For all of us wondering how the C8 Z06 normally aspirated engine makes more power than the outgoing C7 Z06 super-charged engine then this video is for you. Or for that matter anybody who appreciates engineering analysis.



We have known that the C8 Z06 would feature a 5.5-liter naturally-aspirated V8 ever since the Corvette C8.R race car was unveiled with this same basic engine in October 2019. Recent rumors suggested the engine would be tuned to around the 617 hp mark for the Z06, so you can imagine our surprise when the car was announced with no less than 670 hp and 460 lb-ft (623 Nm).

That horsepower figure makes this 5.5-liter flat-plane crank engine the most powerful naturally-aspirated V8 ever used by a production car. It also gives the new car a 20 hp advantage over the 6.2-liter supercharged V8 used by the C7 Z06. Just how was Chevy able to extract so much power from this smaller-capacity engine without relying on forced induction? See the "Engineering-Explained" video at the link above.
