Here's why the 2023 Chevrolet Corvette Z06's flat-plane crank V8 is a big deal
Fox News
Corvette chief engineer Josh Holder explains why the 2023 Chevrolet Corvette Z06 has a racing-style flat-plane crank V8 and how they made it work.
That's because it features a flat-plane crank design usually associated with racing cars or the highest performance supercars, which the Z06 aims to be.
But what exactly is a flat-plane crank?
It's all about how the pistons are attached to the crankshaft. A typical V8 uses a cross-plane crank that has the journals that the connecting rods are connected to at 90-degree angles to each other, like a plus sign, while a flat-plane crank puts them at 180-degrees. You can see the difference below.
