A few years ago, during the darkest hours of the GM bankruptcy, Corvette
 chief engineer Tadge Juechter found himself on a conference call with 
company execs and government overseers. A conversation on the bolts and 
screws of bailing out GM suddenly halted when one of the federales, a 
Corvette fan, wanted to know the plan for the C7. “At the time, there 
was no plan,” recalled Juechter as we stood trackside at Road Atlanta 
this past October. “We were at full stop.”
So much has happened since then. Flash-forward to 2014 and the scene of 
our own technical director, Don Sherman, banging on the door of 
Juechter’s home like some marauding zombie early one summer Saturday, 
intent on hand-delivering our October issue, which featured an exposé on the C8 Corvette.  And to our later meeting at Road Atlanta, where the new Z06
 sat freshly unwrapped and awaiting its ritual molestation by car 
writers. Whatever satisfaction an engineer derives from his or her ideas
 becoming realized, from seeing mere talk and drawings evolve into a 
finished product, must increase tenfold in the Corvette program, once an
 idle afterthought in the mayhem of a bankruptcy and now a full line of 
highly acclaimed vehicles.
A line that includes a 650-hp thunder wagon with the sophistication and 
poise of the world’s best sports cars. There, we said it. The Z06 must 
be ranked among the world’s best. You know that we here at 
Car and Driver
 are not idle flatterers, our job being to find the faults for you in 
haste, before you have to live with them at leisure over 72 months of 
payments. However, the Z06 completely fulfills its mission to be a super
 Corvette. It is an accessible American fantasy intended to inject joy 
and fascination and, let’s face it, a healthy dose of awe into the 
driving experience, such that there’s not much left to shout about 
except details.
Details such as a 60-mph nuking of three seconds flat, set by a Z06 
equipped with the Z07 Performance package and an automatic. This car 
tore the quarter-mile a new one at 11.1 seconds at 127 mph, scorched the
 skidpad with 1.19 g’s of grip, and stopped from 70 in an astonishing 
128 feet, the latter two figures setting 
C/D records for a production car. We also tested a slightly less potent manual-trans Z06 
Please pause here for an important message about tires. If you’ve 
followed our preview coverage, you already know that there are now a lot
 of Z06s to choose from. There are coupe and convertible body styles. 
There are two transmissions, a seven-speed manual with automatic rev 
matching and an eight-speed automatic. And there are three trim levels, 
dozens of options, and three separate aero packages. Then there’s the 
mega Z07 Performance package that further weaponizes the car with 
carbon-ceramic brakes, a carbon-fiber aero package, a slightly revised 
suspension tune, and different tires. The Z07’s run-flat Michelin Pilot 
Sport Cup 2 summer almost-slicks replace the base run-flat Michelin 
Pilot Super Sports and are, to borrow from Mark Twain, the difference 
between the lightning bug and the lightning. 
Back to the test numbers: Um, holy crap. Riding a Z06 through the first 
four gears feels like putting a saddle on Superman, though the Z06 is 
200 pounds heavier than the old ZR1.
 Obviously, there’s a squidge more power, but this is down to the race 
tires and the fact that today’s automatics are often faster than manuals
 in a straight line. We didn’t even use launch control, a simple 
flat-foot drop in full auto mode being all that was needed to produce 
these fireworks from the test equipment.
The Z06 we photographed was fully loaded with the Z07 package, Stage 3 
carbon aero trim kit, and optional carbon-kablooey interior.
 As 
you can see, there’s a Z06 for, well, if not exactly everyone, then a 
wider swath of humanity’s more impatient drivers, all of whom will be 
swamped by admirers at parties. Prepare for the eager smiles of your 
audience to droop slightly when you say you bought the automatic, as up 
to 70 percent of Z06 buyers are expected to do. This is a natural, 
instinctual disappointment, conditioned by the expectation that real 
sports cars have sticks, mounting evidence to the contrary 
notwithstanding. 
