If these spy shots are any indication, then the Chevrolet Corvette ZR1 will be very loud. A prototype was just caught testing on the Nürburgring Nordschleife, and engineers had to rig up some extra piping on the exhaust to muffle its growl.
Many race tracks have noise ordinances in place that restrict how loud you can be at certain times. According to our shooter, the day this prototype was caught there was a 100-decibel limit in effect. The ZR1 apparently couldn’t meet that, as extra piping was added to the tailpipes – a trick used by racers to reduce noise on noise-restricted track days. Each of the test mule’s four bazooka-sized exhaust tips is fitted with a pipe angled at 90 degrees, with the outer tips getting longer pipes.
Exactly what makes the ZR1 so loud remains to be seen. A further evolution of the Z06’s supercharged 6.2-liter LT4 V-8 would make sense, but there have also been rumors of a new twin-turbo version. GM also let slip that a naturally aspirated dual-overhead-cam LT5 6.2-liter V-8 is destined for the Corvette in 2018, though we believe that engine will show up in the mid-engine Corvette. Whatever the case, expect the ZR1 to make more than the Z06’s 650 hp and 650 lb-ft of torque.

The 600hp club. Pretty cool. The 700hp club is slightly cooler like the McLaren 720S.
BAMs have long been used in noise passby testing to help in assessing wind noise v. tire noise v. exhaust noise during vehicle development.
I remember the Spring of 1964. Several of us qualified for the State track meet which back then was held at the University of Florida.
The first night our coach took us to see “From Russia With Love’. None of us really knew who James Bond was but one guy had read the book. There were college students in line all the way around the corner of a block.
I saw Corvettes everywhere. Bunch of rich kids. I don’t remember how we could tell but some of them were fuel injected 327s. I bet they would still be hot.
The vette is at least somewhat affordable.
The 700hp club was cool until those loud, and cheap rubes of the Car World entered it, the Dodge Hellcats.
;)
The Koenigsegg One:1 got red flagged on a different European test track for exceeding the noise restriction. Funny thing was, they had only introduced the rule that morning.

As long as they don’t take on a Honda Accord ...
“Whatever happened to affordable performance? “
Base vette is just north of 50k.

Demon! 800hp club.
I went to the University of Florida and graduated in 1982 with a BS Electrical Engineering. I did not see corvettes at that time.
The price of a ZO6 will come down now. That’s how the vette game is played.
According to Dodge, the Challenger Hellcat with an eight-speed automatic transmission can hit 60 mph from a standstill in the low 3-second range and reach a top speed of 199 mph.
Yeah...but for about $10 versus several hundred thousand for the McClaren.

A 64 Corvette with a fuel injected engine had 375 HP in a 3100 lbs body.
I think it could take a Honda Accord.
Been to the Ring twice, once in a new rental 911, and again in a new BMW 318i. Fortunately, I’d studied the course, previously! ==8-0
