Pricing configurator: https://www.chevrolet.com/upcoming-vehi ... lt-pricing

I like they way they do options. You start with 1LT, 2LT or 3LT. And then it seems like everything is pretty much a la carte. You can get a 1LT with Z51 and the FE4 MR suspension. Or a 3LT with no Z51, no performance exhaust and no MR shocks. And everything in between - sort of like it used to be in the old school. That is pretty awesome. And they way they did this I think the average transaction prices are going to be a lot higher than the C7 even though you can still get a base one for $60k. It will inspire people to get crazy with options because you can really personalize. It may also inspire someone to buy new (vs used) because it isn't like there will basically just be 2 versions of the car floating around (say, base and Z51 the way the Stingray launched in 2014). For launching with a single engine there will be a LOT of different versions of C8s on the road, between all these options and colors and stuff.

Oh and I did verify that Z51 comes with the $1,195 performance exhaust, making it an even better deal at only $5k. You do need to spend $65k MSRP to get your sub-3s 0-60 but that is...still amazing. Problem is, if you check Z51, you really need the FE4 MR shocks which is $1,895. So that would be nearly $67k on a 1LT. Still a hell of a lot of car for the money.

Lots of good discussion. Summary:
- For C8 Z06, expect a twin turbo DOHC V8 with a flat plane crank
- Expect displacement between 4.2 (bigger than Blackwing) and 5.5L (current C7.R but also it was mentioned that even Ford's Voodoo is too large for a flat plane V8 at 5.2L). Reason it will be larger than 4.2L is to enlarge the bore to possibly make it over square. It is under square now. I did not attempt any math to see what displacements are possible. But the point is it may keep the same stroke. Or...it won't.
- The LT4 was 650 so...I guess I'd expect more output. C6 ZR1 was 638 in 2009 and then the C7 Z06 came in at 650 in 2015. C7 ZR1 is 755hp. So...this could land somewhere in the 800 hp range if past history is any indication of future performance...

I do not expect a manual with this engine. If anything I would have expected a manual with the base C8. It has an LT2 and with a manual it would have at least been an olive branch (and a compelling Grand Sport) for the old school people who are a little confused about mid engines and dual clutch transmissions. And overhead cams now. Then again, when I say old school, I probably mean "old" in which case a lot of automatics were being purchased and the new transmission probably drives just fine in automatic mode...so what do they care.

So maybe that's my prediction. Let's see a Grand Sport (typical Z06 running gear with the base LT2) and give us a manual trans. Go ahead and charge Grand Sport prices, I still want to see it and I know the car will be excellent because even the C6 Grand Sport was good (by the time it appeared in 2010 they had worked out Z06 handling issues, plus the ZR1 had a model year in the wild to further debug the platform in general). They don't make headlines having poor price to horsepower ratios but are the Corvettes to buy if you actually want to run the thing hard on a track or even the street.

C6 tangent:
Grand Sport
The 2010 Grand Sport was unveiled at the 12th annual C5/C6 Corvette Birthday Bash, held at the National Corvette Museum.[20] The Grand Sport replaces the previous Z51 option. The GS or Grand Sport was equipped with the following enhancements:
Specific manual transmission with different gear ratios
Larger/stiffer anti-sway bars
Stiffer springs
Revised shocks
Larger Z06 rear spoiler
Transmission cooler
Functional front and rear brake ducts for added brake system cooling
Unique light weight forged aluminum 18-inch front and 19-inch rear wheels (painted finish standard and chromed finish optional)
Z06 brakes, including cross-drilled 355 mm (14.0 in) front rotors and 340 mm (13 in) rear rotors
Specific rear axle ratio on automatic transmission equipped models
Optional 1LT, 2LT, 3LT and 4LT trim packages.
Wider front and rear fenders with integrated Grand Sport badges
Wider 275/35ZR18 tires in the front
Wider 325/30ZR19 tires in the rear
6-piston front calipers and 4-piston rear calipers
Dry-sump oil system (manual transmission coupes only)
Hand-built LS3 6.2 L V8 (manual transmission coupes only)
launch control (manual only)
The part about hand built LS3 with a dry sump is particularly interesting. Special cars. Like I said, even the C6 GS was good. Some LL times:
2013 Camaro ZL1: 2:57.5
2007 C6 Z06: 2:58.2
2010 C6 GS: 2:58.8
2016 ATS-V: 2:59.2
2006 Ford GT: 3:00.7
2006 C6 Z06: 3:01.1 (this car was yet to be sorted out, see the next one)
2008 C6 Z51: 3:01.2
2013 Camaro SS 1LE: 3:01.5
2007 C6 Z51: 3:03.6 (ditto Z06 comment?)

It is too bad there aren't more data points because supposedly the 1LE time was bad too.

I think the bottom line truth on the manual thing is, the majority of the people bitching about no manual were going to be prospective used C8 buyers, not new C8 buyers. It really doesn't matter what the used car (i.e. Jalopnik crowd) buyer wants if they don't have an initial sale at a dealership. I mean I'm in the same boat. And what that suggests is, very little ACTUAL lost sales despite a lot of noise and moaning.

Hmm. Disappointed about this dry weight thing. That's a little weak considering GM has been honest in the past about stuff like this from a pre-launch standpoint.
Opting for the drop-top variant of the 2020 Chevrolet Corvette C8 doesn't appear to come with a massive increase in weight. A booklet posted on Corvette Forum indicates that the C8 convertible is only 102 pounds heavier than a standard Corvette C8 coupe, which checks in at 3,535 pounds including fluids. Previously, GM only gave us the C8 Corvette's dry weight (3,366 pounds). The C8 coupe itself is only slightly heavier than the C7 Corvette Stingray; the long-term C7 we had in our fleet weighed 3,480 pounds. Opting for the Z51 package adds 42 pounds to the C8 coupe's overall curb weight, reducing the difference to 60 pounds versus a standard convertible. We don't know if the 2020 Chevrolet Corvette C8 convertible will be available with the Z51 package, but if it is you can expect all of those go-fast parts to adds slightly more heft.
3,535 is pretty much right in the meat of what I would have predicted.

But, my 1/4 mile prediction was still right on the mark despite that:
Another interesting detail from the booklet is the 2020 Chevrolet Corvette C8's quarter mile time of 11.3 seconds at 121 mph. That's only 0.3 second slower than the 755-hp C7 Corvette ZR1, which finished the quarter mile in 11.0 seconds flat. However, the ZR1 was clocked at 131.8 mph when it crossed the finish line, which is 10.8 mph faster than GM's estimates for the 2020 Corvette C8. Other vehicles that the C8 Corvette matches in the quarter mile include a 2018 Porsche 911 GT3, 2018 BMW M5, and 2018 Mercedes-AMG GT R.
And here is what I predicted:
Given slightly less weight, way more traction, an extra 35 hp AND a very quick shifting DCT, I think there is a good chance the new one will do in the 11.5 @ 121 range. I might broaden that slightly to a range of 11.2 to 11.6 for the ET, and traps of 120-122 or so. This is approaching C6 Z06 territory, and thus C7 Z06 territory. C/D got 11.1 sec @ 127 mph from a 2015 Z06 A8.
That is damn close!

Easter Eggs if you are into these kinds of details:

Seems like less than previous Corvettes but probably more than any other midengined sports car on the market.
