The New LS6 6.7L V8 in the 2027 Corvette: 535 HP of Naturally Aspirated Power
The 2027 Corvette’s new LS6 is a 6.7L naturally aspirated V8 producing 535 horsepower and 520 lb-ft of torque. It features a 13.0:1 compression ratio — the highest ever for a Corvette V8 — a tunnel-ram intake with high-velocity ports, and a new continuously variable oil pump, paired with an 8-speed dual-clutch transmission. It’s standard on the 2027 Stingray, Grand Sport, and Grand Sport X.
For 2027, the volume models of the Corvette lineup get a brand-new heart: the LS6 6.7L V8. In an era of turbos and hybrids, Chevrolet built a bigger, higher-revving naturally aspirated V8 — and enthusiasts are paying attention. Here’s what makes it special, the real numbers, and which models get it.
The Numbers
| Spec | LS6 6.7L V8 |
|---|---|
| Configuration | Naturally aspirated V8 |
| Displacement | 6.7 liters |
| Horsepower | 535 hp |
| Torque | 520 lb-ft |
| Compression | 13.0:1 (highest ever for a Corvette V8) |
| Transmission | 8-speed dual-clutch (DCT) |
535 horsepower from a naturally aspirated engine is a serious number, and the 13.0:1 compression ratio — the highest Chevrolet has ever put in a Corvette V8 — is the headline engineering achievement. High compression means more power extracted from each combustion event, and it’s a big part of how the LS6 makes its output without forced induction.
The Engineering Behind It
Beyond the big compression number, the LS6 is full of clever details. It uses a 95mm throttle body and a tunnel-ram intake with high-velocity ports to move air efficiently at high rpm, and a new continuously variable oil pump that maintains optimal oil pressure in all conditions — important for a high-performance engine that might see both street and track duty. A long 100mm stroke helps build the torque that makes it tractable on the road, not just at the top of the tach. The result, in Chevrolet’s words, is immediate, linear response with a composed, confident character.
How It Sounds
A naturally aspirated V8 has a sound that turbos simply can’t replicate, and for 2027 Chevrolet leans into it: performance exhaust is now standard across the lineup, with an aggressive note that changes with the driver mode you select. An available quad center-exit exhaust takes it further. For a lot of buyers, that NA V8 soundtrack is the entire point — and the LS6 delivers it.
Which Models Get the LS6
The LS6 6.7L V8 is standard on three 2027 Corvettes: the Stingray, the Grand Sport, and the all-wheel-drive Grand Sport X (where it combines with an electric front motor for 721 total horsepower). The higher models use different engines — the Z06’s flat-plane 5.5L, the ZR1’s twin-turbo 5.5L — but for the heart of the lineup, the LS6 is the new standard-bearer. Available engine covers come in Black, Red, Silver, or Blue.
Enthusiasts get genuinely excited about this engine — a brand-new naturally aspirated V8 in 2027 is a rare and special thing. When folks hear one run, the decision kind of makes itself. We’ll order you a Corvette with the LS6 — most trims below sticker — and let the engine do the talking.
If a big, naturally aspirated V8 is what stirs your soul, the new LS6 is reason enough to want a 2027 Stingray or Grand Sport — 535 hp, record compression, and a sound no turbo can match. Carter prices most Corvette trims below MSRP and can order your exact build.
