2018 Corvette ZR1 Spotting Testing At The ‘Ring



As the quintessential testing ground for new models, it was only a matter of time until Chevrolet puts their 2018 Corvette ZR1 to the test at the Nürburgring Nordschleife.

What’s interesting about the video below are the odd pipes attached to the ZR1’s center-exit exhaust. Those are actually large exhaust dampers to quiet the car down. According to Stateside Super Cars, Nürburgring has a maximum noise limit of 100 decibels during industry testing, meaning the ZR1 is louder than that without the dampers.

Great news for enthusiasts who loves loud exhausts, but recent spy shots of the ZR1 testing at Nürburgring shows a lack of dampers. Perhaps Chevrolet has made some changes to the prototype’s exhaust.



Whatever the case, speculations suggests that the ZR1 could be powered by a LT4 V8 engine coupled with a supercharger. We may even see the all-new LT5 DOHC V8 engine under its bonnet with a 10-speed automatic transmission.

Chevy is expected to unveil the ZR1 later this year, perhaps at the IMSA Continental Tire Road Race Showcase this august.

Doubt it'll be the rumored LT5 in there. It would make more sense to reveal that new engine with the new setup on the C8.

I doubt it as well. The whole hype around the C8 other than it being mid-engined is the return of the notorious LT5 nameplate. Why waste it on the C7 ?

0:43 and on it just sounds amazing, and that's just within the lower RPM range as it transitions from one turn to another.

An Akra titanium setup should go a long way to open it up even further:

I'm more of an open header or straight pipe kinda guy, I'm not too sure. That does sound great and it's a common one a lot of people go for, but it's not my ideal setup.

I prefer the open header thing but not for daily driving as you'll attract a lot of attention, a lot of times, not the good attention. I'd rather take the route of installing electronic exhaust cutouts in order to be able to control it. That being said, I would want those right off of the header collector.

But this being mid-engined, there really isn't going to be much exhaust plumbing there so I can already expect some sort of valvetronic exhaust system in there.

Attention is definitely a kicker and I'm pretty sure running a straight pipe on the mid-engine setup is essentially good enough to be an exhaust cutout. How soon are you really going to cut it haha?!

How the exhaust is designed will depend on what a sound engineer requires to create the sound they desire. Sometimes certain shapes and configurations are required. Not everyone does it that way but typically the high end systems do.

For sure, but it'll essentially have a loop or two to get cats in the mix and what not. Being a mid-engine setup there really isn't room to add a lot of components. Especially being a V8, you now have two exhaust manifolds to deal with and that's a good amount of piping to stuff away.
