Producing 670 horsepower and 460 pound-feet of torque from the mid-mounted, naturally aspirated 5.5L V8 LT6 gasoline engine, the up-and-coming 2023 Corvette Z06 is a real rocket ship. Funny enough, General Motors actually added 54 rocket ship “easter eggs” around the 2023 Corvette Z06’s engine bay and powerplant.
Per a recent report from Ward’s Auto, the rocket ship easter eggs can be found on the 5.5L V8 LT6 engine block, valve covers, and various other components. The rocket ships give a nod to the NASA astronauts of the moonshot era, who, as most Corvette fans know, were huge fans of the America’s sports car.
Further rocket ship connections can be found in the name given to the internal development project that gave birth to the LT6 engine, specifically GM’s Project Gemini. Project Gemini was also NASA’s second human spaceflight program in the ‘60s, which helped to pave the way to the Apollo missions that put astronauts on the Moon.
The 5.5L V8 LT6 gasoline engine is framed as the most powerful naturally aspirated V8 engine ever equipped in a production car, infusing the 2023 Corvette Z06 with some real race car stuff. Highlights include an aluminum block, lightweight flat-plane crankshaft, CNC-ported intake and combustion chambers, forged aluminum pistons, forged titanium connecting rods, dry-sump lubrication, and unique water cooling jackets, among several other high-tech, performance-boosting features.
Redline is set at a head-spinning 8,600 rpm, blessing the 2023 Corvette Z06 with a decidedly exotic exhaust note, as GM Authority covered previously. In fact, General Motors benchmarked the new Z06 against European makes like Ferrari, Porsche, and McLaren.
Output is sent exclusively to the rear axle by way of an eight-speed dual-clutch automatic transmission and eLSD, with Z06-specific wheels and tires onboard to put it to the pavement. The 2023 Corvette Z06 also features Magnetic Ride Control 4.0 suspension.
Production will take place at the GM Bowling Green assembly facility in Kentucky.
