While all the enhancements to the 2015 Corvette Stingray coupe and convertible models helped to further advance the car’s perception on the marketplace as a performance vehicle, Chevrolet also unveiled an all-new Z06 model for the 2015 lineup that was more powerful than any production Corvette that had come before it.
At the heart of the 2015 Corvette Z06 was a new LT4 supercharged 6.2L V-8 engine. The LT4 was SAE-certified at 650 horsepower (485 kW) at 6,400 rpm and 650-lb-ft of torque (881 Nm) at 3,600 rpm. This certified performance rating identified the Z06 Corvette as not only the most-powerful production car ever built by General Motors at that time, but also one of the most powerful production cars available in the United States.
