win.
Its 670 horsepower makes it the most powerful naturally-aspirated V8 in production. A testament to unrelenting craftsmanship, this hand-built engine features an all-new flat plane architecture that gives it a signature growl. Strike fear in your competition as it hits a redline of 8600 RPM – 2000 RPM higher than Stingray.

4.4 in./111.76 mm bore centers with 4.1 in./104.25 mm bore help continue a rich heritage of Chevrolet small block engines.
Continuously variable pressure delivery coupled with six scavenge stages helps ensure optimal oil delivery for the ultimate in track capability.

Superb stopping power.
A car this capable requires some serious braking ability, and its standard 6-piston front/4-piston rear brakes are designed to give you just that.
Available carbon ceramic brakes provide state-of-the-art braking performance for track demands.

Track born meets the streets.
Create your own legend with the legendary Z07 Performance Package, available on Z06. It provides added aero prowess along with standard carbon ceramic brakes and Michelin® Pilot Sport® Cup 2 tires.
Available carbon-fiber wheels provide an unsprung weight savings of 41 lbs., because every gram counts on the path to racing perfection.

Sculpted to soar.
The striking exterior of Z06 features wider fenders, quarter panels and fascias than Stingray, resulting in a form as commanding as it is functional. The standard ground effects and spoiler optimize aerodynamic drag and powertrain cooling efficiency. Replaceable spoiler wickerbills, rear brake cooling ducts, removeable front fascia panel and front underwing stall gurneys increase downforce, keeping the Z06 poised and planted as you round the track.

Chevy’s mid-engine Corvette revolution continues with today’s official reveal of the 2023 Corvette Z06, a precision tool for the track as it is being described. Its body is wider and longer, it’s more powerful than expected, and did we mention that sound from the 5.5L flat-plane crank V8?
“The new Corvette Z06 defines the American supercar,” said General Motors President Mark Reuss. “It builds on the distinctive design and groundbreaking dynamics introduced with the mid-engine Corvette and elevates them to deliver refined but uncompromising track capability with world-class performance.”

America’s newest supercar is powered by Chevy’s revolutionary LT6, a dual overhead cam 5.5-liter V8 which makes 670 horsepower and 460 lb-ft of torque at 6300 RPM.

As racing and performance enthusiasts love naturally aspirated engines for their responsiveness and trackability, the small-block LT6 was a clean-sheet design with the goal to create a naturally aspirated powerplant the would exceed the power of any naturally aspirated production V8 engine ever made. To accomplish that goal, Chevy engineers turned to a flat-plane crankshaft design, which combined with the LT6’s short stroke enables the engine to redline at 8,600 RPM.

The LT6 also features forged aluminum pistons and forged titanium connecting rods for low mass and high strength, and a six-stage dry-sump oiling system. It also looks like no other Corvette engine before with an all-new active split-intake manifold with 87mm throttle bodies and distinctive Edge Red camshaft covers. A carbon fiber engine cover will be sold separately as an accessory.

A version of the LT6 has powered Corvette Racing’s C8.R racers since 2019 and the direct transfer of technology from racing to street has never been more evident than now with the cars sharing the chassis, similar engine architecture, and exterior proportions. In fact, the C8.R has been described as the Z06 hiding in plain sight.
The LT6 will be hand assembled by master engine builders at the Performance Build Center inside the Bowling Green Assembly Plant. Like the previous engine builds from the PBC, each engine features a plaque on the intake manifold with the signature of the engine builder who assembled it from start to finish.

With racing fused in its DNA, the Z06 was designed to exploit its track capabilities in all areas. Chevy engineers added another heat exchanger in the center of the front fascia to pull in additional cooling, just like the C8.R race cars for the engine, brakes, and transaxle. The wider rear fascia also allows for larger air intakes required for cooling the Z06. In fact, the Z06 takes in 50% more air for cooling than the C8 Stingray.

The wide body design gives the Z06 a wider stance that is 3.6 inches wider than the C8 Stingray. This allows for the use of wider tires and wheels, with the Z06 offering 20×10-inch front wheels with 275/30ZR20 tires and 21×13-inch rear wheels that are sized for 345/25ZR21 tires. Michelin Pilot Sport 4S tires are standard with the Sport Cup 2R tires available with the Z07 Performance Package.

