After years of speculating what kind of miracles Chevy will be able to wring out of the eighth-generation mid-engine Corvette Z06, the world will finally get the inside story when the 2023 model is unveiled in October.
In the meantime, however, the folks at Hagerty are offering up a preview of three, and possibly four, production-car records for naturally aspirated V8 engines that the new Z06 has a chance of breaking.
First of all, its expected 5.5-liter (336 cubic inch) engine would be the largest-displacement flat-plane V8, surpassing the 2015-20 Ford Shelby GT350’s 5.2 liters.
Next record that may fall: most torque from a naturally aspirated flat-plane V8, with Hagerty predicting as much as 500 lb-ft for the new Z06, up considerably from the current record of 429 lb-ft from the above Shelby GT350.
A third possible record: highest redline in an American performance car, currently owned by the GT350 at 8250 RPM. Hagerty believes the new Z06 could hit a redline of 9000 RPM.
A fourth record could happen but is less likely, Hagerty notes. The 2015-17 Dodge Viper and its 8.4-liter V10 is the most powerful naturally aspirated American engine at 645 horsepower, well ahead of the 526 horsepower of the runner-up GT350 and GM’s best of 505 horsepower out of the 7.0-liter LS7 in the C6 Z06. Current predictions, according to Hagerty, show the new Z06 landing between 600 and 650 horsepower, though they believe it’s unlikely to match the supercharged C7 Z06’s 650 horsepower, especially amid current rumors of about 617 horsepower.
Regardless of how many records the Z06 sets, we’re sure it’ll be a very welcome – and powerful – addition to the Corvette lineup.
