The new 2023 Corvette Z06 made its official debut this week, arriving with a long list of impressive equipment – including the most powerful naturally aspirated V8 engine ever conceived for a production car.
While we’ve already covered the 2023 Corvette Z06 in-depth, there are so many impressive parts about the new mid-engine supercar that we figured we’d dedicate a post to going over all of its performance statistics. So without wasting any more time, let’s get into the numbers and see what makes the latest addition to the long-running Corvette lineage so impressive.
We’ll start with what is arguably the most important part of the 2023 Corvette Z06: the powertrain. The beating heart of the supercar is GM’s new dual overhead cam, flat-plane crank LT6 V8 engine. This motor has a bore of 4.104 inches and a stroke of 3.150 inches, giving it a total displacement of 5.5 liters. The block is made of A319-T7 sand-cast aluminum and features pressed-in iron cylinder liners and four-bolt main bearing caps and is joined by A356 T6 cast aluminum heads. Output is rated at a GM-estimated 670 horsepower at 8,400 rpm and 460 pound-feet of torque at 6,300 rpm. Power is sent to the rear wheels through a Tremec-designed and built eight-speed dual-clutch transmission, which features a shorter 5.56:1 final drive ratio in the Z06.