Three levels of increasing aerodynamic support will be offered for the Z06. The standard Z06 features a front splitter and a unique rear spoiler, which includes an installable fixed wickerbill on the edges that provides 365 pounds of downforce at 186 mph
. Also offered is the available carbon fiber aero package that adds a larger front splitter, front corner dive planes, and a pedestal-mounted rear wing and under body aero strakes for the maximum track capable downforce and maneuverability. With the carbon fiber aero pack, the 2023 Corvette Z06’s downforce is rated at 734 pounds at 186 mph. It’s the most downforce offered ever on a Corvette.

“Virtually every component that distinguishes the Z06 was developed to support or enhance its capability,” said Corvette Chief Engineer Tadge Juechter. “By leveraging the mid-engine architecture’s inherent advantages, we are able to achieve six percent more downforce than a seventh-gen ZR1 at eight percent lower drag.”

Responsibility for stopping the Z06 will once again fall to Brembo Brakes. The standard Z06 features Brembo’s 14-6 inch diameter front and 15-inch diameter rear rotors, and unlike the Stingray which has four-piston front calipers, the Z06 will be utilizing a six-piston front calipers. The Z07 Performance Package allows for even greater stopping power with carbon ceramic rotors that include 15.7-inch diameter front rotors and 15-4 inch diameter rear rotors.
The carbon ceramic brakes are a free-flow option that can be added to the standard Z06 without having to order the Z07 Performance Package.

The Z07 Performance package features include:
• Carbon Fiber aero package (larger front splitter and dive planes, rear wing, and underbody strakes)
• Unique FE7 Suspension with specific Magnetic Ride Control 4.0 calibrations
• Michelin Sport Cup 2 R ZP tires developed specifically for the Z06
• Available Carbon Fiber wheels that deliver a 41-pound weight reduction in unsprung mass
• Brembo Carbon Ceramic brake system

The 2023 Corvette Z06 retains the SLA-type double wishbone front and rear suspension that was first featured on the C8 Corvette Stingray, but it has been uniquely tuned for its higher performance capabilities. Magnetic Ride Control 4.0 comes standard on the Z06 with drivers being able to adjust the suspension from touring comfort to maximizing track performance with the Driver Mode selector.
Like the Stingray, the Z06 can be tailored to the driving environment which includes Active Handling, Traction Control, Performance Traction Management, and more. The 8-speed automatic dual-clutch transmission has also been customized with a shorter 5.56 final drive ratio for enhancing the Z06’s acceleration capabilities. The Corvette Z06 is able to sprint from 0-60 mph in 2.6 seconds!

On the skid pad, the Corvette Z06 with the Z07 Performance Package is capable of 1.22 g of road hugging grip. The Z06 is so stiff that its track-capable versions are offered on both the Coupe and Convertible with no difference in the suspension calibrations.
Also unique to the Z06 among Corvettes is the exhaust note.
The LT6 includes a “four-into-two-into-one” stainless-steel headers and centered “floating” exhaust bezels which are designed to maximize the precise tuning and sound of the exhaust note. Chevy engineers customized and tuned the sound of the engine and exhaust note for two years to find the perfect note for the new Z06. Customers will be able to choose between black or chrome tips.

The 2023 Corvette Z06’s performance and good looks are also matched by the quality of materials used in the cabin.
New for the Z06 is an available carbon fiber wrapped steering wheels, shift paddles, and a new level 2 carbon fiber interior package. A new stealth aluminum trim option takes all the bright aluminum interior trim that includes the speaker and door bezels and makes them darker. Buyers can also take advantage of a new full-trimmed interior in Adrenaline Red that includes red carpet as well.

