C8 Z06 Bouncing around Europe

The 2023 C8 Corvette Z06's makeup may be one of the worst-kept secrets in automotive history. Figured out years ago that it'd have a howling V8 with overhead cams and a flat-plane crankshaft, and not to mention a serious rear wing.
(notice how wide the rear tires are, like 345/25/20)

All that remained was to hear, see, and drive the car, and we're now past the second phase of that, as a nearly undisguised prototype has been photographed outside the Nürburgring.
This photo depicts the first Z06 mule we've seen without the sort of baggy, body-obscuring camouflage it wore while being seemingly benchmarked against the Porsche 911 GT2 RS.

They were snapped as the car circled a roundabout, so we now have a perfect, nearly 360-degree picture of the new Z06.
Up front are a sizable splitter and big canards (or dive planes), leading to a redesigned front bumper which sits dual heat exchangers, one on each side.
Larger, more sharply angled rear fender intakes are obvious from the side, as are more aggressive skirts and, behind five-spoke wheels, colossal brakes both front and rear.
The front's rotors appear to be possibly drilled, though the photos aren't quite detailed enough to conclude they are.

Out back is a deeply dished rear wing atop a restyled rear bumper, the most significant change to which is the return of the center-exit quad exhaust used on the C5 through C7.
The sound that comes there from will be, as Chevy has revealed, remarkably close to that of a Ferrari 458 whether you consider it a supercar or not, it'll sure sound like one.
GM has confirmed the Corvette Z06 will debut this autumn and hit the market as a 2023 model, so it won't be in customers' hands for more than a year.
By then, we may have a better grasp of C8 models yet to come, which have been rumored to include a Grand Sport, all-wheel-drive E-Ray hybrid, twin-turbo ZR1, and even hyper-Vette called the Zora.

Whatever the case, the Z06 has whetted our appetites for the future of the Corvette, and it just might set the standard for supercars the world over.
Chevy's mid-engine Corvette C8 may not be a secret anymore, but sightings of camouflaged prototypes have continued unabated.
Footage of one test mule emitting an unusual exhaust note kicked up speculation that General Motors is testing the C8's first high-performance variant, thought to be the Z06, and the photo seen above, taken Tuesday, adds fuel to that fire.

This photo depicts a camouflaged C8 prototype alongside a 691-horsepower Porsche 911 GT2 RS, holder of lap records from Wisconsin's Road America to Germany's Nürburgring (albeit in modified form).
Both the image's poster and a commenter reported spotting these two cars traveling together in California; the former recalled seeing them at "high altitude up in the mountains of California, 4,200 feet," while the latter specified Westmorland, California as the area where they saw the pair.

Benchmarking what we'll assume is the Z06 against the now-defunct GT2 RS may seem like an uneven comparison, but recent rumors regarding the Z06's performance capabilities suggest the two could be closer in performance than you may think.

The twin-cam, flat-plane-crank V8 derived from the C8.R race car that's expected to power the Z06 is rumored to produce at least 600 horsepower, possibly more, and at least 500 ft/lbs torque.
Z06s could also allegedly feature aerodynamics more extreme than the last-generation ZR1, with larger rear wings that generate both more downforce and less drag than the C7 ZR1's did.

Regardless of how true that rumor is, it's clear that GM is shooting for the moon with high-performance C8 variants.
And as the saying goes, even if GM misses its mark, it'll land among the stars anyway.

Hard to keep up as testing is also being done with the hybrid C8 happening at the same time

Only 600-650 horsepower?!.. thats not nearly enough, this is 2021 not 2011.. it needs to be 1000 plus..
even GM's new Hummer pick up truck will have a 1000 horsepower version..
Bring on the C8 hybrid.

1000 horse sounds like a worthwhile 'goal' and its admirable that any production vehicle can 'supposedly' achieve that figure. I say 'supposedly' because you'll rarely (if ever) actually get your 1000hp......the eca and car systems just won't let it happen. In most situations what kind of power and associated torque will totally overwhelm the tyres. We are now seeing that with modified electric vehicles......the torque produced without some form of electronic traction control intervention just 'frys' the tyres - and much the same with all wheel drive vehicles.

Absolutely... all wheel drive and traction control that actually works (like on my Tesla but unlike the completely useless TC on my Nissan van) are a must to put 1000 plus horsepower to the road. Corvette need to up their game or they will be humiliated by four door saloons and crew cab pick up trucks.

The existing DCT design would not be able to support a big increase in Hp/Tq and for the 1st year of the new flat plane crank engine
The dual clutches design has now just would not support more torque

GM will keep the numbers lower to get engine well worked out with first production year

High numbers will be coming when the hybrid model comes out following year and then the turbos added

Those going to this weekend's 24 hours of Le Mans, bring a camera or video with and get more shots of the test C8 Z06

Here is the Rimac Nevera putting down 1914 horsepower and 1740 ft lb of torque on an unprepped surface to do an 8.62 second quarter mile..
All wheel drive and effective traction control.

Proof of how serious OEM's are taking the potentially extreme torque on electric and hybrids. My BMW 225XE auto plug-in hybrid had a 3 cylinder 1500cc turbo engine for IC drive (detuned version of I8 engine) plus the battery drive giving total of 221 bhp and low 6 second 0-60's. Torque was sufficient in damp conditions to get momentary wheelspin from from engine driven wheels and rear battery powered wheels (until car's system detected and stopped it).........the point I am getting to is that the vehicle although not particularly fast in top speed terms (120mph?) came supplied with 'Z' rated tyres, reflecting the huge torque these vehicles can put down on the tarmac.......

My base entry level Tesla (cheapest, 'slowest' car they make) is just shy of 300 horsepower and rear wheel drive only, no all wheel drive on this one, but you can smash your foot down at any speed in any conditions, even turning, and (so far) the traction control just looks after everything. It never spins the wheels or gets out of shape but as soon as it has traction as you come out of the turn it launches you.. 0-60 in just over 5 seconds. I dont pin it all the time, usually i regulate the throttle myself but whenever i have tried it im completely amazed at the witchcraft going on. Its doesnt just ineffectively dull the power like the Nissan, you can feel it searching for traction and putting the maximum power it can through without lighting up the tyres (Michelin PS4s).

0-60 in 2.3 secs 1020 hp on wet road..
