So now that the 2018 Corvette ZR1 has been spied at the Nurburgring, video of the cars at the track are starting to show up on YouTube. One of the major unknowns is the ZR1’s powerplant. Will it be a supersized version of the supercharged LT4 or will we see a dual overhead cam LT5 as has been rumored to be in the works? Perhaps this video will finally start answering that question.
In the videos, the two known Coupe variants of the ZR1 are shown, the big wing ZR1 and a ZR1 prototype with the smaller wing.
Take a listen to this 2018 ZR1 prototype at the Nurburgring ring and check out the unconventional tail pipe set up on the big wing Corvette.
Autoevolution reports that automotive prototypes are limited to 100 decibels on the track, and it looks like this improvised exhaust set-up was designed to mute the ZR1 prototype’s sound so it could proceed with testing. As you’re watching, take a listen of a drive-by starting at :55 seconds and see if you hear the tell-tale sound of a supercharger:
According to one of our followers on Facebook, the bizarre exhaust plumbing is most likely an old industry trick used to point the exhaust sound away from any track-sound-monitoring equipment that is installed on the right side of the track.
Another sound you might hear is the scraping of the front splitter as the car brakes heavily for certain corners.
The smaller wing Corvette ZR1 prototype sounds almost domesticated when compared to the big wing Corvette and the smaller wing ZR1’s tail pipes do not have the sound dampers added. Another small difference we also noticed is that the front honeycomb grill appears to be gray instead of black.
GM hasn’t given any hints as to when the wraps will be taken off these prototypes and revealed to the world. Given the fact that this prototype is looking more and more like a dedicated track Corvette, a reveal at one of the IMSA races over the summer or early fall may be the most likely venue. In the meantime, videos like this will have to suffice.