The Z06 also has the most personalization options available when selecting the choice of wheels, colors, and trim items.
Customers will be able to choose between:

• Twelve available exterior colors
• Seven available wheel packages include five finishes on the standard forged aluminum wheels and available carbon fiber wheels
• Seven interior colors with the ability to expand it to thousands of combinations
• Three seat choices and six seatbelt colors
• Two interior carbon fiber trim packages, plus a new Stealth Aluminum trim option
• Six available brake caliper colors
Chevrolet will offer pricing information for the new 2023 Corvette Z06 at a future date.
The Z06 will begin production in the summer of 2022, and it will be offered in Left and Right-hand Drive configurations.

Chevy on 10/26/21 unveiled the track-focused model of its mid-engine Corvette supercar, the C8 Z06.

Sporting the most powerful, normally-aspirated engine ever made, the Z06’s bespoke, 5.5-liter, dual-overhead-cam V-8 LT6) boasts a gain of 670 horsepower to 175 more than the standard, mid-engine Corvette Stingray, and 20 more than the last-gen Z06 and its supercharged V-8 LT4 engine.

The Z06 achieves its outrageous output using a free-spinning, flat-plane crank and 8,600-rpm redline technology usually associated with Ferrari supercars costing three times as much.
The spine-tingling shriek of the Z06 will be familiar to race car fans who have heard the engine propel the Corvette C8.R to seven wins and an IMSA sports car championship since its introduction in 2020.

"It's been hiding in plain sight. (We were) developing the heart of the beast," smiled Corvette Executive Chief Engineer Tadge Juechter as we circled a menacing, pumpkin-colored Z06 under GM’s Warren design center dome a week before Halloween.

To realize the full potential of the ferocious LT6 engine, Juechter and his guys had to make significant upgrades to the nimble Corvette C8,
which at $62,195 has sold like hotcakes with 495 horsepower and European-supercar good looks.
Stingrays are trading at some dealerships at $30,000-plus above sticker price.
Though pricing for the 2023 Z06 won’t be announced until closer to its summer 2022 release, expect it to start around $20,000 over a Z51 sticker which will be equipped with the must-have Z07 handling package

A huge, carbon-fiber rear wing juts from the rear chassis like a scorpion’s tail, putting over 730 pounds of down force. Fang-like dive planes pepper the face below the Corvette familiar, brooding headlights. Contrary to past Z06 upgrades, the ‘23 model shares only hood, hatchback, doors, and roof with the base Stingray.
Two features instantly distinguish the Z06 from the standard model.
The first: larger side intakes, shaped appropriately like a stingray’s tale.
“Performance aspirations force the car to look different,” said Juechter. “(It’s) enabled by the tires. That width drives the rear quarter panel out and makes the duct opening bigger, and the engine needs that.”
To harness the power of the LT6 mill, Michelin PS4 tires have been widened 1.3 inches over the already fat, 12-inch standard tire.
Softer compound Michelin Cup 2s are also available. The big rubber forced a 3-inch widening of the rear bodywork.

The second signature feature is the center-mounted quad tailpipes out back (the base V-8 splits its quad pipes into pairs on either corner of the rear diffuser). Juechter said the change was necessary in part to better channel the high-revving V-8's sound not just for exterior presence, but also for the enjoyment of the driver riding in the forward cabin.

The new, bigger fascia is more pronounced, holds three heat exchangers (the standard Stingray has two) to cool the temps within.
“We start with the Stingray, then amp everything up.
This is the first time we’ve done a full perimeter” on a Z06, said Juechter, referring to the exterior bodywork. “This enables us to do a better job on aerodynamics, package more coolers. We wanted this to be extremely capable on track.”

Juechter said Chevy’s new track weapon significantly outruns the previous-gen Z06 and can go wheel-to-wheel with the winged, $122k, 755-horse ZR1 C7 uber-'Vette.
With the Z07 package, the Z06 makes 734 pounds of downforce at 186 mph, the most of any Corvette ever.
On the skid pad, Juechter says the Z06 will pull a neck-straining 1.22 g-loads compared to ZR1’s 1.2.
At 186 mph, it boasts 6% more down force, 8% less drag.

The standard Stingray’s high-tech interior already shames most European exotics, and the Z06 doesn’t fiddle with the formula.
The instrument displays are digital, configurable. Wireless Apple CarPlay and Android Auto are standard, so you can find the nearest racetrack.
The square steering wheel is festooned with useful buttons, including Z-mode, so you can instantly transform the car from interstate comfort to nuclear weapon should any muscle-car peer dare to challenge.

