The LS6 6.7L V8: 535 Horsepower and a Record 520 lb-ft

Webb Chevy Oak Lawn | (708) 423-9440 | 9440 S. Cicero Ave, Oak Lawn, IL 60453

How much power does the LS6 make?

535 horsepower and 520 lb-ft of torque. Chevrolet states that 520 lb-ft is the highest figure ever achieved by a naturally aspirated production V8.

Why does displacement matter here?

The LS6 makes its power without forced induction, so response is immediate and linear rather than arriving in a boost surge. A 13.0:1 compression ratio, the highest ever for a Corvette V8, and a new continuously variable oil pump that holds optimal pressure in all conditions are central to that.

What handles the power?

A sculpted wide-body chassis optimized for aerodynamics, an integrated rear spoiler and aggressive wide side air inlets. Magnetic Selective Ride Control 4.0 manages damping, and an available quad center exhaust changes the character of every throttle input.

How do you use the drive modes?

1. Select Tour mode for the street. Tour keeps throttle and shift mapping relaxed for daily driving.
2. Switch to Sport or Track when the road opens. Sharper throttle response and quicker shifts from the 8-speed dual clutch.
3. Use Performance Traction Management on track. PTM manages wheelspin in stages rather than cutting power outright.
4. Record the session. The Performance Data Recorder on 2LT and 3LT logs the lap with live horsepower and torque graphs.
