Efficient Performance 2015 Chevrolet Corvette Z06

2015 Chevrolet Corvette Z06

The heart of the 2015 Corvette Z06 is the all-new LT4 6.2L supercharged V-8 engine, expected to deliver an SAE-certified 650 horsepower (485 kW) and 650 lb-ft of torque (881 Nm). 

To balance performance and efficiency, the LT4 leverages the same trio of advanced technologies introduced on the Corvette Stingray: direct injection, Active Fuel Management, or cylinder deactivation, and continuously variable valve timing.

These technologies - combined with the fuel-efficient multi-speed transmissions, aerodynamic design and lightweight construction - help make the new Z06 surprisingly fuel efficient.

To maintain the Z06's mass and performance targets, the LT4 engine was designed with a more-efficient, more-compact supercharger. Even with its integrated supercharger/intercooler assembly mounted in the valley between the cylinder heads, the engine is only about one inch (25 mm) taller than the Corvette Stingray's LT1 engine - while delivering nearly 37 percent more horsepower and 40 percent more torque.

A new 1.7L supercharger spins at up to 20,000 rpm - 5,000 rpm more than the supercharger on the Corvette ZR1's engine. The rotors are smaller in diameter, which contributes to their higher-rpm capability - and enables them to produce power-enhancing boost earlier in the rpm band. That boost is achieved more efficiently via a more direct discharge port that creates less turbulence, reducing heat and speeding airflow into the engine.