We drove both the manual and the automatic Z06 and feel that the stick, 
with its notably soft and seamless clutch takeup, is still the best 
choice. Rev matching sounds like a hateful automation of the 
heel-and-toe skill until you get used to it. Then you wonder why all 
manuals don’t have it. Or just turn it off. Or use it to learn proper 
rev matching and then turn it off. 
The automatic gets its robot chores done efficiently, but it’s the one 
area where we found the Z06 falls a little short of its billing. GM 
claims that the automatic does the work of the manual by quickly 
intuiting your intentions and behaving like a racer, taking data from 
the throttle, steering, and yaw sensors to determine whether a 
gearchange is possible or likely to unsettle the car. It does that 
fairly well, but when you’re really playing racer boy, the auto can get 
caught in the wrong gear, especially if you like left-foot braking and 
easing off the binders while simultaneously squeezing on the power. That
 sends ones and zeros up the transmission’s snoot that it doesn’t like.
Chevy’s choice of wild, bucking Road Atlanta as a launch venue proved 
both wise and a bit brave. This fast but highly technical track let the 
Z06 stretch its legs all the way up to 150-plus mph on the back 
straight, while also taxing its suspension and grip over crests and 
curbs. The Z06 immediately showed itself to be a Corvette Plus: plus 
more speed, more grip, more hunkered-down stability at triple digits, 
more noise, and a lot more stopping power.
When it’s not producing circa-30 mpg in cylinder-deactivation (eco) 
mode, the direct-injected LT4 is a typhoon of noise and power. Muffler 
flaps that bang open under hard acceleration (or stay open in track 
mode) release the crackling furies as you make the jump to hyperspace. 
Shifts are accompanied by a buzz-bang from stuttered spark and loose 
fuel. You do have to be competent before you’re attacking turns with 
anywhere near the Z06’s peak grip, especially on the gluey Cup 2s. The 
car’s eagerness to change direction stands in confounding contrast to 
its 106.7-inch school-bus wheelbase, more than 10 inches longer than a 911’s.
 No doubt our Z06 was set to the “track alignment” mentioned in the 
owner’s manual, which suggests an extra degree of negative front and 
rear wheel camber. Juechter said Chevy tries to set its press cars up 
with the track alignment when it knows they are headed to a circuit, as 
this Z06 was. 
It’s precisely the Corvette’s long inseam that gives it stability over 
curbs and pavement pitches that would upset a shorter car. That and 
shock-tuning sophistication (engineers were fussing with the 
magnetic-shock maps right up until our drive, deciding to relax them 
slightly in track mode) let the chassis digest the worst the road can 
deliver. The Z06 eats track curbs and moves on. Stability. That’s the 
word on your quavering lips when you emerge after the first session. 
But the newest Vette is a complicated toy that will take many, many 
hours of play to fully reveal itself. The traction- and 
stability-control modes affect many parameters now, including throttle 
aggression, the electronic limited-slip differential engagement, the 
magnetic shocks, and the automatic’s shift speed. You can push buttons 
and twist knobs in the pits for quite a while before you’ve explored all
 the combinations. The important take-away is this: You, Bo-Bob Racer, 
can pound the snot out of the Z06 with your manly lapping technique, 
then reconfigure the car for your rookie squire with absolutely no fear 
of him being in any danger—as long as no one fools with the buttons. 
MG’s motto used to be “Safety Fast.” It applies much better to the Z06. 
Afterward, if you’ve optioned the Performance Data Recorder that comes 
with the navigation system, you and your team can watch the video replay
 of your exploits, complete with speed, rpm, g’s, track position (thanks
 to integrated GPS data), and lap times. The Z06 isn’t merely swift; 
it’s designed specifically to make you a better driver through the 
stair-step configurability of its controls and its onboard learning 
tools. 
The Z06 does not transcend its roots; it’s still a Stingray, meaning 
wide, batwinged, loud, and full of numerous types of plastic. But once 
you’ve peeled back its many layers, the performance is that of a true 
supercar and yet another step forward for the American Dream Machine.
