2027 Corvette V8 Engines Ranked: LS6, LT6 & LT7

LS6 vs. LT6 vs. LT7: Core Differences Explained

Three V8 engines. Three distinctive personalities. Introducing the 2027 Chevrolet Corvette engine lineup, made up of the LS6, LT6, and LT7.

With each masterfully designed V8 engine offering its own definition of fierce performance, the challenge for drivers is choosing between the three. After all, there’s no such thing as a best Corvette engine because they’re all different, yet each one offers undeniably powerful performance that treats supercar enthusiasts to an unforgettable driving experience.

As Corvette engineer Mike Kociba says, “I truly do believe this is like choosing your favorite flavor of ice cream. Some days I like vanilla, some days I like chocolate. We’re offering that variety, but the bottom line is: they’re all a great choice.”

One thing’s for sure: You’ll feel a rush of adrenaline whenever you start the engine, whether that’s the LS6, LT6, or LT7.

LS6 Engine: All-New & All-in

Chevrolet describes the all-new LS6 engine as one that “leans into that old-school big-displacement punch that Corvette owners know and love.” You’ll find this engine in the 2027 Corvette Stingray, Grand Sport, and Grand Sport X models, serving up jaw-dropping horsepower and torque whether you’re cruising city streets or hitting the track.

In the 2027 Chevrolet Corvette Stingray and 2027 Corvette Grand Sport models, the LS6 small-block V8 engine offers a displacement of 6.7 liters, delivering 535 horsepower and 520 lb-ft of torque.* In the 2027 Chevrolet Corvette Grand Sport X, the LS6 small-block V8 engine is paired with an electric motor, delivering a boost in horsepower and torque: 721 combined horsepower and 665 pound-feet of torque.*

Of this engine, Mike Kociba says, “Torque is our calling card for the LS6. It makes for performance that you can hear and feel. With its displacement and then the 13:1 compression ratio, it hits hard – you hear it, you feel it in your seat and in your ears.”

LT6 Engine: Most Powerful Naturally Aspirated V8

Next in line is the LT6 Gemini V8 engine, found in the 2027 Chevrolet Corvette Z06. With a displacement of 5.5 liters, this V8 engine boasts 670 horsepower and 460 pound-feet of torque* and is the most powerful naturally aspirated V8 engine ever offered in a production car.

Corvette engineer Dustin Gardner describes the LT6 engine as “the highest revving small block we’ve ever done. It’s an emotional engine. That’s what resonates with customers is the free-breathing, naturally aspirated, high engine speed, light, flat plane crank, supercar character.”

The goal was to design a V8 flat-plane crank to spin extremely fast, aiming toward 9000 RPM. The final number was an astonishing 8600 RPM.

“The LT6 and the Z06 are definitely the most track-focused Corvettes we have,” says Dustin Gardner. “It’s supposed to feel like the lightest, the most pure. With that engine, it really is the track scalpel choice.”

LT7 Engine: Twin-Turbo Power King

If you want ultimate power, the LT7 Gemini V8 engine takes Chevrolet Corvette performance to the next level. You’ll find this engine in both the 2027 Chevrolet Corvette ZR1 and the 2027 Chevrolet Corvette ZR1X. 

Featuring twin turbochargers and a displacement of 5.5 liters, this engine dazzles with 1064 horsepower and 828 pound-feet of torque* in the ZR1 and 1250 combined horsepower and 973 pound-feet of torque* in the ZR1X.

Of the LT7, Dustin Gardner says, “If you want most of the LT6’s character, and you just want no-compromise torque and power that’s off the charts, then you go to the twin-turbo variant of the two, the LT7. It comes with mind-bending power and torque.”

The LT7 engine’s performance satisfies drivers who crave maximum power and extreme thrills.
