- gm authority captured a video of what is likely the c8 corvette z06 testing outside gm's milford proving ground in michigan.
- the engine sound we hear is higher-pitched and smoother, meaning it has a flat-plane-crank v-8, which will power the upcoming high-performance c8 variants.
- we expect that the new z06 will be powered by a naturally aspirated flat-plane-crank 5.5-liter v-8.
there are a few high-performance c8 corvette models on the way, including the z06 and zr1 as well as a hybrid model. several of those upcoming performance models will be powered by a rather special engine: a flat-plane-crank v-8. in the z06, it will be naturally aspirated, and it'll provide some satisfying, ferrari-like shrieks. we've seen and heard it testing on curvy mountain roads, but now we've heard it accelerating in a straight line
the website gm authority captured a video of a highly camouflaged c8 prototype testing outside gm's proving ground, and the high-pitched sound immediately pointed suspicions toward the upcoming c8 z06. this is something you'll want to watch over and over again just to hear the glorious flat-plane-crank v-8 sing.
we say it's a flat-plane-crank over a cross-plane v-8 because the sound is higher-pitched and smoother than the latter. we can't quite tell if it's turbocharged, so it's likely the naturally aspirated z06 and not the coming zr1, which will use forced induction. both of these high-performance vettes will utilize a 5.5-liter flat-plane-crank v-8. the z06 is expected to put out more than 600 horsepower, while the twin-turbocharged zr1 should have around 800 horses.
there will also be a hybrid model, likely to be named eray or zora, which will use the twin-turbo 5.5-liter in conjunction with a front-mounted electric motor, and it could approach 1000 horsepower. we're eagerly awaiting more information about the coming c8 corvette models, but for now we'll just listen to this video on repeat.
