2027 Chevy Corvette Z06 Delivers 670 HP, Naturally Aspirated 5.5-liter LT6 V8 engine

The 2027 Chevy Corvette Z06 pairs the most powerful naturally aspirated V8 ever offered in a production car with a 2.6-second 0-60 time and a starting price of $121,500. It is built around a 5.5L flat-plane-crank engine borrowed from Corvette’s racing program.

It sits above the Stingray and Grand Sport in the lineup. Unlike the turbocharged ZR1 above it, the Z06 stays naturally aspirated.

This preview breaks down the Z06’s engine, real-world performance numbers, trim pricing, and how it stacks up against the Stingray and the hybrid Grand Sport X that replaced the E-Ray for 2027.

Key Takeaways

• Engine: A 5.5L LT6 naturally aspirated flat-plane-crank V8 producing 670 hp and 460 lb-ft of torque, revving to an 8,600 rpm redline.
• Performance: Chevrolet quotes a 2.6-second 0-60 time and a 10.6-second quarter-mile at 131 mph with the available Z07 Performance Package.
• Top speed: 195 mph with the Z07 Performance Package, which adds carbon fiber aero, carbon-ceramic brakes, and Cup 2 tires.
• Pricing: Starts at $121,500 for the 1LZ trim, climbing to $135,050 for 3LZ before options.
• Lineup position: More power than the Stingray and Grand Sport X, less than the twin-turbo ZR1, and the only trim built around a naturally aspirated racing-derived engine.

What Is the 2027 Corvette Z06’s Engine and Horsepower?

The Z06 is built around the LT6, a 5.5L naturally aspirated V8 with a flat-plane crankshaft, a design that lets the engine rev higher and breathe more freely than a traditional cross-plane V8.

Chevrolet’s engineering team describes it as the most powerful naturally aspirated V8 ever offered in a production car.

Output lands at 670 horsepower and 460 lb-ft of torque, with a redline of 8,600 rpm. That combination puts the Z06 well above the Stingray’s 535 hp but below the twin-turbocharged ZR1’s 1,064 hp, positioning it as the naturally aspirated flagship rather than the outright quickest Corvette.

How Fast Is the 2027 Corvette Z06?

Chevrolet’s official figures list a 2.6-second 0-60 time and a quarter-mile of 10.6 seconds at 131 mph when the Z06 is equipped with the available Z07 Performance Package. GM Authority’s quarter-mile comparison across the 2027 Corvette lineup confirms that figure and shows it trailing only the twin-turbo ZR1 and ZR1X.

However, independent testing tells a different story. Edmunds’ track test of a Z06 equipped with the Z07 Performance Package recorded 0-60 mph in 3.2 seconds and a quarter-mile of 11.1 seconds, well off Chevrolet’s claimed times even with the same package.

That gap matters because it shows up on a fully equipped car, not a stripped-down one. Launch technique, road surface, weather, and testing methods all affect results, so buyers should treat Chevrolet’s figures as best-case numbers rather than everyday expectations.

What Is the 2027 Corvette Z06’s Top Speed?

Top speed reaches 195 mph with the Z07 Performance Package equipped, a figure Chevrolet ties directly to the aerodynamic and braking upgrades that package adds. Without Z07, top speed runs somewhat lower, since the base aero setup is not tuned for sustained high-speed stability in the same way.

Meanwhile, the Stingray above it in the lineup, using the new LS6 6.7L V8, is rated at 200 mph on track, a reminder that top speed and 0-60 numbers do not always move in the same direction between trims.

2027 Corvette Lineup Compared: Power, Torque & Price

Seeing the Z06 next to every other 2027 Corvette model makes its place in the lineup easier to judge. The figures below come directly from Chevrolet’s official Corvette performance report.

Grand Sport X and ZR1X figures combine the V8 engine’s output with the electric drive unit’s output. Starting MSRP excludes destination freight and options, so buyers should confirm exact current pricing with a dealer before budgeting.

2027 Corvette Z06 Trim Levels and Pricing

The Z06 comes in three trim levels, each adding more standard equipment before any options are selected.

Chevrolet’s official Z06 configurator shows an as-tested price of roughly $166,815 once the Z07 Performance Package, carbon fiber accents, and premium interior colorways are added. Buyers cross-shopping trims should budget for the Z07 package separately, since it is what unlocks the Z06’s quoted top speed and quickest acceleration figures. You can have a look at the Corvette 3LZ to get the feel of power and looks.

What Is the 2027 Corvette Z06 Release Date?

The 2027 Corvette Z06 is currently orderable through Chevrolet dealers, with production following the same model-year cadence as the rest of the 2027 Corvette lineup.

Order and build timelines vary by configuration, since the Z07 Performance Package and certain paint or interior colorways can extend build time beyond a standard 1LZ.

LaGrange-area buyers can check current allocation and expected delivery windows directly with a dealer rather than relying on a general release estimate, since Corvette build slots are managed regionally.

What Is the Difference Between the Corvette Z06 and Stingray?

The Stingray uses a new LS6 6.7L naturally aspirated V8 producing 535 hp and 520 lb-ft of torque, favoring low-end torque and muscle-car-inspired character over the Z06’s high-revving racing pedigree. It starts at $71,000, roughly $50,500 below the Z06’s base price.

That said, the Stingray actually edges out the Z06 on outright top speed at 200 mph versus 195 mph, since Chevrolet tuned its aerodynamics differently for each car’s mission.

Buyers who want the highest redline and the most track-focused chassis should lean Z06. Buyers who want strong straight-line torque at a lower price should lean Stingray instead.

Is the Corvette Z06 Better Than the E-Ray?

For 2027, Chevrolet replaced the E-Ray with the Grand Sport X, a hybrid model combining a naturally aspirated V8 with an electric motor for 721 combined horsepower and standard all-wheel drive, starting at $109,700.

Buyers specifically comparing the Z06 against the prior E-Ray concept are effectively comparing it against this new Grand Sport X.

Auto Gallery Chevrolet GMC’s 2025 Corvette E-Ray covers the outgoing E-Ray in detail for shoppers who prefer its 655-hp hybrid AWD setup and 2.5-second 0-60 time.

In addition, remaining E-Ray inventory can still be a strong alternative to the Z06 for buyers who want all-weather traction and hybrid efficiency over the Z06’s naturally aspirated, rear-drive-only character.

Is the 2027 Corvette Z06 Worth the Price?

For buyers who want the highest-revving naturally aspirated V8 Chevrolet has ever built, without stepping up to the ZR1’s turbocharged power and six-figure price jump, the Z06 fills a genuine gap in the lineup.

Its 8,600 rpm redline and racing-derived architecture are not something the Stingray or Grand Sport X can replicate.

Buyers who mainly care about straight-line speed and a lower price may find the Stingray’s 200 mph top speed and $71,000 starting point a better fit.
