ALISTAIR WEAVER:
Alistair Weaver here for Edmunds with the
top 10 differences between our 2020
Corvette Stingray and the new 2023 Corvette Z06. The blue car on the right
is Edmunds own C8 Corvette Stingray. We bought it last year
with our hard-earned cash. And since then, we've done
over 13,000 miles on it. You can read all about
it on the link below. Spoiler alert, actually
really big fans. On the left is a
highlighter-yellow car, the new Corvette Z06
that we've borrowed from Chevy for the day. It comes complete with the
Z07 hardcore performance pack, and promises an even bigger
dollop of performance when it goes on sale next summer. We're going to compare
the spec of each and declare a winner in each
category, which isn't nearly as straightforward as it sounds. And now without further
ado, let's get on with it. Let's start with the
bit that you probably care about most, the noise. Both these cars are
naturally aspirated V8s, not a turbocharger or
a supercharger in sight. But this, the new Z06,
has a flat plane crank. We're going to talk more
about that in a minute. So let's hear them. Fire it up, maestro,
starting with the Stingray. [ENGING REVVING] And now ladies and
gentlemen, the Corvette Z06. [ENGINGE REVVING] [ENGING BACKFIRING] Ha, ha! That's ridiculous! PRODUCER (OFF
SCREEN): So who won? ALISTAIR WEAVER: So oh, victory. Winner is the Corvette Z06. It's just outrageous. PRODUCER (OFF SCREEN):
You need new pants? ALISTAIR WEAVER: Power,
ladies and gentlemen. Well this new 5.5
liter V8, in this case, built by Brian Walker. Great job, Brian. I hope you're watching. Develops 670 horsepower. The 6.2 liter V8 in the Stingray
develops 490 horsepower. This is literally the most
powerful naturally-aspirated V8 in history. Good job, GM. Winner, Z06. Power is good. Torque, which I
probably do too much of, the Z06 developments
460 pound feet. The Stingray, 470. So it's a narrow victory
for the cartilaginous fish. Winner, Stingray, easily. Crankshaft, the Z06 is a special
flat-plane crankshaft that saves a ton of weight, helps it
rev to an extraordinary 8,600 RPM, and sound fantastic. For anywhere close
to this money, the only car that revs harder
is the Porsche 911 GT3. And that's not a V8. How hard is it to engineer
a flat-plane crank V8 for sensible-ish money? Answer, very. A few years ago, I spent time
with the Ford performance team as they developed the Mustang
GT 350, the last mainstream, sort of mainstream car
with a flat-plane crank. And that was a really tough gig. This is courageous, GM, really By contrast, the Stingray
is a more conventional cross-plane crankshaft,
which is easier to engineer, but doesn't have the ultimate
performance benefits. It redlines at 6,600 RPM. Winner, Z06. Flat-plane cranks
are race car cool. Performance, Chevy
claims the new Z06 will do 0 to 60 in just 2.6 seconds. While we recorded 3.4
seconds for our Stingray at our very own test track. Winner, Z06, but
with an asterisk. We won't know for sure,
until we test it ourselves. Brakes, wheels,
and tires, the Z06 have six piston
calipers in the front and four pistons in the rear. The Stingray has four
pistons all round and smaller Brembo rotors. But with the Z07
you see here, you get larger Brembo carbon ceramic
brakes, even says so here. And special Michelin
Pilot Sport Cup 2R tires. Now I've driven these
tires on a 911 GT3, and they're basically
hand-cut slicks, which you'd just about get
away with if you live here in Southern California. But if you live in
Michigan, you're going to need a
spare pair of boots. And you can pay a few grand more
for these awesome carbon fiber rims, which apparently
are the widest ever sold. They say 41 pounds of
unsprung mass, which is undeniably a good thing. And they are maximum,
maximum pose. Winner, Z06. But if you're going
for the Z07 pack, you're going to need a
big budget for boots. Now here's a bit of practical,
real-world, car-shopping advice. If you're going
to buy a Stingray, tick the box for the optional
magna ride suspension. It's just under two grand. We did, and we don't regret it. Honestly, that thing
rides better than many so-called, luxury sedans. The Z06 gets magna ride
suspension as standard. But it's been retuned
and serve the springs. Then, if you go for the Z07
pack, it's stiffer still. Will that compromise
the Corvette's everyday versatility? Probably. Will it be worth it? Maybe. Winner, TBC. Styling, the Z06 just looks
that little bit more alpha. Its 3.6 inches wider to
accommodate those bigger boots. And you get new front and rear
fascias, with an extra radiator here at the front. The four exhaust pipes
have also been redesigned. So instead of two at
either side of the rear, you now get four
in the middle just to wind up the Tesla fanboys. Then if you go Z07, you get that
mighty rear wing and a carbon fiber front splitter with
these so-called dive planes. Is it OTT, over the top? Well of course it is. But hey, this is a Vette. Winner, Z06. Because in a Corvette
less is always less. By the way, if
you're wondering why our C8 Corvette has a crack in
the windscreen, join the club. It broke two months ago,
when it got hit by a stone. And so far we've failed
miserably to get it fixed. GM sent out two different
windscreens, both of which arrived broken. So if you're sitting on a
windscreen for a new Corvette that you'd like
to sell us, please drop me a line to
my Instagram account @WeaverOnCars that's
@WeaverOnCars, and we'll do a deal. Frankly, we're struggling. Optional on the Z06 is
all this carbon fiber trim that will likely cost
you a couple of grand. Now decorative carbon that
doesn't help you save weight is a real pet hate of mine. Honestly, don't do it. Best to leave well alone because
otherwise the Corvette has a well-executed, high quality,
and comfortable cabin. Winner, Stingray. Because the carbon
fiber aberration isn't even an option. When the Stingray was
originally unveiled at $60,000 price tag caused a
sensation, and rightly so. This one actually set us
back 80 grand, which we think is really the sweet
spot for a Stingray. Chevy won't confirm
the price for Z06, but we reckon it'll
start at around $95,000. Then you can add on about
10,000 more for the Z07 pack, plus the carbon fiber wheels
and a few other goodies, too. This car that you
see here is probably going to be around $150,000. Now we recognize that's a load
of money by anyone standards, but consider this,
even the base price for the similarly-powered
Lamborghini Hurricane is over $200,000. Winner, a tie. All things are relative. But the Corvette is
still a relative bargain. It's no secret that we
love our Corvette Stingray. It won our Edmunds Top Rated
Award in the sports car class last year. And a year of ownership,
and 13,000 miles is done nothing to dent
our enthusiasm even if we can't get a new windshield. On paper or even sitting on
the floor behind me there, the Z06 feels like
a logical next step, with or without the Z07 pack. And of course, it
sounds fantastic But here's a cautionary tale,
part of the Stingrays appeal is its everyday versatility. And will the new harder
edge and retuned suspension compromise some of that? I guess we'll have to
wait until the spring when we finally get to
drive it to find out. Can't wait. If you enjoy this
