It still wears the extended rear pipes that quiet the car down at the 'Ring.

Chevrolet’s ongoing development of the Corvette ZR1 continues to stoke interest in this hardcore sports coupe. A new spy video from the Nürburgring Nordschleife shows off the Bowtie’s progress on the model’s engineering and lets us hear the snarling V8.

Evidence points to the ZR1 using General Motors’ new 6.2-liter V8 with the internal designation LT5. The automaker’s listing for the powerplant indicates that it has dual overhead cams, rather than the Vette’s traditional pushrods, with variable valve timing. The mill also uses aluminum construction. The ZR1’s engine likely eclipses the 650 horsepower from the Z06’s LT4 supercharged 6.2-liter V8, but the LT5’s exact output remains a mystery. 

 

Update:

 

The LT5 is so loud that Chevy’s engineers at the ‘Ring fit the ZR1 test mule with a bizarre set of extended exhausts. The engine already has a distinct snarl in his clip. Uncorking the pipes for the production version could result in an even meaner roar.

The ZR1’s engineers take a form-follows-function approach to the C7 Corvette’s already lithe shape. The front gains a road-scraping splitter and much larger intakes. The hood gains a distinct power bulge for fitting the new engine, and the fender vents behind the front wheels appear to be even larger than on the Z06. There’s also a gargantuan wing sitting on the rear deck. However, spy shots have also shown a smaller version at the back, indicating the bigger unit might be optional.

Rumors indicate that the ZR1 might debut in early August at IMSA’s Continental Tire Road Race Showcase at Road America in Elkhart Lake, Wisconsin. If this report is accurate, then Chevy only has a few more weeks of testing before the hardcore model’s official premiere. Spy photos also indicate that a convertible version could join the lineup later.

The ZR1 could be something really special because it might be the last front-engine Corvette for the foreseeable future because Chevy has the future mid-engine 'Vette under development at the same time.