In keeping with its expected $20k premium over the Z51 based C8, Z06 has turned up the volume on materials.
The steering wheel can be trimmed in carbon fiber, as can the entire center console.
All this performance is still available in both coupe & removable hard-top convertible configurations, trunk and front trunk storage are uncompromised.
The coupe version allow you to gaze into the engine chamber at the 5.5-liter engine.

Not only does its high-pitched note sound like a Ferrari, its output is well north of the $300k Ferrari 458 Special V-8's 597 horsepower.
More comparisons?

The production LT6 engine has 170 more horsepower than the C8.R race engine due to Balance of Performance restraints placed on the race car to keep it from running away from class competitors.

“We have a lot more power than the race car,” laughed Juechter, who also points to the sophisticated, standard, magnetic dampers on the Z06 also prohibited in racing.
The race car and production Corvette C8 were developed in parallel, ensuring a direct technology transfer from track to street.
The C8.R shined in its first year of IMSA sports car competition, capturing six victories and winning the GT manufacturer's title.

“The new Corvette Z06 defines the American supercar,” said GM President Mark Reuss, himself a race-licensed driver.
“It builds on the groundbreaking dynamics introduced with the mid-engine Corvette and elevates them, too.”

It will be built in Bowling Green, Kentucky, in left-and-right-hand drive configurations, the latter for overseas markets.
“Ex-Corvette racer Oliver Gavin has been doing development work at the Nürburgring,” said Juechter, referring to Germany’s racetrack.
“(We want) to make sure the car is competent on track and on the Autobahn, which is why we go there. We want to sell this car in Europe.”

The LT6

The new 5.5-liter flat-plane crank LT6 V8 has a bore of 4.104 inches and a stroke of 3.150 inches.
The block is manufactured from A319-T7 sand-cast aluminum and features pressed-in iron cylinder liners and four-bolt main bearing caps with A356 T6 cast aluminum heads.

The DOHC 32-valve mill is capable of 670 horsepower at 8,400 RPM and a max torque of 460 lb-ft at 6,300 RPM.
The Tremec 8-speed dual-clutch transmission is designed with a shorter 5.56:1 final drive for the Z06.

Suspension Setup

The suspension setup at the front and rear is a short/long-arm double wishbone system.
There are forged aluminum upper and cast aluminum L-shaped lower control arms and monotube shock absorbers at work.
The Magnetic Selective Ride Control 4.0 is an option.
The Z07 performance package gets its own specially tuned version of the Magnetic Ride Control system.


The Z06 comes with new Brembo brakes at all four corners.
The front wheels are equipped with 6-piston calipers and 14.6-inch rotors. At the rear, there are 4-piston brakes with 15-inch rotors.
The Z07 package brings in carbon-ceramic brakes measuring 15.7-inches and 15.5-inches at the front and rear respectively.

Wheel and Tire Options

The first mid-engine Z06 features a staggered wheel setup, with the front wheels measuring 20 by 10 inches and the rear wheels 21 by 13.
The carbon fiber wheels shown in the image above are available with the Z07 package as well.
The standard tires for the Z06 are Michelin Pilot Sport 4S ZPs. Though with the Z07, Michelin Sport Cup 2 R ZP tires are also an option.

Exterior Dimensions

Gaining 3.6 inches of width in comparison to the Stingray, the Z06 models will measure 79.7 inches wide.
The track measurements are 66.3 and 66.1 inches for the front and rear, respectively.
The overall length of the standard Z06 comes in at 184.6 inches, while the carbon fiber ground effects bring the total up to 185.9.
The wheelbase is 107.2 inches and the overall height is 48.6 inches.
With the Z07 package and lightweight wheels, the car weighs in at 3,434 lbs.

Interior and Cargo

The interior space is not changed from the base trim.
Here we get 37.9 inches of headroom, 42.8 inches of legroom, 54.4 inches of shoulder room, and 52 inches of front hip room.
The cargo space remains the same as the Stingray as well, with 12.6 cubic inches of capacity.
